Action item B6 of Arlington’s Vision Zero Action Plan outlines the County’s approach to designing streets and trails to be safe for all users. Pursuant to this, the County will update existing design standards and guidelines and create new ones to reflect the fact that safety is our top priority. These guidelines will be kept up-to-date to reflect the latest safety research, standards and best practices from across the country, and to include lessons learned from systemic crash analysis.
The County recognizes the importance of responding swiftly to safety issues, so these guidelines are intended to be flexible and allow staff to exercise some discretion in determining the most effective solutions for each individual situation.
- Bus Stop Guidelines (Updated March 2020): This manual lays out the guidelines for bus stops within the County, and emphasizes accessibility for disabled riders, consistency in the design of bus stops, safety for all road users, and convenience and comfort for transit riders.
- Marked Crosswalk Guidelines (Updated August 2021): This manual describes the guidelines for the design and placement of marked crosswalks, with a focus on safety, accessibility, and uniformity.

Guidelines in Development
Currently the County is working to develop guidelines for the implementation of Speed Cameras and speed limit changes within School Zones.
Multimodal Safety Toolbox
County guidelines (which we have developed and are developing) will help us determine how to most effectively use the safety tools at our disposal, which include pavement markings, pedestrian and cyclist infrastructure, and rapid rectangular flashing beacons (RRFBs), to name a few. At present, our Multimodal Safety Toolbox is under development. Sign up for Vision Zero updates and look out for upcoming engagement to help us create our Toolbox.
