Abstract

The invention discloses a method and system for calculating the average travel time between adjacent bus physical stations based on the GPS data on board the bus. The road section is regarded as a unit, and a new road section number variable is generated, and the GPS time data format of the data set is modified to generate a time variable that can be calculated by the data collection module; the data collection module first calculates the average value between two adjacent line stations. Travel time, and then match the two data sets of the line station and the physical station, count the line station number set as the physical station number, and based on the successfully matched physical station number data, collect the average journey between adjacent physical stations during morning and evening peaks and off-peak hours time. The invention can improve the utility and accuracy of the bus GPS data, and can obtain the average travel time between adjacent physical stations during morning and evening peaks and flat peaks.

Description

technical field [0001] The invention relates to the technical field of public transportation information processing, in particular to a method and system for calculating the average travel time between adjacent public transportation physical stations based on the GPS data on the bus. Background technique [0002] Global Positioning System (Global Position System, GPS) is a positioning technology developed by the United States. GPS is widely used in the on-board navigation system of public transport vehicles due to its high precision and strong anti-interference ability. With the development of intelligent public transport systems and the promotion and popularization of GPS positioning technology, buses in many cities are equipped with GPS positioning devices, through which a large number of extensive road real-time information can be obtained, including time, location, road section, vehicle speed, etc. data. However, at present, these positioning information are only used f...
