Class DvrpOfflineTravelTimeEstimator

java.lang.Object

org.matsim.contrib.dvrp.trafficmonitoring.DvrpOfflineTravelTimeEstimator

All Implemented Interfaces:

EventListener, DvrpTravelTimeEstimator, org.matsim.core.api.internal.MatsimExtensionPoint, org.matsim.core.mobsim.framework.listeners.MobsimBeforeCleanupListener, org.matsim.core.mobsim.framework.listeners.MobsimListener, org.matsim.core.mobsim.qsim.components.QSimComponent, org.matsim.core.router.util.TravelTime

public class DvrpOfflineTravelTimeEstimator
extends Object
implements DvrpTravelTimeEstimator, org.matsim.core.mobsim.framework.listeners.MobsimBeforeCleanupListener

Used for offline estimation of travel times for VrpOptimizer by means of the exponential moving average. The weighting decrease, alpha, must be in (0,1]. We suggest small values of alpha, e.g. 0.05.

The averaging starts from the initial travel time estimates. If not provided, the free-speed TTs is used as the initial estimates
