High-occupancy-vehicle (HOV) lanes were first introduced into the Phoenix metropolitan area freeway system with the opening of I-10 west of I-17. The system now contains approximately 27 mi (43 km) of freeway with HOV priority lanes. The system will include approximately 40 mi (64 km) of freeway with HOV lanes by the year 2000. A study was undertaken to field evaluate the operation of HOV lanes in the Phoenix metropolitan area to examine the use of HOV lanes, priority-lane violation rates, and the overall effectiveness of HOV lanes in the Phoenix metropolitan area. The results showed that HOV lanes become very effective in periods of high congestion on the adjacent freeway lanes. It appears that freeways with HOV lanes have much higher automobile occupancy than do freeways without HOV lanes. One possible cause of this increase in occupancy is a shift from single-occupancy vehicles to higher-occupancy modes of travel along HOV facilities. Although the Phoenix area HOV system may not, in large part, be effective by some of the more traditional measures of effectiveness, the system has been successful in encouraging higher vehicle occupancies and improving HOV travel.
