Embodiment Construction

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The embodiment of the present invention proposes a spatial data retrieval model based on a characteristic area in response to the user's regional public transportation data requirements, and combines the time and spatial characteristics of the public transportation data. Based on this model, a method for indexing public transportation data is obtained. The index method is beneficial to the retrieval of moving object data in the feature area. It is different from the prior art, which is different from the business requirements that the index query of the mobile object information takes the road segment or the line as the unit or the evenly divided grid as the unit.

[0028] The related concepts in this embodiment are explained as follows:

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...
