A decision making module for cooperative collision warning systems using Vehicular Ad-Hoc Networks

Using a Vehicular Ad-Hoc Network (VANET) communication for cooperative collision warning system can increase safety, convenience and efficiency in driving. Intelligent vehicles can collect information about the driving environment, the driver situation and more importantly other vehicles´ information using wireless communication. However, deciding what data to considered, what data to ignore and if and what action should be taken in different situations is a significant issue. In this work, we explore the use of a decision making module for accident situations which processes information from VANET communication and advises the driver based on the situation. Our decision making algorithm is a simple and effective algorithm that can be implement in each vehicle to assist the driver in certain situations. Rerouting to avoid traffic congestion caused by the accident is the major part of our decision making algorithm. This module has been implemented and evaluated using the Veins simulation.
