Abstract -- The highway system is an key channel for transportation and civil activities. Its destruction caused by disasters will lead to grave impacts on communication, emergency rescue and aid delivery, inhibiting the progress of rescue missions.
This is a two-year research. The second year research continues the agenda set in the first years in collection, analysis and integration of relevant information and go further to the planning of disaster prevention system suitable for Taiwan. The key goals are to set out an emergency rescue and recovery strategy for highway, devise a comprehensive method for diagnosing and retrofitting damaged highway and formulate recovery techniques and the timing of its application. In conjunction with the inundation and debris flow simulation as well as reliability analysis of HAZ-Taiwan, developed by NCREE, the most likely damaged section of the highway can be analyzed, the optimal route for aid delivery can be found and the planning of emergency substitute roads can be carried out for facilitating the timely arrival of rescue teams, machines needed and emergency aid. The results of the simulation then are fed back to the current system (including laws, organizations and operation plans) for finding points of improvement with the hope that our highway system can be well planned and managed before disaster, equipped with responsive mechanisms during the hazard, and excellent recovery ability after the catastrophe. With this system in place, the damages of the highway system resulting from the hazards can be mitigated to the minimum.
