Embodiment
[0021] Such as figure 1 As shown, the present invention provides a travel OD matrix acquisition method based on mobile phone positioning data, and the values of various threshold parameters involved in this embodiment are shown in Table 1.
[0022] threshold symbol value dimension T min 10 Second Tmax 15 minute V min 1 km / h Lmax 1000 rice Tstill-min 15 minute
[0023] Table 1
[0024] The concrete steps of the method provided by the invention are:
[0025] Step 1. Determine the division plan of the traffic area. The division plan of the traffic area is a kind of area division scheme implemented for the entire road network area according to the administrative division, geographical and hydrological attributes, land use properties and road distribution. It can be obtained from relevant traffic planning. directly obtained by the government management department;
[0026] Step 2. Preprocessing of mobile phone positioni...

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 mapping the 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
technical field [0001] 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 [0002] 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 the OD matrix of residents' trips. Resident travel OD matrix refle...
