Traffic Engineering Mission & Vision
Mission: The Traffic Engineering Division’s mission is working together to foster a thriving Alexandria by providing improved mobility in Alexandria and the region, through sound engineering, design, technology implementation, and regional cooperation.
Vision: The Traffic Engineering Division is a proactive and effective organization with a drive towards technological innovation.
- Pavement Sensors have been installed in three locations. These sensors alert the City when temperature drop below certain temperatures so we can proactively treat the roadway to prevent ice and freezing.
- Traffic Camera Live Feed is now available via broadcasting on the Traffic View website.
- The City has become a WAZE Connected Citizens Program Partner. By sharing publicly available information, the partnership enables WAZE to direct traffic around incidents and road closures and enables the City to respond more immediately to accidents and congestion on their roads. Waze aggregates the partners' data on their App platform, resulting in succinct and thorough overviews of current road conditions that can be used for more informed planning.
- The City has become a partner in Metropolitan Area Transportation Operations Coordination (MATOC) program. This program is a coordinated partnership between transportation agencies in D.C., Maryland, and Virginia that aims to improve safety and mobility in the region through information sharing, planning, and coordination. The MATOC program makes travel
smoother and safer for the City of Alexandria by providing essential information on transportation operations in the National Capital Region.
Alexandria is committed to investment in transportation technologies that improve road safety and traffic management while also preparing the City to take advantage of future transportation infrastructure advancements, such as self-driving cars and real-time traffic management. The City's Smart Mobility initiatives are keeping City streets safe and running smoothly now, while also laying the groundwork for emerging technologies that will shape transportation over the next five, 10, 20 years and beyond.
- Intelligent Transportation Systems (ITS) Master Plan
- ITS Integration Projects
- Transit Signal Priority & Emergency Vehicle Preemption
- Adaptive Traffic Signal Control
- Travel Time & Speed Sensors
The Traffic Engineering Division operates the City’s Transportation Management Center (TMC). The Center uses technology to manage traffic and critical events such as snow removal, weather related operations and other special events.
Being Forward Thinking and innovative are guiding principles of the Smart Mobility Program. With emerging technology that changes constantly, the City aims to proactively assess new technology solutions to better manager traffic and advance City goals. The Traffic Engineering Division researches and evaluates cutting edge technology for implementation.
Speed cushions are traffic calming devices that use vertical deflection to slow motor-vehicle traffic in order to improve safety conditions. The use of vertical deflection devices is most commonly found where vehicle speeds are mandated to be low, usually 25 miles per hour.
Traffic Controls and Signals
Traffic signals can improve safety for pedestrians, bicycles and motorists as well as provide orderly movement of traffic when designed and installed properly. Signals that are installed when no legitimate need exists can increase vehicle stops, traffic delays, fuel consumption, crashes and breed disrespect for other traffic signals. Installation of traffic signals is preceded by a thorough engineering study.
To report an issue with a traffic signal, please type in "traffic signal" through the City's Alex311 Customer Service Portal.
All-Way Stop Control
The stop sign is a traffic control device that is installed when it is determined a full stop is always required on an approach to an intersection. The City of Alexandria is required to follow the requirements in the Federal Highway Administration’s Manual on Uniform Traffic Control Devices (MUTCD) for stop sign installation. The MUTCD contains warrants which must be met before a stop sign can be installed. To request a stop sign installation, please review, complete, and submit the City of Alexandria Stop Sign Request Form.
The purpose of installing No Thru Trucks signs is to
restrict any combination of truck, tractor truck, trailer, or semitrailer on
the requested roadway (pickup trucks or panel trucks are exempt). The City maintains a Truck Route Map with routes and restrictions. Restricting large trucks maintains the character of the community, decreases frequency for asphalt and pavement maintenance, and ensures large trucks are traveling along
designated truck routes. For more information on the process for requesting a No Thru Trucks sign installation, please review, complete, and submit the
following form: City of Alexandria No Thru
Truck Sign Request Form.
Projects, Programs & Studies
The Traffic Engineering Division staffs the City's Traffic and Parking Board. All matters concerning traffic, parking and taxicabs are presented to the Traffic and Parking Board for consideration prior to action by the Director of the Transportation and Environmental Services Department or presentation to City Council. The Board investigates, studies and analyzes traffic and parking problems within the city, provides feedback to staff on plans, methods and means to control and relieve parking and traffic congestion, has jurisdiction over taxicabs, and renders advice and recommendations to the City Manager, the Planning Commission and City Council.
