A method for flow diversion and flow cooperative control at expressway entrance

Abstract

The invention discloses a flow diversion and flow cooperative control method at an expressway entrance. Information, and then calculate the traffic demand in the adjacent sections of each entrance and exit of the expressway at different times. The present invention adjusts the traffic flow of each entrance under control through the core control strategy, so as to avoid traffic jams on road sections with insufficient traffic capacity, prevent traffic capacity decline and traffic accident risks caused by traffic jams, and realize smooth traffic in each road section of the expressway, so as to realize the expressway The main line traffic efficiency is maximized. This technology has a good effect on congestion prevention and flow control in the case of large-scale traffic congestion on holiday expressways. It has a wide range of applications and good application prospects in the intelligent traffic control of expressways in my country.

Description

Technical field [0001] The present invention relates to the field of highway technologies, and more particularly to a high-speed road inlet shunt and flow synergistic control method. Background technique [0002] With the development of economic and social, the expansion of urban scale and the rapid growth of motor vehicles have caused a "high-speed congestion disease" problem that has repeatedly episodes of the year, and is related to a large population migration in the field, to achieve during holidays. On the highway, the primary problem is to solve the traffic jam at the entrance of the highway, and the prior art lack of technology for the entrance to highway entrance and traffic synergies control, and cannot effectively prevent the large-scale traffic congestion of the expressway when the holiday is. How to improve the high-speed efficiency and service capabilities, alleviate the serious phenomenon of traffic jams during the holidays of highways, is a technical problem to be...

Problems solved by technology

[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
