Analysis System of Data Fusion for Traffic Management in Disaster and Normal Situations

Abstract

In this research, we suggested an improved method of constructing database for data fusion of mobility, disaster, externals etc. And analysis system of the data fusion was developed using the database for creating information for traffic management in disaster and normal situations. We built an evacuation simulation as one example of data fusion analysis system. Not only network and OD data but also population and tsunami data were used as inputs. The Great East Japan Earthquake was simulated and analyzed traffic flow. Road and shelter capacity /location were evaluated using the simulation results.
