Public transport has an important role to play in the
provision of reliable travel in congested conditions as it makes
excellent use of limited road space, carrying many more
passengers than a private car for a given amount of road space.
This paper involves study and analysis of various Bus Priority
Measures in terms of change in delay with respect to normal
intersection for the buses and also for whole traffic flow
(including buses and all other vehicles) with the help of results
of VISSIM simulation software for various volumes of traffic
flow. These measures can be applied to give buses priority to
make them a more attractive alternative to the private vehicles
and reducing road congestion.
Performance Analysis of Continuous Flow Intersection in Mixed Traffic Condition IDES Editor
This document summarizes a study that evaluates the performance of a Continuous Flow Intersection (CFI) using computer simulation under mixed traffic conditions. The study compares the average delays of vehicles at a CFI to those at a Normal Flow Intersection (NFI) for different traffic volumes and proportions of right-turning traffic. The results show that the CFI has lower average delays than the NFI for all traffic scenarios tested, with delays reduced by 30-60% on average. The CFI design provides benefits without requiring additional land and can better utilize existing road infrastructure capacity.

The document discusses concepts for improving feeder services in bus rapid transit systems (BRTS) in Indian cities. It notes that BRTS systems need to be scaled up and down to meet the needs of large and small cities in India. Scaling up involves increasing capacity through design changes like segregated lanes and passing lanes. Scaling down involves concepts like one-way BRTS, elevated BRTS, mini-BRTS, and integrating feeder services. The document emphasizes that Indian cities require affordable and tailored BRTS solutions that can adapt to right-of-way constraints and dispersed land use patterns. It also stresses the importance of pedestrian access and completing local pedestrian networks to key destinations to effectively connect people to BRTS.

This document discusses the impacts of Bus Rapid Transit Systems (BRTS) on cities. It begins with an introduction to BRTS and their benefits like being fast, reliable, and cost-effective. It then reviews literature on BRTS implemented in various Indian cities. The document discusses various impacts of BRTS like reduced travel times, environmental benefits from lower emissions, public health benefits from reduced accidents and air pollution, urban development impacts from increased land values near stations, and economic impacts from job creation. It concludes that BRTS can help meet cities' mobility needs affordably and efficiently while reducing pollution.
When evaluating mass transit options for Indian cities, metro rail systems are given preference over surface systems due to the belief that road-based bus systems cannot cater to the capacity requirement as much as metro systems can. In addition, metro rails are perceived to have higher levels of comfort, speed, and efficiency than bus systems.

The system was implemented to address the city's growing traffic issues, with motor vehicle growth at 9.5% annually and public transportation only accounting for 0.5% of trips. The BRTS includes dedicated bus lanes, bus shelters, and aims to increase the mode share of public transit. Over 6 lakh commuters have used the pilot BRTS project since operations began, with 11 buses running at 4 minute headways and fares from Rs. 5 to 23. Issues faced during implementation included public resistance after other BRTS projects, encroachments, utility shifting,
Bus rapid transit (BRT) systems provide major benefits to cities by offering efficient, reliable public transportation that reduces congestion and pollution. The first successful BRT was implemented in Curitiba, Brazil in the 1970s and served as a model for other cities. A study of 20 BRT case studies from around the world found that BRT systems consume less energy and emit fewer emissions than traditional bus systems or private vehicles. BRT can help contain urban sprawl, promote social inclusion, and spur economic development near stations over the long term. While BRT requires fewer dedicated facilities than other rail systems, it still faces challenges including potential traffic disruptions and requires strong political support to implement high-quality service.
L & T Metro Rail Impact Assessment Study - Stage 3Ramesh Satyam
Pragna Research Consultancy Services, Hyderabad did an Impact Assessment Study of Hyderabad Metro Rail Project for L&T Metro Rail. 4 Reports on the 4 different Stages with numerous errors and repetitions done using cut, copy and paste of content across reports were delivered to L & T Metro Rail. The junk contained in the Reports had to be processed to enable reuse and recycle of content for the Presentations.
