Emergency Transportation Planning – Earthquakes and Bridge-Collapses in Arkansas

I worked as a geospatial consultant on a project for the Mack-Blackwell Rural Transportation Center, Models for Disaster Relief Shelter Location and Supply Routing (MBTC DOT 3028), looking at earthquake emergency response planning in Arkansas.

This map shows one of the many scenarios with red dots marking collapsed bridges impeding network travel, and purple lines marking the resulting routes between emergency supply depots or other facilities and population demand points.

The project was run by researchers in industrial engineering with no GIS skills. I was asked to act as a consultant, and wound up being a research assistant on the project for several weeks. My work on the project involved mainly network GIS analysis. I helped prepare and update the network data, performed digitizing to help complete a bridge dataset, and developed custom Python scripts to perform Origin-Destination Cost Matrix calculations with variable barriers (representing different emergency scenarios where a certain number of road segments were inaccessible due to bridge collapses) and location/allocation analyses. The full report is available online here.
