Abstract

The invention relates to the technical field of traffic signal control at urban road intersections, and discloses a method for emergency rescue dispatching and dynamic path integration based on bi-level planning, including the following steps: 1), 2), 3), 4), 5), and 6 ), 7), 8). The emergency rescue scheduling and dynamic path integration method based on two-tier planning, by fully considering different priority emergency vehicles and real-time changing traffic environment, and considering the factors that affect emergency vehicle scheduling and dynamic path selection, establishes a two-tier system based on The planned emergency rescue scheduling and dynamic path integration scheme realizes that emergency vehicles can avoid traffic jams in real time, reach the destination quickly, and improve the operating efficiency of emergency rescue. The effect of dispatching and adjusting the optimal route selection problem of emergency vehicles under dynamic road network.

Description

technical field [0001] The invention relates to the technical field of traffic signal control at urban road intersections, in particular to an emergency rescue scheduling and dynamic path integration method based on double-layer planning. Background technique [0002] At present, the urbanization process of most cities in China is intensifying, and the occurrence of emergency emergencies is becoming more and more serious. Therefore, how to effectively combine the dispatching and route selection of emergency vehicles to maximize the efficiency of emergency rescue transportation has become the key to alleviating casualties and property losses in emergency incidents. A powerful method, building an emergency rescue scheduling and dynamic path integration method based on two-level planning, and effective management and control for emergency traffic of different priority levels is a powerful means to reduce the impact of emergencies and reduce the severity of their consequences. ...
