AN EVALUATION MODEL OF MEDICAL TRANSPORT WITH TSUNAMI EARLY WARNING SYSTEM

The Japanese Central Disaster Management Council announced a new damage estimate in the event of an earthquake with its epicenter in the Nankai Trough. The estimate shows the huge human damage. However, they mentioned the possibility of minimizing the casualty count by constant preparation for prompt evacuation to higher places in the event of a tsunami. This study aims to develop a reliability analysis model for medical transport activity considering a tsunami risk. The model includes a risk evaluation model developed to evaluate medical transport activity when a tsunami early warning system can be used. By applying it to Chita Peninsula in Japan, it is demonstrated that the proposed model effectively implements the evacuation and medical transport planning. Some proposals are given for the road network in the area.

TSUNAMI-GENERATION WARNING SYSTEM USING EARTHQUAKE EARLY WARNING

We propose early-warning system for reducing tsunami refuge using the data of the magnitude and the depth informed by the Earthquake Early Warning (EEW) by Japan Metrological Agency (JMA). The EEW provides advance announcement of the estimated seismic intensity and expectSed arrival time at the just points and regions before arriving strong motion. The hypocenter and magnitude of the earthquake are estimated by using wave form data observed by seismographs near the epicenter. Inukai et al. (2009) proposed the method to determine whether generate tsunami using scaling relation between magnitude and depth of hypocenter. The probability of tsunami generating is calculated by using the EEW information (magnitude and depth) and the Inukai’s scaling relations. In this method, the information of probability of tsunami generating is issued in a few seconds after EEW. We incorporated this method into our system and verified validity of our system.

Risk management of real-time earthquake information system for construction filed

Recently, a real-time earthquake information system has been developed for railway companies, education facilities, manufacturing businesses, and in other public and private sectors. The system provides an alarm and various security controls to facilitate a persons safety a few seconds before an earthquake occurrence. The risk mitigation of such a real-time earthquakeinformation system for the construction field is discussed through a questionnaire survey of construction managers. According to the results of the survey, the system is expected to decrease certain risks. We suggest the following points to be important: 1. A discussion for countermeasures until earthquake occurrence is required. 2. The cost-benefit balance of the system is debatable.

Study on Signal Priority Systems for Vehicles in Emergency Dispatch

Abstract Our purpose is to clarify the efficiency of a signal priority system by the simulation model based observation. The signal priority system is expected to shorten dispatch time and assure the safety of the emergency vehicle. From a case study, it becomes clear that signal priority system is helpful for smooth dispatch of the emergency vehicle, and that the detector position and blank time affect the efficiency of the signal priory system.

Train operation with arranging conflicts between commuters and travelers in railroad transport to and from a metropolitan airport

Existing railroad lines for commuters and shoppers are sometimes used for access to an airport from a metropolitan area. If express trains run on such a line, conflicts arise between the convenience of regular users and airport users. This study considers how to operate trains in order to resolve the conflicts in railroad services to and from an airport. We first interview commuters on factors such as fares, congestion, speed, frequency, and choice of type of train, and formulate a discrete choice model for commuters with respect to a line to Chubu International Airport (under construction). Discrete choice models are certainly useful for explaining individual choice behavior but mutually affecting behavior is not revealed explicitly. Then, we make an aggregate analysis of train choice for the two types of users. The results suggest how to provide a fair and efficient service on the airport railroad line.

RISK EVALUATION OF TRANSPORT ACTIVITY FOR THE INJURED AT A SERIOUS INCIDENT

Transportation for the injured is one of the important countermeasures at the scene of a serious incident, but it has never been handled in a serious incident prevention plan. This paper aims to evaluate the risk of those who are injured when a serious incident occurs. Three kinds of risks for the injured are defined: the transportation risk; the medical confusion risk; and the left behind risk; each of these is evaluated through the development of s simulation model.
