CASD: A Framework of Context-Awareness Safety Driving in Vehicular Networks

Inspired by the advancement of vehicular networks and increasing concerns on driving safety, this paper proposes a framework of Context-Awareness Safety Driving (CASD). In vehicular networks, vehicles communicate with each other and share a variety of information. By utilizing those capability, CASD provides vehicles with a class-based safety action plan that considers three situations such as the Line-of-Sight unsafe, the Non-Line-of-Sight unsafe and the safe situations. In the Line-of-Sight unsafe situation, a hybrid take-action scheme is provided. If human's action fails, the vehicle will take over the driving control to guarantee the minimum risk. A timing for the vehicle to take over the control is based on an optimized threshold by examining context information. Moreover, a dynamic path maneuver planning scheme is suggested to avoid a crash in real-time. The driving safety can be substantially improved using CASD.
