Risk Score
This corridor is in an area with high demand, is a regional crash hotspot, and is high risk. The non‐motorized risk score indicates areas where the odds of a bicycle or pedestrian crash occurring are disproportionately high based on crash risk factors related to the built environment, trip origin and destination, and travel behavior.
Areas with higher risk are indicated in red. While only a few areas along the segment have a significant crash history, as shown in the hotspot map, the entire segment is high risk. Compared to the rest of the region, this segment is among the highest risk locations across the region and has a similar risk score to areas along Nolensville Pike and Harding Pike.
