The objectives of this research project are to investigate the complex and interrelated issues surrounding the safe and efficient operation of managed lanes using various operating strategies and to develop a managed lanes manual to help the Texas Department of Transportation make informed planning, design, and operational decisions when considering these facilities for its jurisdiction. This document presents three years of research in the form of a draft manual for managed lanes. It includes three chapters in draft form, which include a guide to the manual, an introduction to managed lanes, and design. This document includes research in a usable format, providing a clear, concise, and step-wise approach to planning designing, operating, and enforcing a managed lanes facility. It also refers the user to other pertinent documents which provide additional detailed information on various aspects of managed lanes.

This synthesis will be of interest to transportation planners, highway engineers, environmental personnel, highway design engineers, transit planners, highway administrators, and others concerned with the planning, design, and operational features of preferential high- occupancy vehicle (HOV) lanes on highways. Information is provided on the current and proposed state of the practice in North America. This synthesis describes the state of the art with respect to preferential treatment for HOVs on highways. This report of the Transportation Research Board provides information on long-distance facilities, such as barrier-separated, concurrent-flow (separated and nonseparated), and contraflow facilities, as well as on short-distance facilities, such as queue by-pass lanes. Planning, design, and operational features of each treatment are described. The issues and operating results are described, and specific case studies are included.

Texas cities are currently considering the managed lane concept for major freeway projects. As a new concept of operating freeways in a flexible and possibly dynamic manner, the managed lane concept has a limited experience base, thereby creating a knowledge vacuum in emerging key areas that are critical for effective implementation. . Complicating the effort is the rapid progress of several freeway improvement projects in Texas in which TxDOT is proposing managed lane operations. The operational experience both in Texas and nationally for managed lanes is minimal, particularly for extensive freeway reconstruction projects. The managed lane projects currently in existence involve retrofits of existing freeway sections within highly fixed access, geometric, and operational configurations, and established eligibility considerations. There are few projects in operation from which to draw experiential data on the implementation of managed lane freeway sections with complex or multiple operational strategies, including variations in eligible vehicle user groups by time of day. The objectives of this project are to investigate the complex and interrelated issues surrounding the safe and efficient operation of managed lanes using various operating strategies and to develop a managed lanes manual to help the Texas Department of Transportation (TxDOT) make informed planning, design, and operational decisions when considering these facilities for its jurisdiction. This document presents the critical research results obtained over the five years of this project.

This report documents the development of a decision support methodology that accomplishes two objectives: (1) sorts out the relationships between managed lanes concepts and strategies, and (2) maps the knowledge territory in order to identify gaps. In conjunction with this particular research task, a user-friendly preliminary screening tool has been developed to assist the Texas Department of Transportation (TxDOT) in identifying managed lanes strategy options very early in the conceptual planning process. The framework for the decision support methodology is the backbone for the Managed Lanes Handbook, which offers the resources and guidance to develop a managed lanes project, addressing characteristics unique to individual facilities. This report also summarizes the evolution of managed lanes in Texas over the last five years, the legislative initiatives that have shaped TxDOTs current approach to implementation, and the gaps in the knowledge base that still leave many questions unanswered. At the national level managed lanes are a relatively new and emerging concept. However, TxDOT has led the nation in research and development with two highoccupancy toll (HOT) lanes and 10 freeway high-occupancy vehicle (HOV) facilities in operation and over a dozen managed lanes projects currently under development in 10 Texas cities. Even with the experience to date, there are still many unanswered questions related to the long-term operation of managed lanes and numerous unknown factors that will require further research and documented practical experience through diligent monitoring and evaluation of facilities as they are implemented.

A managed lane facility is one that increases freeway efficiency by packaging various operational and design actions. Operating agencies may adjust lane management operations at any time to better match regional goals. However, as a new concept in operating freeways, managed lanes has a limited experience base, creating a knowledge vacuum in emerging key areas that are critical for effective implementation. The potential complexities associated with user groups and operational options will require agencies to have an appropriate number of qualified staff to ensure adequate oversight of operations and to ensure satisfactory customer service to the users. Thus, the task documented in this report identifies those staffing needs related to operational options and training that might be required to ensure those staff are fully prepared to perform their duties to the satisfaction of both the agency and the customer. Other issues addressed are the roles of job positions within the framework of managed lanes, the competencies required of those positions, and accessibility to appropriate training, education, and technical assistance to ensure these needs are met.
