Traffic Signals

Bellevue currently operates and maintains 177 traffic signals. Many of these signals are linked to City Hall, where engineers continually adjust their timing to keep traffic moving. On a typical day, approximately 26 corridors in Bellevue have some traffic signal coordination.

The Traffic Management Center at City Hall is where traffic engineers work to keep traffic flowing every day. During special events and the holiday shopping season, the Center is key to limiting congestion, offering powerful tools for monitoring and controlling traffic, including:

  • Traffic Computer:

    Allows engineers to coordinate traffic signals for better traffic flow and make real-time signal timing adjustments to address current events/congestion.
  • Real-time traffic map:

    Displays current traffic levels on city arterial streets, helping engineers pinpoint congestion locations. The map is also available to the public at help travelers make better trip route and time decisions.
  • Video:
