191 Abstract Younshik CHUNG et al. The ultimate goals of studies and activities conducted by the transport sector are to improve the quality of transportation services and the accessibility to transportation systems and also to maintain public safety, good environment, and positive and balanced area development. To achieve these goals, the road transport sector tries to build roads that link the important areas and to let the drivers take advantage of the roads without any constraint. However, the frequent traffic accidents and road constructions and occasional collapses of a bridge often impair the basic function of the roads, ultimately creating negative impacts on road uses. In general, the negative effect, inconvenience, and risk related to the use of transportation systems are associated with transportation vulnerability. Recently increasing is the concern for vulnerability issue, particularly after the earthquake in Kobe in 1995 and the
192 September 11 terrorist attack in New York City in 2001. In addition, the traffic systems became more vulnerable with the recent volcano eruption in Iceland (April 2010, May 2011) and Northeast earthquake and tsunami in Japan (March 2011). Unexpected weather changes, both domestic and foreign, that result in extreme snowfall and rain are increasing in frequency, scale, and severity. These external impacts lead beyond mere traffic congestion to transportation disasters such as loss of roads and bridges, landslides, slope collapses, flooding, and regional isolation, damaging transportation facilities and inflicting serious casualties. Although the natural disasters cannot be prevented, early community recognition, management, and preparation for them will minimize the scale of damage. Therefore needed are the efforts to categorize the vulnerability ranges depending on the types of disasters. Meanwhile, the interest in qualify traffic information is growing with the development of technologies related to real-time traffic information collection, processing, and dissemination. Especially, needs for and questions about the near future traffic situation are now prominent. The currently available real-time traffic information has formed the archived traffic data, making it possible to extract the information patterns on general traffic situations. It is commonly believed that the spatio-temporal traffic patterns tend to persist unless there are traffic incidents such as traffic accidents, public events, protests, road construction, and adverse weather. Therefore, it is possible to provide the traffic forecasts that predict traffic conditions in the near future based on the archived data. As traffic conditions are influenced by a variety of incidents, the existing traffic patterns may be changed by such incidents as road construction, traffic accidents, public events, and protests around the
193 roads. Most of the events, except for traffic accidents, are predetermined or predictable and can be identified in terms of time, location, and type. Therefore, when a set of information about weather, road construction, public events, and protests are properly combined and orchestrated, it is possible to provide predicted traffic information for drivers. Based on foregoing, this study formulates the assessment indexes of traffic vulnerability related to traffic congestion, trafficability, road landslide, and road flooding, and presents the measures to build effective traffic forecast systems and to reduce vulnerability in the transport sector. The study also offers the measures to build traffic forecast systems by combining such data as archived traffic data, weather condition, public events, protests, and road construction. Development of traffic forecast systems can provide the drivers with quality forecast service and support the operators of the roads in establishing plans to improve the road facilities and to block the roads according to vulnerability degree. Lastly, to analyze the needs for and responses to traffic forecast information, a survey was conducted with 600 drivers. Based on the results of the survey, the measures for establishing traffic forecast systems are proposed.
