Intelligent Car Transportation System



Proposed IntelliCarTS (Intelligent Car Transport System), 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 a Global Positioning System (GPS) receiver aided with dead-reckoning sensors, enabling accurate location determination despite discrete GPS measurements. Two nearby vehicles periodically exchange information about their own movement in terms of exact position (obtained through GPS and dead-reckoning sensors) 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 simulates the proposed IntelliCarTS concept over a torus topology emulating the streets of Manhattan.
