Abstract

The present invention belongs to the technical field of traffic, and especially relates to a method for achieving vehicle source prediction by calculating an O-D flow based on mobile phone data. The method comprises: a first step of mining position information of mobile phone data; a second step of building a resident travel model based on the mobile phone data; a third step of estimating a motor vehicle travel O-D matrix; a fourth step of predicting urban road vehicle sources of the resident travel model based on traffic demands; and a fifth step of analyzing vehicle source distribution leading to jam based on a vehicle source prediction theory. The method of the present invention can provide faster and more accurate information support for traffic organization and allocation, and provides an economic and feasible new method for traffic demand prediction.

Description

technical field [0001] The invention belongs to the technical field of traffic, and in particular relates to a method for calculating O-D flow based on mobile phone data to predict vehicle sources. Background technique [0002] Facing the serious contemporary urban traffic congestion, the level of urban traffic planning and organization has attracted widespread attention. Traffic demand is an important basic data for traffic planning and organization, and its acquisition method has always been a very important direction of exploration. Because the traditional traffic demand forecasting method consumes huge manpower and material resources, using various information resources for data mining, analyzing and obtaining traffic demand has become a new research direction. In the prior art, the basis of vehicle source prediction is O-D flow prediction. Traditional O-D flow investigation and analysis methods consume huge manpower and material resources. With the increasing complexit...
