Book Description
Much of the progress made in advancing the state of the practice in performance monitoring and evaluation has considered general freeway facilities and lacks specificity for managed lane facilities. Managed lane facilities are unique, typically requiring a higher degree of active (sometimes real-time) management, addressing goals and objectives that are inconsistent with the general freeway facility (i.e., revenue generation, person throughput), and accessing an exclusive set of management tools (i.e., gate closures). To address these potential differences between facilities, this investigation was conducted to isolate and document the best performance monitoring and evaluation practices and principles explicitly for managed lane facilities. Despite the novelty of managed lanes as a traffic management strategy, the diversity of managed lane facility types, and the breadth of motivating factors for managed lane implementation, some general consistency in practice was observed with respect to performance monitoring and evaluation. Common goals, objectives, and performance measures were observed across similar facility types. Significant differences were also observed across similar facility types with respect to observed performance outcomes and evaluation methodologies. Differences in observed performance outcomes are likely explained by the variety in facility design (i.e., length of facility, accessibility, etc.) and operation (i.e., eligibility requirements, toll rates, etc.), even within a similar facility type. Differences in the evaluation methodologies used to arrive at these observed performance outcomes are likely reflective of the a vailable resources for analysis at the time of evaluation and the evolving state of analysis methodologies.

Book Description
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.

Book Description
"These guidelines are intended for transportation practitioners involved in the planning, design, and operation of congestion-pricing projects. They will help agencies select or develop measures to evaluate these projects, collect the necessary data, track performance, and communicate the results to decision makers, users, and the general public. These guidelines will be valuable to all agencies who are using or considering congestion pricing to manage their roadway capacity."--Foreword.

Book Description
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.

Book Description
This report documents and presents the results of a study for evaluating the performance of Managed Lane (ML) facilities on freeways. A methodological framework is for analyzing freeway facilities with ML and General Purpose (GP) lanes operated in parallel. The framework acknowledges that the composition and behavior characteristics of the ML traffic stream are expected to be quite different from those for the GP lanes in terms of traffic volume, free-flow speed, capacity, vehicle type, etc. It further considers that there may still be certain levels of interactions between these two lane groups, especially for those facilities that do not have physical (barrier) separations, either en route or at access points, between them. Within that framework, different modules were developed based on sensor-measured or simulation-generated data, including the characterization of ML speed-flow relationship, the frictional effect of adjacent lane traffic speed, the adjustment for cross-weave effects, and the development of side-by-side facility-wide ML and GP performance measures. Thus, the proposed methodology is sensitive to different GP and ML segment types (basic, weaving, etc.) and separation styles (none, buffer, barrier), and is capable of analyzing extended facilities across multiple time periods.
