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] like 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, and...

Abstract

The invention discloses an intersection control method for an intelligent network connection vehicle. A special phase for the intelligent network connection vehicle is added to a conventional signal lamp phase; by applying a reservation idea and an optimization idea, the time and the expected speed of entering the intersection are assigned to each intelligent network connection vehicle entering the control range; after receiving the driving instruction, the intelligent network connection vehicle executes a distributed consistency protocol, enters the intersection at an expected speed within specified time, and rotates and drives around the virtual roundabout; in the conventional phase, other types of vehicles run according to the same traffic rule as the signal lamp intersection; and the intersection control center periodically optimizes the green light duration of each phase according to the signal timing optimization interval. According to the method, the advantages of the intelligent network connection vehicles and the advantages of the roundabout are combined, the average delay of the intelligent network connection vehicles is remarkably reduced, large-scale engineering transformation does not need to be carried out on the roundabout, and in other phases, the traffic rules are the same as those of an existing signal lamp roundabout, so that the safety and the acceptabilityof drivers are guaranteed.

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...
