This book was released on 2007 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past few decades, managed lane strategies have become more prevalent in addressing congestion issues. Most of the research focused on these managed lane strategies have been based on pricing, access ability, and user classifications. In addition, these strategies have all focused on freeways, expressways, and barrier separated toll lane traffic with great success. However, there has been little research on applying these strategies to ramps.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Strategies for Interim Use of Managed Lanes written by Jodi L. Carson and published by . This book was released on 2005 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although managed lanes will largely function under their intended standard operating procedures, certain conditions (i.e., construction, special events, incidents, or emergencies) may require unusual interim use of the facilities. Because interim managed lane use may detract from the facilities' intended performance, carefully crafted interim use policies should guide these decisions. Given the lack of formal policies or guidelines, variability in observed practices and limited understanding of potential benefits or concerns surrounding interim use of managed lanes (noted through a review of published literature and observed national practice), the objectives of this task were to: (1) discern any positive procedural trends in interim managed lane use that could be recommended for widespread implementation, (2) identify and describe potential benefits and concerns surrounding interim use of managed lanes, and (3) assimilate this information into recommended guidelines addressing all aspects of managed lane facility interim use. This information forms the basis of the recommendations contained in the Managed Lanes Manual developed for TxDOT and FHW A. Following a brief introduction, this report describes motivating conditions and strategies for interim use, general considerations for interim use (i.e., operational and safety effects, public acceptance and perceptions, etc.), and national interim use practice and experience. Based on these findings, recommendations for interim use based on the: (1) severity and nature of conditions; (2) time-of-day, anticipated duration, and traffic impacts; and (3) availability of alternative facilities or strategies are provided. Recommended planning activities and requirements for implementation are also provided.

Download or read book Advanced Freeway System Ramp Metering Strategies for Texas written by Carroll J. Messer and published by . This book was released on 1993 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freeway ramp metering systems have been used to improve urban freeway flow. However, control strategies must be properly adjusted to account for ramp queues overflowing onto surface streets and provide equitable on-ramp control during various operating periods. An improved solution can be obtained by optimizing this problem simultaneously for a group of time slices. This study identifies and examines a microcomputer-based optimization scheme that can assist in developing efficient freeway control strategies for on-line freeway surveillance and control. A multi-level freeway control structure is employed for which ramp metering control algorithms are developed for each level of control. Flow-based and lane occupancy-based system algorithms are presented. Detailed data file requirements are provided for each control level. A microcomputer prototype, or laboratory test version of the system level, will be described in a companion project report.
