This overview of the development of the barrier separated high occupancy vehicle (HOV) lane network in Houston, Texas, describes how the Metropolitan Transit Authority of Harris County (METRO) came to realize that, while they were on their way to a future rail line, they had unintentionally come upon a successful transportation system. Not only was the HOV network reducing congestion levels, but it had the flexibility necessary to respond to commuter desires as well as management objectives. Today managing the assets of the HOV lanes has become a major part of the system-wide solution for Houston's traffic problems. The HOV network has almost 65 miles currently in operation, with an additional 40 miles under construction or in design. Combined with Houston's bus system, the HOV network carries more passengers than the bus and rail systems of San Diego or Miami or Atlanta. The system operates at a cost-per-passenger mile of about $0.05 per mile. Looking toward the future, one of the most important ways Houston is going to maximize its HOV lane assets is by employing intelligent vehicle highway system (IVHS) management tactics. A number of projects, some of which are briefly described, are underway in this area. In conclusion, it is pointed out that the cooperative efforts of the various transportation agencies have been essential to evaluating the best use of the total transportation assets of Houston and Harris County, and have pointed Houston in the direction of HOV lanes as its organizing principle. |
