Dynamic Traffic Assignment: A Practical Approach (September 14, 2016)


Date: September 14, 2016

Description: Dynamic Traffic Assignment (DTA) promises better treatments of recurring and non-recurring traffic flow phenomena, including queue formation and spillback where volumes exceed capacity, than static traffic assignment methods to which planners are accustomed. DTA also more readily accommodates the added temporal fidelity of emergent travel demand model frameworks (e.g., tour- and activity-based models) and offers a solution for analyzing innovative congestion management strategies (e.g., advanced traffic management systems, intelligent transportation systems, and managed lanes) for which static assignments are unsuitable. Where a plethora of DTA solutions exist and have existed for some time, examples of successful applications remain uncommon. The dearth of experience with DTA in practice is largely attributable to a dearth of guidance in how to define and to achieve success when developing and applying DTA. This webinar presents a practical methodology for building and applying DTA for real planning projects, provides recommendations for defining success, and identifies some of the pitfalls and shortcuts that stand in the way of wider adoption and successful application of DTA.

Presenter: Daniel Morgan, Vice President, Caliper Corporation has been with Caliper for 14 years and is the Director of Traffic Simulation and Product Manager for TransModeler, Caliper's GIS-based traffic simulation software. Mr. Morgan specializes in traffic and transit simulation modeling and has experience developing computer applications for transportation planning, demand modeling, and traffic simulation. In recent years, Mr. Morgan has managed a wide range of projects involving the application of traffic microsimulation and simulation-based dynamic traffic assignment (DTA) to wide-area and regional networks using TransModeler.
