Constructor Detail

TrafCOD

public TrafCOD(String controllerName,
               String trafCodURL,
               Set<org.opentrafficsim.road.network.lane.object.trafficlight.TrafficLight> trafficLights,
               Set<org.opentrafficsim.road.network.lane.object.sensor.Sensor> sensors,
               nl.tudelft.simulation.dsol.simulators.DEVSSimulator<org.djunits.value.vdouble.scalar.Time,org.djunits.value.vdouble.scalar.Duration,org.opentrafficsim.core.dsol.OTSSimTimeDouble> simulator)
        throws Exception

Parameters:
