A real-time vehicle safety system

With the increase of vehicle amount all over the world, vehicle safety has become a tremendous problem. Chained accidents, which result in numerous losses of lives and properties, happen due to the fact that the following drivers are unaware of the accident occurrence. In this paper, a real-time vehicle safety system is proposed. A prototype test platform, consisting of collision detection and classification module, vehicle-to-vehicle (V2V) communication module and graphic user interface (GUI) module, has been built for validating the performance. 12 sensors are installed in collision detection module. Threshold under rule based strategy is adopted for collision classification. We also propose a GPS based AODV (GBAODV) protocol for V2V communication application. One full version and eight sets of portable version subsystems are implemented for road test. The experiment results validate the performance of this safety vehicle system.
