The Evolution of Transport Planning
Dynameq™ includes comprehensive analysis capabilities for model calibration, validation and reporting.
Path sets and route-choice decisions can be inspected for use in calibration. Time Series and Scattergram plots are just a click away from the network visualizations. Traffic data can also be exported from Dynameq for inclusion in external tools and reports.
Path results provide a view into the route-choice behavior of drivers. Big-picture path results are critical for calibration activities and provide context for more detailed analyses. Path-based results are presented as time-dependent animations, and change over departure intervals.
Path Animation

Each used path from centroid 25 to centroid 600 is displayed on the network by color. Dynamic traffic assignment results can be extremely sensitive to route-choice, so it is important to understand how path choice varies over departure interval. Path-based analysis can provide invaluable insight into calibration efforts.

Realistic Route-Choice

The relative thickness of bars represents demand for the paths. In a dynamic user equilibrium traffic flow is assigned in such a way that the travel times among used paths between each origin-destination pair are equivalent (within each departure interval).

Flow-Density Time Series

The slope of the triangular flow-density relationship is determined by link free speed and vehicles' effective lengths and response times along a link. The coloured points correspond to measurements across lanes. Congestion is represented by the right side of the triangle. The left side is the free-flowing, uncongested regime. When congestion occurs, as on this link, points appear inside the triangle because the density measures are time-averages of the congested and uncongested regimes that occur during the statistics collection interval.

Scattergram Time Series

Scattergram plots show the impact of a demand increase on turning movement counts. Built-in regression statistics offer quick metrics for comparison. Network link and movement attributes are automatically configured on request from traffic assignment results. User-defined attributes can be created on demand. As with all other Dynameq plots, Scattergrams are presented as a time-series to show temporal effects.

In addition to comprehensive analysis tools, Dynameq offers innovative visualizations to help analysts turn mountains of data into actionable information for use in decision-making.
