Application of Pedestrian Evacuation Analyst and network analyst tools on Disaster Management Planning of Port Alberni

Project Summary: 

Disaster preparedness is one of the effective ways to mitigate the economic, environmental and human losses of disasters. This project 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. The author for this project considered two scenarios: one where the travel speed was considered as a fast running (3.85 m/sec) speed and other where the travel speed was considered as an average walk (1.22 m/sec) speed. 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 as 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 author 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, the author suggested to develop the options for comparing multiple scenarios and aggregating the multiple scenario results into a larger time map.
