Session No. 4A

Session Title: Lessons Learned from Quantitative Approaches to Transportation Safety

This session will focus on various quantitative and data-driven approaches to quantify and improve transportation safety outcomes. The focus is on situations where quantitative methods are used to learn more about relationships between safety performance and other factors, as well as quantitative methods can be used to improve estimates of safety performance in the future.

Moderator: Vikash V. Gayah, Associate Professor, Department of Civil and Environmental Engineering, Penn State

Speaker Bios

Pete Jenior is an associate wngineer with Kittelson & Associates, Inc. in Baltimore and leads projects throughout the Mid-Atlantic. His work in Pennsylvania includes traffic analysis and design for districts and safety and roundabout support for Central Office. Jenior was the lead author of the FHWA Part-time Shoulder Use Guide, and is the principal investigator of NCHRP Project 17-89 Safety Performance of Part-Time Shoulder Use on Freeways.

Eric Donnell is the Director of the Thomas D. Larson Pennsylvania Transportation Institute, and a professor of Civil Engineering, at Penn State. He is chair of the TRB Design Section, and a member of the PennDOT-FHWA Statewide Transportation Innovation Council. Donnell has 20 years of research and teaching experience related to traffic safety, speed management, and highway design. He serves as an associate editor and advisory board member on two international journals and is a past leadership fellow of the Eno Foundation.     

R.J. Porter (Penn State ’99, ’00, ’07) joined VHB’s Raleigh office as a highway safety engineer in January 2017. He was previously the director of the transportation engineering group in the Department of Civil and Environmental Engineering at the University of Utah. He has more than 19 years of experience leading and supporting NCHRP, FHWA, USDOT RITA, SHRP2, and state DOT contracts. Porter has served as principal investigator and/or project manager for more than $13 million in contract work spanning performance-based planning, programming, and design; road safety; traffic operations; and user performance and behavior. His work has resulted in more than 80 published papers, research reports, and practitioner guidelines documents, as well as over 80 technical and outreach presentations in the United States and abroad. Porter served as the first chair of the TRB Subcommittee on Performance-Based Analysis from 2007 through 2016, leading efforts to advance performance-based analysis in project development, identifying successful case studies, and developing future research needs. His most recent work advances emerging areas in road safety, including safe system approaches, automated vehicles, transportation systems management and operations, short-term crash prediction, and surrogate measures of safety.
