This report represents a Phase III effort to design and evaluate a new sign design for incident route trailblazing. The colors evaluated were fluorescent coral, fluorescent purple, fluorescent yellow-green, and non-fluorescent purple. The results indicate no significant differences in driving performance with regard to the four experimental sign color combinations. Regarding the subjective preference questionnaires, significant questionnaire results along with trend information suggest that black on fluorescent yellow green was the most preferred by younger and older drivers during both day and night visibility conditions. Nonetheless, this sign color has been assigned by FHWA for pedestrian, school, and bicycle crossings, which eliminated the opportunity to use fluorescent yellow-green as a unique sign color for trailblazing in incident management situations. Preference for non-fluorescent yellow on purple consistently increased at night when the sign became more luminant; however, the overall preference for this sign color combination was lower than for the other sign color combinations tested in this study. With the elimination of these two signs, the remaining contenders for a unique sign color combination were black on fluorescent coral and fluorescent yellow on fluorescent purple. Black on fluorescent coral was ranked significantly higher than fluorescent yellow on fluorescent purple for visibility and for overall preference. Questionnaire trend information suggests that black on fluorescent coral was more preferred than fluorescent yellow on fluorescent purple during daytime viewing conditions and less preferred than fluorescent yellow on fluorescent purple during nighttime viewing conditions. The overlay film used for the fluorescent coral sign was a first generation material that can reasonably be expected to result in improved nighttime luminance when produced in a full production run. In addition to the study results, drivers commented that the arrow on the sign was too small to determine directional information from a comfortable distance. Based on such driver comments, the research conclusions, and the federal regulations enacted since the outset of this series of experiments, the following recommendations are made: (1) black on fluorescent coral should be used as a unique incident management sign color, and (2) the directional arrow on the sign should be larger.

This report represents efforts to design and evaluate a new sign design for emergency route trailblazing in a two-part series. Study was an off-road field experiment conducted to determine the best sign color combination, letter stroke width, and letter size for the emergency sign. Based upon the results of that first study, three color combinations were chosen for testing (black on coral, black on light blue, and yellow on purple) against a baseline color combination of black on orange. The test signs to be further tested featured D series, 125-mm (5 in) height letters. Study 2 was conducted using an instrumented vehicle and survey questionnaire through a construction zone-related detour. The independent variables of interest were sign color combination, age, and visibility condition. The findings of Study 2 indicated that use of a color combination other than the traditional orange background with a black legend will improve driver performance and safety when used for trailblazing during critical incidents. Based on the conclusions and other anecdotal evidence, the following recommendations were made: 1. Do not use a black on orange sign for trailblazing around a critical incident if an existing detour/construction zone is in place. 2. Do not use a black on coral sign for trailblazing around a critical incident. 3. A black on light blue sign is recommended due to its generally favorable subjective ratings and for minimization of the number of turn errors made by drivers in an overlapping detour. 4. Despite recommendation 3, it is important to note that the black on light blue sign fades to take on the appearance of a regulatory sign when headlights reflect onto it. 5. If the black on light blue sign is deemed inappropriate due to its appearance as a regulatory sign at night, consider using the yellow on purple color combination. In this study, the yellow on purple sign color combination resulted in fewer turn errors than black on orange and it was generally rated favorably by drivers, especially younger drivers.

This project entailed the design, development, testing, and evaluation of intersection decision support (IDS) systems to address straight crossing path (SCP) intersection crashes. This type of intersection crash is responsible for more than 100,000 crashes and thousands of fatalities each year. In developing these IDS systems for both signalized and stop-controlled intersections, a top-down systems approach was used that determined the necessary system functions and evaluated the capability of different technologies to perform those functions. Human factors tests were also conducted that evaluated the effectiveness of warning algorithms and infrastructure-based driver-infrastructure interfaces in eliciting a stopping response from drivers about to be involved in an SCP intersection crash. Results indicated that further technological development is needed for the sensing and intersection state IDS functions. Furthermore, infrastructure-based warning interfaces tested were greatly outperformed by previously-tested in-vehicle warnings. Thus, future research on IDS systems should focus on their infrastructure-cooperative configuration, where the system supports an in-vehicle warning.

