The Future of Dynamic Traffic Assignment


About the Workshop


Transportation planners and engineers today are faced with complex analyses of innovative applications such as system performance, reliability, managed lanes, congestion pricing, one-way two-way conversion, construction detour, and more. Traditional analysis tools, including travel-demand modeling and microsimulation, often do not meet the analyst’s needs nor the available budget. As a result, simulation-based Dynamic Traffic Assignment (DTA) has been rapidly gaining popularity and becoming the tool of choice for such applications. Join us for an informative workshop on DTA. The workshop will provide a background on DTA development, its state of the practice, applications, and future direction. This session also brings together experts on this topic who will walk through examples of how DTA has been applied in Tucson, as well as Portland.

There is no cost to attend this brown bag lunch session and lunch will be provided. The workshop is equal to 2.0 professional development hours (PDH).

Based on feedback from recent workshop participants, we've added an extra 30 minutes at the beginning of the session to allow time for attendees to sign in and network with other public agency colleagues from around the area. The presentation will begin promptly at 11:00am.

We hope you can join us for this informative workshop on this important and "dynamic" topic.

Peter Bosa
Associate Transportation Modeler, Portland Metro

Peter is a transportation modeler with Portland Metro's Transportation Research and Modeling Services program. He has over 4 years of experience in applying transportation models for regional- and corridor-level forecasting of travel behavior, air quality and vehicle emissions, and applications for the Federal Transit Administration's New Starts program. He is one of the primary developers of Metro's regional DTA network.

Khang Nguyen, PE
Associate Engineer, Kittelson & Associates, Inc., Tucson, AZ

Khang has 15 years of experience in traffic engineering, with particular expertise in capacity and operations analysis, traffic design, and freeway modeling. He is highly skilled in the use of traffic analysis tools, including Synchro/SimTraffic, CORSIM, VISSIM, DynusT, and the HCM methodologies. He's applied DynusT to model an I-10 section in Tucson and is currently leading a CORSIM team to model the Golden Glades Interchange, aka Spaghetti Bowl, in Miami, Florida. Khang holds a B.S. (Cal-Poly) degree in civil engineering and M.S. (Cal-Berkeley) degree in transportation engineering.

Wayne Kittelson, PE
