The Development of a Cooperative Safety Performance Assessment Framework for Connected and Automated Driving System-Equipped Vehicles

Posted by nbl42 on November 12, 2019

Sponsor: Institute of Automated Mobility (IAM) through the Arizona Commerce Authority (ACA)

PI: Brendan J Russo

Start Date: August 2019

The rapid development and testing of connected and automated driving system (ADS)-equipped vehicles (CAVs) in our urban communities raises serious concerns for public safety. To address these concerns, the Institute of Automated Mobility (IAM) established by Governor Ducey in Arizona has embarked on an innovative approach to driving safety performance assessment that cooperatively utilizes both infrastructure and vehicle data. Data from… Read more

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
