On behalf of Kittelson & Associates, Inc. in Oakland (formerly Dowling Associates) we are pleased to invite you to attend our new Transportation Education Series (TES) workshop. These interactive workshops focus on a wide range of topics and are intended to promote professional development and advancements in transportation engineering and planning. The sessions also provide a unique forum for transportation professionals from a wide range of public agencies to share their ideas, best practices, and challenges. Participants earn credits that can be applied to continuing education requirements. We have a wonderful opportunity lined up for you on October 29th regarding in Dynamic Traffic Assignment (DTA). Details are listed below. Beverages and lunch will be provided.
There is increasing interest in Dynamic Traffic Assignment (DTA) as a modeling tool that captures the relationship between dynamic route choice behaviors and transportation operating characteristics. Unlike static analysis tools, DTA uses time-dependent travel conditions to determine traffic assignment routes and throughput. From a traveler behavior standpoint, DTA is a tool that allows for more realistic modeling of traveler adaptation to recurrent or non-recurrent traffic congestion.
DTA is an appropriate tool for any situation where route demand patterns are influenced by operational conditions that change during the analysis period, and where network-level traffic operational performance measures are desired. DTA can be applied in isolation from other tools to estimate demand shifts and route travel time. DTA may also be used as part of an integrated modeling process where origin-destination matrices are input to a DTA model and then detailed traffic demand patterns (paths and turning movements) from the DTA are used as input to more detailed operational models such as HCM software (i.e., Synchro) or microsimulation (i.e., VISSIM, Paramics, CORSIM).
DTA modeling is most appropriate for the following types of studies:
Session attendees can expect to gain:
- A better understanding of DTA’s capabilities
- A portfolio of real-world examples where DTA was applied
- A summary of lessons learned when using DTA
- A brief introduction to DTA-Lite, an open source tool
This Transportation Education Series workshop will start promptly at 11:30 AM and will run until 1:00 PM on Tuesday, October 29. There is no cost to attend this session and the workshop is equal to 1.5 professional Development Hours (PDH). Lunch will be provided.
Mike Aronson, P.E.,Principal Engineer, Kittelson & Associates, Inc., Oakland, CA
Mike has over 30 years of experience in all aspects of transportation planning and traffic operations analysis, with a particular emphasis on travel model development and applications. He has managed transportation studies for general plans, corridor studies, rail transit extensions, Caltrans project development, and many types of development master plans. Mike has evaluated and improved traffic assignment procedures for numerous travel models, and has developed methodologies for ramp metering analysis and transfers of data between travel demand models and detailed microsimulation models. He has been involved in testing of DTA for the I-580 corridor in Alameda County and the I-80 corridor in Solano County.
Kevin Chen, P.E., Associate Engineer, Kittelson & Associates, Inc., Oakland, CA
Kevin has twelve years of experience in transportation engineering and planning. He has completed many freeway corridor and interchange projects throughout California and across US. Kevin has a thorough background in the development and application of microscopic, mesoscopic, and macroscopic simulation models, as well as working with various travel demand models to develop traffic forecasts. Kevin has recently managed several ramp metering feasibility and implementation projects, including the Solano I-80 project, which he applied CUBE Avenue (a Dynamic Traffic Assignment modeling tool), to quantify potential traffic diversion due to ramp metering, at a county-wide level.
Shaun Quayle, P.E., Senior Engineer, Kittelson & Associates, Inc., Portland, OR
Shaun focuses on traffic operations through planning, design, implementation and operations. He has used Dynamic Traffic Assignment for FHWA research projects and long-range planning projects to help inform project investment decisions based on time-dependent measures of effectiveness. Shaun is also well versed in multi-resolution modeling (e.g. travel demand model to DTA to Synchro or VISSIM) to help projects save time and resources to do detailed corridor or sub-area modeling (DTA), and intersection-level or multi-modal detailed microsimulation modeling (VISSIM).
Anxi Jia, Ph.D., Transportation Analyst, Kittelson & Associates, Inc., Reston, VA
Anxi contributed to several research projects at the Institute for Transportation Research and Education at North Carolina State University while attending graduate school at North Carolina State University. He has 5 years' work experience in Dynamic Traffic Assignment, travel modeling, and mesoscopic simulation. He was involved in two national research projects and two practical projects funded by North Carolina DOT, both of them related to Dynamic Traffic Assignment and mesoscopic simulation. His work provides transportation planners and engineers with an improved basis for assessing the impacts of various transportation projects and scenarios.
