Embodiment Construction

[0051] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0052] The preferred embodiment of the present invention provides a processing method for route selection, which is used to find the best route from the traffic network according to the starting point and the disaster relief destination point after a disaster. After sudden disasters, such as earthquakes, mudslides, etc., the most fundamental problem that needs to be solved in emergency rescue is how to quickly, safely and efficiently transport emergency relief materials to the disaster-stricken point, and evacuate the victims from the disaster-stricken area and send them to a safe zone , so as to achieve the purpose of reducing casualties and property losses. Therefore, in sudden disasters, when selecting the route of emergency rescue vehicles, it i...

Abstract

The invention discloses a processing method and system for path selection. The processing method comprises the steps that a path optimization model is established, wherein the path optimization model comprises objective functions of journey time, objective functions of transportation cost and objective functions of safe-passing probabilities of all road segments; effectiveness conversion is performed on all the objective functions according to the multi-attribute decision theory, and the maximum values and minimum values of the journey time, the transportation cost and the safe-passing probability of all the road segments are respectively figured out; time utility values, transportation cost utility values and safe-passing probability utility values of all the road segments are determined through linear transformation; the time utility value, the transportation cost utility value and the safe-passing probability utility value are respectively converted into corresponding dimensionless values through dimensionless processing; path optimization is converted into a single-attribute decision by performing weighting on all the dimensionless values; a passing path with the maximum decision utility value is found by the adoption of the shortest-path optimization algorithm. According to the processing method and system for the path selection, the process of the path selection is simplified, and the transportation requirement of emergency relief supplies can be fully met.

Description

technical field [0001] The present invention relates to the field of transportation, in particular, to a processing method and system for route selection. Background technique [0002] The urban road traffic system is an important part of the city's complex giant system, which directly affects the economic development of the entire city and the daily activities of residents. The urban road traffic network is complex and intertwined. When an earthquake disaster occurs, different degrees of road damage and collapsed buildings covering the road will seriously affect the traffic capacity of the entire road network, thereby reducing traffic efficiency. When an earthquake disaster occurs, it will not only cause direct economic losses, but also cause serious indirect losses if the rescue work is not timely. Therefore, the optimal route selection is a key issue in emergency relief. [0003] The current conventional route selection model is to select an appropriate driving route for...
