Problems solved by technology
[0002] At present, in urban road traffic, the time setting of the red and green lights of the traffic lights at each intersection is fixed. Unless the traffic police command or adjust manually on the spot, the time of the traffic lights will not change. The traffic flow during the time period is changing. If the time of the traffic light remains unchanged, the red light will be too long when the traffic flow is small, and the green light will be too short when the traffic flow is heavy, resulting in road congestion and pressure on urban road traffic.

This application relates to the field of big data. This application discloses a method and related equipment for adjusting the duration of traffic lights based on road condition prediction. The method includes: obtaining historical traffic data of the current road; performing statistics on the historical traffic data of the current road Analyze to obtain the historical road conditions of each time period of the current road; predict the road conditions of the current road in the current period according to the historical road conditions, and obtain the average congestion of the current road in the current period according to the historical traffic data corresponding to the congestion situation rate, and adjust the duration of traffic lights on the current road according to the predicted road conditions of the current road at the current period and the average congestion rate. This application obtains the historical data of each road at each time period, predicts the congestion situation of each road at each time period according to the analysis of the historical data, and adjusts the traffic lights according to the predicted congestion situation, which can effectively improve the use efficiency of traffic lights and reduce road traffic pressure. Improve vehicle traffic efficiency.
Description
technical field [0001] The present application relates to the field of big data, in particular to a method and related equipment for adjusting the duration of traffic lights based on road condition prediction. Background technique [0002] At present, in urban road traffic, the time setting of the red and green lights of the traffic lights at each intersection is fixed. Unless the traffic police command or adjust manually on the spot, the time of the traffic lights will not change. The traffic flow during the time period is changing. If the time of the traffic lights remains the same, the red light will be too long when the traffic flow is small, and the green light will be too short when the traffic flow is heavy, resulting in road congestion and pressure on urban road traffic. Contents of the invention [0003] The purpose of this application is to address the deficiencies in the prior art and provide a method and related equipment for adjusting the duration of traffic l...
