Number of vehicular collisions.
Annual Vehicle Collisions, 2006-2014
|Year||Number of Individual Collisions||Collisions per 100,000 VMT (Arlington)||Collisions per 100,000 VMT (Nationally)|
Vehicle collisions are tracked by the Transportation Engineering and Operations (TE&O) Bureau. Vehicular collisions involving one or more vehicles are recorded on an annual basis. Annual VMT (Vehicle-miles Traveled) estimates were obtained from the Virginia Department of Transportation. By using a simple calculation of collisions per year and annual vehicles miles traveled, an average collision rating can be obtained. This rate can be an effective tool in determining the relative safety of a roadway segment.
Nationally, motor vehicle collisions are the leading cause of death for all people ages 5–34, according to the Centers for Disease Control. The increase and decrease of collisions, proportional to the fluctuation of annual VMT, demonstrate Arlington's success in sustaining roadway safety. Reducing the total number of crashes, the number of persons injured in crashes and the number of fatalities is the goal of safety improvements to the transportation network. This measure supports the MTP Goal 3: Promote Safety.
The total number of vehicular collisions has dropped by 16 percent between 2013 and 2014. Similar to some of the other collision tracking data, there appeared to be a spike in 2013's count of vehicular collisions. Although there was a significant drop from 2013 to 2014, collisions in 2014 remained higher than the 2008 to 2014 period. This reflects national trends, as during the recession, lower vehicle miles traveled resulted in a reduction in vehicular collisions.
Compared to the national rate of collisions per 100,000 VMT, Arlington's rate has been one to three collisions per 100,000 VMT higher than the national average.
