There are lots of efforts being made by public transport corporations to improve public vehicle occupancy
by requesting the public to use public transport over other modes of transportation. It can be noted that if
the passenger knows with high confidence that the bus is going to come, he/she will definitely wait rather
than opting for other modes of transport. Efficient information can therefore help the users to choose faster
and more easier connections which saves their time. Trends in wireless technology like Global System for
Mobile communication (GSM) and Radio Frequency Identification (RFID) have resulted in easier and
faster communication. This paper presents a vehicle tracking system by integrating both of the above
mentioned technologies. The central server uses geographic information system (GIS) to track vehicles to
display the position information on the electronic map. This paper suggests a new cost-effective way for
tracking a vehicle in public transport domain and compares proposed technique to some of the methods
advised previously for tracking public vehicles.
Intelligent Collision avoidance and monitoring system for railway using wirel...Editor IJMTER
In the current railway systems, it is becoming ever more necessary to have safety
elements in order to avoid accidents. One of the important causes that can provoke serious accidents
is the existence of obstacles on the tracks, either fixed or mobile. This project deals about one of the
efficient methods to avoid train collision and obstacle detection. A GPS system is being used to
pinpoint the location of faults on tracks. The project presents a solution, to provide an intelligent
train tracking and management system to improve the existing railway transport service. The solution
is based on powerful combination of mobile computing, Global System for Mobile Communication
(GSM), Global Positioning System (GPS) technologies and software. The inbuilt GPS module
identifies the train location with a highest accuracy and transfers the information to the central
system. The availability of the information allows the train Controller to take accurate decisions as
for the train location. Positioning data along with train speed helps the central system to identify the
possible safety issues and react to them effectively using the communication methods provided by
the system.

Public transport service is one of the most preferred
modes of transportation in today’s smart cities. People prefer
public transport mainly for the cost benefit reasons. The
problems faced by the people while using the public transport
can be overcome by the technology such as Internet of Things
(IOT). In this paper, we present how this technology can be
applied to eliminate the problems faced by the passengers of the
public bus transport service. The Internet of Things technology is
used to provide the passengers waiting at the bus stop with real
time information of the arriving buses. Information such as
arrival time, crowd density and traffic information of the
arriving buses are predetermined and provided to the passengers
waiting at the bus stop. The display boards fitted at the bus stops
provide the real time bus navigation information to the waiting
passengers. This Smart Bus Navigation system enables the
passengers to make smart decisions regarding their bus journey.
This system reduces the anxiety and the waiting time of the
passenger’s at the bus stop. The smart bus navigation system
creates a positive impact and increases the number of people who
prefer to use the public mode of transportation.
An Optimal Route Discovery using Biogeography based Optimization for Vehicula...StevePrice20
Vehicular ad hoc network (VANET) is a subdivision of the mobile ad hoc networks which uses the moving vehicles as mobile nodes to form the mobile network. In conventional vehicular communications, the restricted radio frequency bandwidth affects the network performances. Therefore, Visible Light Communication (VLC) is integrated with the growing vehicular ad hoc network to obtain high data rate and less energy consumption during the communication. In this paper, vehicular communication is integrated with visible light communication to avoid the issues caused by the restricted radio frequency bandwidth. Moreover, the Routing using Biogeography Based Optimization (RBBO) is proposed to develop an optimal route between the source vehicles to the destination. This research performs two different communications such as vehicle to vehicle and vehicle to the infrastructure. The performance of the RBBOVLC-VANET method is analyzed by means of throughput, packet delivery ratio, delay and routing overhead as well as these performances are compared with the existing method namely ant colony optimization based routing protocol. The throughput of the routing using the biogeography based optimization method is 589.763 kbps for 500 nodes which is high when compared to the existing method.

The increasing need for traffic detection system has become a vital area in both developing and developed
countries. However, it is more important to get the accurate and valuable data to give the better result
about traffic condition. For this reason, this paper proposes an approach of tracking traffic data as cheap
as possible in terms of communication, computation and energy efficient ways by using mobile phone

speed for the Traffic Detection System. The GPS sensor of mobile device will be mainly utilized to guess a
user’s transportation mode, then it integrates cloud environment to enhance the limitation of mobile device,
such as storage, energy and computing power. This system includes three main components: Client
Interface, Server process and Cloud Storage. Some tasks are carried out on the Client. Therefore, it greatly
reduces the bottleneck situation on Server side in efficient way. Most of tasks are executed on the Server
and history data are stored on the Cloud Storage. Moreover, the paper mainly uses the distance based
clustering algorithm in grouping mobile devices on the same bus to get the accurate data.

