Development of automatic vehicle headway control law and a simulation tool

Vehicle following and its effects on traffic flow has been an active area of research. Human Driving involves reaction, delays, and human errors that has adverse effects on traffic flow . We can eliminate human errors by introducing a computer control system. The purpose of this research was to d...