Journalist Ian Plenderleith's Rock 'n' Roll Soccer presents the raucous history of the hype and chaos surrounding the rapid rise and cataclysmic fall of the NASL. The North American Soccer League - at its peak in the late 1970s - presented soccer as performance, played by men with a bent for flair, hair and glamour. More than just Pelé and the New York Cosmos, it lured the biggest names of the world game like Johan Cruyff, Franz Beckenbauer, Eusebio, Gerd Müller and George Best to play the sport as it was meant to be played-without inhibition, to please the fans. The first complete look at the ambitious, star-studded NASL, Rock 'n' Roll Soccer reveals how this precursor to modern soccer laid the foundations for the sport's tremendous popularity in America today. Bringing to life the color and chaos of an unfairly maligned league, soccer journalist Ian Plenderleith draws from research and interviews with the men who were there to reveal the madness of its marketing, the wild expectations of businessmen and corporations hoping to make a killing out of the next big thing, and the insanity of franchises in scorching cities like Las Vegas and Hawaii. That's not to mention the league's on-running fight with FIFA as the trailblazing North American continent battled to innovate, surprise, and sell soccer to a whole new world. As entertaining and raucous as the league itself, Rock 'n' Roll Soccer recounts the hype and chaos surrounding the rapid rise and cataclysmic fall of the NASL, an enterprising and groundbreaking league that did too much right to ignore.

In Permanent Present Tense Suzanne Corkin tells the incredible story of the amnesiac Henry Gustave Molaison - known only as H.M. until his death in 2008 - and what he taught medical science, neuroscience and the world. In 1953, at the age of twenty-seven, Molaison underwent an experimental psychosurgical procedure intended to alleviate his debilitating epilepsy. The outcome was devastating - when Molaison awoke he was unable to form new memories and for the rest of his life would be trapped in the moment. But Molaison's tragedy would prove a gift to humanity, illuminating functions and structures of the brain and revolutionizing the neuroscience of memory. His amnesia became a touchstone for memory impairment in other patients. For nearly five decades, distinguished neuroscientist Suzanne Corkin studied Molaison and oversaw his care. Her account of his life and legacy in Permanent Present Tense reveals an intelligent man who, despite his profound amnesia, was altruistic, friendly, open, and humorous. She explores how his case transformed an entire field, helping to address eternal questions. How do we store and retrieve memories? How do we know that there are different kinds of memory, controlled by different brain circuits? Is our identity bound up with remembering? If you can recall people or events for only a few seconds and cannot learn from the past or plan the future, can you still live a meaningful life? Permanent Present explores the astonishing complexity of the human brain with great clarity, sensitivity, and grace, showing how one man's story challenged our very notions of who we are. Suzanne Corkin is Professor of Behavioral Neuroscience and head of the Corkin Lab at MIT. The author of nine books, Corkin lives in Charlestown, Massachusetts. 'A fascinating account of perhaps the most important case study in the history of neuroscience, rich with implications for our understanding of the brain, our experience, and what it means to be human' Steven Pinker, author of 'How the Mind Works' and 'The Stuff of Thought' 'The best way to understand memory is to witness the ways it can disassemble. In this remarkable book, Suzanne Corkin gifts us with a rare insider's view, revealing how a man who could not remember his immediate past so profoundly influenced science's future' David Eagleman, neuroscientist and New York Times-bestselling author of 'Incognito: The Secret Lives of the Brain' 'Suzanne Corkin has written an enjoyable and sensitive story of H.M.'s life and what it has taught us about memory. Millions of patients have been the source of advances in science but few are celebrated as individuals. We learn through H.M. that 'Our brains are like hotels with eclectic arrays of guests-homes to different kinds of memory, each of which occupies its own suite of rooms' Philip A. Sharp, Institute Professor, Massachusetts Institute of Technology, and winner of the Nobel Prize in Physiology or Medicine 'Drawing on her unique investigations over more than four decades, neuroscientist Suzanne Corkin relates the fascinating story of how one severely amnesic man transformed our understanding of mind, brain, and memory' Howard Gardner, author of 'Multiple Intelligences'
