Active Traffic Management (ATM) strategies have become more common in the United States as state departments of transportation grapple with increasing congestion and fewer dollars available to add capacity to keep pace. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 286: Principles and Guidance for Presenting Active Traffic Management Information to Drivers develops and details principles and guidance for presenting drivers with dynamic information that can be frequently updated based on real-time conditions. These principles and guidance should improve the effectiveness of ATM strategies, which include systems to manage congestion, incidents, weather, special events, and work zones.

The progress that has been made in developing the positive guidance concept is documented, and the meaning of positive guidance, the philosophy of driver performance upon which it is based the nature of the driving task at those locations where positive guidance is applicable, and a procedure for its application are discussed. This report describes what must be done to improve the information system at hazardous locations. Positive guidance which is an information system matched to the facility characteristics and driver attributes, is based on the premise that a driver can be given sufficient information where he needs it and in the form that he can best use to avoid hazards.

This book examines wayfinding from a broad public health perspective and articulates what needs to be done to create better wayfinding for all people regardless of age, ability, or mode of transportation. Addressing both science and the human experience, the book brings together a group of international experts to examine community wayfinding from a variety of viewpoints. It first presents a critical foundation for understanding wayfinding from an individual perspective. Next, it describes relevant design principles and practices by drawing upon architecture, environmental graphic design, universal design (UD), and urban planning. The book then goes on to examine wayfinding tools and innovative technologies ranging from maps to apps to complex systems. In addition, coverage includes case studies, lessons from wayfinding improvement initiatives, and recommendations for future research, practice, and policy. /div Overall, the book focuses on the economic and commercial benefits of good wayfinding, its potential impact on the health of individuals and communities, as well as strategies for the journey ahead. It will appeal to numerous professionals across many disciplines from architecture and cartography to public health and urban planning. Additionally, the book can help advance a dialogue among those interested in enhancing the livability of their communities.

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.

Active traffic management (ATM) incorporates a collection of strategies allowing the dynamic management of recurrent and nonrecurrent congestion based on prevailing traffic conditions. These strategies help to increase peak capacity, smooth traffic flows, and enhance safety on busy major highways. This final report describes a series of experiments that developed and tested alternative signs focusing on lane control signs (LCS) and variable speed limit (VSL) signs and used the deployments in Minnesota and Washington as inputs to sign development. Laboratory and field studies determined both the comprehension of the ATM signs as well as their respective legibility distances. Two driving simulator studies helped determine how motorists responded to these signs in a simulated driving environment. Research results are discussed for the various studies, including legibility distances, driver behavior, speed selection, and visual clutter with respect to the used of the LCS and VSL signs.

Navigation and Intelligent Transportation Systems contains 40 papers covering the technical and functional aspects of these systems including: 3D mapping, route guidance, cellular phone access, electronic compasses, and the history and future of navigation systems. The book also covers the important role of navigation in Intelligent Transportation Systems concerned with traffic management, traveler information, vehicle control systems, commercial vehicle operations, and public and rural transportation systems. The book concludes with a chapter on the Intelligent Vehicle Initiative, a joint program between the National Highway Traffic Safety Administration, the Federal Highway Administration, and the Federal Transit Administration.
