Real-time traffic guidance and control integrated system and implementation method thereof

Abstract

The invention provides a real-time traffic guidance and control integrated system and an implementation method thereof. A real-time traffic guidance and control integrated coordination system is applied to the network traffic flow. The real-time traffic guidance and control integrated system comprises an information acquisition and processing module and a guidance and control integrated module, wherein the information acquiring and processing module comprises an information acquisition unit which is arranged on an information acquisition site and is used for acquiring traffic information and an information processing unit for pre-processing the traffic information; the guidance and control integrated module comprises a signal control optimizing unit for producing traffic control parameters, a traffic state judging unit for producing initial traffic state information and a traffic state issuing unit for producing road traffic state information; and the guidance and control integrated module receives the pre-processed traffic information and generates a traffic control and guidance scheme applied to the network traffic flow.

Description

technical field [0001] The invention relates to a traffic coordination system, in particular to an integrated coordination system for real-time traffic deduction and control. Background technique [0002] Traffic guidance and control system is the core content of intelligent transportation system research. The traffic guidance system can provide travelers with road network traffic status information, so that travelers can make reasonable use of the traffic network, and finally realize the optimal distribution of communication in space. [0003] The SCATS system is a traditional traffic control system, which selects parameters with each subsystem as a unit, and then combines each subsystem to achieve overall coordinated control. figure 1 Shown is the layout diagram of the traditional SCATS traffic control system information collection equipment. The collection equipment (represented by a rectangle in the figure) is arranged 5-15 meters behind the stop line at the entrance A...

AI Technical Summary

Problems solved by technology

The traditional system is not complete in terms of traffic information collection, information release data space use, and time use. The information collection in space loses the key traffic information collection near the stop line, and the key traffic information cannot be used in the information category. Control information, in terms of traffic information collection and upload frequency, is the average length of time selected according to the experience value of the release cycle, and the status of each displayed road section is refreshed according to a uniform cycle, which loses the timeliness of road network status release, and directly uses unrelated traffic in each cycle Information data, lost analysis of traffic status change trends
