Traffic signal control system and method based on road condition traffic big data

Abstract

The invention provides a traffic signal control system and method based on road condition traffic big data. The method comprises the following steps: a client of a vehicle sending client information to a cloud platform; carrying out massive traffic data information cloud storage; dividing the data into real-time data and historical data according to time sequence; establishing a corresponding static database and a dynamic database according to the type of the data; generating a corresponding optimization control scheme and a coordination control scheme; determining road conditions of a control area according to the schemes, and setting corresponding configuration schemes; selecting the corresponding optimization control scheme; adjusting signal period, signal phase sequence and relative phase difference; and driving a signal lamp to execute an instruction transmitted based on the client. By utilizing the cloud storage and based on big data processing, trend is obtained, and an optimization scheme is made according to change rules; the optimal operation phase of the traffic signals is controlled, so that people are allowed to go out conveniently; and by comparing the collected real-time data with the historical data, the coordination control scheme is generated, so that the operation phase sequence, time (period) and phase sequence of the signal lamps can be adjusted in time, and emergency traffic conditions can be coped with.

Description

technical field [0001] The invention relates to the technical field of traffic signal control, in particular to a traffic signal control system and method based on road condition traffic big data. Background technique [0002] With the continuous development and progress of the country's economic construction, the number of transportation vehicles is increasing day by day, and the pressure on urban traffic is also increasing. In order to relieve traffic pressure and effectively guide vehicles on various roads, traffic lights are installed at intersections to guide and control the driving of vehicles; the disadvantage of traditional signal control methods is that a large number of detectors need to be arranged at intersections or road sections , the cost is relatively high, and the damage to the road surface such as coil detectors is also relatively serious. Moreover, once the coils are arranged, they cannot be adjusted, and the queue length at the intersection cannot be acc...
