Map Key:
Light pink areas indicate current fire boundaries; Dark pink areas indicate U.S. Census boundaries of towns with limited evacuation routes located within 10 miles or less of a fire
Yellow areas indicate U.S. Census boundaries of towns with limited evacuation routes further than 10 miles from a fire boundary
About the map:
Our data science team analyzed the approx. 30,000 towns in the U.S. with populations under 40,000 based on U.S. Census, scoring them using a ratio of the number of roadway “exits” from each town and the average “load” on the most-used exits, weighted by town population. We then selected a subset of approx. 800 communities that scored at least 3 times the average of all towns analyzed. You can download the list, which includes the following detail for the first 100 communities on this list:
— POPULATION, based on U.S. Census
— EXITS, i.e. the number of usable vehicle exits incl. paved and dirt roads
— MAIN EXIT LOAD, i.e. the % of daily traffic using the main exit route
