Dynamic regulation method for expressway toll stations and surrounding intersection groups

Abstract

The invention relates to a dynamic regulation method for expressway toll stations and surrounding intersection groups. The method comprises the steps of dividing an overall road network of the expressway entrance and exit ramps, the toll stations and the surrounding intersection groups into: key subareas of the entrance and exit ramps and the toll stations and connected intersections and other intersection group subareas around the toll stations; establishing a self-adaptive cooperative control mechanism between the toll stations and the connected intersections at the toll station and connected intersection subareas and establishing a fuzzy logic control mechanism in the intersection groups in the other surrounding intersection group subareas; and calling a toll station traffic capacity regulating model to realize the dynamic adjustment of the actual traffic capacity of entrance and exit toll channels. The method disclosed by the invention has the beneficial effects that a cooperativecontrol model for dynamically changing the traffic rate of the expressway toll stations and the intersection groups according to different traffic states and an self-adaptive regulation model for dynamically changing the traffic capacity of the entrance and exit toll channels are firstly proposed; and the method is suitable for the cooperative control of regional road networks of the expressway toll stations and the surrounding intersection groups.

Description

technical field [0001] The invention relates to the technical field of road traffic information engineering and control, in particular to a dynamic control method for expressway entrance and exit toll stations and connected urban road signal intersections. Background technique [0002] The vast majority of expressways in our country are closed toll roads, and toll stations are set up at the entrances and exits of expressways for toll control. The entrance and exit ramps, toll stations and urban road intersection areas are important road sections where the expressway and the urban road network are critically connected. However, they are bottleneck points where the traffic flow is not coordinated, and congestion often occurs, affecting the smoothness of the two road networks. Connected with. With the continuous expansion of the city and the rapid development of the social economy, the Ring Expressway has gradually become urbanized and has gradually become the only way for cit...

Problems solved by technology

In addition, the role of my country's expressway toll stations is only for the payment of vehicle tolls, the degree of utilization is low, and its traffic control function has not been effectively developed and utilized.
