Real-Time Road Disaster Information System
Defining Issue: The road conditions in the Chiba prefecture are greatly affected by the frequent and strong typhoons resulting in flooded roads and landslides, and thus the traffic flow becomes almost impossible. Under such disastrous situations, the prefecture's main office lacks accurate information about the inaccessible roads and their conditions from the rest of the sixteen zonal offices. GIS Solution: In order to resolve the problem, the PASCO Corporation and the prefecture are cooperating to develop a road disaster information system (RDIS) to exchange information and manage the destroyed roads utilizing GIS on a real-time basis. Methodology: The main system is provided with workstation ArcInfo facilities and the remaining zones are linked by a wide area network (WAN) through PC ArcView using a client-based system. This network allows each of the zones to access real-time road condition data from the main system. The main system is an integrated system of the technical client server, wireless
transferring of the disaster information, and GIS. The main office receives the disaster information from the sixteen zonal offices and manages their information on a real-time basis. The zonal offices gather and verify the information of the affected neighboring areas on a real-time, as well. This system manages two types of maps utilizing ArcInfo: maps highlighting the affected roads and detours on 1:25,000-scale and maps verifying roads affected by the disaster on a 1:500 scale. Software: The system is mainly based on ArcInfo, ArcView, and Visual Basic software. The RDIS will provide Chiba prefecture with timely and accurate information that will help officials better manage affected roads during and after disasters (e.g., Kobe's earthquake.)
