Index inquiry system and method for running information of regional urban buses

Abstract

The invention discloses an index inquiry method for running information of regional urban buses, and belongs to an intelligent traffic technology. The index inquiry method comprises the following steps of: acquiring urban bus station data and bus global positioning system (GPS) data, and removing ineffective data from the bus GPS data; performing logic hierarchy division on urban bus stations to obtain an index tree comprising all stations, and generating a corresponding index sequence for each station; adding index fields to the urban bus GPS data according to regions where the urban bus GPS data are positioned according to the index sequence information; and supplying an inquiry interface to a user, and searching data according to an inquiry condition and the index sequences which are input by the user on the inquiry interface, and returning inquired vehicle information to the user in the form of a file. The invention also discloses an index inquiry system for the running information of the regional urban buses. By the method and the system, the time and space characteristics of bus traffic vehicle data are considered; and the method and the system are particularly suitable for extraction of regional urban bus data.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to an index query system and method of regional urban public transportation vehicle operation information. Background technique [0002] With the rapid development of intelligent transportation (ITS) technology, the accompanying data volume of public transport is huge and growing rapidly, and the continuity cannot be guaranteed in time, and the data is scattered in space. If traditional data storage and management methods are used, It will inevitably lead to a reduction in the efficiency of data processing and affect the application performance of the data. Bus GPS data itself has significant temporal and spatial characteristics, and the analysis of regional bus traffic conditions and the release of regional bus distribution information are all based on regional data retrieval, but traditional data retrieval methods are not based on data. Features are...
