Jones, J.L., Peters, J., and Wood, N.J., 2018, Pedestrian tsunami evacuation results for two tsunami-evacuation zones (standard and extreme) and three travel speeds (impaired, slow, and fast walk) for O'ahu, HI: U.S. Geological Survey data release, https://doi.org/10.5066/F7862FNT.

Summary

The travel time map was generated using the Pedestrian Evacuation Analyst model from the USGS (https://geography.wr.usgs.gov/science/vulnerability/tools.html). The travel time analysis uses ESRI's Path Distance tool to find the shortest distance across a cost surface from any point in the hazard zone to a safe zone. This cost analysis considers the direction of movement and assigns a higher cost to steeper slopes, based on a table contained within the model. The analysis also adds in the energy costs of crossing different types of land cover, assuming that less energy is expended walking along a road than walking across a sandy beach. To produce the time map, the evacuation surface output from the model is grouped into 1-minute increments [...]

Purpose

The communities of O'ahu, HI are threatened by distant tsunamis from earthquake sources from around the Pacific Ocean basin. Maps of evacuation travel times within tsunami-evacuation zones can be used by emergency managers and community planners to identify where to focus evacuation training and hazard education.
