A method for calculating phase duration of rasterized signals at intersections in a vehicle-road collaborative environment

Abstract

The invention discloses a signal phase duration calculation method for an unsplit vehicle queue at a signal point signal intersection under the vehicle-road cooperation environment based on intersection internal space rasterization. The method comprises the steps that the vehicle performs data and information exchange with surrounding vehicles and roadside facilities through vehicle-vehicle / vehicle-road communication under the vehicle-road cooperation environment, and the time used for passing through the intersection conflict point of the vehicle queue is calculated by using the obtained vehicle real-time position, driving speed, acceleration and other data through the technology of intersection internal space rasterization and acts as the calculation basis of signal control phase duration. According to the city single point signal intersection phase duration calculation method, the intersection internal space-time resources can be fully utilized so that the traffic operation efficiency of the intersection can be effectively enhanced, and all directions of vehicles can efficiently and orderly pass through the intersection without conflict.

Description

technical field [0001] The invention relates to the technical field of vehicle-road cooperative driving control, in particular to a method for calculating the signal phase duration of an inseparable vehicle queue at a single-point signalized intersection in a vehicle-road collaborative environment based on the internal space grid of the intersection. Background technique [0002] In recent years, with the rapid development of the economy and the acceleration of urbanization and industrialization, the number of motor vehicles is also increasing. Relevant data show that the number of motor vehicles in my country has exceeded 280 million and is still growing at a high speed. As a result, a series of problems such as aggravated environmental pollution, increased number of traffic accidents, and traffic congestion have emerged. At present, traffic congestion in my country has spread from super-large cities such as Beijing, Shanghai, and Guangzhou to provincial capitals and even se...

Problems solved by technology

[0004] Based on the analysis of the existing research, the results show that most of the current signal control models at single-point intersections in the vehicle-road collaborative environment are constructed with a single vehicle as the object, and vehicles are not organized into fleets.
