This document summarizes research conducted to develop a system to improve traffic flows on Dutch highways. The system aims to reduce traffic jams by 30-40% by advising drivers on speeds to maintain through a smartphone app. The app collects GPS and speed data from cars and downloads advised speed profiles from a backend server based on real-time traffic conditions. The system architecture involves communication between the app, onboard car units using USB, and roadside units using WiFi for data collection and dissemination of advised speeds to improve stable traffic flows and reduce braking.

Improvements in information technology related technologies are encouraging and enabling greater use of public transportation and they are enabling new forms of transportation systems that have lower carbon emissions and use less resources. Improvements in information-related technologies such as mobile phones and GPS encourage greater use of public buses, bicycle sharing systems, and trains. These same improvements are making autonomous vehicles economically feasible and roads dedicated to them. Roads dedicated to them can reduce congestion, increase fuel efficiency, and reduce accidents and costs related to them. In combination with public transportation, autonomous vehicles can reduce the need for private vehicles and thus parking spaces. Similar types of improvements in power electronics are reducing the cost and improving the performance of charging stations and thus enable more rapid recharging with a denser number of charging stations. This rapid and more frequent recharging can overcome the existing bottleneck of lower battery storage densities and slow improvements in these storage densities. Overall, improvements in information technology are making possible new forms of sustainable systems that have a much higher chance of becoming economically feasible than more commonly discussed solutions such as hybrid vehicles and wind turbines.

In this paper, we propose a method for detecting the positions of pedestrians by cooperation of multiple cars with directional antennas to support drivers for pedestrian safety. In the method, each pedestrian carries a device which periodically transmits a beacon with a unique ID, and each car passing near the pedestrian receives the beacon by a directional antenna and measures the distance and the angle of arrival.
We assume the distribution of the measurement errors to be a normal distribution, and the system calculates the existence probabilities of each pedestrian at each point. By exchanging information of the probabilities between cars, the area with high existence probability is narrowed down. In this paper, we first describe the situations where detecting positions of pedestrians greatly contribute to pedestrian safety, and then we describe the probability model used in our method, the method for calculating existence probabilities from information from multiple cars, and the protocol for exchanging the probability information between cars. We evaluated our method on QualNet simulator, and confirmed that the positions can be detected accurately enough for practical uses.

Abstract:
Much attention has been attracted to the research of cooperative automatic driving that focuses on safety and efficiency by sharing the data obtained from sensor information of a vehicle. In addition, dynamic maps, a common information and communication platform for the integrated management of shared sensor information, are under consideration. A vehicle always sends data to a server that manages the dynamic map, and the server runs applications for driving support and control on the basis of the data, so fast information processing is required. However, congestion is a concern when data is continuously sent from vehicles to the server at high transmission intervals and when many vehicles are managed by dynamic maps on the server. In addition, the data transmission interval from the vehicle required by the road characteristics differs in actual traffic environments. Therefore, congestion can be alleviated by adjusting the transmission interval of data from the vehicle in consideration of road characteristics. In this paper, a platform for a dynamic map consisting of a server and a vehicle is constructed. We have also implemented a priority processing function that sets the priority for each section of a lane, and adjusts the transmission interval on the basis of the characteristics of the road around the vehicle.