A staffer in L&T Metro Rail was given my telephone number for contact by a lady from Pragna for assistance in converting the Reports into Presentations. The staffer said that she couldn’t do it herself as she was busy with personal matters and had to seek help on personal request and compensate for it out of her salary. The staffer grossly underestimated the costs, labor and time involved in the work, for reasons best known to her, which was far beyond her ability to pay for it. She and the lady from Pragna insist that L&T Metro Rail and Pragna have nothing to do with this work and this was expected to be done on a personal capacity for a payment that is less than 1/10th of the cost involved to do it.
The Report on Stage 3 was converted into a Presentation and sent to the staffer. Since either of the organizations involved in the creation of these Reports say they have nothing to do with it, the staffer has no ability to pay a realistic price for the conversion of Reports into Presentations and given the prevalent poverty (not necessarily in the material sense) of these organizations and staff working with them, I decide to leave this presentation with them as a donation.
To discourage full or partial use of the contents without acknowledgement of source by these organizations and their staff, as well as to get a bit of personal mileage as return for this unpaid free effort (can we call it voluntary?) and provide some insights on what is perceived to be happening by people of Hyderabad on the Metro Rail Project, the Presentation on Stage 3 (Begumpet to Shilparamam) is available online for those who may be interested in it.
World Class Bus Rapid Transit System (BRTS) for BangaloreKiran Shaw
This document proposes a world-class bus rapid transit system (BRTS) along the 30 km Outer Ring Road corridor in Bangalore between Hebbal and Silk Board. The corridor experiences high traffic congestion with average bus speeds of 10-12 km/hr. A BRTS is recommended to provide a mass transit solution with a capacity of 12,000-30,000 passengers per hour per direction. The proposed BRTS design includes segregated bus lanes, passing lanes, and stations every 700-800 meters. The total implementation cost is estimated to be Rs. 1,024.80 crore. A BRTS can be built more quickly and at lower cost than an alternative metro rail system for this corridor's passenger demand

This document proposes two bus lane routes in Bangalore to help address traffic congestion issues. Route 1 runs 28 km from Domlur to Electronic City along major roads. Route 2 runs 18 km in a loop from Shantinagar Bus Station through areas like Richmond Town and Indiranagar, connecting to Route 1. The routes are intended to provide faster, more reliable bus transport as an alternative to private vehicles and feed into existing and planned metro lines. Underpasses are proposed at certain intersections to allow bus-only passage.
The document discusses sustainable transportation and provides details about Bus Rapid Transit (BRT) systems in India. It describes the key features of successful BRT systems, using the examples of the Ahmedabad and Pimpri-Chinchwad BRT networks. The Ahmedabad BRT was the first in India and has been recognized as a successful project, carrying over 35,000 daily passengers in a sustainable way by limiting emissions and improving pedestrian infrastructure. Essential features for effective BRT identified include adequate road width, limited intersections, exclusive bus bays, and proximity of stations to pedestrian crossings and trip generators.
Due to rapid unplanned development, versatile land use, rapid population
growth, poor public transport system and increase of private car users, traffic
problems are worsening day by day. The only mass transit is bus which is
insufficient in terms of safety, capacity, comfort, and convenience. Considering
the worsening congestion, it is high time to develop effective mass transit
system such as Bus Rapid Transit (BRT) as a means for achieving sustainable
urban transport in the city
This document discusses the introduction of bus rapid transit (BRT) systems in Asian developing cities. It outlines key conditions for enhancing BRT development, such as integrating land use and transportation planning and providing exclusive busways.

Mass rapid transit, also referred to as public transit, is a passenger transportation service, usually local in scope, that is available to any person who pays a prescribed fare.
It usually operates on specific fixed tracks or with separated and exclusive use of potential common track, according to established schedules along designated routes or lines with specific stops.
It is designed to move large numbers of people at one time.

