Abstract

The invention discloses a dynamic path planning method for emergency vehicles based on a rolling time domain in a networked environment. In an intelligent networked environment, after an automatic driving vehicle receives an emergency rescue task, it first uses the A* algorithm according to the V2V and V2I communication technology Plan the initial path, then use the idea of ​​model predictive control rolling time domain to dynamically plan the path selection of emergency vehicles, and use V2I technology to provide signal priority coordination for the intersection signal lights on the emergency vehicle driving path to ensure emergency rescue vehicles to carry out emergency rescue Safety and efficiency during missions.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a dynamic path planning method for emergency vehicles based on rolling time domain in a networked environment. Background technique [0002] Emergency route planning is an important scientific and technological issue in emergency rescue and evacuation work. Due to the constant changes in information such as traffic flow on the road network, in the planning of long-distance routes, the emergency route needs to be dynamically adjusted and the corresponding phase strategy of signal priority is determined based on this. . [0003] The path planning algorithm in the traditional environment assumes that the traffic state of the road network is static, that is, the travel time of the vehicle on the road section does not change with the change of the traffic state of the road network, and the starting and ending points are fixed. Driving time, road resistance is calcu...