HYBRID TOA/AOA SCHEMES FOR MOBILE LOCATION IN CELLULAR COMMUNICATION SYSTEMSijasuc
Wireless location is to determine the position of the mobile station (MS) in wireless communication
networks. Due to the measurements with large errors, location schemes give poorer performance in
non-line-of-sight (NLOS) environments. This paper illustrates methods to integrate all the available
heterogeneous measurements to achieve more accurate location estimation. The proposed hybrid
schemes combine time of arrival (TOA) at seven BSs and angle of arrival (AOA) information at the
serving BS to give location estimation of the MS. The schemes mitigate the NLOS effect simply by the
weighted sum of the intersections between seven TOA circles and the AOA line without requiring priori
knowledge of NLOS error statistics. Different NLOS models were used to evaluate the proposed methods.
It is shown by the simulation results that the proposed methods provide better location accuracy
comparing with Taylor series algorithm (TSA) and the hybrid lines of position algorithm (HLOP).

This paper proposed design and implementation of trucks tracking system using GPS based on semantic web for vehicle tracking in real time. In-vehicle unit and a tracking server is used. The information is transmitted to tracking server using GSM/GPRS modem on GSM network by using SMS or using direct TCP/IP connection with tracking server through GPRS. The received SMS contain longitude and latitude that are used to locate the vehicle on the Google maps. Tracking server also has GSM/GPRS modem that receives vehicle location information via GSM network and stores this information in database. It has been explored that most of the GPS based tracking systems are user friendly, cost effective, reliable and can be easily validated through different experiments and simulations which means that tracking system will send notifications periodically to the main station about the current position of the vehicle . Moreover those tracking notifications (GPS) will be stored in the database for future revising or generating required reports.. The tracking system will be better for cars, trucks, trailers, railways, containers and boats that can be traced using GPS vehicle tracking.

Traffic Detection System is an Android application that aims at determining the behavior of traffic in a particular location. It calculates the speed of the vehicle and the level of congestion or the amount of traffic is determined on the basis of the values of sensors. If any such obstruct found, then the driver is provided an option to send messages regarding high traffic to his/her friends. After a distinct number of repeated low speed and breaks, the location of the vehicle (latitude and longitude) send to a pre-specified contact (selected in case of traffic congestion) through an SMS. This application uses the features of the Global positioning system. The Latitude, as well as the longitude of the location where traffic jams are formed, is sent to the friends of the user. The Goggle map of the location also sends to the friends. It uses the SMS Manager a functionality of Android. The friends receiving the messages will thereby avoid taking the congested route and hence the level of traffic on the congested road will decrease, and the friends will reach the destination in comparatively less time.

Prototypic Gps-Gsm Integration for Enhancing Public Transportation and Manage...IJERA Editor
This paper proposes and implements a solution for enhancing public transportation management services based on GPS and GSM. Travel time information is a vital component of many intelligent transportation systems (ITS) applications. In recent years, the number of vehicles in India has increased tremendously, leading to severe traffic congestion and pollution in urban areas, particularly during peak periods. A desirable strategy to deal with such issues is to shift more people from personal vehicles to public transport by providing better service (comfort, convenience and so on). In this proposed system we introduced advanced public transportation systems (APTS) for public service. Advanced public transportation systems (APTS) are one of the most important ITS applications, which can significantly improve the traffic situation in India. One such application will be to provide accurate information about bus arrivals to passengers, leading to reduced waiting times at bus stops. This needs a real-time data collection technique, a quick and reliable prediction technique to calculate the expected travel time based on real-time data and informing the passengers regarding the same. The scope of this proposed system is to use global positioning system data collected from public transportation buses on urban roadways in the city of Chennai, India, to predict travel times. The performance of the proposed system is found to be promising and expected to be valuable in the development of advanced public transportation systems (APTS) in India. The work presented here is one of the first attempts at real-time short-term prediction of travel time for ITS applications in Indian traffic conditions.
Intelligent GIS-Based Road Accident Analysis and Real-Time Monitoring Automat...CSCJournals
It has been a big concern for many people and government to reduce the amount of road accident specially in Malaysia since it could be a big threat to this country. Malaysian government has spent millions of money in order to reduce the number of accident occurrence through several modes of campaign. Unfortunately, from years to years the number keeps increasing. The lack of a comprehensive accident recording and analysis system in Malaysia can be effective in these kinds of problems. By making use of IRAS (Intelligent Road Accident System), the police would be control and manage whole accident events as a real-time monitoring system. This system exploits WiMAX and GPRS communications to connect to the server for transfer the specific data to the data center. This system can be used for a comprehensive intelligent GIS-based solution for accident analysis and management. The system is developed based on object and aspect oriented software design such as .NET technology.
Intelligent transportation system (ITS) is an application which provides intelligence to the transportation
and traffic management systems. Although the word ITS applies to all systems in the transportation but as
per the European union directive it is the application of Information and communication technology in the
field of transportation is defined as ITS. The communication technology has evolved greatly today from
2G/3G to long term evolution (LTE). In this paper we focus on the LTE and its application in the ITS. Since
LTE offers excellent QoS, wide area coverage and high availability it is a preferred choice for vehicle to
infrastructure (V2I) service. At the same time the LTE customer base is increasing day by day which results
in congestion and accessing the network to send or request resources becomes difficult. In this paper we
have proposed a group based node selection algorithm to reduce the preamble ID collision otherwise this
uncoordinated preamble ID transmission by vehicle node (VN) will eventually clog the network and there
will be a massive congestion and re-transmissions attempts by VNs to obtain the random access channel
(RACH).
RFID-based public transport ticketing systems
rely on widespread networks of RFID readers that locate
the user within the transport network in real time to be
able to verify whether he can travel at that time with the
ticket he holds. This paper presents a system that uses that
same RFID-based location information to give the user
navigation indications depending on his current location
provided that the user has indicated beforehand the places
he intends to visit. The system was designed to be costeffectively
deployable on the short term but open for easy
extension. This paper is based on ticketing and
identification of the passenger in the public transport. In
the metropolitan city like Mumbai, Kolkata we have a
severe malfunction of public transport and various
security problems. Firstly, there is a lot of confusion
between the passengers regarding fares which lead to
corruption, Secondly due to mismanagement of public
transport the passengers faces the problem of traffic jam,
thirdly nowadays we have severe security problems in
public transport due anti-social elements.The entire
network comprises of three modules; Base Station Module,
In-Bus Modules and Bus Stop Module. The base station
module consists of monitoring system which includes GSM
and a PC. The In-Bus Modules consists of two
Microcontrollers, GSM Modem, GPS, Zigbee, RFID, LCD
and infrared sensor. RFID for ticketing purpose, GSM,
GPS is used for mobile data transmission and tracking
location. The Zigbee module is also interfaced with the
microcontroller which is used to send the bus information
to bus stop and to get the information from the bus stop to
bus. The Bus Stop Module is fixed at every bus stop
consists of Zigbee node which is interfaced with the
Microcontroller.
Multi tracking system for vehicle using gps and gsmeSAT Journals
Abstract In the present paper a multilayered microstrip low pass filter using complementary split ring resonator is proposed. A design for prominent stop band characteristics with minimized ripples is presented, while maintaining the filter pass-band performance. By properly designing and integrating the complementary split ring resonators with the low pass filter, the proposed structure exhibit superior pass band and stop band characteristics by eliminating unwanted spurious signals. Since the literature is multi-layered, no structure is designed at the ground plane and the problem of distortion of ground plane structure while packaging is resolved. The measured results indicate that the proposed structure achieves significantly improved band characteristics with minimum distortion, when compared with the simulated one.

