Cooperative control method and device for passenger cars and trucks on expressway exit ramp and equipment

Abstract

The invention discloses a cooperative control method and device for passenger cars and trucks on an expressway exit ramp and equipment. The method comprises the steps that: the expected speed of a main road exit control section is determined according to the running speed and density of vehicles of different types on an exit ramp section; when a passenger car driving-out demand exists on the inner side of a main road section and lane changing is needed, whether trucks run in a queue at the main road exit control section or not and whether the distance between the trucks is smaller than a lane changing safety threshold value or not are detected; the trucks are guided to increase the distance between the trucks when the trucks run in a queue and the distance between the trucks is smaller than the lane changing safety threshold value; when the distance between the trucks is larger than or equal to the lane changing safety threshold value, the trucks are guided to run at the expected speed. The invention aims to provide the cooperative control method for the passenger cars and the trucks on the exit ramp of the expressway under the vehicle-road cooperation environment on the basis of real-time data under the vehicle-road cooperation environment, so as to improve the safety coefficient and the passing efficiency of the exit ramp of the expressway and increase the passing capacity of the existing expressway.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a vehicle-road coordination-based method, device and equipment for the coordinated control of passenger and freight vehicles on an expressway exit ramp. Background technique [0002] The rapid development of the economy has led to a sharp increase in the freight volume of the expressway, resulting in a large proportion of expressway trucks, which has a great impact on the traffic operation status of the expressway. Compared with other roads, the expressway is a closed road, and vehicles can only leave the expressway through the exit ramp. At present, highways mainly use traffic signs and Internet navigation products to guide vehicles out of highway exit ramps. Due to the shielding effect of large trucks, platoon driving creates shielding obstacles for small vehicles to exit the expressway and change lanes, causing small vehicles to miss the opportunity to exit. With the...
