Design Approach for Anti-collision Mechanism between Vehicle to Vehicle for Improving Safety Operation In Intelligent Transportation System

摘要

InVeTraS (Intelligent Vehicular Transportation System) is proposed as a Vehicle-to-Vehicle (V2V) anti-collision mechanism that determines estimates and absolves collision courses between two or more vehicles based on a correlative and cooperative wireless networking concept. The problem of collision avoidance is abstracted to the generic problem of location awareness and subsequent periodic information exchange (between vehicles). To enable location awareness, the mechanism uses one of two techniques: a Global Positioning System (GPS) receiver aided with dead-reckoning sensors or a RADAR based measurement system. Two nearby vehicles periodically exchange information about their own movement in terms of exact position and local clock time. Using these inputs, vehicles determine whether or not they are on a collision course with each another. A Communication Cluster (based on the concept of mobile ad-hoc peer-to-peer networking) is formed, that facilitates the development of a vehicular network characterized by self organization, fault-tolerance, scalability, cooperation and cost efficiency. These characteristics enable avoidance of collision between vehicles in an adaptive and dynamic set up. The paper proposed InVeTraS concept by emulating the streets of Manhattan.
