Application of ArcMap extension tools on Disaster Management Planning of Port Alberni
Disaster preparedness is one of the effective ways to mitigate the economic, environmental and human losses of disasters. This paper explores the applicability of the Pedestrian Evacuation Analyst tool and network analysis on disaster management planning of Port Alberni, British Columbia. Pedestrian Evacuation Analyst tool, developed by United States Geological Survey (USGS) was used in this study for examining the pedestrian, self-initiated evacuation from the tsunami inundation zone of Port Alberni. Researchers for this study considered two scenarios: one where the travel speed was considered as fast running (3.85 m/sec) and other where the travel speed was considered as average walk (1.22 m/sec). The results show that people with fast running speed living away from the safe zone can comparatively be in less danger than the people with average walking speed living in the same location, because they can travel faster. However, the study did not consider the population data to create the maps, which is one of the weaknesses of this study. The researchers suggested to integrate data of the size and location of different population demographics with travel-time maps for better disaster management planning. For future development of the application, researchers suggested to develop the options of comparing multiple scenarios and aggregating the multiple scenario results into a larger time map.
