OVERVIEW

Join us for a two-part seminar looking at video-image processing technology for bicyclists and pedestrians.

FIRST PRESENTATION
Bicyclist Distinguishment at Traffic Signals Using Infrared Camera Techology

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.

SECOND PRESENTATION
Ped Counts - A Case Study of Clark County
Subhadipto Poddar of Clark County, Washington

With emerging video detection technologies, traffic detection has seen a major improvement over the past few years. Be it the vehicular detection for operational and safety studies or the pedestrian safety evaluation, deep learning algorithms like YOLO, RNN, CNN, and others have seemed to provide aid to different agencies across the globe. However, like all systems, the evaluation of these detection systems is a key to the system's behavior. The present work involves a case study of different video detection systems for Clark County, WA. The study involves verification of the systems in use, their evolution over the last few years, and key takeaways from them. Finally, a conclusion is drawn based upon the evaluation so conducted.

Key Learning Outcomes

  • Detection of pedestrians using video is not as easy as it seems.
  • How can agencies conduct simple evaluation of their existing systems.
  • Need to rely on video analytics for future transportation analytics.
