Abstract

Wireless Vehicular Network is a system to realize information interoperability between vehicles and human, vehicles and roads, vehicles and vehicles, and transport facilities, through the network information exchange, in order to achieve the effective monitoring of the vehicle and traffic flow. While the essence of wireless vehicular network is actually to improve traffic efficiency and avoid accidents. Thus this paper aims to propose a new safety indicator called time gap interval for safe following distance (TGFD). TGFD incorporates vehicle dynamics and driver behavior factors that include the time component to broadcast and propagate suitable safety messages in vehicular ad hoc network (VANET) environment. Results from this simulation study indicate that the TGFD is comprehensive safety indicator for safety analysis.
