Time: 2:30pm - 4:30pm Eastern Time
Transportation planners, modelers and engineers.
Integrated modeling tools can be used to evaluate many meaningful measures related to system-wide network measures for regional planning as well as corridor level analyses related to operational planning projects. Two practitioners will discuss the use of dynamic traffic assignment (DTA) and the functionalities needed for long-range forecasting and operational planning projects including traffic control, vehicle loading and network consistency. These discussions are aimed at addressing challenges that arise from the use of DTA in large simulation networks through case studies.
Brian Gardner is the team leader of the Transportation Systems and Performance team in the Office of Planning at the Federal Highway Administration.
Jeff 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 utilize the multi-resolution modeling (MRM) methodology which integrates dynamic traffic assignment (DTA) into the operational planning and long-range planning process. He pioneered the development of two conversion tools that integrates two well known simulation models. The DynusT (mesoscopic) to VISSIM (microscopic) converter used for operational planning and the VISUM (macroscopic) to DynusT (mesoscopic) converter aimed at utilizing DTA in long-range travel demand model forecasting.
Mr. Shelton will discuss Multi-Resolution Modeling: Incorporating Dynamic Traffic Assignment into Operational Planning Projects. This presentation is aimed at providing insight into the multi-resolution modeling (MRM) concept, how and why dynamic traffic assignment was utilized in case studies, and the various challenges that were overcome during the calibration process including traffic control, temporal and spatial analysis during peak hours, network loading, and the consistency during the conversion process.
