Embodiment Construction

[0032] The following examples are used to further illustrate the present invention.

[0033] The traffic control system for improving road traffic capacity of the present invention comprises a plurality of traffic control stations arranged on road sections, and the plurality of traffic control stations are connected to a host computer; wherein each traffic control station comprises:

[0034] Traffic flow detection unit: the interval is 500-2000 meters and is arranged on three traffic flow detection units of the cross-section of traffic flow direction road section, is successively traffic flow detection unit I, traffic flow detection unit II and traffic flow detection unit III, for collecting traffic flow information, and calculate the road occupancy rate data according to the collected traffic flow information; the distance between the traffic flow detection unit I and the traffic flow detection unit II is 500 meters, and the traffic flow detection unit II and the traffic flow ...

Abstract

The invention discloses a traffic control system for improving the road capacity. The traffic control system comprises a traffic flow detection unit, a data analyzing and discrimination unit, a local control unit and a variable information plate driving unit; the data analyzing and discrimination unit and an upper computer as well as the local control unit of a command center are connected and can realize data exchange; and the local control unit is respectively connected with the traffic flow detection unit and the variable information plate driving unit, and can realize data exchange respectively with the traffic flow detection unit and the variable information plate driving unit. By changing the method for setting fixed speed limit standard of the traditional express way section, the invention has the advantages that the upper limit speed value is ensured to be changed according to the variation of real-time traffic flow to ensure the stability of traffic flow, thus the average running speed of vehicles can be improved, the parking times can be reduced, the pollutant emission can be lowered, and the energy consumption can be decreased.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a traffic control system which can control the corresponding speed limit value according to the actual traffic flow of urban expressways. Background technique [0002] Expressway is the main road of urban traffic. It can effectively separate the medium and long-distance traffic capacity of a certain scale from short-distance traffic, and at the same time allow a reasonable transfer between the internal roads of the city and the transit expressways on the outskirts of the city. with convergence. There are no intersections throughout the expressway, and vehicles are driven separately, which can provide road users with a high level of service. The expressway plays a key role in the entire urban road network and is the main artery of the entire urban traffic. However, with the rapid growth of traffic travel demand, the expressway often has traffic congestion. How to a...