Online Accessable Traffic Control System for Urban Areas Using Embedded Syste...IJSRD
During recent years traffic congestion is become a serious problem in almost all cities. Due to the high density of traffic, pedestrians find it difficult to cross the road. Even though several advanced strategic plans are introduced to regulate the traffic but due to lack of provision for on- road pedestrian crossing, rate of accidents become very high. One such provision is given is elevated path for pedestrian to cross the road, but the elderly person finds it difficult to use that. Hence an idea is proposed to help the elderly people by giving provision for on- road pedestrian crossing in high density traffic areas like near schools, hospitals, markets, etc. which reduces the accidents rate also. To implement this, here an additional time delay is introduced in the traffic signal for pedestrian crossing in addition to vehicle crossing in all possible direction. Additionally, provision is given to track the vehicle which violates the traffic rules and to clear the traffic for emergency vehicles. All the above said three parameters can be simulated by using PROTEUS software.
Novel based Approach Schema for Processing Vehicle Tracking System through GP...ijtsrd
In recent years many systems are approached to track the vehicles in order to find out movement of any equipped vehicle from any location at any time. This paper implements formalised schema to develop a tracking system that is much cost effective that available in the market. Various technologies utilised are GPS Global Positioning System module to get geographic coordinates at regular time intervals. The GSM GPRS Global System Positioning General Packet Radio Service module is used to transmit and update the vehicle location to a database. The Google Maps API is used to display the vehicle position on the map in the Smartphone application. The tracking system here helps to identify the location of the college bus through our smart phone when a SMS Short Message Service is sent to a personal number thus indicating the bus location via SMS. By incorporating a GPS and GSM modem the location of the device by sending a SMS to the number specified. No external server or internet connection is used in knowing the location at user end which in return reduces the cost. We can also use this technology to reduce our time whenever we are waiting for buses by knowing their location on our mobile phones. If vehicle has been stolen then also we can track our vehicles.

