County-wide: DES is implementing small-scale safety improvements throughout Arlington at locations identified either through (1) data analysis, including reviews of crash or behavior data, or (2) reports from the Arlington County Police Department, Arlington Public Schools, or members of the community.
DES identifies small-scale safety projects through analysis on both on an annual and ongoing basis:
- Annual Crash Analysis: Staff conduct a comprehensive annual analysis each year, which includes a review of the previous year’s crash patterns, as well as longer term crash trends and patterns. This includes a systemic review of common factors in severe/fatal crashes to identify high risk circumstances and roadway characteristics and (2) a “Hot Spot” analysis that identifies individual intersections or locations that experience high numbers of crashes. Following the annual crash analysis, staff identify and implement mitigation efforts to address the patterns and hot spots found through the crash analysis. For more information on annual crash analysis, click here.
- Community-Reported Crash Analysis: Ad-hoc crash analysis is prompted by safety-related reports from County staff, our partners, or community members. These ad-hoc analyses focus on identifying specific needs or conditions related to a site.
Construction or implementation of these small-scale safety improvement projects will occur on a rolling basis throughout the year.
In 2021, we hope to accomplish the Quick-Build Safety projects listed below.
2021 Quick-Build Safety Projects
Williamsburg Blvd & George Mason
- Identified through the annual hot spot analysis in 2018
- Design concept include curb extensions on the north end of the intersection, extension of the median, and improvement of the bus stop on the northeast corner of the intersection. (Plans coming soon)
- Additional Notes: The Williamsburg Boulevard corridor was evaluated, and the intersection of Williamsburg & N George Mason Dr showed an increase in total crashes in 2018. Most of these crashes were angled crashes, so we assessed various options. We evaluated the intersection for a new traffic signal and an all way stop, and this location did not meet the warrants for either. Our next step was to improve the geometry of the intersection. The road width of Williamsburg Boulevard changes from one side of N George Mason Dr to the other, so we determined this would be a good opportunity to build curb extensions on the NE and NW corners to better align the geometry. The curb extensions as well as the proposed improvements to the existing medians will better align the curbs, curb ramps, crosswalks and stop bars. These improvements will increase intersection sight distance so that vehicles at the stop sign can see oncoming vehicles with more clarity, as well as provide a better ADA compliant path for pedestrians. Additionally, this project will improve the existing bus stop on the NE corner of the intersection to meet ADA compliance.
26th St N & Harrison St
- Identified through the annual hot spot analysis in 2017
- Improvements in 2018 included (1) new pavement markings and bollards to reduce turning speeds and provide additional pedestrian refuge and (2) an in-street pedestrian sign to bring extra visibility for pedestrians crossing.
- Because these improvements are helped to reduce crashes, the County will be permanently building out the curb extensions in concrete. This will enhance safety and reduce the need for ongoing maintenance. (Plans coming soon)
Meade St & Arlington Blvd
- Identified through the annual hot spot analysis in 2018. (More information coming soon)
About the Project
Arlington County’s Vision Zero transportation safety program provides a comprehensive and holistic approach to eliminate traffic fatalities and serious injuries. These small-scale safety improvement projects are a part of the greater Vision Zero program effort. They include any safety projects identified through programmatic analysis or community reports and are funded under either general funds or the Vision Zero safety program.
Some projects are small enough in scale to be funded through the general operating fund. Others are funded through the Vision Zero program under the Arlington County Capital Improvement Plan and are funded by a mix of state and local sources.
