Method for acquiring public transportation trip chain using mobile phone GPS and electronic map data

Abstract

A method for obtaining public transportation trip chains using mobile phone GPS and electronic map data. Based on the idea of ​​identifying the overall mode chain of public transportation, public transportation trips are judged as multiple segments. There are N transfer points for one public transportation trip. The travel mode of each segment is different, and the method of identifying the travel mode of each segment is also different. First, identify a trip, then identify the main mode of transportation, then identify the transfer point, and finally identify the connecting mode of transport; judge Exit the transfer point, and then judge the connection method according to the speed before the transfer point. So as to achieve the effect of accurate and effective discrimination.

Description

technical field [0001] The invention relates to an acquisition method of a public transportation trip chain. Background technique [0002] The travel mode survey is an important part of the urban traffic survey. The current mobile phone positioning survey method often simplifies the travel mode of a trip into a single travel mode. For example, a trip that takes the subway is treated as a single subway trip. Traveling by bus instead of subway is treated as a single bus trip. However, public transportation often uses one or more transfers, and the connecting transportation mode is often neglected in the current survey. The study of convenient feeder transportation can expand the accessibility of public transportation has also received more and more attention. [0003] Patent (CN105608505A) is to identify a single rail transit mode through signaling data; patent (CN104751631A) is to identify traffic modes through mobile phone positioning data, first identifying non-motorized ...
