DynusT is a simulation-based dynamic traffic assignment (DTA) software that can support engineers and planners in addressing emergent transportation planning and operations issues.

Lean & Powerful

With DynusT, engineers and planners can estimate the evolution of system-wide traffic flow dynamics patterns resulted from individual drivers seeking the best routes to their destinations responding to changing network demand, supply, or control conditions. For these reasons, DynusT has been designed with 3 goals in sight:

  1. Superior traffic simulation realism

  2. Consistent and dependent dynamic equilibrium assignment

  3. Computational efficiency

Simple to Use

DynusT is Windows-based software. DynusT is aimed at integrating with travel demand models and microscopic simulation models, supporting application areas in which realistic traffic dynamic representation is needed for a large-scale regional or corridor network. For more on what DynusT is, check the videos, projects, as well as publications that DynusT has been used.

Open Source

The DynusT Open Source Project has been created to promote and support the advancement of modeling theories and techniques to assist transportation agencies and practitioners in improved modeling and transportation policy decision making through state-of-the-art tools. It is also one of the goals of the open source project to allow university researchers to develop further dynamic traffic assignment research based on the DynusT platform.

Project by DynusT: SHRP2 ProjectR11

This project brief explores the software tool, the Work Zone Impacts and Strategies Estimator (WISE). WISE is designed to assist program managers in sequencing programs of projects. In addition, it is designed to help planners and engineers evaluate the impacts of work zones to determine strategies to reduce these impacts. The operations module uses DynusT to provide its main functionality. The concept behind the operations module is to dive deeper into the granularity of the time varying interactions occurring between traffic and the network during a work zone project. What a static model cannot capture (time-dependent congestion and diversion caused by a congestion) a simulation model such as DynusT can.

"Partnership to Develop an Integrated, Advanced Travel Demand Model with Fine-Grained, Time-Sensitive Networks: Sacramento-Area Application"

Project C10B developed an integrated, advanced travel demand model with a fine-grained time-sensitive network simulation for the Sacramento, California, region. Project C10B developed a methodology to reflect changes in the nature of demand, mode choice (including “new modes” such as work or shopping at home and nonmotorized travel), destination choice, timing, and route of travel as a response to transit service, highway network congestion, roadway management strategies, road pricing, parking policies, and other public policies aimed at reducing congestion. This was achieved by integrating the activity-based demand model DaySim and a Dynamic Traffic Assignment (DTA) model, DynusT and a transit network simulation model, FAST-TrIPs.
