The Global Street Design Guide is a timely resource that sets a global baseline for designing streets and public spaces and redefines the role of streets in a rapidly urbanizing world. The guide will broaden how to measure the success of urban streets to include: access, safety, mobility for all users, environmental quality, economic benefit, public health, and overall quality of life. The first-ever worldwide standards for designing city streets and prioritizing safety, pedestrians, transit, and sustainable mobility are presented in the guide. Participating experts from global cities have helped to develop the principles that organize the guide. The Global Street Design Guide builds off the successful tools and tactics defined in NACTO's Urban Street Design Guide and Urban Bikeway Design Guide while addressing a variety of street typologies and design elements found in various contexts around the world.

This guide was written as a quick primer for transportation professionals and analysts who assess the impacts of proposed transportation actions on communities. It outlines the community impact assessment process, highlights critical areas that must be examined, identifies basic tools and information sources, and stimulates the thought-process related to individual projects. In the past, the consequences of transportation investments on communities have often been ignored or introduced near the end of a planning process, reducing them to reactive considerations at best. The goals of this primer are to increase awareness of the effects of transportation actions on the human environment and emphasize that community impacts deserve serious attention in project planning and development-attention comparable to that given the natural environment. Finally, this guide is intended to provide some tips for facilitating public involvement in the decision making process.

The Guide provides broad statements and guidelines for highway landscape and environmental design factors considered to be properly within the scope of the Committee's interests and responsibilities. The Guide's purpose is that of developing quality, character and consistency in highways in general conformity with accepted landscape architectural principles and practices. It is intended to be used by person responsible for designing, developing and maintaining the highway landscape and environment.

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.

This synthesis presents information on current practices used by transportation agencies to complete the transportation development process (TDP). This process involves linking the planning, project development, environmental, design, construction, operations, and maintenance aspects of the overall transportation program. The purpose of the TDP is to implement a seamless process in which all these elements come together and in which there is continuous public involvement. This report will be of interest to regional and state transportation, planning, and environmental agencies who participate in the TDP and who are involved in both the development and policy aspects of the TDP. This report of the Transportation Research Board describes the history of the TDP, as well as the federal requirements that must be met under both transportation and environmental regulations. This process is made more complex by state and local regulations that must be observed in most jurisdictions. Throughout this process, as carried out by the state transportation agencies and the metropolitan planning organizations, there is continuous public involvement. Other programs, such as the transportation implementation plan, state transportation implementation plan, and environmental programs such as the National Environmental Policy Act, the Clean Air Act Amendments of 1990, and requirements of other environmental laws must be integrated into the TDP. The complexities of this process are described, and some unique approaches to meeting its demands are presented.
