Combined type intercommunication main line advanced lane changing and entrance multi-ramp linkage control system and method

Abstract

The invention relates to a combined type intercommunication main line advanced lane changing and entrance multi-ramp linkage control system and method, and belongs to the field of intelligent traffic. The system comprises an entrance ramp control module, a toll station open lane number control module and a main line advanced lane changing control module. The entrance ramp control module is arranged at a ramp confluence point connected with a hub intercommunication or service area and a toll station, and adjusts the traffic volume of each sub-ramp confluence into a main line by controlling the green light opening time of a signal lamp; the toll station open lane number control module is arranged at the entrance of the toll station, and adjusts the traffic volume on the highway by controlling the starting number of toll lanes; the main line advanced lane changing control module is arranged at the upstream of a main line and is 1 km to 2 km away from a confluence point, a variable information board is installed at the position, and an advanced lane changing strategy is issued through the variable information board. According to the invention, the expressway composite intercommunication traffic control capability can be enhanced, the traffic capacity of the main line confluence area is improved, and the traffic safety risk is reduced.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and relates to a composite intercommunication main line advance lane change and entrance multi-ramp linkage control system and method. Background technique [0002] With the continuous increase of road network density and the constraints of topography and other conditions, it is more and more frequent that the clear distance between adjacent new interchanges cannot meet the requirements of the regulations. The combination of lanes is set as compound interchange to meet the requirements, but the organization of compound interchange is complex, and the traditional ramp control is not suitable for performance. [0003] Therefore, it is very important to study the linkage control of advance lane change and entrance multi-ramp of compound intercommunication main line. SUMMARY OF THE INVENTION [0004] In view of this, the purpose of the present invention is to provide a composite intercomm...
