Available in PDF, EPUB and Kindle. Book excerpt: he objective of this study is to examine prevailing rural design standards to determine their economic justification. This would evaluate in depth the cost of some of the most significant design practices (for example, roadway and shoulder width and surfacing type). Resulting user benefits, such as operating, accident and time savings would be weighed against the cost of individual features. In addition to the analysis of the user-benefit relationships, the economic and social consequences to local residents, businesses and communities should be studied and a suitable means of including them in the reckoning of warranted levels of improvement should be found.

Available in PDF, EPUB and Kindle. Book excerpt: "Everything that sustains us – grown, mined, or drilled – begins its journey to us on a low-volume road (Long)." Defined as roads with traffic volumes of no more than 400 vehicles per day, they have enormous impacts on economies, communication, and social interaction. Low-volume roads comprise, at one end of the spectrum, farm-to-market roads, roads in developing countries, northern roads, roads on aboriginal lands and parklands; and at the other end of the spectrum, heavy haul roads for mining, oil and gas, oil sands extraction, and forestry. Low-Volume Road Engineering: Design, Construction, and Maintenance gives an international perspective to the engineering design of low-volume roads and their construction and maintenance. It is a single reference drawing from the dispersed literature. It lays out the basic principles of each topic, from road location and geometric design, pavement design, slope stability and erosion control, through construction to maintenance, then refers the reader to more comprehensive treatment elsewhere. Wherever possible, comparisons are made between the standard specifications and practices existing in the US, Canada, the UK, South Africa, Australia and New Zealand. Topics covered include the following: Road classification, location, and geometric design Pavement concepts, materials, and thickness design Drainage, erosion and sediment control, and watercrossings Slope stability Geosynthetics Road construction, maintenance, and maintenance management Low-Volume Road Engineering: Design, Construction, and Maintenance is a valuable reference for engineers, planners, designers and project managers in consulting firms, contracting firms and NGOs. It also is an essential reference in support of university courses on transportation engineering and planning, and on mining, oil and gas, and forestry infrastructure.

Available in PDF, EPUB and Kindle. Book excerpt: This Low-Volume Roads Engineering Best Management Practices Field Guide is intended to provide an overview of the key planning, location, design, construction, and maintenance aspects of roads that can cause adverse environmental impacts and to list key ways to prevent those impacts. Best Management Practices are general techniques or design practices that, when applied and adapted to fit site-specific conditions, will prevent or reduce pollution and maintain water quality. BMPs for roads have been developed by many agencies since roads often have a major adverse impact on water quality, and most of those impacts are preventable with good engineering and management practices. Roads that are not well planned or located, not properly designed or constructed, not well maintained, or not made with durable materials often have negative effects on water quality and the environment.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This note presents the Roads Economic Decision Model (RED) that performs an economic evaluation of road investments, and maintenance options, customized to the characteristics of low-volume roads, such as: high uncertainty of the assessment of traffic, road condition, and future maintenance of unpaved roads; periods with pass disruptions; levels of service, and corresponding road user costs defined not only through roughness; high potential to influence economic development; and, beneficiaries, other than motorized road users. The model computes benefits accruing to normal, generated, and diverted traffic, as a function of a reduction in vehicle operating, and time costs, and, adopts the consumer surplus approach, which measures the benefits of road users, and consumers of reduced transport costs. RED addresses, among others, the following additional concerns: reduce input requirements for low-volume roads; consider the higher uncertainty, related to input requirements; compute internally the traffic generated due to decreased transport costs, based on a defined price elasticity of demand; and, quantify the economic costs, associated with the days per year when the passage of vehicles is further disrupted by a highly deteriorated road condition. Particularly, the model highlights all input assumptions, and comprehensively integrates them with sensitivity, switching values, and stochastic risk analysis.

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.
