| Summary: | 碩士 === 國立臺北科技大學 === 土木與防災技術研究所 === 90 === Most of the developed countries develop their cities by planning city development plan first， second build the city according to the plan。However the development of Taiwan’s major cities is a result of people gathering under a natural comfortable living environment without any pre-existed plan 。 Due to the city development differences between Taiwan and other developed foreign countries and Taiwan is located rightly on the Philippine Continental earthquake strap and Taiwan possess the characteristic of typhoon-climate ， Taiwanese people treat natural disasters as common phenomena。 Because of this reason， the rescue activities and plans are much different from major developed cities， also the traffic volume、 route and its traffic management system compared to the usual situation。
The purpose of this paper is that a disastrous rescue model for the unique situation of Taiwan cities is developed and its disastrous rescue route is also predicted by this model。 First the different types of natural disasters that Taiwan has experienced in the past are discussed in this paper。Then according to city traffic volume and the theory based on the conventional sequential overall transportation demand model ，the ratio between public and private modes and the total travel time are investigated in TransCAD software 。The value of the saved time is obtained from the higher ratio of public modes，and this value will approach a convergent data 。By transportation equilibrium concept a city optimal transportation model in theory is assigned。Hence the trip generation nodes planning a range of 500-meters pedestrian availability are achieved ；and the trip generation model is produced by the priority order of entering the disastrous area。It is also possible to have parks、 schools and administrative offices acting as shelters for people in the hazardous area； hospitals as places for the wounded people，fire engineer as the official representative。 Considering the rescue distance and road-hindrance factors the collection data is input to TransCAD and the rescue transportation demand model when the disaster happens is achieved。The most suitable rescue route is chosen by the simulating the total travel time and rescue routes in disastrous area 。Also another suitable rescue route is obtained in TtransCAD calculation by the total travel time and public modes in simulation under the transportation equilibrium concept 。 From the total travel time difference between the above two models and it will be a referent index for authorities that set up a rescue method and move the public modes by law when the disaster is happened in future。
