This book was released on 1978 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geometric design standards have not been developed specifically for low volume roads. Design standards and criteria are extrapolated from higher standard roadways that are often not relevant to low volume roads. Safety is a primary criterion used for selection of design standards along with economic, financial, social and environment factors. This study attempts to determine trade-offs of various design standards and designs based on safety and economic criteria. It also summarizes existing geometric design standards that are employed by federal, state and county governments. A methodology for selection of design standards for low volume roads employing safety criteria is developed. The study approach is based on data and relationships from previous research. Accident costs cited by National Safety Council are adopted for analysis. Procedures are developed to determine the balance between design standards and accident costs. Ten-foot lane width and two-foot shoulder width are found to be reasonable for low volume situations. Horizontal and vertical alignments affect safety, vehicle running costs and travel times. Guardrail warrants of low volume roads differ from that of high volume roads. The balance and trade-offs between guardrail installation cost and accident cost expected for a given embankment geometry are evaluated. The balance between a clear zone from the edge of pavement and the accident cost savings has also been developed. It is recommended that a comparison between the accident savings due to roadway improvement and the incremental construction cost must be made to evaluate safety and economy effectively. An approach to evaluate the level of safety relative to design is developed for decision making.

Available in PDF, EPUB and Kindle. Book excerpt: TRB's National Cooperative Highway Research Program (NCHRP) Report 672: Roundabouts: An Informational Guide - Second Edition explores the planning, design, construction, maintenance, and operation of roundabouts. The report also addresses issues that may be useful in helping to explain the trade-offs associated with roundabouts. This report updates the U.S. Federal Highway Administration's Roundabouts: An Informational Guide, based on experience gained in the United States since that guide was published in 2000.

Download or read book Artificial Intelligence In Highway Location And Alignment Optimization Applications Of Genetic Algorithms In Searching Evaluating And Optimizing Highway Location And Alignments written by Min-wook Kang and published by World Scientific. This book was released on 2020-08-14 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph provides a comprehensive overview of methods for searching, evaluating, and optimizing highway location and alignments using genetic algorithms (GAs), a powerful Artificial Intelligence (AI) technique. It presents a two-level programming structure to deal with the effects of varying highway location on traffic level changes in surrounding road networks within the highway location search and alignment optimization process. In addition, the proposed method evaluates environmental impacts as well as all relevant highway costs associated with its construction, operation, and maintenance. The monograph first covers various search methods, relevant cost functions, constraints, computational efficiency, and solution quality issues arising from optimizing the highway alignment optimization (HAO) problem. It then focuses on applications of a special-purpose GA in the HAO problem where numerous highway alignments are generated and evaluated, and finally the best ones are selected based on costs, traffic impacts, safety, energy, and environmental considerations. A review of other promising optimization methods for the HAO problem is also provided in this monograph.
