Traffic evacuation method and traffic evacuation system for large-scale events

Abstract

The invention discloses a traffic evacuation method and a traffic evacuation system for large-scale events. The method comprises the following steps: acquiring the location information of the start point of evacuation, the location information of the end point of evacuation and the total number of vehicles to be evacuated; equally dividing the vehicles to be evacuated into multiple parts, calculating the travel time of each section between the start point of evacuation and the end point of evacuation, and evacuating the first part of vehicles to be evacuated P1; determining effective sections, and calculating the section edge weight, distribution rate and distribution volume of each effective section; calculating the sum of distribution volume of the sections, and updating the travel time of each section between the start point of evacuation and the end point of evacuation according to the total traffic volume of the sections; and re-determining effective sections connected with an evacuation node according to the updated travel time of each section, calculating the section edge weight of each effective section, and evacuating the next part of vehicles to be evacuated. Vehicles are reasonably distributed to sections according to the traffic condition of the sections. The unreasonable phenomenon that the traffic flow is all on the shortest path due to single-path distribution is overcome.

Description

Technical field [0001] The invention relates to a method and system for traffic diversion of large-scale activities, belonging to the field of traffic diversion. Background technique [0002] The evacuation of large-scale event vehicles often causes traffic jams within a certain range and affects normal traffic. Therefore, the effective evacuation of large-scale event vehicles is particularly important. However, the existing technology often fails to achieve the desired effect for large-scale event evacuation. Due to the irrationality of the evacuation method in the prior art, it is still unable to effectively solve the problem of traffic jam caused by large-scale moving vehicles. Summary of the invention [0003] Objective of the invention: In order to effectively solve the problem of traffic jam caused by large-scale activity vehicles, the present invention provides a large-scale activity traffic guidance method and system. [0004] Technical solution: In order to achieve the abo...
