● Compatibility with other plans
HOV lanes should be part of an overall transportation plan.
Community support should be obtained for developing HOV lanes.
Intense, recurring congestion should be occurring on the freeway general-purpose
lanes.
Peak-period traffic per lane should be approaching capacity (1700 to 2000 vehicles
per hour).
During peak periods, average speeds on the freeway main lanes during nonincident
conditions should be less than 30 mi/h (48 km/h) over a distance of about 5 mi (8 km)
or more.
Compared with using the freeway general-purpose lanes, the HOV lanes should
offer a travel time savings of at least 5 to 7 min during the peak hour.
