This two-part webinar will focus on key areas of roundabout design and construction related to these recent publications:

NCHRP 672 – Roundabouts: An Informational Report, Second Edition
NCHRP 674 - Crossing Solutions at Roundabouts and Channelized Turn Lanes for Pedestrians with Vision Disabilities

And review case studies to review applications involving:

Roundabout Corridors
Roundabouts and Access Control
Roundabouts and Complete Streets
High capacity urban roundabouts
Signing and Marking modifications for improved safety

At the conclusion of the course, participants should be able to:

1) Identify key horizontal and vertical geometric and operational issues
2) Understand the relationship of geometry to safety and geometry to capacity from a
design and construction perspective.
3) Identify issues associated with construction staging and work zone traffic control strategies.
4) Describe non-motorized design treatments for safety.
5) Discuss maintenance management issues including landscaping, snow removal.
6) Recognize design issues pertaining to utilities.

Mark T. Johnson, P.E., CEO, MTJ  Engineering, LLC., Madison, WI, USA

Mark Johnson, P.E., has 16 years of traffic and transportation engineering and planning experience. Mark launched MTJ Engineering, LLC in 2004, following 12 years in public- and private-sector transportation engineering positions, including four years in a municipal transportation department in Colorado and four years at the Wisconsin DOT. He has led the design or design review for private and public sector clients in 24 states and two Canadian provinces.

Mentored extensively by U.K. roundabout design expert Barry Crown, Mark’s experience encompasses the full range of traffic flows and contexts, including low-speed urban, to high-speed rural, to complex three and four lane multi-lane interchanges and roundabouts in series.
He earned a B.S. in Civil & Environmental Engineering (Transportation Engineering emphasis) at the University of Wisconsin-Madison in 1993. He is a registered PE in Colorado, Wisconsin and Oregon. His professional affiliations include ITE and ASCE. 

The planning, design, construction and maintenance components of roundabout development and implementation are all very important with respect to the safety and operational outcomes that can be expected. The web seminar will address design strategies for single lane and multi-lane roundabouts; solutions to key geometric, operational and driver behavior issues that are often prevalent during a post construction condition and which can usually be identified and corrected with application of roundabout design knowledge.

At the conclusion of the course, participants should be able to:

1) Identify key horizontal and vertical geometric and operational issues
2) Understand the relationship of geometry to safety and geometry to capacity from a
design and construction perspective.

The web seminar will address pedestrian safety, pavement marking and signing design, and key maintenance management issues including landscaping, lighting, vertical control and construction staging. Also discussed are a number of issues that are prevalent in a post a construction/operational condition.

At the conclusion of the course, participants should be able to:

1) Describe non-motorized design treatments for safety.
2) Discuss maintenance management issues including landscaping, snow removal.
3) Recognize design issues pertaining to utilities.
