| Outline of Final Research Achievements |
In this study, we developed a data fusion type survey method by integrating multiple databases utilizing home based web survey. Specifically, we examined seasonal fluctuation by integration with existing net flow survey, and demand estimation by integration with GPS big data of mobile phone.
As a result of the analysis, it was somewhat difficult to explain the differences in the OD table by adjusting the individual attributes, especially for the railroad samples. In particular, consideration must be given to the frequency of trip occurrence by each origin. Furthermore, when cellular phone location information is used for traffic demand survey as an alternative method to existing surveys, it is necessary to acquire data over a period of several days or more to ensure the stability of the estimation result.
