Abstract Preview

This Technical Specification specifies system requirements for Traffic Impediment Warning Systems (TIWS). The

purposes of the warning system are that information collected by the infrastructure is automatically and quickly

provided to vehicles and reported to the traffic system operator, so vehicles can avoid secondary accidents. A

major function of the system is to save lives by speedier rescue activities and, a quicker clearing up of accidentcaused

congestion. This Technical Specification focuses on closed circuit television (CCTV) cameras as the

sensors, to detect traffic impediments using image processing and variable message signs as the communication

method to provide information to drivers.