Theme 6 BRT vs. LRT moving beyond emotional biasBRTCoE
This document summarizes a presentation on critical elements of successful bus rapid transit (BRT) systems and gaining public support for BRT over light rail transit (LRT) systems. The presentation discusses existing evidence on ridership drivers for BRT systems and potential service and design barriers that influence public perceptions of BRT versus LRT. It also describes a best-worst choice experiment conducted with residents of six Australian cities to measure perceptions of statements related to BRT and LRT services and identify key factors influencing support for different public transit modes. The results showed many similar voting preferences between public transit users and non-users, but also some differences in how much certain attributes were valued.
The document discusses Bus Rapid Transit Systems (BRTS) as presented by Chirag Bhasin of Punjab Engineering College. BRTS is described as a high-quality transit system based on buses that can transport up to 20,000 passengers per hour in a single direction using dedicated bus lanes similar to metro rail systems. BRTS provides advantages over other transit systems such as lower construction costs since it can convert existing roads. Key features of BRTS discussed include separated bus-only lanes, off-board fare collection, and platform-level boarding to reduce delays. Various levels of BRTS implementation are also outlined.
Mass transit system refers to public shared transportation, such as trains, buses, ferries etc that can commute a larger number of passengers from origin to destination on a no-reserved basis and in lesser time. It can also be termed as Public Transport.

Power System State Estimation - A ReviewIDES Editor
This document provides a review of power system state estimation techniques. It discusses both static and dynamic state estimation algorithms. For static state estimation, it covers weighted least squares, decoupled, and robust estimation methods. Weighted least squares is commonly used but can have numerical instability issues. Decoupled state estimation approximates the gain matrix for faster computation. Robust estimation uses M-estimators and other techniques to handle outliers and bad data. Dynamic state estimation applies Kalman filtering, leapfrog algorithms, and other methods to continuously monitor system states over time.
Artificial Intelligence Technique based Reactive Power Planning Incorporating...IDES Editor
This document summarizes a research paper that proposes using artificial intelligence techniques and FACTS controllers for reactive power planning in real-time power transmission systems. The paper formulates the reactive power planning problem and incorporates flexible AC transmission system (FACTS) devices like static VAR compensators (SVC), thyristor controlled series capacitors (TCSC), and unified power flow controllers (UPFC). Evolutionary algorithms like evolutionary programming (EP) and differential evolution (DE) are applied to find the optimal locations and settings of the FACTS controllers to minimize losses and costs. Simulation results on IEEE 30-bus and 72-bus Indian test systems show that UPFC performs best in reducing losses compared to SVC and TCSC.
Design and Performance Analysis of Genetic based PID-PSS with SVC in a Multi-...IDES Editor
Damping of power system oscillations with the help
of proposed optimal Proportional Integral Derivative Power
System Stabilizer (PID-PSS) and Static Var Compensator
(SVC)-based controllers are thoroughly investigated in this
paper. This study presents robust tuning of PID-PSS and
SVC-based controllers using Genetic Algorithms (GA) in
multi machine power systems by considering detailed model
of the generators (model 1.1). The effectiveness of FACTSbased
controllers in general and SVC-based controller in
particular depends upon their proper location. Modal
controllability and observability are used to locate SVC–based
controller. The performance of the proposed controllers is
compared with conventional lead-lag power system stabilizer
(CPSS) and demonstrated on 10 machines, 39 bus New England
test system. Simulation studies show that the proposed genetic
based PID-PSS with SVC based controller provides better
performance.
Optimal Placement of DG for Loss Reduction and Voltage Sag Mitigation in Radi...IDES Editor
This paper presents the need to operate the power
system economically and with optimum levels of voltages has
further led to an increase in interest in Distributed
Generation. In order to reduce the power losses and to improve
the voltage in the distribution system, distributed generators
(DGs) are connected to load bus. To reduce the total power
losses in the system, the most important process is to identify
the proper location for fixing and sizing of DGs. It presents a
new methodology using a new population based meta heuristic
approach namely Artificial Bee Colony algorithm(ABC) for
the placement of Distributed Generators(DG) in the radial
distribution systems to reduce the real power losses and to
improve the voltage profile, voltage sag mitigation. The power
loss reduction is important factor for utility companies because
it is directly proportional to the company benefits in a
competitive electricity market, while reaching the better power
quality standards is too important as it has vital effect on
customer orientation. In this paper an ABC algorithm is
developed to gain these goals all together. In order to evaluate
sag mitigation capability of the proposed algorithm, voltage
in voltage sensitive buses is investigated. An existing 20KV
network has been chosen as test network and results are
compared with the proposed method in the radial distribution
system.
