Research of real-time control algorithm for traffic lights based on CPU process scheduling

To solve the problem that current transport systems cannot provide real-time response to traffic changes, this paper proposes a real-time control algorithm for traffic lights based on CPU process scheduling to reduce the waiting time of vehicles. This paper proposes a system model of implementing the real-time algorithm. First, this paper designs the appropriate hardware system based on different algorithm requirements for traffic flow information. Then extract useful information through data processing. Finally, based on different requirements for fairness and access efficiency, this paper designs five different control algorithms. The algorithm this paper proposed can support countdown-time traffic lights; it will effectively improve the efficiency of traffic.
