The Transportation Engineering and Operations (TE&O) Bureau collects and tracks collision data based on the severity of crash as in whether an injury occurred and whether the injury was fatal or non-fatal. The Virginia Department of Transportation estimates the number of annual Vehicle Miles Traveled (VMT) on all roads, for each county. Vehicle miles traveled is determined by dividing the total number of miles traveled (in the County) by the current population. Ideally, increases and decreases in overall VMT impacts collision data; however, fatality rates provide a more accurate depiction of the overall safety trends.
This measure encompasses all vehicular-related crashes for which an officer responded. Considering collision trends, severity of collisions, and fatality rates will help Arlington County assess the success of overall transportation safety initiatives and aid in assessing whether it meets the Master Transportation Plan's goal of promoting safety for all modes of transportation. Comparing collisions to the annual VMT provides perspective; overall collision rates should rise and fall with annual VMT. This measure ties into the MTP Goal 3: Promote Safety.
During the last year, the total number of collisions fell by 490, from 2,970 in 2013 to 2,480 in 2014. For the period reported, 2006 to 2013, annual VMT in Arlington County has been relatively stagnant, holding between 4 million and 4.5 million miles per year. However, total number of collisions has varied from 1,900 per year to almost 3,000 annually. There is a significant downward trend in non-fatal injury collision incidents during the study period, dropping from 944 incidents in 2006 to 479 incidents in 2014. Between 2006 and 2012 the County's population increased by 9,000, or 8 percent.
Even with a reasonable increase in population, fatalities have remained low, generally under 4 per year, with the exception of 2009. The record snowfall of 2009 was a contributing factor in some of the fatalities that year.