Line Losses in the 14-Bus Power System Network using UPFCIDES Editor
Controlling power flow in modern power systems
can be made more flexible by the use of recent developments
in power electronic and computing control technology. The
Unified Power Flow Controller (UPFC) is a Flexible AC
transmission system (FACTS) device that can control all the
three system variables namely line reactance, magnitude and
phase angle difference of voltage across the line. The UPFC
provides a promising means to control power flow in modern
power systems. Essentially the performance depends on proper
control setting achievable through a power flow analysis
program. This paper presents a reliable method to meet the
requirements by developing a Newton-Raphson based load
flow calculation through which control settings of UPFC can
be determined for the pre-specified power flow between the
lines. The proposed method keeps Newton-Raphson Load Flow
(NRLF) algorithm intact and needs (little modification in the
Jacobian matrix). A MATLAB program has been developed to
calculate the control settings of UPFC and the power flow
between the lines after the load flow is converged. Case studies
have been performed on IEEE 5-bus system and 14-bus system
to show that the proposed method is effective. These studies
indicate that the method maintains the basic NRLF properties
such as fast computational speed, high degree of accuracy and
good convergence rate.
Study of Structural Behaviour of Gravity Dam with Various Features of Gallery...IDES Editor
The size and shape of opening in dam causes the
stress concentration, it also causes the stress variation in the
rest of the dam cross section. The gravity method of the analysis
does not consider the size of opening and the elastic property
of dam material. Thus the objective of study is comprises of
the Finite Element Method which considers the size of
opening, elastic property of material, and stress distribution
because of geometric discontinuity in cross section of dam.
Stress concentration inside the dam increases with the opening
in dam which results in the failure of dam. Hence it is
necessary to analyses large opening inside the dam. By making
the percentage area of opening constant and varying size and
shape of opening the analysis is carried out. For this purpose
a section of Koyna Dam is considered. Dam is defined as a
plane strain element in FEM, based on geometry and loading
condition. Thus this available information specified our path
of approach to carry out 2D plane strain analysis. The results
obtained are then compared mutually to get most efficient
way of providing large opening in the gravity dam.
Assessing Uncertainty of Pushover Analysis to Geometric ModelingIDES Editor
Pushover Analysis a popular tool for seismic
performance evaluation of existing and new structures and is
nonlinear Static procedure where in monotonically increasing
loads are applied to the structure till the structure is unable
to resist the further load .During the analysis, whatever the
strength of concrete and steel is adopted for analysis of
structure may not be the same when real structure is
constructed and the pushover analysis results are very sensitive
to material model adopted, geometric model adopted, location
of plastic hinges and in general to procedure followed by the
analyzer. In this paper attempt has been made to assess
uncertainty in pushover analysis results by considering user
defined hinges and frame modeled as bare frame and frame
with slab modeled as rigid diaphragm and results compared
with experimental observations. Uncertain parameters
considered includes the strength of concrete, strength of steel
and cover to the reinforcement which are randomly generated
and incorporated into the analysis. The results are then
compared with experimental observations.

Selfish Node Isolation & Incentivation using Progressive ThresholdsIDES Editor
The problems associated with selfish nodes in
MANET are addressed by a collaborative watchdog approach
which reduces the detection time for selfish nodes thereby
improves the performance and accuracy of watchdogs[1]. In
the related works they make use of credit based systems, reputation
based mechanisms, pathrater and watchdog mechanism
to detect such selfish nodes. In this paper we follow an approach
of collaborative watchdog which reduces the detection
time for selfish nodes and also involves the removal of such
selfish nodes based on some progressively assessed thresholds.
The threshold gives the nodes a chance to stop misbehaving
before it is permanently deleted from the network.
The node passes through several isolation processes before it
is permanently removed. Another version of AODV protocol
is used here which allows the simulation of selfish nodes in
NS2 by adding or modifying log files in the protocol.
