Design of a Driver Assistant System Based on Vehicular Communications Using Fuzzy Logic

In this paper a novel fuzzy driver assistant system is introduced which takes advantage of the information provided by vehicular communications. In the proposed system, each vehicle receives some information such as speed, density and drivers’ violation status from the vehicles in its vicinity. Then the danger level of each neighboring vehicle is evaluated by means of a fuzzy decision system. Finally the system suggests appropriate actions to improve safety of the vehicle. The proposed system also can be used for making lane changing maneuvers (such as overtaking, turning to left and turning to right) safer. Results of extensive simulations show that our driver assistant system decreases the number of potential accidents by 60%. Moreover, the number of accidents caused by overtaking, turning to left and turning to right is decreased by 77%, 74% and 82% respectively.
