Impacts of Intersection Treatments and Traffic Characteristics on Bicyclist Safety

Posted by nbl42 on November 1, 2019

Sponsor: Oregon Department of Transportation (ODOT)

PI: Brendan J. Russo, Co-PI: Edward J. Smaglik

Project Report: https://www.oregon.gov/odot/Programs/ResearchDocuments/SPR833FinalReport.pdf

In urban and suburban locations, intersections are where a variety of transportation modes converge, thus leading to an increased potential for conflicts, including those between bicyclists and motor vehicles. A common crash type involving bicycles at intersections is the “right/left-hook” where a right/left-turning vehicle collides with a through bicyclist. While various geometric treatments and signal control strategies (e.g. bike boxes, mixing… Read more

Evaluation of Inlaid Pavement Markings in Northern Arizona

Posted by nbl42 on

PI: Brendan J Russo

Sponsor: Arizona Department of Transportation (Prime: CivTech)

Project Start Date: 2016

This project involves an evaluation of the potential safety impacts of inlaid pavement markings on I-40 and I-17 in northern Arizona using the Empirical Bayes (EB) methodology.  Inlaid pavement markings are designed to better withstand snow plow activities and maintain their retroreflectivity better than standard pavement markings. The project entails collecting and analyzing crash, geometric, and environmental data for both treatment sites and control sites. Statistical software… Read more