Various OSI Layer Attacks and Countermeasure to Enhance the Performance of WS...IDES Editor
Wireless sensor networks are networks having non
wired infrastructure and dynamic topology. In OSI model each
layer is prone to various attacks, which halts the performance
of a network .In this paper several attacks on four layers of
OSI model are discussed and security mechanism is described
to prevent attack in network layer i.e wormhole attack. In
Wormhole attack two or more malicious nodes makes a covert
channel which attracts the traffic towards itself by depicting a
low latency link and then start dropping and replaying packets
in the multi-path route. This paper proposes promiscuous mode
method to detect and isolate the malicious node during
wormhole attack by using Ad-hoc on demand distance vector
routing protocol (AODV) with omnidirectional antenna. The
methodology implemented notifies that the nodes which are
not participating in multi-path routing generates an alarm
message during delay and then detects and isolate the
malicious node from network. We also notice that not only
the same kind of attacks but also the same kind of
countermeasures can appear in multiple layer. For example,
misbehavior detection techniques can be applied to almost all
the layers we discussed.
Responsive Parameter based an AntiWorm Approach to Prevent Wormhole Attack in...IDES Editor
The recent advancements in the wireless technology
and their wide-spread deployment have made remarkable
enhancements in efficiency in the corporate and industrial
and Military sectors The increasing popularity and usage of
wireless technology is creating a need for more secure wireless
Ad hoc networks. This paper aims researched and developed
a new protocol that prevents wormhole attacks on a ad hoc
network. A few existing protocols detect wormhole attacks but
they require highly specialized equipment not found on most
wireless devices. This paper aims to develop a defense against
wormhole attacks as an Anti-worm protocol which is based on
responsive parameters, that does not require as a significant
amount of specialized equipment, trick clock synchronization,
no GPS dependencies.
Cloud Security and Data Integrity with Client Accountability FrameworkIDES Editor
This document summarizes a proposed cloud security and data integrity framework that provides client accountability. The framework aims to address issues like lack of user control over cloud data, need for data transparency and tracking, and ensuring data integrity. It proposes using JAR (Java Archive) files for data sharing due to benefits like portability. The framework incorporates client-side verification using MD5 hashing, digital signature-based authentication of JAR files, and use of HMAC to ensure data integrity. It also uses password-based encryption of log files to keep them tamper-proof. The framework is intended to provide both accountability and security for data sharing in cloud environments.
Genetic Algorithm based Layered Detection and Defense of HTTP BotnetIDES Editor
A System state in HTTP botnet uses HTTP protocol
for the creation of chain of Botnets thereby compromising
other systems. By using HTTP protocol and port number 80,
attacks can not only be hidden but also pass through the
firewall without being detected. The DPR based detection
leads to better analysis of botnet attacks [3]. However, it
provides only probabilistic detection of the attacker and also
time consuming and error prone. This paper proposes a Genetic
algorithm based layered approach for detecting as well as
preventing botnet attacks. The paper reviews p2p firewall
implementation which forms the basis of filtering.
Performance evaluation is done based on precision, F-value
and probability. Layered approach reduces the computation
and overall time requirement [7]. Genetic algorithm promises
a low false positive rate.
Enhancing Data Storage Security in Cloud Computing Through SteganographyIDES Editor
This document summarizes a research paper that proposes a method for enhancing data security in cloud computing through steganography. The method hides user data in digital images stored on cloud servers. When data needs to be accessed, it is extracted from the images. The document outlines the cloud architecture and security issues addressed. It then describes the proposed system architecture, security model, and data storage and retrieval process. Data is partitioned and hidden in multiple images to improve security. The goal is to prevent unauthorized access to user data stored on cloud servers.
