Intelligent ramp traffic control machine, system and method

Abstract

The invention provides an intelligent ramp traffic control machine, system and method and belongs to the field of intelligent traffic control. The intelligent ramp traffic control machine comprises a microprocessor module, a fault detection module, a signal lamp output module, a terminal, a vehicle detecting input module and a communication module. The microprocessor module is connected with the communication module, the signal lamp output module, the vehicle detecting module and the fault detecting module respectively. The fault detecting module is further connected with the signal lamp output module. The terminal is connected with the vehicle detecting input module and the signal lamp output module respectively. According to the arrangement, flow of the ramp exit of the urban expressway is controlled, traffic jam on the ramp exit and the main street of the expressway is improved, and smooth traffic of the expressway and the adjacent service road is guaranteed.

Description

technical field [0001] The invention belongs to the field of intelligent traffic control, and in particular relates to an intelligent ramp traffic controller, a control system and a control method. Background technique [0002] The urban expressway is the main artery of the urban road network. It satisfies the sustainable development of the city with its fast, connected and large-capacity traffic functions. However, with the rapid increase in the number of motor vehicles in my country and the saturation of infrastructure construction, urban traffic pressure getting bigger. Its operating status directly affects the traffic status of the entire urban road network. The urban expressway ramp (referring to the entrance and exit of the expressway), as the intersection node of the urban expressway and the surrounding road network, plays an important role in regulating the traffic flow of the road network and improving the utilization efficiency of the expressway. In recent years, ...

Problems solved by technology

[0004] At present, ramp signal machines at home and abroad have a variety of control strategies for ramp signal lights, such as fixed cycle mode, flow detection mode, speed detection mode, occupancy rate detection mode, etc., all of which use fuzzy control methods, and there is an opening or closing of the ramp. The control response speed is slow, not timely and accurate, and the efficiency is not high. It is impossible to quickly, accurately and efficiently turn the ramp signal light into a red light when the expressway is congested, so as to restrict the ramp vehicles from entering the expressway and relieve traffic congestion on the expressway. Immediately turn on the green light to let the ramp vehicles enter the expressway
