Abstract

The invention provides a mobile phone positioning data-based traveling origin-destination (OD) matrix acquisition method, which is characterized by comprising the following steps of: determining a traffic zone division scheme of a certain road net area; acquiring all the mobile phone positioning data of all traveling groups in a certain time range in a specified road net range in the road net area; performing displacement state judgment on each position point of each traveler; obtaining origins and destinations of each traveler in the travel of each time in the certain time range; and mappingthe origins and destinations onto corresponding traffic zones and performing grouping counting on all identified travel behaviors to form original traveling OD matrix data. The method has the advantage that: the traveling OD matrix data in a large city road net range can be automatically acquired with low cost and high frequency fully based on conventional mobile communication network resources by utilizing positioning information in a conventional mobile phone communication network.

Description

A method for obtaining travel OD matrix based on mobile phone positioning data technical field The invention relates to a travel OD matrix estimation method based on mobile phone positioning data, which is used for high-frequency and automatic acquisition of travel OD matrix data, and can serve traffic planning, traffic demand management policy evaluation and formulation, and traffic management work, belonging to traffic The technical field of planning and traffic demand management. Background technique For the needs of transportation planning, the entire urban road network area is divided into several sub-regions according to factors such as administrative divisions, geographical and hydrological characteristics, and socio-economic properties, and each sub-region is called a traffic district. The travel of urban residents occurs between different traffic districts. The number of trips between any two traffic areas is counted to form a numerical matrix, which is called th...
