Expectancy relates to a driver's readiness to respond to situations, events, and information in predictable and successful ways. This report describes the concept of driver expectancy in the context of the driving task, and provides examples of expectancy and expectancy violations. It includes a procedure for identifying general and specific expectancy violations to enable engineers to develop remedial treatments to deal with expectancy problems.

After several decades of research, practice, intervention, and instruction, traffic psychology is in need of a summary work outlining the main trends in the discipline. Traffic Psychology Today provides a theoretical basis of the topic, a summary of the acquired research in the field, practical applications for government planners, and a critical discussion of future trends. Through a series of chapters contributed by an international group of researchers under the general editorship of Pierre Barjonet, Traffic Psychology Today comprehensively synthesizes thinking in the psychology of traffic from its inception in the mid 1950s through the present day.

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.

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.

Winner of the 2018 CCCC Technical and Scientific Communication Award in the category of Best Book in Technical or Scientific Communication Responding to the effects of human mobility and crises such as depleting oil supplies, Ehren Helmut Pflugfelder turns specifically to automobility, a term used to describe the kinds of mobility afforded by autonomous, automobile-based movement technologies and their ramifications. Thus far, few studies in technical communication have explored the development of mobility technologies, the immense power that highly structured, environmentally significant systems have in the world, or the human-machine interactions that take place in such activities. Applying kinaesthetic rhetoric, a rhetoric that is sensitive to and developed from the mobile, material context of these technologies, Pflugfelder looks at transportation projects such as electric taxi cabs from the turn of the century to modern day, open-source vehicle projects, and a large case study of an autonomous, electric pod car network that ultimately failed. Kinaesthetic rhetoric illuminates how mobility technologies have always been persuasive wherever and whenever linguistic symbol systems and material interactions enroll us, often unconsciously, into regimes of movement and ways of experiencing the world. As Pflugfelder shows, mobility technologies involve networks of sustained arguments that are as durable as the bonds between the actors in their networks.
