In this paper, the researchers have made an attempt to address the problem of traffic network congestion to speed up the disaster response activity during a disaster. A dynamic environment is made up of static and moving obstacles. Each moving vehicle acts as a dynamic obstacle for other moving vehicle. There by increasing the network congestion. It is shown that the game theoretic model effect...

This paper aims to investigate a new and intricate behavior of immediate follower during the lane change of leader vehicle. Accordingly, the mentioned situation is a transient state in car following behavior during which the follower vehicle considerably deviates from conventional car following models for a limited time, which is a complex state including lateral and longitudinal movement simul...

The development of an advanced safety vehicle (ASV) has primary importance for automobile manufactures and customers. The safety measures of modern vehicles involve active and passive safety. Active safety devices provide the driver with warning signals or aaect the vehicle's motion in order to prevent an accident. Passive safety devices help to avoid injuires and post-collision hazards if an a...

More than 23% of annual vehicle accidents are rear-end collisions, which provides an important test-case for enhanced collision avoidance approaches based on v2v wireless communications. In this work, we propose and study the impact of a 802.11 based multi-hop MAC protocol that propagates an emergency warning message (EWM) down a platoon of cars on a highway. The design objective is to ensure r...

Modern automotive Cyber-Physical Systems (CPSs) are increasingly adopting wireless communications for IntraVehicular, Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) protocols as a promising solution for challenges such as the wire harnessing problem, collision detection, and collision avoidance. Regrettably, this new trend results in new security vulnerabilities that can put the s...

In the event of a collision between a traveling, high speed train and a vehicle, the scale of human fatality and property damage can increase substantially if the train derails from its track after impact. Hence, it is important to identify the conditions and factors that may potentially lead to derailment in the event of a train-vehicle collision incident at a highway rail grade crossing. This...

rfid system is a wireless technology that can transfer data between tags and readers via radio frequency. in an rfid network, readers are located close to each other to obtain optimal connectivity and sufficient coverage. in such an environment, which is called dense reader environment (dre).different types of collisions such as reader-to-reader and reader-to-tag ones, often lead to serious pro...

The mitigation of the risks passenger injuries when a vehicle is involved in collision with street pole shielded layer tire-derived material (TDM) was assessed. This can effectively absorb fraction total energy from speeding vehicle. Since such tests are expensive to conduct experimentally, study relies on using Abaqus/Explicit FEA solver accurately calculate non-linear nature this scenario. Tw...

Collision warning/collision avoidance (CW/CA) systems target a major crash type and their development is a major thrust of the Intelligent Vehicle Initiative. They are a natural extension of adaptive cruise control systems already available on many car models. Many CW/CA algorithms have recently been proposed but the existing literature mainly focuses on algorithm development. Evaluations of th...

This paper presents the application of Buckingham’s π theorem to scale the powertrain of a High Mobility Multipurpose Wheeled Vehicle (HMMWV) by deriving non dimensional ratios called π parameters. A Hardware In the Loop (HIL) setup is constructed and the resulting longitudinal dynamics of the scaled vehicle are validated against those of a full scale vehicle model. This is performed with the u...
