英文摘要：

Focusing on the planning, design and management of urban transportation systems capable of disaster prevention and relief, this paper analyzes the impacts of natural disasters on cities and their transportation systems, and introduces the fundamental concepts of disaster, disaster-prevention,-relief, and-reduction, as well as urban/transportation lifeline. To meet the transportation needs both in normal time and during disaster periods, the paper elaborates the key tasks in the planning, design and management of a transportation system tailored for disaster relief in light of ideas and theories of disaster relief. Particularly for urban transportation system management in disaster relief, the paper proposes a transportation management and response pattern during disaster periods on both the technical and policy levels. Finally, the paper discusses social security systems for disaster relief and reduction in three respects, i.e., reach-out for law recognition and enhancement, awareness of disaster relief, and readiness of disaster relief.
