An Introduction to the Spatial-Temporal GIS 'DiMSIS-Ex' and its Application for the Recovery and Restoration Process after Large Disasters in Düzce City: Construction of the New Residential Area and Traffic Network
2013
To contribute to the improvement of regional safety, we have developed a spatial-temporal information system under the concept of a risk-adaptive regional management information system (RARMIS). This system can be characterized as follows: (1) Coordination between normal and emergency functions. (2) Integrated database for handling spatial-temporal data. (3) Implicit topological data descriptions. In this paper, technical matters about spatial-temporal GIS and its applicability for not only disaster prevention but also a broader kind of analyses and the daily tasks of local governments will be explained at first. Then, the case study of Duzce city will be mentioned as an example of the application of spatial-temporal GIS. Relatively soon after the earthquake, it was decided to develop a new residential area in the suburbs of the city and let 50,000 people emigrate there. However, because the road conditions were not so good, we tried to check whether the traffic capacity of the roads between the new residential area and the city center was adequate. Concretely, we surveyed traffic volumes and found that while no serious traffic jams occurred the trip took about 45 minutes. Accordingly, we suggested a new trunk road was needed and also, using vacant lots in the center of the city, small but numerous parking lots might be constructed. At the time of writing, this work has been completed almost according to our suggestions. Now, both areas are connected by a new 8 km-long trunk road and the trip takes only 6 minutes.
