Traffic Analysis Toolbox Volume XIV: Guidebook on the Utilization of Dynamic Traffic Assignment in Modeling

Overview

The use of Dynamic Traffic Assignment (DTA) in transportation modeling is an emerging analysis approach around the world. The benefits of applying DTA in transportation analysis increase with network size and level of congestion. This guidebook presents principles and direction that can be consistently applied when using DTA regardless of application platforms or software packages.

The major benefit of using DTA is the capability of the modeling method to take into account the spatial and temporal effects of congestion in determining route choice, time of departure choice, and mode choice. DTA is suitable for analyses involving incidents, construction zones, Active Transportation and Demand Management (ATDM) strategies, Integrated Corridor Management (ICM) strategies, Intelligent Transportation Systems (ITS), and other operational strategies, as well as capacity increasing strategies.

The purpose of this guide is to provide practitioners with guidance on how to apply DTA within transportation models. This guide provides a set of proven approaches to model building, calibration, and alternatives analysis.

The intended audience for this guidebook includes practitioners, program managers, and software developers. The first four chapters will be of primary interest to program managers while the entire guidebook will be useful to practitioners. Software developers should consider this guide when preparing documentation for their modeling software and providing instruction to their customers.