The main tasks of a Wireless Sensor Network
(WSN) are data collection from its nodes and communication
of this data to the base station (BS). The protocols used for
communication among the WSN nodes and between the WSN
and the BS, must consider the resource constraints of nodes,
battery energy, computational capabilities and memory. The
WSN applications involve unattended operation of the network
over an extended period of time. In order to extend the lifetime
of a WSN, efficient routing protocols need to be adopted. The
proposed low power routing protocol based on tree-based
network structure reliably forwards the measured data towards
the BS using TDMA. An energy consumption analysis of the
WSN making use of this protocol is also carried out. It is
found that the network is energy efficient with an average
duty cycle of 0:7% for the WSN nodes. The OmNET++
simulation platform along with MiXiM framework is made
use of.
Permutation of Pixels within the Shares of Visual Cryptography using KBRP for...IDES Editor
The security of authentication of internet based
co-banking services should not be susceptible to high risks.
The passwords are highly vulnerable to virus attacks due to
the lack of high end embedding of security methods. In order
for the passwords to be more secure, people are generally
compelled to select jumbled up character based passwords
which are not only less memorable but are also equally prone
to insecurity. Multiple use of distributed shares has been
studied to solve the problem of authentication by algorithms
based on thresholding of pixels in image processing and visual
cryptography concepts where the subset of shares is considered
for the recovery of the original image for authentication using
correlation function[1][2].The main disadvantage in the above
study is the plain storage of shares and also one of the shares
is being supplied to the customer, which will lead to the
possibility of misuse by a third party. This paper proposes a
technique for scrambling of pixels by key based random
permutation (KBRP) within the shares before the
authentication has been attempted. Total number of shares to
be created is dependent on the multiplicity of ownership of
the account. By this method the problem of uncertainty among
the customers with regard to security, storage, retrieval of
holding of half of the shares is minimized.
This paper presents a trifocal Rotman Lens Design
approach. The effects of focal ratio and element spacing on
the performance of Rotman Lens are described. A three beam
prototype feeding 4 element antenna array working in L-band
has been simulated using RLD v1.7 software. Simulated
results show that the simulated lens has a return loss of –
12.4dB at 1.8GHz. Beam to array port phase error variation
with change in the focal ratio and element spacing has also
been investigated.
Band Clustering for the Lossless Compression of AVIRIS Hyperspectral ImagesIDES Editor
Hyperspectral images can be efficiently compressed
through a linear predictive model, as for example the one
used in the SLSQ algorithm. In this paper we exploit this
predictive model on the AVIRIS images by individuating,
through an off-line approach, a common subset of bands, which
are not spectrally related with any other bands. These bands
are not useful as prediction reference for the SLSQ 3-D
predictive model and we need to encode them via other
prediction strategies which consider only spatial correlation.
We have obtained this subset by clustering the AVIRIS bands
via the clustering by compression approach. The main result
of this paper is the list of the bands, not related with the
others, for AVIRIS images. The clustering trees obtained for
AVIRIS and the relationship among bands they depict is also
an interesting starting point for future research.
Microelectronic Circuit Analogous to Hydrogen Bonding Network in Active Site ...IDES Editor
A microelectronic circuit of block-elements
functionally analogous to two hydrogen bonding networks is
investigated. The hydrogen bonding networks are extracted
from â-lactamase protein and are formed in its active site.
Each hydrogen bond of the network is described in equivalent
electrical circuit by three or four-terminal block-element.
Each block-element is coded in Matlab. Static and dynamic
analyses are performed. The resultant microelectronic circuit
analogous to the hydrogen bonding network operates as
current mirror, sine pulse source, triangular pulse source as
well as signal modulator.
Texture Unit based Monocular Real-world Scene Classification using SOM and KN...IDES Editor
In this paper a method is proposed to discriminate
real world scenes in to natural and manmade scenes of similar
depth. Global-roughness of a scene image varies as a function
of image-depth. Increase in image depth leads to increase in
roughness in manmade scenes; on the contrary natural scenes
exhibit smooth behavior at higher image depth. This particular
arrangement of pixels in scene structure can be well explained
by local texture information in a pixel and its neighborhood.
Our proposed method analyses local texture information of a
scene image using texture unit matrix. For final classification
we have used both supervised and unsupervised learning using
K-Nearest Neighbor classifier (KNN) and Self Organizing
Map (SOM) respectively. This technique is useful for online
classification due to very less computational complexity.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
