Abstract

The invention relates to the technical field of intelligent traffic and discloses a multilayer fuzzy division method based on an emergency traffic flow priority level. The method includes the following steps of firstly, determining emergency traffic flow priority demand intensity, secondly, determining emergency traffic priority control influence intensity, and finally performing fuzzy judgment on the emergency traffic flow priority level and determining an emergency traffic flow priority control strategy according to the emergency traffic flow priority level. The fuzzy division method is simple in algorithm, easy to realize, low in resource consumption and high in computational efficiency.

Description

technical field [0001] The present invention relates to the field of intelligent traffic technology, in particular to the field of emergency traffic flow priority control, and more specifically, to a multi-layer fuzzy division method based on emergency traffic flow priority levels. Background technique [0002] Emergency rescue vehicles include ambulances, fire trucks, police cars on duty, municipal rescue vehicles (electricity, water supply, transportation), engineering rescue vehicles and other vehicles that are performing special emergency rescue tasks, which play a key role in emergency rescue operations. It is an important urban emergency service resource, and improving its rescue speed can improve the success rate of rescue. Emergency traffic flow is a special traffic flow composed of emergency rescue vehicles. With the acceleration of urbanization and the growth of traffic demand, the impact of emergency traffic flow on the disturbance of urban traffic system is beco...
