Traffic flow-based adaptive traffic light control system and method

Abstract

The invention provides a traffic flow-based adaptive traffic light control system. The system comprises a waiting traffic flow sensor, a monitoring traffic flow sensor, an intelligent lane indicator lamps and a traffic server; the waiting traffic flow sensor is arranged at the lane exit of a traffic node, performs real-time monitoring and statistics on the number of vehicles waiting on lanes in each direction at present and provides data to the traffic server in real time; the monitoring traffic sensor is arranged in front of the lanes in each direction, performs real-time monitoring and statistics on the number of vehicles entering the lanes in each direction and provides data to the traffic server in real time; and the intelligent lane indicator lamps are arranged the lane exit of the traffic node, specifically implement lane traffic light timing schemes fed back by the traffic server, and set corresponding lane indicator lamps; the traffic server is coupled to the waiting traffic sensor and the monitoring traffic sensor, receives the data sent by the waiting traffic flow sensor and the monitoring traffic flow sensor and calculates the traffic light timing schemes of the indicator lamps of each intersection based on the data and sends the lane traffic light timing schemes to the corresponding intelligent lane indicator lamps so that the intelligent lane indicator lamps can implement the lane traffic light timing schemes.

Description

technical field [0001] The invention relates to the field of urban traffic management, in particular to an adaptive traffic light control system based on traffic flow and a scheduling method thereof. Background technique [0002] With the advancement of urbanization and the rapid increase in the number of vehicles, the contradiction between vehicles and road surfaces in cities has become increasingly prominent. Especially in large cities such as the first and second tier cities and at the entrances and exits of the main highways connecting cities, the congestion phenomenon is very prominent during the peak period of commuting or holidays. [0003] In the past, simply widening the road surface was only a palliative, not a permanent solution. On the one hand, the cost of this method is high, and a large amount of money needs to be invested in infrastructure construction; on the other hand, this method does not fully consider the impact of the time period on traffic flow, and ...

AI Technical Summary

Problems solved by technology

On the one hand, the cost of this method is high, and a large amount of money needs to be invested in infrastructure construction; on the other hand, this method does not fully consider the impact of the time period on traffic flow, and adjust the traffic light timing in each direction of the traffic node according to the change of traffic flow.
