Method for bus origin-destination (OD) investigation by using mobile phone base station data and operating vehicle global position system (GPS) data

Abstract

The invention provides a method for bus origin-destination (OD) investigation by using mobile phone base station data and operating vehicle global position system (GPS) data, comprising the following steps: 1) collecting mobile phone positioning data and bus GPS data; 2) transferring the mobile phone positioning data into travel information of users; 3) extracting characteristic values from the travel information of the users; 4) analyzing the extracted characteristic values to obtain basic travel characteristics; 5) matching bus travel information with the bus GPS data to obtain bus travel characteristics; and 6) carrying out statistical process on the obtained travel characteristics, and then outputting a population travel characteristic report form. The method is based on the mobile phone positioning data and the bus GPS data and then is used for performing a series of processes on the mobile phone positioning data and the bus GPS data, thereby automatically obtaining a high-quality, high-fineness and large time-span population travel characteristic reform form from a great amount of data, intelligently acquiring the population travel characteristics, reducing manpower and material resource consumption and improving the accuracy and effectiveness of the investigation.

Description

technical field [0001] The invention relates to the field of investigation of traffic trips, in particular to a method for investigating public transport OD. Background technique [0002] The public transport OD survey is the survey of the starting and ending points of public transport, which refers to the traffic volume between the starting and ending points. "O" comes from English ORIGIN, pointing out the starting point of the trip, and "D" comes from English DESTINATION, pointing out the destination of the trip. Bus OD traffic survey usually uses statistics, actual measurement, analysis and judgment to grasp the development trend of traffic status and the working process of related traffic phenomena, mainly including traffic flow element survey, traffic travel survey, traffic accident survey, traffic environment survey and other types. [0003] At present, high-tech such as automatic instrument measurement method has been widely used in traffic flow investigation, which ...

AI Technical Summary

Problems solved by technology

These methods not only consume a lot of manpower and material resources, but also the survey results are limited by the technical level of the investigators, the degree of cooperation of the surveyed personnel and the coverage of the survey, and the accuracy and effectiveness of the results are not high.

[0004] However, the existing intelligent survey technologies, such as the technologies mentioned in "Modeling Method of Population Spatio-temporal Dynamic Travel Characteristics Based on Multi-source Data Fusion" (Patent No. 200910190637.0), either need to input map data, or need the user's GPS information. The amount of data is large, processing is difficult, the representativeness of data samples is insufficient, and the information obtained on bus travel is not detailed enough, etc.
