Applying the Principles of NCHRP 613: Guidelines for Selecting Speed Reduction Treatments at High Speed Intersections


Let’s slow things down: Applying the principles of NCHRP 613 Guidelines for Selecting Speed Reduction Treatments at High Speed Intersections


Brian Ray, of Kittelson & Associates, Inc. (principal investigator on this research project) will lead this session and provide an overview of the published Guidelines. The guidelines include information about effects of speeds and the conditions that may contribute to undesirably high speeds at intersections. He will share background on the guidelines development, describe the range of included treatments, review the treatment implementation process framework, guide attendees through Guidelines case studies, and illustrate how these concepts have been applied at project locations in Central Oregon.

There is no cost to attend this session and beverages will be provided. The workshop is equal to 1.5 professional development hours (PDH).

Please note: Based on feedback from recent workshop participants, we've added an extra 30 minutes at the beginning of the session to allow time for attendees to sign in and network with other public agency and private company colleagues from around the area. The presentation will begin promptly at 3:00pm.

We hope you can join us for this informative workshop!
