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

The Bend office of Kittelson & Associaties, Inc. (KAI) recently held an interactive workshop on the principles of NCHRP 613 – Guidelines for Selecting Speed Reduction Treatments at High Speed Intersections. Brian Ray, of KAI, was the Principal Investigator (PI) on this project and he led the discussion for a packed audience in Bend. The guidelines include information about effects of speeds and the conditions that may contribute to undesirably high speeds at intersections. He shared background on the guidelines development, described the range of included treatments, reviewed the treatment implementation process framework, guided attendees through Guidelines case studies, and illustrated how these concepts have been applied at project locations in Central Oregon. A PDF of Brian’s presentation is listed below for your reference.