A novel integrated approach for handling anomalies in RFID dataijujournal
Radio Frequency Identification (RFID) is a convenient technology employed in various applications. The
success of these RFID applications depends heavily on the quality of the data stream generated by RFID
readers. Due to various anomalies found predominantly in RFID data it limits the widespread adoption of
this technology. Our work is to eliminate the anomalies present in RFID data in an effective manner so that
it can be applied for high end applications. Our approach is a hybrid approach of middleware and
deferred because it is not always possible to remove all anomalies and redundancies in middleware. The
processing of other anomalies is deferred until the query time and cleaned by business rules. Experimental
results show that the proposed approach performs the cleaning in an effective manner compared to the
existing approaches.

quick help, less burden on caregivers, and optimized home settings. But will old folks use all this tech? Can
we prove it really helps folks live longer and better? More research on maximizing reliability and
evaluating real-world impacts is needed. But designed thoughtfully, smart homes could may profoundly
improve the aging experience.
HMR LOG ANALYZER: ANALYZE WEB APPLICATION LOGS OVER HADOOP MAPREDUCEijujournal
In today’s Internet world, log file analysis is becoming a necessary task for analyzing the customer’s
behavior in order to improve advertising and sales as well as for datasets like environment, medical,
banking system it is important to analyze the log data to get required knowledge from it. Web mining is the
process of discovering the knowledge from the web data. Log files are getting generated very fast at the
rate of 1-10 Mb/s per machine, a single data center can generate tens of terabytes of log data in a day.
These datasets are huge. In order to analyze such large datasets we need parallel processing system and
reliable data storage mechanism. Virtual database system is an effective solution for integrating the data
but it becomes inefficient for large datasets. The Hadoop framework provides reliable data storage by
Hadoop Distributed File System and MapReduce programming model which is a parallel processing
system for large datasets. Hadoop distributed file system breaks up input data and sends fractions of the
original data to several machines in hadoop cluster to hold blocks of data. This mechanism helps to
process log data in parallel using all the machines in the hadoop cluster and computes result efficiently.
The dominant approach provided by hadoop to “Store first query later”, loads the data to the Hadoop
Distributed File System and then executes queries written in Pig Latin. This approach reduces the response
time as well as the load on to the end system. This paper proposes a log analysis system using Hadoop
MapReduce which will provide accurate results in minimum response time.
SERVICE DISCOVERY – A SURVEY AND COMPARISONijujournal
With the increasing number of services in the internet, companies’ intranets, and home networks: service
discovery becomes an integral part of modern networked system. This paper provides a comprehensive
survey of major solutions for service discovery. We cover techniques and features used in existing systems.
Although a few survey articles have been published on this object, our contribution focuses on comparing
and analyzing surveyed solutions according eight prime criteria, which we have defined before. This
comparison will be helpful to determine limits of existing discovery protocols and identify future research
opportunities in service discovery.
SIX DEGREES OF SEPARATION TO IMPROVE ROUTING IN OPPORTUNISTIC NETWORKSijujournal
Opportunistic Networks are able to exploit social behavior to create connectivity opportunities. This
paradigm uses pair-wise contacts for routing messages between nodes. In this context we investigated if the
“six degrees of separation” conjecture of small-world networks can be used as a basis to route messages in
Opportunistic Networks. We propose a simple approach for routing that outperforms some popular
protocols in simulations that are carried out with real world traces using ONE simulator. We conclude that
static graph models are not suitable for underlay routing approaches in highly dynamic networks like
Opportunistic Networks without taking account of temporal factors such as time, duration and frequency of
previous encounters.

The aging population and the consequent increase in the incidence of dementias is causing many
challenges to health systems, mainly related to infrastructure, low services quality and high costs. One
solution is to provide the care at house of the patient, through of home care services. However, it is not a
trivial task, since a patient with dementia requires constant care and monitoring from a caregiver, who
suffers physical and emotional overload. In this context, this work presents an modelling for development of
pervasive systems aimed at helping the care of these patients in order to lessen the burden of the caregiver
while the patient continue to receive the necessary care.

DETERMINING THE NETWORK THROUGHPUT AND FLOW RATE USING GSR AND AAL2Rijujournal
In multi-radio wireless mesh networks, one node is eligible to transmit packets over multiple channels to
different destination nodes simultaneously. This feature of multi-radio wireless mesh network makes high
throughput for the network and increase the chance for multi path routing. This is because the multiple
channel availability for transmission decreases the probability of the most elegant problem called as
interference problem which is either of interflow and intraflow type. For avoiding the problem like
interference and maintaining the constant network performance or increasing the performance the WMN
need to consider the packet aggregation and packet forwarding. Packet aggregation is process of collecting
several packets ready for transmission and sending them to the intended recipient through the channel,
while the packet forwarding holds the hop-by-hop routing. But choosing the correct path among different
available multiple paths is most the important factor in the both case for a routing algorithm. Hence the
most challenging factor is to determine a forwarding strategy which will provide the schedule for each
node for transmission within the channel. In this research work we have tried to implement two forwarding
strategies for the multi path multi radio WMN as the approximate solution for the above said problem. We
have implemented Global State Routing (GSR) which will consider the packet forwarding concept and
Aggregation Aware Layer 2 Routing (AAL2R) which considers the both concept i.e. both packet forwarding
and packet aggregation. After the successful implementation the network performance has been measured
by means of simulation study.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

