Real – Time Data Improves Traffic Flow on City Streets

SDOT has begun changing the timing of lights on selected major corridors so that you won’t experience the delay from the side street as described above. How? Well, SDOT is taking away the guess work of signal timing by adding technology using wireless magnetometers which are embedded in the pavement. The magnetometers collect data and feed the information to SDOT’s traffic signal system as well as the department’s Traveler’s Information Map.
