Embodiment Construction

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

[0027] The embodiment of the present invention aims at the user's regional bus data needs, combines the time and space characteristics of the bus data, and proposes a spatial data retrieval model based on the feature area, and obtains a method for indexing the bus data based on this model. The indexing method facilitates the retrieval of moving object data within the feature area. It is different from the service requirement that the index query for the information of the moving object in the prior art is based on a road section or a line as a unit or an evenly divided grid as a unit.

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

[0029] Basic point object: take the location point where the bus stops in the city are located as the b...

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 for regional urban public transportation vehicle operation information. Background technique [0002] The rapid development of intelligent transportation (ITS) technology has resulted in a huge amount of bus data and a rapid growth rate, and the continuity in time cannot be guaranteed, and the data is scattered in space. If traditional data storage and management methods are used, It will inevitably reduce the efficiency of data processing and affect the application performance of data. Bus GPS data itself has significant time and space characteristics, and the analysis of regional bus traffic conditions and the release of regional bus distribution information are based on the premise of regional data retrieval, but traditional data retrieval methods are not based on data. Features are used as the basis for storage,...
