Summary

Description
English: Empirical spatiotemporal common features of traffic congestion and the associated traffic phase definitions in Kerner’s theory: (a) Measured data of average vehicle speed in time and space. (b) Representation of speed data in (a) on the time-space plane. (c-f) Time-dependences of speed (c, e) and flow rate (d, f) at two different locations within traffic congestion shown in (a, b); the data in (c, d) and (e, f) are measured respectively at location 17.1 km (c, d) (about 100 meter upstream of road location labelled “On-ramp bottleneck” in (a, b)) and at location 16.2 km (e, f). At location 17.1 the flow rate (d) in free and synchronized flows is greater in comparison with that at location 16.2 (f) due to on-ramp inflow at the bottleneck.

This graph image could be re-created using vector graphics as an SVG file. This has several advantages; see Commons:Media for cleanup for more information. If an SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.


It is recommended to name the SVG file “Asda en 2 phases.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.
