This report provides guidance for the design and application of shoulder and centerline rumble strips as an effective crash reduction measure, while minimizing adverse effects for motorcyclists, bicyclists, and nearby residents. Using the results of previous studies and the research conducted under this project, safety effectiveness estimates were developed for shoulder rumble strips on rural freeways and rural two-lane roads and for centerline rumble strips on rural and urban two-lane roads.
This is a powerful and darkly humorous graphic polemic by a leading British comi artist that investigates our increasingly dangerous relationship with cars. If you want to get away with murder, buy a car. Combining autobiography, statisti, case histories, advertising and reportage, Woodrow Phoenix draws a compelling picture of the warped psychology behind our need for speed.
NEW YORK TIMES BESTSELLER • A candid and moving memoir of how one woman’s pregnancy forced her to confront her definition of how to live a successful life “Slyly ironic, frequently hilarious, [Martha] Beck’s memoir charts the journey from being smart to becoming wise.”—Time This edition includes a new afterword about Adam. From the moment Martha and her husband, John, accidentally conceived their second child, all hell broke loose. They were a couple obsessed with success. After years of matching IQs and test scores with less driven peers, they had two Harvard degrees apiece and were gunning for more. They’d plotted out a future in the most vaunted ivory tower of academe. But when their unborn son, Adam, was diagnosed with Down syndrome, doctors, advisers, and friends in the Harvard community warned them that if they decided to keep the baby, they would lose all hope of achieving their carefully crafted goals. Fortunately, that’s exactly what happened. By the time Adam was born, Martha and John were propelled into a world in which they were forced to redefine everything of value to them, put all their faith in miracles, and trust that they could fly without a net. And it worked. Expecting Adam captures the abject terror and exhilarating freedom of facing impending parenthood, being forced to question one’s deepest beliefs, and rewriting life’s rules.
A work of graphic nonfiction exploring the powerful, often toxic relationship between people and cars. Using the comic book format, this book vehemently dispels the notion that traffic accidents are inevitable and/or acceptable on any level, insisting that drivers own their responsibility, and consider the consequences of careless and dangerous behavior. It also addresses such timely issues as the use of cars as weapons of mass murder in places like Charlottesville, VA.
Traffic control devices applied to the pavement can provide a significant amount of information for the driver. The objective of this research was to assess the effectiveness of various pavement marking materials, devices, and treatments that have potential to increase driver awareness and safety. The following pavement marking materials, devices, and treatments were investigated as part of this research project: . yellow-green crosswalk material, . in-roadway warning lights, . fluorescent orange retroreflective raised pavement markers, . "removable" pavement marking paint, and . rumble strips. This report includes recommendations for the application of in-roadway warning lights and rumble strips. Further research is needed on the yellow-green crosswalk material, fluorescent orange retroreflective raised pavement markers, and the "removable" pavement marking paint before application guidelines can be developed.
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 339: Centerline Rumble Strips (CLRS) examines current design, installation, configuration, dimension, and visibility issues associated with CLRS. The report addresses the need for guidance on warrants, benefits, successful practices, and concerns such as external noise and the reduced visibility of centerline striping material. Also addressed are pavement deterioration, ice buildup in the grooves, adverse impact on emergency vehicles, and the effect of CLRS on bicyclists. Particular attention was paid to available before-and-after CLRS installation crash data to document the safety aspects of CLRS and the availability of policies, guidelines, warrants, and costs regarding their use and design.
This synthesis will be of interest to traffic engineers, highway design engineers, highway maintenance personnel, those responsible for toll plaza design and operation, and others concerned with the operation, safety and design of the roadway environment. Information is presented on the various applications of rumble strips on the traveled way and on highway shoulders. This synthesis describes the state of the practice with respect to placement, operational and safety effects, design, installation, and cost and service life of rumble strips. This report of the Transportation Research Board also discusses the effectiveness of rumble strips in preventing or reducing accidents. It provides information on the potential adverse effects of rumble strips, such as noise, motorist use of opposing lanes to avoid rumble strips, maintenance problems, and concerns of special users such as senior citizens, bikers, and truckers. The need for signing and public information support are also discussed. The synthesis presents several recommendations for future research.