ABSTRACT
There are lots of efforts being made by public transport corporations to improve public vehicle occupancy
by requesting the public to use public transport over other modes of transportation. It can be noted that if
the passenger knows with high confidence that the bus is going to come, he/she will definitely wait rather
than opting for other modes of transport. Efficient information can therefore help the users to choose faster
and more easier connections which saves their time. Trends in wireless technology like Global System for
Mobile communication (GSM) and Radio Frequency Identification (RFID) have resulted in easier and
faster communication. This paper presents a vehicle tracking system by integrating both of the above
mentioned technologies. The central server uses geographic information system (GIS) to track vehicles to
display the position information on the electronic map. This paper suggests a new cost-effective way for
tracking a vehicle in public transport domain and compares proposed technique to some of the methods
advised previously for tracking public vehicles.
KEYWORDS
Public Vehicle Tracking, GSM, RFID
1. INTRODUCTION
One of the major problems faced by public transport systems is low occupancy rate. One reason
for this is that a passenger normally does not know the public vehicle scheduling information and
its arrival timing information at predefined stops. Thus, it is possible to motivate a passenger to
opt for public vehicles having predefined routes by providing the vehicle location and time of
arrival at respective stoppage. Large cities with fleet of vehicles require a system to determine
location of movement of passenger vehicles at a given time. The future intelligent transportation
system (ITS) will rely predominantly on several vehicle communication systems [1] including
peer-to-peer and peer-to-base station communications. Thus, this system provides the facility to
know about the time for arrival at different stops and the location of public vehicles having
predefined routes. This paper introduces a system that:
(i) provides a very cost-effective solution as compared to existing technologies for
tracking public vehicles , and
2. International Journal of UbiComp (IJU), Vol.3, No.1, January 2012
34
(ii) offers an open architecture that can be easily expanded to other applications.
In this paper, we have dealt with vehicles travelling in 2D object space. In a two-dimensional
object space, vehicles may follow two types of routes like static and dynamic. Trains generally
follow static routes as they move through intermediate stations up to destination station. Their
routes are fixed in the form of railway tracks. Public Transport usually uses fixed intra-city routes
that are static. On the other side private vehicles follow random path; they are free to choose their
path and hence their routes are dynamic.
The development and validation of the system in the present work has been carried out for the
city of Jabalpur (India) and the public transport system here, is referred as Metro buses. In this
paper, we present an extensible public vehicle position tracking system (PVPTS) that deploys
data transmission capabilities of the Global System for Mobile Communication (GSM). Our
design is extensible to bigger cities where many public vehicles are required to be simultaneously
tracked and monitored. The local bus, train arrival information can be provided to the passengers
using this system. A background of the relevant technologies used for tracking is given in Section
2. Existing technologies are discussed in Section 3; while section4 contains methodolgy. Section
5 describes the implementation of PVPTS. Section 6 discusses on low cost solution. Section 7
shows system testing and results. Section 8 compares and contrasts this system with other PVPTS
systems and concludes with a discussion on future directions for this research project.
2. BACKGROUND
The One of the possible reasons for people preferring private vehicles over public vehicles is that
a passenger normally does not have exact information about the public vehicle arrival timing at
their stops. By providing reliable public vehicle arrival information to the passengers at
predefined stops, it is expected to improve the public vehicle occupancy. This is beneficial to both
the passengers and public transport corporations. Tracking of a vehicle can be expressed as
continuously monitoring of a vehicle. Tracking of buses can be useful for the automation of
existing transportation systems [2]. By the use of tracking the information about bus-arrival
timing can be easily provided to the passengers.
The different wireless technologies available today have resulted in the reliable and faster
communication. GSM is an open, digital cellular technology used for transmitting mobile voice
and data services [3]. GSM has become the world’s fastest growing mobile communication
standard. GSM networks operate in a number of different carrier frequency ranges (separated
into GSM frequency ranges for 2G and UMTS frequency bands for 3G), with most 2G GSM
networks operating in the 900 MHz or 1800 MHz bands. The GSM network is structured into a
number of discrete sections:
(i) The Base Station Subsystem (the base stations and their controllers).
(ii) The Network and Switching Subsystem (the part of the network most similar to a fixed
network). This is sometimes also just called the core network.
(iii)The GPRS Core Network (the optional part which allows packet based Internet
connections).
(iv) The Operations support system (OSS) for maintenance of the network.
Radio-Frequency Identification (RFID) is a wireless sensor technology which is based on the
detection of electromagnetic signals [4]. There is emission of radio waves from the transmitter
which can reach up to 100 feet or more, depending on its power output and the radio frequency
3. International Journal of UbiComp (IJU), Vol.3, No.1, January 2012
35
used. RFID can be employed for different applications. RFID is used successfully in a variety of
industries for different purposes. It is used for tagging and identifying the different items in a
store. In the construction industry, RFID is used successfully for the tracking of pipe spools,
structural steel members and as an on-site support system [5, 6].
3. EXISTING TECHNOLOGIES
There are many tracking applications available in the market for tracking of various public
vehicles. One of the cost-effective technique for vehicle tracking is the ‘vehicle card’ technique
[7], which uses STD phone booths and a specially designed vehicle-card. Vehicle owner is
required to carry a card to the nearest tracking point, basically a designated STD booth on vehicle
routes, at major vehicle stops and petrol bunks. The card is coded with details of the vehicle;
these details and a simple numbered message are transferred to a local telephone number. The
receiver uploads all incoming messages by email to a central server, where it is processed and
placed on a website. In this way a vehicle can be tracked. But this scheme is not so useful for a
large scale implementation of a fully automated real-time system. Another scheme for tracking
has been proposed using odometer and inertial sensors [8]. But this technique has been proposed
specifically for train transport. It does not gives a generalized solution for all the public
transports. Similarly, there is one more technique employing distance-meter (odometer) and
cellular infrastructure which is used for tracking vehicles in public domain [9].
One popular technique on which most of the moving objects tracking schemes rely is GPS
(Global Positioning System) [10]. Most modern vehicle tracking systems use GPS modules which
is costly in usage and implementation. GPS provides specially coded satellite signals that can be
processed in a GPS receiver, enabling the receiver to compute position, velocity and time. Four
GPS satellite signals are used to compute positions in three dimensions and the time offset in the
receiver clock. GPS is the most accurate and popular positioning system. It provides a position
accuracy of around 10 meters. A clear line of sight to at least four GPS satellites is necessary for
high accuracy. GPS was developed by the U.S. Department of Defense. The system consists of a
constellation of 24 satellites orbiting around 12,000 miles above the Earth’s surface, shown in
Figure 1. GPS was dedicated solely for military use and has recently been declassified for civilian
use. The GPS receiver measures distances to four or more satellites simultaneously. GPS
receivers take this information and use triangulation to calculate the user's exact location [11].
Factors that can degrade the GPS signal and thus affect accuracy include following:
(i) Ionosphere and troposphere delays – On passing through atmosphere the satellite
signal slows down. Significantly larger delays occur for signals emitted from low
elevation satellites.
(ii) Signal multi path - Satellite navigation receivers operate by line of sight with global
positioning satellites. When GPS signal is reflected off big objects such as tall
buildings or any large mountain before it reaches the receiver there is increase in the
travel time of the signal, thereby causing errors.
(iii) Positioning errors - Generally, a satellite navigation receiver is accurate to within 10
m. A number of positioning errors can occur, limiting accuracy to within 15–25 m.
There can be orbiting errors due to which a satellite’s reported position does not
match its actual trajectory.
One of the vehicle tracking technique used for vehicle tracking is Dead-Reckoning [12], in which
the location of the vehicle is calculated by integrating the traveled distance in various directions
in relation to a known initial location, often the previous location. The traveled distance is
measured by wheel sensors; the driving direction is measured by an electronic compass. The
4. International Journal of UbiComp (IJU), Vol.3, No.1, January 2012
36
wheel sensors are also used for determining the driving direction by frequently comparing the
distance traveled by the left and the right wheel. Both obtained driving directions are compared to
compensate for the accumulating error of the wheel sensors as well as for fluctuations in the earth
magnetic field. As the measured distance and direction remain rough approximations, dead-
reckoning suffers from an accumulated error. The Travelpilot[13] is an automotive navigation
system that is use the U.S and Europe that uses dead-reckoning and map-matching for navigation.
Evaluation of currently available technologies has found that each technology affords unique
advantages for vehicle tracking applications while also facing distinctive challenges to overcome
so as to satisfy the practical requirements in terms of reliable performance and cost
effectiveness.
Figure 1. GPS consists of 24 satellites of which at least 5 can be seen from any point on the globe.

