Embodiment Construction

[0027] The present invention will be further described below in conjunction with specific drawings.

[0028] like figure 1 As shown, the urban expressway main line and ramp cooperative control system of the present invention includes a signal machine, a detector, a signal lamp and a control system; Judgment selects the corresponding preset scheme and sends it to the signal machine, and the signal machine executes the corresponding scheme according to the system control command.

[0029] The detector includes a ramp detector D1, a main line downstream detector D2 and a main line upstream detector D3, the output terminals of the ramp detector D1, the main line downstream detector D2 and the main line upstream detector D3 are connected to a signal machine, and the ramp detector D1 It is used to detect the queuing situation of the ramp, the downstream detector D2 of the main line is used to detect the congestion overflow of the downstream section, and the upstream detector D3 of ...

Abstract

The invention relates to a cooperative control method and system for the trunk line and ramp of a city expressway, and belongs to the technical field of road traffic signal control. The system is characterized in that the system comprises a detector which is used for detecting the traffic flow states of the ramp and the trunk line; a signal lamp which is used for controlling the opening, closing and discharging of the ramp and the trunk line; a signal annunciator which is connected with the detector, the signal lamp and a control system, and is used for collecting the traffic flow operation state data of the ramp and the trunk line and uploading the data to the control system, and controlling the signal lamp according to a control command of the control system; and the control system whichselects a corresponding preset scheme according to a triggering threshold value, and transmitting the preset scheme to the signal annunciator. The system solves problems that a conventional section collection index is not accurate and the effectiveness is not high. The system employs a trunk line and ramp signal lamp linkage control strategy and scheme according to different scenes, and achievesthe cooperation of traffic organization and a signal control scheme and the dynamic response control of the ramp.

Description

technical field [0001] The invention relates to a method and system for coordinated control of a main line of an urban expressway and a ramp, and belongs to the technical field of road traffic signal control. Background technique [0002] In recent years, with the acceleration of urban motorization, the peak hours of the main line of the expressway show periodic, long-term, and long-distance traffic jams. The junction between the main line of the expressway and the ramp and the adjacent areas have become the source of normal traffic congestion. On the one hand, there are many problems in the planning, design, and construction of expressways and ramps; on the other hand, there is a lack of refined traffic organization and control measures for expressways, short ramps, and connections between off-ramps and the ground. The coordinated control of the main line and the ramp of the expressway is rarely considered, which is also an important reason for the congestion in the connect...
