Abstract

The invention provides an acquisition method and device for a crowded area. The method comprises the steps that trajectory data of operating vehicles is acquired, then a staying area of the operating vehicles is obtained according to the trajectory data, and therefore the crowded area can be obtained according to the staying area. Manual participation is not needed, operation is easy, the accuracy rate is high, and therefore the acquisition efficiency and reliability of the crowed area are improved.

Description

[0001] 【Technical field】 [0002] The invention relates to traffic technology, in particular to a method and device for acquiring a crowded area. [0003] 【Background technique】 [0004] With the rapid development of social economy, my country's urbanization process continues to advance, and the number of urban populations is increasing. Urban public transportation, living facilities and other areas often usher in short-term peak flow of people and become densely populated areas. For example, Large-scale gatherings such as concerts and sports competitions. The high concentration of crowds may bring some problems, for example, potential safety hazards and so on. In the prior art, the relevant information of densely populated areas is usually collected manually, for example, the relevant information of large-scale gatherings is collected from relevant departments or specific websites. [0005] However, since it is necessary to manually collect the relevant information of the den...