4. METHODOLOGY
The tracking of any public vehicle involves the frequent and fast communication of vehicle’s
location information. For the purpose of vehicle tracking, information needs to be passed
simultaneously at different locations so that passengers can get timely information. In all the
techniques stated previously, either hardware or software overhead is often required at cell-sites.
If vehicle routes under tracking are known in advance, a mapping system can easily trace a
specific location on any route. A GIS can be used as a multimedia visualization tool for viewing
and analyzing spatio-temporal relationships between different moving objects.
The proposed tracking system eliminates the need of additional hardware or software at cell-site.
This proposed system depends upon GSM system and RFID for its operation. In our system, we
have used the text-based data via the short message service enabled by the standard cellular phone
communication network of GSM which provides a low-cost, effective solution in an urban area
with an extensive coverage of mobile phone networks and has overcome the drawbacks of
conventional walkie-talkie systems. The main limitations of data transmission on walkie-talkie or
voice radios are:
(i) the possibility of losing data since data from multiple vehicles occupy the same radio
channel.
(ii) the limited range the voice radio can cover.
5. International Journal of UbiComp (IJU), Vol.3, No.1, January 2012

In proposed system 8 channel Radio transmitter and receiver with short range of few meters are
used to get information about the presence of vehicle near the bus stop, which is further
communicated through GSM module. In this way the system provides the information about the
timing of bus arrival/departure in a semi-online manner. Table 1 compares the proposed scheme
with other schemes such as Vehicle-card technique and Pure GPS/GPS–GPRS mixed.

