Emergency vehicle signal control method and device based on front-end and rear-end cooperative control, and storage medium

Abstract

The invention provides an emergency vehicle signal control method based on front-end and rear-end cooperative control, which is applied to the technical field of vehicle signal control, and comprisesthe following steps: planning an emergency navigation route through vehicle-mounted software, and submitting an emergency navigation task application; confirming that the emergency navigation task passes the auditing; scanning a currently existing emergency task and confirming whether the emergency navigation route needs to be modified by a rear-end auxiliary control system, and if yes, sending the modified emergency navigation route to the front-end emergency vehicle so that the front-end emergency vehicle can update the emergency navigation route; acquiring a traffic signal corresponding tothe emergency navigation route and authorizing the traffic signal control right of the front-end emergency vehicle by the rear-end auxiliary control system; and enabling running of the front-end emergency vehicle according to the emergency navigation route and the traffic signal control right. By applying the method of the invention, the control right of the emergency vehicle at the signal controlintersection is guaranteed so as to guarantee the priority pass right and the overall traffic operation safety.

Description

Technical field [0001] The present invention relates to the technical field of emergency vehicle driving control, and in particular to an emergency vehicle signal control method, device and storage medium based on front and rear cooperative control. Background technique [0002] With the rapid development of society, the number of cars continues to grow, and urban traffic is more complicated. Emergency vehicles such as ambulances and fire trucks are an important part of the urban traffic flow. The form of emergency vehicles is affected by complex traffic conditions. Excluding external factors will cause the emergency vehicle rescue response to be slow. [0003] In the prior art, the vehicle-road coordination technology can improve the efficiency of traffic control and alleviate traffic congestion to a certain extent, but the vehicle-road coordination often requires the addition of on-board hardware sensing equipment, and the hardware signal control equipment in the road network nee...

[0002] With the rapid development of society, the number of cars continues to grow, and urban traffic is more complicated; emergency vehicles such as ambulances and fire engines are an important part of urban traffic flow, and the form of emergency vehicles is affected by complex traffic conditions. Excluding external factors will cause the slow response of emergency vehicles

[0003] In the existing technology, vehicle-road coordination technology can improve traffic control efficiency and alleviate traffic congestion to a certain extent, but vehicle-road coordination often requires the addition of on-board hardware sensing devices, and the need to update hardware signal control devices in the road network, making it difficult to implement Larger, higher R&D costs, and more importantly, there are potential safety hazards in the direct vehicle-road coordinated signal control. This method often ignores the integrity and relevance of traffic signal control and the suddenness of traffic incidents.
