public class ContourPlotDelay extends AbstractContourPlot<org.djunits.value.vdouble.scalar.Duration>
Contour plot for delay.

A note on the unit "/km". This unit is derived by measuring the total delay over a cell in space-time, which gives an SI value in [s]. With varying granularity, the value needs to be normalized to space-time. Hence, the value is divided by the length of the cell [m], and divided by the duration of the cell [s]. This gives a unit of [s/s/m] = [1/m]. This means that a traffic state represented by a value of D/km, gives a total amount of delay equal to D * x * t, where x * t is the size of the cell, and the resulting value is in the same unit as t. So if D = 50/km, then measuring this state over 2km and during 3 hours gives 50 * 2 * 3 = 300h of delay.

      public ContourPlotDelay(String caption, ContourDataSource source)
      Constructor. In case this plot is created live, the sampler of the sample data in the data source needs to have the extended data type ReferenceSpeed.INSTANCE registered.
      Parameters:
      caption - caption
      source - source pool
