Example 1 with TimeIntervalBean

use of org.onebusaway.transit_data.model.TimeIntervalBean in project onebusaway-application-modules by camsys.

the class ArrivalAndDepartureServiceImpl method computePredictedDepartureTimeInterval.

private TimeIntervalBean computePredictedDepartureTimeInterval(ArrivalAndDepartureInstance instance, BlockLocation blockLocation, long targetTime) {
    BlockStopTimeEntry blockStopTime = instance.getBlockStopTime();
    StopTimeEntry stopTime = blockStopTime.getStopTime();
    // interval
    if (stopTime.getDepartureTime() <= blockLocation.getEffectiveScheduleTime())
        return null;
    ScheduleDeviationSamples samples = blockLocation.getScheduleDeviations();
    if (samples == null || samples.isEmpty())
        return null;
    double mu = InterpolationLibrary.interpolate(samples.getScheduleTimes(), samples.getScheduleDeviationMus(), stopTime.getDepartureTime(), EOutOfRangeStrategy.LAST_VALUE, EInRangeStrategy.INTERPOLATE);
    double sigma = InterpolationLibrary.interpolate(samples.getScheduleTimes(), samples.getScheduleDeviationSigmas(), stopTime.getDepartureTime(), EOutOfRangeStrategy.LAST_VALUE, EInRangeStrategy.INTERPOLATE);
    long from = (long) (instance.getScheduledDepartureTime() + (mu - sigma) * 1000);
