A data acquisition system and method based on a city flow network

Abstract

The invention discloses a data acquisition system and method based on a city flow network. The system comprises a bus real-time and prediction subsystem, a taxi time distribution subsystem, a road pedestrian and non-motor vehicle monitoring subsystem of the city flow network system. The data obtained by bus real-time and prediction subsystem, taxi temporal distribution subsystem, road pedestrian and non-motor vehicle monitoring subsystem are subjected to fitting in space and time, and the temporal spatial distribution map of the city is established with fine granularity. The data of the threeare subjected to fitting in space and time, and the temporal spatial distribution map of the city is established with fine granularity, and then the urban mobile network system is constructed to provide related early warning of the public conflict time.

Description

technical field [0001] The present disclosure relates to the technical field of computer processing, and in particular, to a data acquisition system and method based on an urban flow network. Background technique [0002] In the field of urban transportation in China, the contradiction between traditional taxis and special cars based on the Internet is becoming more and more serious. Emergencies in the taxi industry have become a thorny problem for local government management departments. Emergency early warning of urban transportation and related public events There is a lag in the mechanism. A city’s public passenger transport management service center has also become the first case in China’s taxi industry brought to court by a special car operator. The key is that it is very likely to induce greater conflicts in the whole society. Relying on traditional experience-based management, simple confiscation and post-event contingency plans has been unable to form an effective ...

Problems solved by technology

[0002] In the field of urban transportation in China, the contradiction between traditional taxis and private cars emerging based on the background of the Internet is intensifying. Emergency incidents in the taxi industry have become thorny issues that plague local government management departments. Emergency warnings for urban transportation and related public events There is a problem of lag in the mechanism. A certain urban public passenger transport management service center has also become the first case in the Chinese taxi industry that was brought to court by a special car operator. The key is that it is very likely to induce greater conflicts in the whole society. Relying on traditional experience-based management, simple confiscation and post-emergency emergency plans can no longer form an effective and timely response to related mass emergencies. At the same time, if possible potential emergencies can be mined from a large amount of time series data generated by travel, it will undoubtedly have high theoretical value and practical significance for conflict prevention
