Abstract

The invention discloses a method and system for coordinating traffic at an unsignalized intersection of intelligent networked vehicles, and relates to the technical field of intelligent transportation. The method includes the following steps: an MEC host acquires geographic information data and vehicle data within the range of a target intersection; and screens out the target vehicle; Sorting the target vehicles, selecting the first target vehicle at the current moment; determining the respective suggested speeds of the remaining target vehicles in the sorting according to the passing time of the first target vehicle, so that the remaining target vehicles can use their respective suggested speeds Travel at the target speed, and pass one by one according to the sort order. Compared with the prior art, the present invention has the following advantages: it effectively ensures the safe and efficient passage of vehicles within the range of the target intersection, does not require complex algorithms, is not limited by use conditions, and provides easy implementation for coordinated passage at unsignalized intersections. technical support.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method and system for coordinating passage of intelligent networked vehicles at unsignalized intersections. Background technique [0002] With the rapid development of intelligent transportation systems and intelligent network technology, the construction of intelligent network intersections is also gradually popularized and implemented. A smart networked intersection is a combination of sensor perception technology, fusion technology, V2X (Vehicle to Everything, information exchange between vehicles and the outside world) communication technology and traffic optimization algorithms, so as to realize the intersection between pedestrians, non-motorized vehicles and intelligent networked vehicles. Information transfer. Through V2X technology, all intelligent connected vehicles can transmit their own status information to the local MEC (Multi-Access Edge Comput...
