Our department has two missions. The first is to advance public and transportation safety. The second is to manage the Boston’s street network to best and fairly serve all users.

We strive to guarantee safe and efficient travel into and around Boston. We always consider pedestrians, bicyclists, motorists, passengers, and everyone who takes public transportation. Our work attempts to improve safety and traffic flow while balancing residential and commercial needs for street parking. We use coordinated planning, engineering, enforcement, and community engagement to guide our work.

We always try to take advantage of current technology to improve what we do, from customer service to new programs.
