Dynamic Traffic Assignment #3: No Sweat, a More Detailed Look at DTA (Part 1)



Date: Monday, November 30, 2009
Time: 2:30pm - 4:30pm Eastern Time
Location: Online


Two practitioners will discuss one particular modeling aspect of their DTA modeling experience. These topics could include initial model preparation, data collection, modeling validation and calibration, computation time, modeling outputs and post-processing, communication and feedback from project sponsors, etc. These discussions are aimed at documenting lessons learned from these projects for future model use and model improvements.


Jeff Shelton, Texas Transportation Institute

Mr. Shelton is an Assistant Research Scientist with Texas Transportation Institute's Center for International Intelligent Transportation Research. He graduated from the University of Texas at El Paso (UTEP) with both his bachelors and masters degrees in civil engineering. He is currently working on several research projects that incorporate multi-resolution simulation modeling which include DTA models.

Mr. Shelton will discuss: Multi-Resolution Model Integration - Why is it Important and How to Make it Work? This presentation is aimed at providing insights into model integration at different levels of resolution by providing practical solutions to various transportation studies. Tools used to integrate simulation models, calibration methods, and consistency issues will be addressed using case studies from El Paso, TX.

David Roden, AECOM

Mr. Roden is a senior consulting manager with AECOM with 27 years of experience in travel demand forecasting, traffic simulation, transportation planning, and commercial software development and support. He is the project manager for the White House Area Transportation Study and the TRANSIMS projects in Atlanta, Georgia, Columbus, Ohio, and Portland, Oregon. He pioneered advanced analytical methods used in 24 hour simulations of regional highway and transit networks and evaluated and tested EPA's MOVES software for FHWA. Mr. Roden has a B.S. from the University of Arizona and a M.E. from the University of California at Berkeley.

Mr. Roden will discuss implementing DTA for the White House Area Transportation Study. The presentation will focus on developing and calibrating dynamic network assignments as part of the White House Area Transportation Study in downtown Washington D.C. Issues related to converting and refining supply and demand data from traditional travel models, adding temporal sensitivities and traffic controls, and achieving dynamic user equilibrium and network stability within a multi-modal environment will be discussed.
