Embodiment Construction

[0024] like Figure 1-2 Shown; A kind of traffic signal control system based on road condition traffic big data is composed of: client 1, cloud virtual machine 2, data storage server 3, data analysis server 4, signal control center 5, regional traffic signal control machine 6 and Composition of signal lights 7;

[0025] Client 1, used for the client on the vehicle to send client information to the cloud platform;

[0026] Cloud virtual machine 2, which is used to obtain the road condition information of vehicles and traffic lights at the intersection of each LINK section on the road obtained from Gaode map;

[0027] The data storage server 3 is used to obtain data, divide the data into real-time data and historical data according to time series, and use the known road network structure parameters and intersection signal timing parameters combined with the short-term prediction method of relevant traffic flow parameters to generate traffic Data information and store it for re...

Abstract

The invention provides a traffic signal control system based on traffic big data. The traffic signal control system comprises a client, a cloud virtual machine, a data storage server, a data analysisserver, a signal control center, a regional traffic signal control machine and signal lights; a static database and a dynamic database are established according to data types; corresponding optimal control scheme and coordinative control scheme are generated; road condition of a control region is determined according to the schemes, and a corresponding configuration scheme is set; the corresponding optimal control scheme is selected; signal period, signal phase sequence and relative offset are adjusted; the traffic lights are driven to execute an instruction transmitted on the basis of the client, a cloud is used for storage, trend is grasped on the basis of big data processing, and an optimal scheme is made according to change rules; the optimal operation phase of the traffic lights is controlled, by means of a coordinative control scheme generated through comparison of real-time collected data with historical data, operation phase sequence, time and offset of the traffic lights can be adjusted timely, and unforeseen traffic conditions are handled.

Description

technical field [0001] The invention relates to the technical field of traffic signal control, in particular to a traffic signal control system 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 accurately det...
