Dynameq provides an advanced vehicle-based traffic simulation and simulation-based dynamic traffic assignment (DTA) that allows even large, congested applications to be modelled reliably within a single traffic model and at a consistent level of detail throughout the entire network.
High-performance animations provide a 3D visualization and analysis framework that can be used for clear, detailed and intuitive presentations to both technical and non-technical audiences.
Dynameq provides scalability from a single congested corridor to an entire city, all without losing detail. Vehicle trajectories over the entire network provide the transparency needed to understand what is happening, wherever it matters.
There is no need to resort to hybrid approaches in order to ensure model stability and fast runtimes. There are no boundaries to define between separate micro and meso areas of your network, nor concerns about how the choice of those boundaries may impact model results.
When you want to run demand scenarios reaching out ten, twenty, or thirty years, the adaptive traffic simulation in Dynameq keeps the traffic in your model moving, virtually guaranteeing stable, converged results even in highly congested scenarios and without sacrificing model detail.
The adaptive traffic simulation also provides new simulation outputs which identify critical bottlenecks to facilitate calibration and analysis.
Dynameq traffic simulation moves individual vehicles on lanes, with car following, lane changing and gap acceptance models and explicit signal control.
This is the only way to capture the true causes and effects of congestion – traffic signals, freeway merging and weaving, turn pockets that overflow, late merging and queue jumping – all of which have a major impact on actual traffic conditions, travel times and travel costs.
Dynameq is extensively multithreaded for up to 4x speedup on a typical DTA run, and is optimized both for lower RAM requirements and faster runtimes.
A Dynameq model for the entire city of San Francisco including all road classifications runs to dynamic user equilibrium in 50 iterations in less than 4 hours and under 14GB of RAM. More details upon request.
High-performance 3D animations illustrate detailed vehicle trajectories and traffic signal states, permitting visualization at the individual vehicle level across the entire model area. Quickly select or screenline vehicles. Use random access to instantly access any moment in time and to fast-forward, rewind or reproduce the animation at any speed.
Dynameq dynamic user equilibrium (DUE) routing reflects how real drivers make decisions based on day-to-day learning and experienced travel times by anticipating congestion on alternative routes.
Dynameq helps you streamline the process of preparing your network. Smart logic and intelligent defaults reduce the effort required to code large networks.
Dynameq provides a generalized-cost assignment which makes it easy to create fixed or time-of-day tolls by vehicle class.
Dynameq explicitly models transit-actuated signal priority and pre-emption using early/late green and phase insertion logic.
Use Dynameq’s signal plan generator to produce signals for future scenarios or to fill in information missing from existing signal plans. The signal plan generator can design phases, compute timing parameters and define and synchronize corridors.
Dynameq includes lots of other desktop features and productivity tools designed to keep your project moving:
