U.S. map of towns with limited emergency evacuation routes

Our data scientists analyzed ~30,000 U.S. towns with <40,000 residents to identify communities with fewest “exit routes” per resident. Explore the interactive map for 675 towns with 3X the average evacuation risk of all towns analyzed.

Are you with a department of forestry or fire protection? Contact us, and we’ll follow up with more detail.

Map Key:

Pink areas pinpoint the 675 U.S. communities with limited evacuation routes. Refer to the section below the map for underlying methodology.

Hover over each area for the town’s population, the number of exits, and the main exit “load,” indicating the percent of daily traffic using the main exit route.

Methodology:

Using StreetLight’s vast repository of nationwide, hyper-local transportation metrics, 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” available in each town and the average “load” on the most-used exit, weighted by town population. We then selected a subset of 675 U.S. communities that scored at least 3 times the average of all towns analyzed. You can download the full list and accompanying statistics, including the following detail for all 675 communities, broken out by state:
