Embodiment

[0071] A real-time control method for expressway vehicles based on edge computing in this embodiment, such as figure 1 As shown, it includes the following steps: S1: Construct a real-time control system for expressway vehicles, set a group of control units on the expressway at a rated distance, and connect each control unit through optical fiber communication;

[0072] The control unit includes:

[0073] The roadside perception module includes video and radar to monitor the vehicle speed and vehicle interval density in different section areas of the expressway in real time. The roadside perception module monitors the traffic volume and average speed of vehicles on the expressway in real time through video and radar equipment, and senses traffic emergencies such as traffic accidents, vehicle parking, spilled objects, and personnel entry.

[0074] The roadside perception system collects cross-sectional traffic volume, speed and other information and uploads the data every 500ms...

Abstract

The invention discloses an expressway vehicle real-time management and control method based on edge calculation. The problems that in the prior art, after an expressway accident or congestion occurs, an induction information issuing path is incomplete, and the traffic dredging efficiency is low are solved. The method comprises the following steps: S1, an expressway vehicle real-time management and control system is constructed, and a group of management and control units is arranged on an expressway at rated intervals; S2, the management and control unit monitors the vehicle running speeds of different section areas of the expressway in real time, judges the road traffic states of the different section areas, and obtains a suggested vehicle speed through edge calculation; and S3, each group of management and control units correspondingly publish suggested vehicle speeds of different lanes above the expressway. The suggested vehicle speed is calculated by monitoring different section areas in real time, the suggested vehicle speed is displayed on different lanes above the expressway, speed change and lane change are guided through communication with vehicles, and the induction information issuing approach is perfected.

Description

technical field [0001] The invention relates to the field of expressway vehicle management and control, in particular to a real-time control method for expressway vehicles based on edge computing. Background technique [0002] At present, the information perception of highways on road traffic congestion, accidents and other traffic events mainly relies on personnel watching and monitoring. After personnel discover the incident, they report to the traffic police or relevant highway management departments, resulting in information lag. Measures are taken by relevant highway management departments. Diverting traffic can easily lead to adverse effects such as secondary accidents; at the same time, due to the untimely information prompts on the current expressway and the imperfect release channels of induced information, information such as road conditions and vehicle speeds cannot be sent to subsequent vehicles in real time and accurately, which affects the driver's travel experi...
