Abstract

The invention discloses an internet-of-vehicles-based intersection signal light split regulation method. The method comprises the following steps: performing vehicle GPS (Global Positioning System) road correction and calculating a road average speed; establishing an average speed estimation model; establishing a single-intersection signal light six-phase control system model; solving duration of each phase by using a particle swarm algorithm; performing dynamic updating of each phase time of an intersection. Field experiment application proves that the internet-of-vehicles-based intersection signal light split regulation method has a good effect, can effectively improve the vehicle traffic efficiency of the intersection and is applicable to occasions such as intersection signal light split regulation.

Description

technical field

[0001] The invention belongs to the field of traffic flow parameter detection and control, relates to a method for adjusting the green signal ratio of signal lights at intersections in traffic control, and particularly designs a method for adjusting the green signal ratio of signal lights at intersections based on Internet of Vehicles. Background technique

[0002] Effective control of signal lights at intersections is an important direction in the field of traffic control, especially at intersections with large traffic volumes and complex traffic conditions, the effective control of signal lights becomes particularly important. Therefore, it is of great significance to improve the control effectiveness of traffic lights at intersections.

[0003] In the urban road traffic system, an intersection is a hub where two roads intersect each other and serves as a direction conversion hub. Some big cities in the world such as New York, the speed of a vehicle in the...
