Expressway entrance diversion and flow collaborative control technology

Abstract

The invention discloses an expressway entrance diversion and flow collaborative control technology, wherein the technology comprises the following steps of on the basis of expressway holiday traffic demand distribution information, obtaining expressway entrance and exit traffic demand OD information of different time periods every day through a multi-source data analysis technology, and then calculating the traffic demand quantity in an adjacent road section of each entrance and exit of the expressway at different moments. According to the technology, the flow of each entrance is adjusted andcontrolled through a core control strategy, so that traffic jam of the road section with insufficient passing capacity is avoided, and the traffic capacity reduction and the traffic accident risk caused by congestion are prevented, and therefore the traffic smoothness of all the road sections of the expressway is achieved, and the expressway main line passing efficiency is maximized; and the technology has a good effect on congestion prevention and flow control under the condition that large-area traffic congestion occurs on the expressway in holidays, and has a wide application range and a high application prospect in the aspect of intelligent traffic management of expressways in China.

Description

technical field [0001] The invention relates to the technical field of expressways, in particular to an expressway entrance diversion and flow cooperative control technology. Background technique [0002] With the development of economy and society, the continuous expansion of urban scale and the rapid growth of motor vehicles have caused the problem of "high-speed congestion disease" that occurs repeatedly every year during major holidays, which is related to the migration of a large number of people from other places. To drive smoothly on the expressway, the primary problem is to solve the traffic jam at the entrance of the expressway. However, the existing technology lacks the technology for the diversion of the entrance of the expressway and the coordinated control of the flow, and cannot effectively prevent the large-area traffic congestion of the expressway during holidays. Therefore, How to improve the traffic efficiency and service capacity of the expressway and alle...

[0002] With the development of economy and society, the continuous expansion of urban scale and the rapid growth of motor vehicles have caused the problem of "high-speed congestion disease" that occurs repeatedly every year during major holidays, which is related to the migration of a large number of people from other places. To drive smoothly on the expressway, the primary problem is to solve the traffic jam at the entrance of the expressway. However, the existing technology lacks the technology for the diversion of the entrance of the expressway and the coordinated control of the flow, and cannot effectively prevent the large-area traffic congestion of the expressway during holidays. Therefore, How to improve the traffic efficiency and service capacity of the expressway and alleviate the serious traffic jam during the holidays of the expressway is a technical problem that needs to be solved urgently
