Problems solved by technology

[0005] The existing way to obtain the bus line track is mainly to directly obtain the bus line track according to one or several operating tracks of the bus. This method is simple and easy and can basically confirm the bus line track in most cases, but due to In many cases, the bus GPS data has a large offset, and it is easy to produce a trajectory that deviates from the station line and does not match the actual line trajectory.

Embodiment Construction

[0051] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0052] Such as figure 1 The illustrated embodiment is a method for extracting bus route tracks based on bus GPS data and site information, comprising the steps of:

[0053] Use the following methods to obtain the route track of the No. 465 bus in Yuhang District, Hangzhou City from Qingshan Station to Yuhang Station. The specific steps are as follows:

[0054] 1) Obtain the station data of all bus lines in Yuhang District, Hangzhou. For any station, if the latitude and longitude is missing on a certain line (that is, the latitude and longitude is 0), but there are normal latitude and longitude on other lines, use the normal latitude and longitude to fill in the missing latitude and longitude; If any station has missing latitude and longitude for all lines, delete the station.

[0055] 2) Normalize the site data filtered in 1), and analyze all...

Abstract

The invention discloses a method for extracting bus route tracks based on bus GPS data and station information, comprising the following steps: obtaining station data of all bus routes in a certain city, preprocessing the station data; performing normalization processing on the station data, The latitude and longitude of all stations are analyzed. If there are more than two latitudes and longitudes of the station, the improved kmeans clustering algorithm is used to cluster the latitude and longitude of the station to obtain a new latitude and longitude of the station. The invention has the characteristics of effectively avoiding the acquisition of the bus line trajectory with obvious offset direction by combining the bus line trajectory obtained by combining the station information and the bus GPS historical data.

Description

technical field [0001] The invention relates to the technical field of bus history GPS data processing and analysis, in particular to a method for extracting bus line tracks based on bus GPS data and station information. Background technique [0002] Smart public transportation is an important direction for the development of urban traffic informationization. Through the construction of public transportation informationization, the convenience and intelligence of public transportation will be improved. Smart public transportation is an inevitable mode of public transportation development in the future, and it is of great significance to alleviate the increasingly serious traffic congestion problem. [0003] The bus GPS data is one of the most important data supporting the construction of smart buses. Although the bus GPS positioning is relatively accurate at present, it is still affected by factors such as terrain, weather, and road conditions in practical applications, and ...
