A Guide for Achieving Flexibility in Highway Design


Book Description

Context-sensitive solutions (CSS) reflect the need to consider highway projects as more than just transportation facilities. Depending on how highway projects are integrated into the community, they can have far-reaching impacts beyond their traffic or transportation function. CSS is a comprehensive process that brings stakeholders together in a positive, proactive environment to develop projects that not only meet transportation needs, but also improve or enhance the community. Achieving a flexible, context-sensitive design solution requires designers to fully understand the reasons behind the processes, design values, and design procedures that are used. This AASHTO Guide shows highway designers how to think flexibly, how to recognize the many choices and options they have, and how to arrive at the best solution for the particular situation or context. It also strives to emphasize that flexible design does not necessarily entail a fundamentally new design process, but that it can be integrated into the existing transportation culture. This publication represents a major step toward institutionalizing CSS into state transportation departments and other agencies charged with transportation project development.




Per Mollerup


Book Description

Riffing on the techie term 'wayfinding', which designers and manufacturers use when talking about the function of signs and signage systems as they are used by the viewer, this book seeks to find a more precise visual language for what sign designers actually do, which is to show the way. Unfortunately, as Mollerup points out, many designers never master the art of wayshowing themselves. For wayshowing relates to wayfinding as writing relates to reading and as talking relates to hearing - The purpose of wayshowing is to facilitate wayfinding. In this accessible but invigorating investigation, Mollerup examines international sign systems and architectural landmarks in detail with his trademark candor and good humor. His analysis is at once pithy, scholarly, and historical.




Roadside Design Guide


Book Description

This document presents a synthesis of current information and operating practices related to roadside safety and is developed in metric units. The roadside is defined as that area beyond the traveled way (driving lanes) and the shoulder (if any) of the roadway itself. The focus of this guide is on safety treatments that minimize the likelihood of serious injuries when a driver runs off the road. This guide replaces the 1989 AASHTO "Roadside Design Guide."










A Proposed Program for Scenic Roads & Parkways


Book Description

"In April 1962, Executive Order 11017 and subsequent amendments, established the Recreation Advisory Council comprised of the Secretaries of the Interior, Agriculture, Defense, Commerce, Health, Education and Welfare. the Administrator of the Housing and Home Finance Agency, and the Chairman of the Tennessee Valley Authority. The council was commissioned, among other things, to provide broad policy advice on all important matters affecting outdoor recreation resources and to facilitate coordinated efforts among the various Federal agencies. In 1964, the Council issued a policy statement (Circular No. 4) recommending that a national program of scenic roads and parkways be developed. In this policy circular, the Council identified certain elements to be considered in a comprehensive study of such a program and commissioned the Department of Commerce to conduct it."--




Gravel Roads


Book Description

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.
