Method and device for controlling vehicle traffic at continuous intersections

Abstract

The invention discloses a continuous intersection traffic control method and device. The continuous intersection traffic control method comprises: step 1, collecting signal lamp information and vehicle information on vehicle running route; step 2, calculating a phase space-time diagram of N signal lamps on the vehicle running route according to the information collected in the step 1) in combination with pre-loaded map information; step 3, setting a speed vk, wherein k is equal to 1, 2, ..., n, and n is a natural number; step 4, judging whether a passing time of passing by the ith signal lamp at the speed vk is within a green light phase in the phase space-time diagram, if so, the speed vk is an effective speed ui, and on the contrary, entering step 3; step 5, calculating multiple groups of effective speed combinations passing by N intersections, figuring out the total oil consumption of each group of effective speed combinations, using the effective speed combination with the lowest total oil consumption as an economic vehicle speed, and prompting the economic vehicle speed to drivers. The continuous intersection traffic control method disclosed by the invention can be used for achieving the aim of economic driving.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic control, in particular to a method and device for controlling vehicle traffic at continuous intersections. Background technique [0002] With the continuous increase of car ownership, problems such as traffic efficiency, energy consumption and environmental pollution are becoming more and more serious. In actual traffic, an important factor that increases fuel consumption and emissions is the intersection. When a vehicle passes through an intersection and encounters a red light, it must stop and wait to pass. In the process of stopping and waiting, the car is mostly in an idle state. While idling, the car continues to consume fuel, emitting greenhouse gases and other harmful gases. How to improve traffic efficiency at intersections and reduce idling and fuel consumption of vehicles at intersections through technical means has become the focus of research by scholars at home and abro...

AI Technical Summary

Problems solved by technology

First of all, this technology is only suitable for arterial roads, and has limitations in the application of complex urban continuous intersections; second, this technology can prompt and optimize the traffic flow as a whole, and cannot be used for individual vehicles according to their different motion states and positions. Make corresponding speed prompts
