====Whole road HOV====
All travel is HOV only on the road. Non-HOV travel is not available adjacent parallel path (lane or segment). Waze will only route on this road if the person acknowledges that they meet the HOV requirement (and
transducer if required) for this trip. There are not very many implementations of this type of set up. Example is I-66 inside the beltway in Northern Virginia; morning rush hour traffic is HOV-2+ only for eastbound traffic.
