specific Embodiment

[0086] The setting of a toll station at the entrance of a certain expressway is as follows: figure 2 shown. According to the OD volume of each entrance and exit of the expressway, the most critical congested road section is determined, and the expressway is divided into different sections such as image 3 shown; as Figure 4 As shown, each toll station will pre-distribute the vehicles entering the toll station according to different driving directions, and adjust the traffic passing rate of each toll station, so as to achieve the purpose of preventing local congestion of the expressway;

[0087] Assuming a two-way eight-lane highway section, the traffic volume of each entrance and exit of the expressway at different times of the day has been obtained, and the traffic flow operation status of the expressway at a certain period of time is analyzed, and the traffic demand of each section is calculated according to the volume of each entrance and exit during this period. Analyz...

Abstract

The invention relates to an expressway entrance diversion and flow coordination control method for preventing local traffic congestion. The method comprises the steps of firstly, obtaining traffic demand information of entrances and exits on an expressway; secondly, calculating the traffic demand amount in adjacent road sections of each entrance and exit at different moments; thirdly, analyzing the traffic demand and traffic capacity of each section on the whole expressway, and judging whether or not the traffic flow of each road section is over-saturated. For road sections with the traffic demands greater than traffic capacity, according to the distribution of the traffic demands, vehicles which are about to enter toll stations are subjected to diversion in advance through an electronic information board, the railing lifting and falling cycle of all the upstream entrance toll stations is controlled, and the optimal traffic volume of each entrance is adjusted through a core control strategy. The expressway entrance diversion and flow coordination control method has good effects on congestion prevention and flow control under the condition of frequent traffic congestion in the localroad sections of the expressway, and has a wide application range and good application prospects in the aspect of intelligent traffic management and control over expressways in China.

Description

technical field [0001] The invention belongs to the technical field of traffic control and intelligent traffic, and in particular relates to an expressway entrance diversion and flow cooperative control method for preventing local traffic congestion. Background technique [0002] With the rapid increase of expressway construction mileage in my country and the rapid growth of motor vehicle ownership, expressway traffic demand and traffic flow have increased sharply, increasing the pressure on expressway traffic, and the traffic capacity of some sections of the expressway network has been unable to meet the existing demand. , especially during holidays, which affects the operating efficiency of the entire expressway network, especially during peak traffic hours, when expressway traffic demand is greater than capacity, leading to frequent expressway traffic congestion, which not only reduces expressway traffic efficiency, And increased conflict and friction between vehicles. The...
