A framework: Implementation of smart city concept towards evacuation route mapping in disaster management system

Abstract

Due to the complex nature of disaster, elaborating smart city environment has being important matter in term of enhancing the resilience, awareness and preparedness. Therefore, this research propose a collaborative framework of disaster awareness system that can integrate multiple data resources in smart city ecosystem. The system architecture consist of four tiers; (1) sensor tier, which is responsible for retrieving and updating information about reality from sensors; (2) database tier, which is responsible for collecting information from related domain resources (3) decision support tier, with respect to examine the continuously updated situations for making emergency decision; and (4) alert tier, which is responsible for informing and warning citizens who living within risk area. By using earthquake impact assessment of Taiwan earthquake, the framework is built in knowledge to evaluate service area of hospital and provide evacuation route using network analyst. From infrastructure perspective, standards are introduced to resolve the various heterogeneity issues between different stakeholders. The result of hospital service area analysis is 1207 km2 and decreases about 474.5 km2 after the earthquake. Moreover, the comparison of route analysis between before and after earthquake indicates that the implementation of smart city concept and network analyst sussessfully minimize travel time until 10 minutes.
