5 11 Block Bladensburg Road NE SW/B 13.5 # Crashes by Year Speed Camera Installed on 8/1/ /1/211-8/1/212 8/1/212-8/1/213 The Bladensburg Road Corridor is listed as one of the top ten high frequency crash corridors from 29 to 211, according to the report TRAFFIC SAFETY STATISTICS REPORT FOR THE DISTRICT OF COLUMBIA (29-211) 1. Safety Nexus This site presents the following safety considerations which may support the nexus between the speed camera and traffic safety: 1. Speed Data The 85 th percentile speed is the same as the posted speed limit at this location in the southwest-bound direction. 2. Crash Data This location experienced a high frequency (14 crashes) of injury-related crashes. The Bladensburg Road Corridor is listed as one of the top ten high frequency crash corridors from 29 to 211. There was an increase in the number of crashes after the installation of the camera, although only by 3 crashes. 3. Field Assessment The following site characteristics suggest a need for a safer travel environment: a. There is on-street parking in this area. b. There are multiple bus stops which generate pedestrian activity. Although the speed data analysis showed the 85 th percentile speed to be the same as the posted speed limit in the southwest-bound direction, due to the elevated number of injury-related crashes, the specific site 1 DDOT, TRAFFIC SAFETY STATISTICS REPORT FOR THE DISTRICT OF COLUMBIA (29-211), pg.8.
