The AASHTO Highway Safety Manual lists assuming the lead driver will go through a green or yellow light, but the lead driver stops and changing lanes to avoid a slowing or stopped vehicle 1 as two errors leading to rear-end and sideswipe crashes. Both of these errors can be decreased with a decrease in travel speed. The speed camera was installed on 12/17/212. The graph on the next page shows the number of crashes in the 3 years prior to the speed camera s installation (74, 78 and 87) and the year after the speed camera s installation (7). There was a decrease in the number of crashes after the installation of the camera. 1 AASHTO Highway Safety Manual, 1 st Edition, 21; Volume 1, page 2-13 W5-4 District Department of Transportation 55 M Street, SE, Suite 4 Washington, DC 23

This site is located within.5 mile of a top 5% high accident locations for : New York Avenue NE at Bladensburg Road NE. 3 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 was much higher than the posted speed limit at this location. 2. Crash Data There was an elevated number of speed related crashes at this location, including rear end and side swipe. This location experienced a high frequency (65 crashes) of injury related crashes. The New York Avenue Corridor is listed as one of the top ten high frequency crash corridors from 29 to Field Assessment The following site characteristics suggest a need for a safer travel environment: a. There is one school in the area: Washington Mathematics Science Technology Public Charter High School (WMST PCS). 2 DDOT, TRAFFIC SAFETY STATISTICS REPORT FOR THE DISTRICT OF COLUMBIA (29-211), pg.8. 3 DDOT, Top 5% High Accident Locations Map for W5-41 District Department of Transportation 55 M Street, SE, Suite 4 Washington, DC 23

6 27 Block New York Avenue NE W/B b. There are several bus stops in the area which generate pedestrian activity. Due to the speed data analysis, the elevated number of speed-related crashes and injury-related crashes, the specific site characteristics and pedestrian generators, there is a nexus between traffic safety and the speed camera at this location.
