Emergency rescue scheduling and dynamic path integration method based on double-layer planning

Abstract

The invention relates to the technical field of urban road intersection traffic signal control, and discloses an emergency rescue scheduling and dynamic path integration method based on double-layer planning, which comprises the following steps: 1), 2), 3), 4), 5), 6), 7) and 8). According to the emergency rescue scheduling and dynamic path integration method based on double-layer planning, emergency vehicles with different priorities and real-time changing traffic environments are fully considered, and on the basis of considering factors influencing emergency vehicle scheduling and dynamic path selection, an emergency rescue scheduling and dynamic path integration scheme based on double-layer planning is established; the emergency vehicles can avoid traffic jam in real time and quickly arrive at destinations, the emergency rescue operation efficiency is improved, meanwhile, the method has real-time performance and flexibility, and the effect that the optimal path selection of the emergency vehicles can be adjusted according to scheduling of different types of emergency vehicles and under a dynamic road network is achieved.

Description

technical field [0001] The invention relates to the technical field of urban road intersection traffic signal control, in particular to an emergency rescue dispatching and dynamic path integration method based on bi-level 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 emergency vehicle dispatching and route selection to maximize the effectiveness of emergency rescue traffic has become the key to alleviate emergency casualties and property losses. A powerful method, the construction of emergency rescue scheduling and dynamic path integration methods based on two-tier planning, and effective management and control of emergency traffic with different priorities are powerful means to reduce the impact of emergencies and the severity of their consequences. [0003] Most of the current emergency ...
