Trouble spots statewide

The map below is based on crash data collected from the Maine Department of Transportation from 2009-2011. To be able to rank intersections and segments of road on a level playing field, MDOT uses a formula known as crash rate factor (CRF) that takes into account the number of crashes and the number of vehicles traveling through each site and then compares what actually happens at the site to what the state predicts will happen based on a site’s history.
