Abstract

The invention discloses a computer recognition method of GPS (Global Positioning System) positioning-based transportation mode combined travelling. The method comprises the following steps of: acquiring data information such as travelling point and space tracks, instant speed and longitude and latitude of combination of multiple travelling modes of a traveler by using a GPS mobile positioning technology; carrying out mode recognition on the combination of multiple travelling modes by adopting data mining methods such as a BP neutral network through combination of a GPS technology and a GIS (Geographic Information System) technology, extracting information including geographic locations of a travelling time point, a travelling mode change time point and a transformation point of the traveler, and finally researching and developing one set of complete recognition and acquisition method which is suitable for the travelling of the combination of the multiple transportation modes in large cities in China.

Description

technical field

[0001] The invention relates to computer identification technology, in particular to a computer identification method for combined travel of traffic modes based on GPS positioning. Background technique

[0002] At present, the data collection of residents’ traffic travel behavior mainly uses traditional questionnaire surveys, telephone interviews, email interviews and other methods, but there are many problems in obtaining personal travel behavior characteristic data in traditional travel survey methods of residents: 1) subjective recall is usually used in manual questionnaire surveys The problems of deviation and error are relatively common, and the randomness is too strong, so it is difficult to fully guarantee the accuracy of the data. In traditional questionnaire surveys, respondents need to recall detailed travel data such as travel time, travel routes, travel methods, and travel destinations. The workload of respondents is heavy, and the burden of recal...
