Return the traffic control indication–but if the TCD is not static, the current indication in the traffic light object is returned.

virtual DtString DtTrafficControlDevice::indicationString ( DtTrafficControlIndication  ind ) const

The set function sets the indication member variable, but if the TCD is not static the current indication will come from the traffic light anyway.

virtual bool DtTrafficControlDevice::isStatic ( ) const

virtual

Access to the isStatic member variable.

Access for the traffic light object:

virtual void DtTrafficControlDevice::setTrafficLightObject ( DtVrfObject *  trafficLight )

virtual

virtual double DtTrafficControlDevice::positionAlongLane ( ) const

virtual

The position along the lane where this traffic control device takes effect.

Generally this will be at a stop line, not at the signal/sign.
