A dynamic control method for expressway toll stations and surrounding intersection groups

Abstract

The invention relates to a dynamic control method for expressway toll stations and surrounding intersection groups. The overall road network of expressway entrance and exit ramps, toll stations and surrounding intersection groups is divided into: key sub-regions of entrance and exit ramps, toll stations and connecting intersections, Other intersection group sub-regions around toll stations; establish a cooperative control mechanism between adaptive toll stations and connection intersections in toll stations and connecting intersection sub-regions, and establish fuzzy logic within the intersection group in other surrounding intersection group sub-regions Control mechanism; call the toll station traffic capacity regulation model to realize the dynamic adjustment of the actual traffic capacity of the entrance and exit toll channels. The method of the present invention proposes for the first time a cooperative control model for dynamically changing the traffic speed of expressway toll stations and intersection groups according to different traffic conditions, and an adaptive control model for dynamically changing the traffic capacity of entrance and exit toll passages, which is suitable for expressway toll stations and surrounding areas Regional Road Network Cooperative Control of 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.
