Bicyclist Distinguishment at Traffic Signals Using Infrared Camera Technology
Shaun Quayle of Washington County, Oregon and Chase Hildner of DKS Associates

The speakers will summarize the goals and evaluation results of Washington County, Oregon's pilot project efforts to leverage infrared video cameras to distinguish bikes on approach at signalized intersections. They will also touch on the signal phasing and timing applications to be employed.

Key Learning Outcomes

  • Understanding of the problem cyclists often face at signalized intersections with legacy detection systems.
  • Results of Washington County's efforts to determine the accuracy of detection systems on distinguishing bicyclists from other roadway users.
  • Awareness of the signal timing applications to enhance cyclist safety.
