Taiwan is located in the Circum-Pacific seismic zone, and thus facing earthquake disaster will be inevitable. To handle losses from disaster, disaster risk assessment and management are getting more and more important and be regarded as a fundamental tools for developing risk reduction.
The assessment of spatial and temporal dimensions is an important part for disaster risk management, but it has been disregarded or presumed to be static(ex. population exposure) because of the difficulty of data collection or spatial-temporal modeling. In order to assess disaster risk more precisely, the simulation of earthquake impact will be calculated with Taiwan Earthquake Impact Research and Information Application Platform (TERIA), and cellular data will be used as population trajectory to measure traffic corridor exposure at spatial and temporal dimensions in this paper.
The purpose of this paper will be (1) Interpolation of cellular trajectory data with Catmull-Rom Curve to measure the trajectories continuously. (2) Calculation of trajectories density in each raster cells with kernel density. (3) Simulation of earthquake impact with TERIA to measure the passing failure probability of road network. (4) assessment of earthquake disaster risk in every hours, and discuss the difference between day and night, and normal day and week day.
