A Primer for Dynamic Traffic Assignment

Abstract

This publication is the result of a volunteer effort of the Transportation Research Board’s ADB30 Transportation Network Modeling Committee members and friends and is intended as a resource reference for transportation professionals who are interested in the general concept and modeling approaches of Dynamic Traffic Assignment (DTA). DTA is a general term encompassing a variety of problem definitions, formulations, and algorithmic solution procedures. The authors strove to present DTA in a model/implementation independent manner; however, due to page and resource limitation, not all DTA model variations are included in this publication. This publication does not endorse any specific DTA definition, discuss how to select a DTA model that best serves the intended application, or solution algorithm implementation, nor does it provide specific guidelines or best practice in applying DTA. Nonetheless, it is inevitable that certain discussions may exhibit judgmental expressions and opinions. Opinions expressed in this publication represent those of the authors not those of Transportation Research Board (TRB). -
