Connecting ramp terminal traffic signals to regional traffic control system in Washington State DOT's northwest region

June 2009
SR 104,Edmonds,Washington,United States

Summary Information

The goal of this project was to connect arterial traffic signal systems near freeway ramps to a central signal system. This would provide the communications infrastructure for future coordinated operations. Three jurisdictions within the region were upgraded as part of this project.

The second of three projects interconnected arterial traffic signals on State Road 104 in Edmonds near freeway ramps into the regional traffic signal system by installing the following:
  • Six traffic signals on SR 104 along with new 2070 traffic signal controllers
  • Five CCTV cameras
  • Fiber connection to the Washington State DOT's maintenance facility on SR 104
  • Connection to the traffic signal at the intersection of SR 104 and SR 99
The maintenance required to keep the fiber optic interconnection in operation is much less than what was required to keep the previous twisted-pair, copper wire in operation.
