Traffic Characteristics of Shanghai Freight Hub Based on GPS and Mobile Phone Signaling Data
In view of the problems of low sampling rate,high investigation cost and poor timeliness of traditional road freight transportation survey,which is difficult to reflect the continuity and correlation characteristics of the process of freight transportation,based on the time series characteristics of freight traffic flow,this paper proposed the method of GPS matching with road for trucks with 12t and above and the method of using mobile phone signaling data to identify truck drivers.And the structure of the data model and the key steps of the algorithm are given.The results showed that the traffic source distribution,route distribution and vehicle speed characteristics of the freight hub are obtained by the two data analysis methods,which are consistent with the development status of road freight reported in Shanghai traffic operation annual report.The number of truck drivers identified by mobile signaling data is equal to the actual number,and the proposed truck routing algorithm is accurate and practical.It can provide technical support for finding out the utilization of road traffic space in freight hub and improving the level of freight system planning and operation management.
