| Outline of Final Research Achievements |
The simulation approach of transportation state is getting popular according to the development of the computational capacity, while more and more data can be available to measure the traffic state. Both approaches have advantages and disadvantages, respectively. So the assimilation of these approaches will give us more useful tool for the estimation of traffic states. In this study, we applied various type of data, such as the cell phone location data, the probe car data, the smartphone acceleration data and the ETC 2.0 data, besides the traditional person trip data. We also constructed the simulation systems that describe the individual travel behavior of one day, the travel mode choice by game situation, the pedestrian behavior and the traffic flow. The assimilation result through our empirical study indicated the efficacy of the proposed approach. As conclusion, we showed the general frame of this approach for traffic survey and management．
