The Evolution of Transport Planning
Dynameq™ enables analysts to distill mountains of data into visual representations of dynamic traffic conditions, from the big picture down to individual lane queues.
Simulation results are presented as a time-series, and animations display changing traffic conditions. Dynameq's animated plots can be customized easily to display a variety of traffic assignment results for one or more classes of traffic, including flow, density, speed, travel time, vehicle counts and queues.
Network-Wide Results

The increasing bar link widths and red node coloring towards the top of the diagram represent increased flow. This network-wide animated view identifies congestion spots at a glance. Link bar widths and colors can be customized to represent link occupancy, inflow/outflow, density, speed, travel time and vehicle counts. Node circle sizes and colors represent movement flows and counts.

Lane/Movement Animation

The warm colors show elevated occupancy by lane where vehicles are queueing behind unprotected left-turning movements or traffic light signals. Intersection movements are colored similarly. Animated movement plots provide a more detailed breakdown of results that pinpoint the congestion. Each lane and turning movement can be color-coded according to occupancy, flow, density, speed or count.

Queue results show detailed animations of queues by lane. Under congested conditions, queues spill across lanes and spill back along links and through upstream intersections. Queues clear gradually when localized demand falls below the capacity at the bottleneck.
Lane Queues

The dark red lane queues in this animated plot represent the position on the link of the last vehicle which experiences delay. Congestion builds as vehicles wait for a green phase, and left-turning vehicles wait for gaps in opposing traffic streams.

Comparisons

This comparison shows lane queue differences at a signalized intersection across a low-demand (left) and high-demand (right) scenario. Side-by-side animations address the difficulty of comparing temporal results. Scenario comparisons can be made on any Dynameq animated plot, and can be used to contrast quality of service differences due to infrastructure modifications, behavioral changes, or demand variations.

In addition to results visualization capabilities, Dynameq offers detailed analysis capabilities for model calibration, validation and reporting.
