Download Trade-offs Between Geometric Design Standards and Safety for Low Volume Roads Book in PDF, Epub and Kindle
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.

TRB's National Cooperative Highway Research Program (NCHRP) Report 659: Guide for the Geometric Design of Driveways explores guidelines related to the geometric design of driveways. The report includes driveway-related terms and definitions, an examination of basic geometric controls, a summary of access spacing principles, and detailed discussions of various geometric design elements. Material related to and supporting the contents of NCHRP Report 659, including an extensive review of literature, has been published as NCHRP Web-Only Document 151: Geometric Design of Driveways.

Download Low-Volume Roads Engineering - Best Management Practices Field Guide Book in PDF, Epub and Kindle
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.
