| 摘要： | The research reported in this paper is an investigation of the implementation of a dynamic HOV lane. A dynamic HOV lane is an HOV lane that is converted to other uses at different times of the day or under special circumstances using ITS technologies and real-time data in order to make more efficient use of HOV facilities and improve the safety of motorists, incident responders, and HOV lane operations personnel. The development of the concept included a literature review of HOV system planning and operations, incident management, and ITS research, as well as detailed interviews with agencies that oversee HOV lane operations in cities across the United States. Information from the literature and agency interviews was synthesized and analyzed to identify barriers to implementation and critical issues. Then a hypothetical dynamic HOV lane was designed to illustrate how the HOV lane and ITS components fit together and how the barriers might be overcome to preserve the benefits associated with a dynamic HOV lane. The barriers identified were justifying the need for a dynamic HOV lane, ensuring motorists' safety, technical reliability, adequacy of data, implementation costs, public perceptions, legality, and the wide variety of contributing factors. These barriers might be overcome by investigating potential applications carefully to ensure that there is a practical problem to solve, building a reliance on HOV system technologies, proper design and placement of system components, extensive public education, maximizing technical reliability with backup systems and good maintenance, archiving data for analysis and system improvements, using dynamic HOV lane technologies for other ATMS applications, and developing policies and laws to support dynamic HOV lanes. Research findings showed a reluctance to depend on advanced technology for the accurate and safe operation of a dynamic HOV lane as described in this report. Because the fundamental difference between a dynamic HOV lane and a "normal" HOV lane is reliance upon a coordinated system of ITS technologies, it was therefore concluded that a dynamic HOV lane cannot be implemented until the dependability of its component technologies is successfully demonstrated. |
