The Traffic Operations Section maintains over 50,000 street and traffic signs on the city street system. Street and traffic signs include signs such as stop, yield, speed limit, no parking, warning, school and pedestrian and street name signs.

Street and traffic signs are installed based on a traffic engineering review and in accordance with National Standards for such traffic control devices. The shape, color and meanings of some standard street and traffic signs are reviewed by the state drivers licensing procedures.

Street and traffic signs play a key role in providing for driver and pedestrian safety and directions.
