    public class ContourPlotDelay
extends AbstractContourPlot<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.

    • Constructor Detail

      • ContourPlotDelay

        public ContourPlotDelay​(String caption,
                        OTSSimulatorInterface simulator,
                        ContourDataSource<GtuData> dataPool)
        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 - String; caption
        simulator - OTSSimulatorInterface; simulator
        dataPool - ContourDataSource<GtuData>; data pool
