Download or read book Exclusive Lanes for Trucks and Passenger Vehicles on Interstate Highways in Virginia written by Lester A. Hoel and published by . This book was released on 1997 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increases in heavy truck traffic on Virginia's highways in recent years have raised concerns about both safety and capacity, particularly on the interstate system. Transportation agencies have developed a number of strategies for dealing with the impacts on safety and capacity of a truck population that has been increasing in volume and in the percentage of large tractor-trailers. One strategy that has been suggested is separate lanes for trucks and passenger vehicles. A reliable methodology to determine when separate lanes for trucks and passenger vehicles are economically feasible would enable transportation officials to make informed decisions concerning when this approach should be considered and used. This study evaluated a computer program, Exclusive Vehicles Facilities (EVFS), developed by the Federal Highway Administration for determining the economic feasibility of separating trucks and other vehicles on freeway segments. A 50.7-km (31.5-mi) segment of 1-81 in Virginia was selected to demonstrate the application of the program. A number of factors contribute to the feasibility of exclusive lanes. Although no single factor predominates, traffic volume, vehicle mix percentage, accident rates, and maintenance and construction costs are given more weight than other factors in the program. Among the program's strengths are its ability to analyze a number of alternatives for a variety of different conditions, its ease of use, and the fact that it can be inexpensively applied. Its weaknesses include its inability to differentiate between the lane(s) (i.e., inside, middle, outside) to which restrictions are applied and its unsuitability for analyzing exclusive lane alternatives in which a barrier is used to separate vehicle types. With respect to 1-81, several exclusive lane strategies produced a benefit-cost ratio greater than 1.0 and a net present worth in the millions of dollars. Should 1-81 or another high-volume interstate corridor with a large truck percentage be considered for improvement, VDOT should apply EVFS to assist in evaluating the feasibility of exclusive lane alternatives. Since EVFS is designed to perform economic analyses, operational and geometric implications of any exclusive lane strategy should also be considered.

Available in PDF, EPUB and Kindle. Book excerpt: NCHRP Report 649/NCFRP Report 3: Separation of Vehicles - CMV-Only Lanes presents an extensive compendium of information about CMV-only lanes and examines major issues and concepts that should be understood in developing new applications of CMV-only lane concepts as a potential method for both easing congestion and reducing the number of traffic accidents on highways. Appendices to this report, including an annotated literature review, performance evaluation criteria, benefits monetization factors and unit costs, and net present value calculations for benefit-cost analysis, are available on the TRB website. This report and the supplemental information can be used by public agencies that may be considering CMV-only lane concepts in corridor studies or other planning applications. The report provides data such agencies can use to support their own evaluations of CMV-only lane projects.

Download or read book Issues of the Day written by Ian W.H. Parry and published by Routledge. This book was released on 2010-09-23 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: Issues of the Day provides an easy way for students, academics, journalists, policymakers, and the public to learn about a diverse range of policy issues affecting the environment, energy, transportation, and public health. Each commentary gives a short assessment of a topic, summarizing in a non-technical way the current state of analysis or evidence on the issue, along with selected recommendations for further reading. The essays are written by world renowned scholars, mostly economists, and provide useful insights on policy problems that are often complex and poorly understood. Some of the topics covered include air pollution, hazardous waste, voluntary environmental programs, domestic (U.S.) and global climate policy design, fishery management, water quality, endangered species, forest fires, oil security, solar power, road and airport, fuel taxes and fuel economy standards, alternative fuel vehicles, health and longevity, smoking, malaria, tuberculosis, and the environment and development. The objective is to disseminate the findings of sound, objective research on the costs, benefits, and appropriate reform of public policies. The book provides a useful supplement for undergraduate- and graduate-level course reading, a reference guide for professionals, and a way for the general reader to quickly develop an informed perspective on the most important policy problems of the day. Issues of the Day is available to download as a PDF from the Resources for the Future website: www.rff.org/weeklycommentary

Download or read book Assessing and Managing the Ecological Impacts of Paved Roads written by National Research Council and published by National Academies Press. This book was released on 2006-01-22 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: All phases of road developmentâ€"from construction and use by vehicles to maintenanceâ€"affect physical and chemical soil conditions, water flow, and air and water quality, as well as plants and animals. Roads and traffic can alter wildlife habitat, cause vehicle-related mortality, impede animal migration, and disperse nonnative pest species of plants and animals. Integrating environmental considerations into all phases of transportation is an important, evolving process. The increasing awareness of environmental issues has made road development more complex and controversial. Over the past two decades, the Federal Highway Administration and state transportation agencies have increasingly recognized the importance of the effects of transportation on the natural environment. This report provides guidance on ways to reconcile the different goals of road development and environmental conservation. It identifies the ecological effects of roads that can be evaluated in the planning, design, construction, and maintenance of roads and offers several recommendations to help better understand and manage ecological impacts of paved roads.

Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