Internet for vanet network communications fleetnetIJCNCJournal
Now in the world, the exchange of information between vehicles in the roads without any fixed infrastructure is enabled thanks to the novel technology of the Vehicular adhoc networks called (VANETs).The accidents and congestions warning, Internet access e.g. via gateways along the road are the main applications of these networks related to the safety and comfort applications. A high requirement on the routing protocols is introduced in these complexed VANETs networks In order to implement a reference intelligent transportation system and contribute to the standardization of vehicle to vehicle communication or vehicle to infrastructure, in Europe, several projects are held and different partners are joined from the industry, governmental agencies and academia.This paper explains the main progress and purposes of the standardization process and research initiatives of FleetNet project. These solutions will present in the future a common worldwide VANET platform integrating several services of inter-vehicles communications.
Cooperative systems offer a universal way for roadside equipment to communicate with vehicles. It provides open connectivity, as promoted by the European Commission. And it also allows multiple applications, to run side by side.
Today, vehicles are emerged with new technologies and deployed with numbers of software applications. Checking
reliability of these software applications is very challenging. The applications can be updated, diagnosed and tested remotely on
road which makes the job of vehicle user easy and convenient. For vehicle communication, Vehicular Ah-hoc Networks
(VANET) is used which is application of Ad-hoc Network. This paper gives brief overview about VANETS and cloud
computing and also discusses the wide research work going on this domain.
Mobile applications are software applications
which are designed to run on mobile smart phones, &
tablets, and other mobile electronic devices, during this
generation of rapid technological advances, these
applications became one altogether the predominant tools
we use daily both in our personal furthermore as
professional lives
RELIABLE SOFTWARE FRAMEWORK FOR VEHICULAR SAFETY APPLICATIONS ON CLOUDIJCI JOURNAL
Vehicular Ad-hoc Networks (VANET’S) have become viable and valuable for their wide variety of novel
applications to improve driver’s experience. The topology of network is highly time varying due to high
mobility of vehicular nodes. This makes challenging to detect and diagnose errors in software
applications used in the vehicles. Software reliability in vehicles is critical factor and significant
challenge to be met. Misbehaving and faulty software applications in vehicle have to be detected and
diagnosed from disrupting operation as it is hard to address in life critical vehicular network
environment. The work proposes an advanced diagnostics system to be loaded in Road Side Units (RSU’s)
so that operating software is periodically transmits the codes generated by the vehicle configured with
OBD to the RSU for test. The software is diagnosed at the RSU accessing the data from cloud servers for
reliability. Later, a fixed patch is transmitted back to the vehicle via RSU’s. The result in this paper shows
the analysis of different temperature variables used in vehicles and are efficiently measured.
Master thesis on Vehicular Ad hoc Networks (VANET)Prof Ansari
The increasing demand for wireless devices and wireless communication tends to research on self-organizing, self-healing networks without the interference of any pre-established or centralized infrastructure/authority [2]. The networks with the absence of any pre-established or centralized authority are known as Ad hoc networks [4]. Ad hoc Networks are the kind of wireless networks that uses multi-hop radio relay.There are many comparative studies and surveys that compare various ad hoc routing in VANET environment. The simulations performed in these comparative studies are very basic do not incorporate with a large number of nodes in real Vehicular Ad hoc Network environment. The main aim of our dissertation work is to firstly investigate the reactive and proactive routeing protocols than examine the performance of selected reactive routing protocols i.e. Destination Sequence Distance Vector Routing (DSDV), Ad hoc On-Demand Distance Vector (AODV), Optimized Link State Routing (OLSR) and Dynamic Source Routing (DSR)by taking three performance metrics like network load, throughput and end-to-end delay with varying number of mobile nodes or vehicle node densityOPNET: Optimized Network Engineering Tool (OPNET) is a commercial network simulator environment used for simulations of both wired and wireless networks [20]. Several different OPNET versions have been released over the last few years; the latest version of OPNET is the OPNET 16.0. At present OPNET is licensed under Riverbed technologies. It allows the user to design and study the network communication devices, protocols, individual applications and also simulate the performance of routing protocol. It supports many wireless technologies and standards such as, IEEE 802.11, IEEE 802.15.1, IEEE 802.16, IEEE 802.20 and satellite networks. OPNET IT Guru Academic Edition is available for free to the academic research and teaching community.
This thesis presents a new dynamic and adaptive G-AODV routing protocol for VANETs inspired by the genetic algorithm in combination with network delay analysis. Genetic Algorithms have been thoroughly investigated in the past for problems such as the Travelling Salesman problem and even the routing problem in communication networks.

