TRE is a software for the computation of dynamic assignment where path choices and demand loading depend on the travel times obtained through any network simulation model which assumes the resulting node splitting rates.
TRE bridges the gap between scientific Dynamic Traffic Assignment solutions and user friendly off-the-shelf assignment. With TRE you can see how the traffic flows and travel conditions evolve in time for your network which was static just seconds before.
Specifically, the propagation of traffic flows is based on the GLTM - General Link Transmission Model, a macroscopic engine for dynamic network loading that implements the kinematic wave theory. Through the fundamental diagram on links and comprehensive Junction Model (with signal plans, priorities and conflict areas) at nodes, the GLTM is capable of reproducing the main congestion phenomena on road links (queues, spillback, hypocritical friction) and at intersections, either signalized or not (spillback, conflicting maneuver congestion, signal delays and capacity reductions, merging congestion, ...).
The implementation of the software is completely parallelized so as to maximize performances by fully exploiting the available computing resources. Thanks to that, dynamic assignment on a real-scale network can be computed in reasonable time. But significant reduction of computation times didn’t mean oversimplifying, quite opposite: TRE is shipped with detailed traffic flow model, powerful junction model and time discretization can be reduced up to one second.
Besides being truly scientific academic solution with advanced algorithms, TRE is user friendly and fully integrated with PTV Visum, seamlessly adding dynamics to your network just like any other assignment method:
NetViewer, an advanced GIS-based viewer included with the Add-in, allows to explore the results of TRE assignments (inflows, outflows, travel times, vehicular densities, speeds, queues and capacities) in form of flow diagrams on the map for different results time interval (colors and thickness are completely customizable), or as temporal profiles for single links. With NetViewer you can play a “movie” of your network simulation going back and forth in a simple mouse wheel action!
