Design of an intelligence traffic light controller (ITLC) with VHDL

The intelligence traffic light controller is considered for the busy time on the road when people are going to work and the traffic light timing control. Traffic congestion increases because the current traffic light controller only allocates a fixed time control. ITLC can reduce the waste time to drivers on the road. In this paper the traffic lights of main roads are controlled with fixed time while narrow roads are controlled autonomously by sensors. ITLC's efficiency is increased when there are fewer vehicles on the narrow road. The experimental result shows that the efficiency of the ITLC can achieve a maximum 36%.