The proposed system consists of two underlying technologies: GSM and RFID. Figure 2 shows
the architecture of the proposed system. The PVPTS can be divided into three parts: Vehicle
addressing and identification system, Information routing system and Display and data analysis
system.
4.1. Vehicle addressing and identification system
Every vehicle is provided an identifier so that it can be recognized and tracked easily. Every
vehicle has an 8 bit RF transmitter which is preset different for different vehicles. The RF
transmitter always remains ON so that it can be identified by RF receivers located at every bus
stop, whenever it is in proximity of few feet. The buses of same route may have same or different
transmitting code. If buses of same route are given the same code we can track buses of 256
different bus routes simultaneously. In another case where particular public vehicle has to be
tracked among the other vehicles of the same route, one or more bits out of 8 bits can be reserved
for differentiating them.
4.2. Information routing system:
GSM is the most widely used among the digital wireless telephony technologies. The PVPTS
uses Short Message Service (SMS) sent over GSM networks for routing information to different
public vehicle stops. The signals from the GSM modem are sent to nearest Base Transceiver
Station (BTS) that in turn are transferred to Mobile Switching Center (MSC) through Base
Station Controller (BSC). The GSM modem equipment has a Subscriber Identity Module (SIM)
security and authentication. The SIM is a detachable smart card containing the user's subscription

information and phone book. The BTS and BSC together constitute the Base Station Subsystem
(BSS) and perform all the functions related to the radio channel for data signaling and frequency
hopping control and power level control. All of the elements in the system combine to produce
many GSM services such as SMS which is used for information routing to different bus stops.
Figure 2. Architecture of the proposed system
4.3. Vehicle addressing and identification system
Display and data analysis system: LED displays are low cost, low power device capable of
displaying text. LED display boards usually have clear visibility. LED display devices are placed
at every bus stop, displaying the route number and time of arrival of a bus at bus stop. The vehicle
location information received through GSM Modem placed at bus stop is sent to LED displays.
The LED display periodically displays information of different buses along with time of arrival.
Data stored at the central server can be easily analyzed through an application as It receives,
processes, analyzes and stores the incoming SMS messages. The tracking of buses at central
server thus can be easily carried out by having a GSM modem connected to server PC which
updates the vehicle's location upon receiving the messages from different GSM modems placed at
different bus stops.
5. IMPLEMENTATION
Several components are used in our tracking system. For identification, every vehicle has been
provided with 8 bit RF transmitter. Different 8 bit words are transmitted by buses of different
routes. The buses of same route may have same transmitting code if there are large numbers of
public vehicles to be tracked in large cities. We have used the microcontroller unit which
integrates RFID receiver and GSM unit placed at every bus stop. Every bus stop has 8 bit RF
receiver along with GSM modem installed to send and receive data. Whenever any bus comes
within the range of about 100 feet of the bus stop, the receiver receives the 8 bit word sent by the
7. International Journal of UbiComp (IJU), Vol.3, No.1, January 2012
39
transmitter in a bus, which is kept continuously on. Thus information routing is done using the
microcontroller unit which integrates RFID receiver and GSM unit placed at every bus.
The microcontroller units used at different bus stops are programmed such that they contain GSM
number of the modems placed at further bus stops. The communication between microcontroller
and modem is done using USART (Universal Synchronous Asynchronous Receiver and
Transmitter). The interfacing of RF receiver data with GSM modem is done using microcontroller
unit. The eight bits signal received at receiver are then sent to microcontroller which decodes it
and depending on the bits received sends the AT commands to the GSM modem required for
forwarding vehicle location information to central server and next stops. The algorithm used for
various microcontroller operations is as follows,
Setting the text command for configuring modem:
1. Send “AT+CMGF=1” <CR>
2. Receive the characters from the modem and store in an array and check for “K”.
3. If “K” is present, then text message is OK.
4. Else, reinitialize the modem
5. Delay 1 second.
Enabling for SMS:
1. Send “AT+CNMI=2,1,0,0,0” <CR>
2. Receive the characters from the modem and store in an array and check for “K”. If “K” is
present then modem is initialized completely.
3. Else goto reinitialize the modem.
Sending status to other stops:
1. Send “AT+CMGS=n” <CR> where n is next bus stops phone number.
2. Send the bus identity message along with estimated time for arrival to next ‘n’ stops.
3. Send 0x1A.
Receiving the SMS Number from the modem:
1. Keep on receiving bytes until ‘+ ‘comes.
2. When ‘+’ comes then start storing the bytes in array up to 12th
byte.
3. The 12th
byte is the SMS No.
4. Whenever a SMS is received we receive AT+CMTI: “SM”, 1.
Reading the SMS Received:
1. Send “AT+CMGR=” <CR> to check for any incoming message
8. International Journal of UbiComp (IJU), Vol.3, No.1, January 2012
40
2. Give delay of 1millisecond.
3. Send the SMS Number.
4. Send 0x0D.
5. Send 0x0A.
6. Receive bytes until ‘1’ comes.
7. After getting ‘1’ start storing the received bytes in an array until ” comes.
8. This is the sender’s phone number.
9. Continue receiving until * comes.
10. Start storing the character after * & store in an array until # comes.
11. If the array size is below 25, then it is a valid message
Deleting the SMS :
1. Set “AT+CMGD=”
2. Delay 1 msec.
3. Send SMS number.
4. Send 0x0D.
5. Send 0x0A.
6. Keep on receiving characters from the modem till ‘K’ comes.
7. When ‘K’ is received, SMS is deleted.
‘AT’ commands sent to GSM modem forwards the SMS containing the 8 bit code of the bus and
bus stop id to the next 4 or more bus stops and to central server. Thus, the information about
location of bus is passed to next bus stops. We have designed, implemented and tested the system
in our lab. The system prototype set up and some of its components are shown in Figure 3. To test
the functionality of the system we placed the RF transmitter in a mobile vehicle. While the
vehicle was moving vehicle's current location was reported to the further stops as well as to the
central server. The SMS received by the modems located at different bus-stops is sent to the
microcontroller unit. The microcontroller unit analyzes the received message through GSM
modem and decodes the information being sent in the form of message. Finally, information
about bus arrival is sent to the LED display board connected to microcontroller unit. The LED
display board displays the

