Cooperative collision warning for driving assistance

Whatever type of distraction during the driving of a vehicle can compromise the safety of not the driver, but also of all drivers present on the highway. Using the mobile while driving is the greatest examples of this problem at a global level. In this regard, a system that helps the driver improve and keep up the attention on the road, could be a solution. This paper proposes a cooperative assistance system which, through the use of communication among vehicles, exchanges messages with the objective to warn about the presence of other vehicles around an ego vehicle and assess the risk situation. This system was evaluated through the proposal of a new version of a simulation framework. This new version, besides considering a bidirectional communication among all the vehicles present in the communication coverage, also considers the time delay variation regarding the distance among vehicles. The results from the system simulation allowed us to observe the time delay effect in the proposed system through the assessment of three collision situations chosen for the tests. In this proposal, it was also possible find also a range of coverage distances for the warnings about other vehicles around of an ego vehicle
