Session 4D: Roundabouts - Current State of the Practice
Session Description: This session will focus on how technology is contributing to the planning, design, and implementation of the modern day roundabout intersection. Specifically, this session will focus on how technology has helped regionally advance the screening, identification, and justification of roundabout intersections; current national best-design practices; and lessons learned.

Speaker Bios:
Dave Vodila has worked as a transportation planner at Urban Engineers for the past 12 years. His previous projects have focused on bicycle and pedestrian planning, traffic calming, and roadway layout and design. His work involves data collection & analysis, concept development, alternatives analysis, web development, and preparation of graphics and reports. His recent projects have focused on crash analysis for safety projects in New Jersey and Pennsylvania.
Dan Farley is the chief of the Traffic Operations Deployment and Maintenance Section which encompasses traffic signals, work zones, and ITS design programs. He also administers the Green Light-Go and Automated Red Light Enforcement (ARLE) Funding Programs. Dan has been with PennDOT for 13 years, spending the first four years in PennDOT District 4 (Dunmore) before moving to Central Office.
Mike Mastaglio leads Urban’s multimodal projects, integrating various transportation modes into safe, efficient, and sustainable solutions for all users. He has 20 years’ experience in project and staff management of complex, innovative, and multidisciplinary transportation projects and is a leader in national roundabout policy, planning, design, and construction, serving on the TRB and ITE National Roundabout Committees and giving roundabout training. Mike manages PennDOT’s Innovative Intersection and Interchange Support Services Agreement and PennDOT District 6-0’s Districtwide Roundabout Program.
Pete Jenior is a traffic engineer with ten years of experience. He performs road safety studies, retimes traffic signals, designs roundabouts and alternative intersections, and leads research projects. Pete has also served as a lead researcher for NCHRP projects related to ramp and interchange spacing (Report 687) and the evaluation of roundabout corridors (Report 772), and has developed four alternative intersection guidebooks for FHWA. Recently, he was the lead author of FHWA’s Part-time Shoulder Use Guidebook. He is a member of TRB’s geometric design committee and routinely teaches short courses on traffic engineering topics.
Andrew T. Duerr has 23 years of experience in transportation planning and design for clients throughout the eastern United States. This experience includes roundabout planning and design, interchange and corridor planning, road and intersection safety audits and design, pedestrian accessibility, bicycle accommodation, and public involvement/outreach in Pennsylvania, Delaware, Maryland, Ohio, Virginia, North Carolina, Georgia, Maine, Michigan, Wisconsin, and Texas.