In this paper, we propose a method for cars to autonomously and cooperatively collect traffic jam statistics to estimate arrival time to destination for each car using inter-vehicle communication. In the method, the target geographical region is divided into areas, and each car measures time to pass through each area. Traffic information is collected by exchanging information between cars using inter-vehicle communication. In order to improve accuracy of estimation, we introduce several mechanisms to avoid same data to be repeatedly counted. Since wireless bandwidth usable for exchanging statistics information is limited, the proposed method includes a mechanism to categorize data, and send important data prior to other data. In order to evaluate effectiveness of the proposed method, we implemented the method on a traffic simulator NETSTREAM developed by Toyota Central R&D Labs, conducted some experiments and confirmed that the method achieves practical performance in sharing traffic jam information using inter-vehicle communication.

VANET or Vehicular Ad-Hoc Network is a special type of MANET or Mobile Ad-Hoc Network that is
designed specifically for communications between vehicles or V2V and vehicles to infrastructure or V2I. There
is a lot of studies and research that has been dedicated to study this technology due to its importance and
necessity in our life. The fact that each and every module presented must be tested thoroughly before putting it
into action, as there will be severe consequences in case of a system malfunction especially if it's a vehicular
design problem. However, seeing VANETS coming into reality becomes very close with the advancement of
IEEE 802.11p standard that is being dedicated to the DSRC or dedicated short range communication [1]. This
paper will discuss this technology emphasizing some of its applications, current limitations and future challenges

1. Abstract — 30 to 40% of traffic jams are happening on
highways in the Netherlands due to sudden braking and
changing speeds [1]. These root causes are preventable if cars
are driven maintaining a stable speed with little brakes. In
order to drive without brakes, knowing in advance about traffic
conditions up ahead will help eliminate braking. In the other
words, you get notifications on decreasing or increasing your
speed by an internet connected application (app). The app
sends your current GPS coordinate [6] and speed to the server
and downloads the data on how the traffic around you behaves.
On that basis, the app continuously gives you speed advice for
your car. The system ensures that you can anticipate faster in
traffic and thus, drive more evenly. This work is a summary of
the research carried on for developing the system to improve
traffic flows on Dutch highways.
Keywords — on-board unit, speed profile, wifi-p, roadside unit,
roadside LAN, GPS, speed
I. INTRODUCTION
VAST of cars are raising up along with the development
of the population of a country. Although the Netherlands
is one of the smallest European country [2], the number of cars
per family is as many as the number of motorbikes per family
in Vietnam. The people often travel to work by car with a long
distance of more than 100 kilometers, which is considered very
normal in the Netherlands [3].
As a result, highway traffic jams are happening during peak
hours. According to the statistics of the research of the Dutch
Ministry of Infrastructure and Environment [1], traffic jams can
be reduced 30 to 40% if the chauffeurs brake less and change
driving lanes not regularly.
To prevent those actions, a research was carried out to develop
a system to give an optimal speed to the chauffeurs driving on
the roads through a smartphone. For achieving this, we first
need to get the current GPS coordinate [6], driving speed,
driving acceleration, previous brake moments, and driving
lanes of the cars. Then, the data will be gathered on the server,
called Back-office, analyzed and calculated in real-time to
provide back to the cars with an advised speed. The system
overview is given in Figure 1, which contains a number of
different communication protocols to support the data exchange

of Sioux companies in the Netherlands and Vietnam; and was supported by the

between the car and the Back-office server side:
App to Back-office via 3G
App to on-board car unit via USB
On-board car unit to roadside via Wifi-P
Figure 1 - System Architecture
These protocols will be described in the following chapters.
II. APP TO BACK OFFICE VIA 3G
The app retrieves the current coordinate and speed from the
integrated GPS module in the phone. Per predefined interval,
the app will send these information together with the maximum
speed of the car (based on the configuration by the user) toward
the back-office server, which is session-less [9]; while the
session is on the phone.
Figure 2 - A speed profile
A speed profile, which contains minimum and maximum speed
of the driving lane and the advised speed, is returned from the
server. Figure 2 shows an example of providing different speeds
on different positions of the vehicle on the road.

