Problems solved by technology

[0004] There are many shortcomings in the traditional emergency evacuation method: the input data of commonly used evacuation simulation systems - population distribution data, mostly based on static demographic data
Therefore, if you just use static demographic data as the data basis for evacuation simulation, it is obviously unscientific

Embodiment Construction

[0036] The real-time urban emergency evacuation simulation method and system of the present invention will be further described below with reference to the accompanying drawings.

[0037] Now that the share of mobile phones has reached a relatively high level, it is possible to boldly introduce mobile phone communication location data to solve the problem of demographic data. Although it is still impossible to accurately determine the specific location of each person, the distribution characteristics of the population at different time periods will be obtained through the study of the probability statistics of mobile phone communication location data and the characteristics of location change trends.

[0038] Most of the existing emergency evacuation simulation systems are based on AI (Artificial Intelligence). The advantage of this method is that it can maximize the simulation of some characteristics of individual personnel (such as age, personality, gender, etc., because the...

Abstract

The invention discloses a real-time city emergency evacuation simulating method based on mobile phone data. The method comprises the steps: 1) obtaining geographic information system (GIS) map information by using a GIS map information sub-system; 2) calculating personnel real-time distribution information by using a personnel real-time distribution mining sub-system through the mobile phone data and the information obtained by the GIS map information sub-system; 3) after determining the disaster type, class and affected geographic position, using an affected area judgment sub-system to mark an evacuation site as the evacuation terminal point of all persons; 4) according to the obtained GIS map information, personnel real-time distribution information and disaster area judgment information, calculating a personnel evacuation route and an evacuation scheme of all persons by using an evacuation simulation sub-system. The population dynamic distribution point is obtained by a mobile phone communication data mining method. The method is combined with the city evacuation simulation for obtaining the population situation of whole city before the evacuation. The scientificity and accuracy of the city evacuation simulation are ensured, and the effective basis is provided for the following evacuation scheme.

Description

technical field [0001] The invention relates to the field of urban emergency evacuation, in particular to a real-time urban emergency evacuation simulation method and system based on mobile phone data. Background technique [0002] The emergency evacuation simulation system mainly simulates the evacuation scene of large-scale crowds in a certain emergency situation (natural disaster or man-made disaster). It aims to simulate the real situation, and then predict the occurrence of various situations, and accordingly propose a reasonable evacuation plan to help reduce the loss caused by the disaster. Compared with traditional fire drills, this method can reduce human and financial losses, and can be carried out in a wider area. [0003] The content involved in traditional emergency evacuation mainly includes traffic guidance for people on congested roads, ambulances, distribution of emergency supplies, evacuation signs, SMS guidance evacuation and other methods. [0004] Ther...
