Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with specific embodiments.

[0032] This embodiment is based on the following assumptions:

[0033] 1) The impact of pedestrians and non-motor vehicles is not considered.

[0034] 2) The delay caused by information transmission and calculation is not considered.

[0035] 3) All intelligent connected vehicles can obtain their own accurate position, speed, and driving path (go straight, turn left, turn right).

[0036] Such as figure 1 As shown, this embodiment provides an intersection control method for intelligent networked vehicles, including the following steps:

[0037] 1) Set up an intersection control center at the intersection for interacting with ICVs and giving driving instructions. It has two main functions: calculate information from data sources such as vehicle detectors and networked vehicles and periodically perform signal timing; integrate its driving information and signal timing, ...

Abstract

An intersection control method for ICVs, which adds a special phase for ICVs to the conventional signal light phases; applies the idea of ​​reservation and optimization to assign each ICV entering the control range to enter the intersection The time and expected speed at the intersection; after receiving the driving instructions, the intelligent networked vehicle executes the distributed speed control algorithm, enters the intersection at the expected speed at the specified time, and rotates around the virtual roundabout; in the normal phase, other types of vehicles follow Drive under the same traffic rules as signal light intersections; the intersection control center periodically optimizes the green light duration of each phase according to the signal timing optimization interval. The present invention combines the advantages of intelligent networked vehicles and roundabouts, significantly reduces the average delay of intelligent networked vehicles, and does not require large-scale engineering transformation of intersections. same, thus ensuring safety and driver acceptance.

Description

technical field [0001] The invention belongs to the technical field of vehicle control at road intersections, and relates to an intersection control method for intelligent networked vehicles. Background technique [0002] For quite a long time in the past, the process of urbanization, the development of road network and the growth of car ownership have greatly improved people's travel conditions, but in recent years, related problems have gradually exposed: traffic congestion wastes a lot of travel For a long time, pollution such as car exhaust and noise plagued the surrounding residents, and the wider and wider roads made it more difficult and dangerous for pedestrians to travel. Since the advent of self-driving vehicles, they have attracted much attention because of the concept of replacing or assisting drivers to complete driving tasks more safely and efficiently. Under the vigorous promotion of governments and enterprises in various countries, the V2X technology based o...
