Vehicle speed guidance method, device, equipment and medium based on correlation degree of adjacent intersections

Abstract

The embodiment of the invention discloses a vehicle speed guiding method and device based on the correlation degree of adjacent intersections, equipment and a medium. When the method is executed by aroadside system or a cloud, the method comprises the steps that according to real-time road information of a target intersection and an adjacent intersection, and the road information comprises entityroad information and signal lamp information of the target intersection and the adjacent intersection, the influence degree of a real-time road environment on path selection and passing vehicle speedof a target road vehicle is determined; the method further includes determining the association degree of the target intersection and the adjacent intersection according to the influence degree; andif the association degree is greater than a preset association degree threshold, sending the road information to a network connection vehicle-mounted terminal, so that the vehicle-mounted terminal provides vehicle speed suggestions to guide the vehicle speed based on the road information and the vehicle driving information. According to the embodiment of the invention, the vehicle-mounted terminalcan guide the vehicle speed through the road information acquired by the roadside system or the cloud of the target intersection, and the problems of information redundancy and resource waste causedby sending a large amount of road information are avoided.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of roads and traffic, and in particular to a vehicle speed guidance method, device, equipment and medium based on the correlation degree of adjacent intersections. Background technique [0002] Vehicle speed guidance is a technology that calculates the speed range that allows the vehicle to pass through the intersection with a green light when it reaches an adjacent intersection under the condition of obtaining the signal timing of the downstream intersection, and sends a reminder to the driver. [0003] The existing speed guidance at intersections is mainly non-network-connected and uses roadside display screens to send speed guidance information to drivers. But the disadvantage of this is that when the vehicle drives away from the display screen on the roadside, it will not be able to obtain the speed guidance suggestion, and it cannot provide specific speed guidance for the vehic...

AI Technical Summary

Problems solved by technology

If the vehicle speed guidance system provides the driver with suggested vehicle speeds in the direction of traffic flow at all adjacent intersections without knowing the specific driving route of the vehicle, it will not only cause too much information for the driver to quickly obtain the content he needs, but also Causes waste of computing and communication resources
