Embodiment Construction

[0037] In this embodiment, a large-scale event at Huanglong Stadium was used as the experimental object. Huanglong Stadium was used as the venue for the large-scale event. The number of people participating in the event reached 30,000, of which 20,000 people chose public transportation as the crowd participating in the evacuation. The experimental environment is as follows: Intel quad-core 2.50GHz processor, 8GB RAM, Window7 system, programming language: Python. The method for rapid evacuation of large and dense crowds based on shared bicycles includes the following steps, see figure 1 :

[0038] 1. Analyze the sites near sites with large and dense crowds and predict the flow of people;

[0039] Step (1-1) After inspecting the road conditions around the Huanglong Stadium, determine the location suitable for deploying bicycles as the starting site.

[0040] Step (1-2) Obtain all public transport stations near Huanglong Stadium. Destination stops are filtered based on the cap...

Abstract

The invention relates to a large-scale dense crowd rapid evacuation method based on a shared bicycle. The method comprises the following steps: firstly, analyzing stations near a site with large-scaledense crowds, positioning a starting station, screening out a destination station, determining the people stream attraction capability of the destination station according to the transport capacity of the destination station and the distance between the destination station and the starting station, and predicting the people stream guidance; using an improved K-Means clusting alograithim to dividea destination site into a plurality of clusters. and finally, the scheduling path of the scheduling vehicle of each station in the cluster is optimized. According to the method, people can be evacuated faster at the initial stage by deploying the bicycles, the riding rate of people is increased through the station clustering algorithm and the dispatching vehicle dispatching algorithm, the crowd evacuation time is shortened, the effect of evacuating the crowds is effectively achieved, and the safety of large-scale dense crowd places is improved.

Description

technical field [0001] The invention relates to the technical field of public transport guidance, in particular to a method for rapid evacuation of large and dense crowds based on shared bicycles. Background technique [0002] With the development of China's economy and the improvement of people's living standards, more and more large-scale events are held in cities. Large-scale activities are characterized by large numbers of people and high concentration. If the crowd cannot be evacuated quickly, it will cause congestion and even a stampede. [0003] At present, most of the methods related to crowd evacuation analyze the action rules of the crowd after the event is over, and construct the dispersion model of the crowd in space and time according to the rules for research, but have not proposed a complete plan to evacuate the crowd. Therefore, how to quickly evacuate dense crowds is still an urgent problem to be solved. With the rise of green travel, more and more people ...
