Research on Real-time Control of Traffic Lights Based on Traffic Flow

The control of road traffic lights and road traffic signs line set together to form an integral part of road traffic control and management.Traffic signal control has played an important role in the entire road traffic engineering,it is mainly used in traffic volume,traffic flow more conflict and complex intersections,as well as control the direction of traffic flow on certain road sections.For a number of deficiencies in the existing traffic signal control,a number of vehicles in the traffic junctions to guide the factors,the use of VC+ + to write semaphores real-time control program,in order to achieve real-time control of traffic lights.