2. III. APP TO ON-BOARD CAR UNIT VIA USB
Onboard Unit (OBU) is a Cohda Mk4 device [5]. The Cohda
Mk4 is conceptually similar to the Raspberry Pi [10]. It is a
single-board computer (ARM processor, 512 DDR RAM,
Linux, a CAN bus connector [11], Wifi-P radio [8], GPS
receiver) designed for automotive applications. The device is
mounted inside the car, which is called 'onboard unit' (OBU).
OBU facilitates more data to the phone than just GPS
coordinates and speed; in which we can see the supplied data in
Figure 3:
Figure 3 - Data outputs from Onboard Unit
The OBU not only addresses technical limitations of GPS
coverage and robustness of the integrated GPS module [12]
inside the phone but also provides other useful data such as:
lighting conditions, previous brake moments, accelerations and
driving lanes. OBU provides data to the phone via USB
connection. The app will also send these information toward the
server. This improves the calculations at the server side of not
only returning advised speed, but also advised driving lane and
the statistics of brakes on the current trip.
IV. ONBOARD CAR UNIT TO ROADSIDE VIA WIFI-P
In highway traffic scenarios, when a vehicle meets an
emergency event or behaves abnormally when confronted by
unexpected maneuver or major mechanical failure, it generates
emergency collision warning message and broadcasts it to all
vehicles within its platoon.
There are two main types of communicating message: vehicle
to vehicle (V2V) and vehicle to roadside (V2R). V2R is chosen
to apply on the high way in the Netherlands.
Roadside Unit (RSU) [7] is a computing device located on the
roadside that provides connectivity support to passing vehicles.
They are set up every certain distance on the high road in
Holland. They help all the vehicles in their range communicate
with each other via Wifi-P [8]. The mechanism is illustrated in
Figure 4 below:
Figure 4 - Roadside LAN communication
With this add-on communication, in case there is a problem
with 3G or GPRS coverage on the roads or GPS technical issue,
this communication can support to transfer the data to the
server. However, implementing roadside protocol on the roads
involves a lot of costs and effort in installations, this is therefore
only applied at high traffic roads with weak 3G signal.
V. BACK-OFFICE SERVER FOR BIG DATA
At the Back-office server, there are huge volume of data
received from different sources: the Apps and roadsides. A
multi-distributed system [13] was developed, which is called
Big Data Analyzer, contains a lot of mathematic models,
routing algorithms and real-time analytic models. Formally, it
is known as a high quality decision maker running 24/7 with a
very high reliable up-time to deliver optimal advised speeds and
driving lanes on the roads for the chauffeurs based on a lot of
real case studies on traffic jams in the Netherlands like Figure
5.
Figure 5 - Case studies on traffic jams
VI. CONCLUSIONS
Around the world, we are working on ways to make traffic
faster, safer, more comfortable and sustainable. The
Netherlands is a leader in the development of traffic
communication techniques, in which vehicles communicate
with each other and work together to reduce congestion,
increase road capacity, improve comfort for the driver and
increase the safety. The goal of the project scope is to improve
traffic flow on the highways in the Netherlands. But the
ambitions go further: with the success of the project, the
3. partners of the project want to expand the services of the
projects to support other European countries.
VII. FUTURE WORKS
The results achieved so far have been promising after finishing
the testing phase in the Netherlands for a half year. However, a
number of components in the system still can be improved. The
app was first developed for Android and it can be ported on
other platforms such as: iOS and Windows phone so it brings
more flexible for choices for the users. The advantage of the
current app development facilitates the porting process as an
easy because Xamarin [4] technology was chosen. The Big
Data Analyzer was developed with a lot of effort and attention
to calculate the data in real-time situation. Based on the testing
results, there were still unexpected cases happening. It requires
more fine-tuning and optimizing the algorithms to improve the
robustness of the system.