Figure 3. RF Receiver and GSM/GPRS modem used for lab testing
message about bus with estimated time of arrival of bus at that bus stop. The LED boards display
the time of arrival of different buses as different messages are sent to it through the
microcontroller unit. Some useful information can also be displayed on the display boards as
message can be also be forwarded from the central server having database of phone numbers
allotted to different SIM placed in the GSM modems. Thus, important information like route
change due to some reasons, can be circulated to the public in different situations.
6. DISCUSSION ON LOW COST SOLUTION
Efforts have been taken to reduce the total cost of the system including devices and services.
Starting from small transport systems to larger transport systems, the devices and services cost
can be made affordable. The different components used are 8 channel Radio frequency
transmitter and receiver, GSM modem, interfacing controller unit and display unit which make
the overall system cost effective. By using SMS for communication, the service cost has been
reduced drastically. Most operators are providing SMS services at very cheap rates. Thus
components and service cost of the system is much lesser than other tracking systems available in
market.
7. SYSTEM TESTING AND RESULTS
System design is verified by testing after integration of all components of the system. The whole
setup consisting of various components like RFID transmitter and receiver, GSM modem along
with controller interface is tested in lab. Debugging serial port of microcontroller was connected
to a PC’s COM port to see the results on HyperTerminal during its operation as shown in the
Figure 4.

Figure 4. Hyperterminal image showing simulation results
The LED/LCD board displays the location of bus with estimated time of arrival of bus at that bus
stop, as shown in Figure 5. The tracking of buses at some server located at a particular place is
easily carried out by having a modem connected to server. The location information of different
buses is updated, as GSM modems located at each bus stop forwards an SMS containing vehicle
location information to this central server. Thus the central server keeps tracks of different buses.
Figure 6 shows the application interface build using Microsoft Visual Basic at the server. It
receives the different messages, thus keeps track of public vehicle's current location. The
application interface receives and analyzes the data received by it and thus tracking of all the
buses can be done at the central server providing more information which can be used for analysis
of traffic in different routes and other information.

8. CONCLUSION
The key feature of this system is its relatively simple mode of communication. The tracking of
different local buses or local train can be done easily. The project involves the use of GSM and
RFID technology which is used to send and receive information for locating any vehicle.
Our proposed system is vulnerable to network congestions as the SMS sent to other locations may
get delayed. Thus, the efficiency of the proposed system depends on the congestion free working
of GSM networks. The use of GSM technology as compared to other existing techniques used for
tracking makes it more cost efficient and innovative. Our system design has an open architecture
that can be easily expanded to other applications. These features make the device completely
suitable for public vehicle tracking applications because:
(i) low cost system opens up a new segment of the market.
(ii) use of GSM technology allows tracking in high density urban areas
This system can be easily extended for central tracking system to keep track of all the public
vehicles. The code size of microcontrollers can be reduced as the vehicle’s location information
routing can be done via central server application. The different queries and efficient route
management can be easily done through central server system. Trends in wireless technology
have resulted in most of the passengers owning mobile phones. We believe that by providing bus-
route and arrival information to passengers’ cell phones in a timely manner, it is possible to
improve the bus occupancy. Thus, this system can be integrated with internet which maintains
the vehicle’s current location database so that people owing mobiles can enter vehicle route
number and bus-stop ID and get the time arrival of respective bus on their mobile. Due to easily
available gadgets like mobile phones, laptops, Personal Digital Assistants (PDAs), passengers
would not have to rely on old manual enquiry terminals. Thus, the proposed system is beneficial
for both passengers and the bus operators.
