What is it?

The Pedestrian Evacuation Analyst is an ArcGIS extension that estimates how long it would take for someone to travel on foot out of a hazardous area that was threatened by a sudden event such as a tsunami, flash flood, or volcanic lahar.  It takes into account the elevation changes and the different types of landcover that a person would encounter along the way. 

What is new with the tool?

Oct. 24, 2014

The latest version of the tool, EvacAnalystInstaller_20141023, is available by clicking on the DOWNLOAD TOOL button.  The tool is now compatible with ArcGIS 10.3.1 and has improved error reporting. Please uninstall the old version before installing the new version.

What does it do?

The Pedestrian Evacuation Analyst produces maps of pedestrian travel times to high ground for every location in the threatened area (hazard zone). If provided information about where people are located in the hazard zone, the tool will also calculate counts of people at different travel time intervals and generate graphs and tables of the results. The tool can also be used to examine the potential benefits of vertical evacuation structures, which are buildings or berms designed to provide a local high ground in low-lying areas of the hazard zone.
