Safer city streets for everyone

"Sandbox" Pilot Project
in Partnership with DDOT

Passage, based in Washington, DC, helps cities examine, enforce, and evolve traffic behavior for safer, better, and more equitable streets. We are conducting this pilot project as part of DDOT's "sandbox" technology evaluation program. Consult the FAQ for more information.

Passage DDOT Pilot FAQ

What is the Passage-DDOT Pilot Project?
Passage is a DC-based company developing technologies that will help cities improve the safety of their streets. The DC Department of Transportation (DDOT) is running a program to partner with companies to trial new technologies in "real world" conditions. As part of this program, Passage has deployed its Street Sensors on several street poles around the District.
What is the Passage Street Sensor?
The Street Sensor is a compact, inexpensive device that can measure vehicular speeds. The Sensor can record videos and license plate numbers of vehicles exceeding the speed limit.
Will the system issue speeding tickets?
No, the purpose of the pilot project is to evaluate the capabilities of the system. No citations or other enforcement actions will be taken.
What kind of data is being collected?
The sensors are collecting anonymous speed statistics based on radar readings. For vehicles that exceed the speed limit, a short (4 second) video may be taken and a license plate recorded. The data is stored in a secure system accessible only by Passage and its partners evaluating the pilot.
Will this affect my privacy?
Most of the data collected is anonymous speed statistics. Videos of speeding vehicles may not be anonymous. Videos only focus on the street and for very brief time intervals. They are only activated upon detecting speeding behavior. This privacy expectation is no different than the Automated Traffic Enforcement Systems already widely deployed across DC.
How is Passage different than typical speed cameras
For one thing, our sensor is much smaller and less expensive. This means that it could potentially be deployed in a range of scenarios where conventional systems are too big or expensive. Our system might be used to inform placement of the more expensive systems. Or to measure driver behavior in sensitive areas, such as around schools. Our vision is to replace "speed traps" with "safety zones".
