Abstract

The invention discloses a method and a system for calculating average travel time between adjacent bus physical stations based on bus-mounted GPS data. A data acquisition module receives bus GPS historical data for 5 days, a data processing module regards a road section between adjacent bus line stations as a unit, generates a new road section number variable, modifies a data set GPS time data format, and generates a time variable which can be calculated by a data set calculation module; and the data set calculation module firstly calculates the average travel time between two adjacent line stations, then matches two data sets of the line stations and the physical stations, calculates the line station number set as a physical station number, and collects the average travel time between theadjacent physical stations at morning and evening peaks and flat peaks based on the successfully matched physical station number data. According to the method and the system, the effectiveness and accuracy of the bus GPS data can be improved, and the average travel time between the adjacent physical stations at morning and evening peaks and flat peaks can be obtained.

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...
