Available in PDF, EPUB and Kindle. Book excerpt: This evaluation determined the change in crash frequency, type or severity associated with longitudinal rectangular rumble strips on rural two-lane undivided and rural four-lane divided Minnesota roadways constructed between 2012 and 2018. Crash Modification Factors (CMFs) were estimated using cross-sectional analysis to compare crash experience of locations with (i.e., centerline only, centerline + shoulder, or shoulder only) and without rectangular rumble strips. The cross-sectional analysis matched sites with and without rumble strips using matched-pair comparisons. Negative Binomial (NB) or Poisson log-linear regression models were used to model the crashes at all treatment and non-treatment sites. There was a total of approximately 1,200 miles of treated (i.e., centerline only, centerline + shoulder, or shoulder only) and untreated sites on rural two-lane roads and approximately 35 miles of treated (i.e., shoulder rumble strips) and untreated sites on rural four-lane divided roads. On rural two-lane undivided roads, the CMF for centerline + shoulder rumble strips was 0.73 for all crashes; shoulder only rumble strips had a CMF of 0.68 for all crashes. For single vehicle run-off-the-road crashes on rural two-lane highways, the CMF for rumble strips on the centerline + shoulder was 0.68; the CMF for shoulder only rumble strips was 0.76. The CMF for head-on, or opposite direction sideswipe crashes on rural two-lane roads with centerline and shoulder rumble strips was 0.64. On rural four-lane divided roads, the CMF for shoulder rumble strips for all crashes was 0.66 and 0.40 for single vehicle run-off-the-road crashes.

Book excerpt: MDOT's rumble strip program for two-lane high speed rural highways was initiated in 2008 and continued through 2010. This program included implementation of centerline rumble strips (CLRS) on nearly 5,400 miles of two-lane high speed roads that MDOT maintains. This program presented an opportunity to perform a comprehensive evaluation of safety performance of rumble strips, especially CLRS. A two-phase evaluation study of the program was launched to estimate the driver behavioral and performance improvement in the presence of CLRS on two-lane high speed highways and also perform a system-wide "Before" and "After" study of target traffic crashes. The driver behavior-related study and collection of the three years' "Before" crash data and analysis was performed in Phase I (OR09084A) and the Phase II study was performed to collect the three years of "After" crash data, a program evaluation study, and benefit-cost analysis. The crash analysis indicated statistically significant reductions in all target crashes including, head-on, sideswipe opposite and run-off-the-road left. The study of crashes and their severity resulted in the reduction in fatal and all categories of injury crashes including a 47% reduction in total target crashes and a 51% reduction in target fatal crashes. An economic analysis of the rumble strip program resulted in a benefit-cost ratio of the program to be in the range of 58:1 to 18:1 based on discount rate assumptions of 2% and 10%, respectively. A road user survey indicated strong agreement among the respondents that CLRS is a beneficial safety improvement program.

Download or read book Sleepiness written by Michael J. Thorpy and published by Cambridge University Press. This book was released on 2011-01-27 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written and edited by leading clinicians and researchers in sleep medicine, this is the first book to focus on the causes, consequences and treatment of disorders of excessive sleepiness. Extensive coverage is provided for all known causes of sleepiness, including sleep deprivation, obstructive sleep apnea syndrome, narcolepsy and other hypersomnias of central origin, shift work, and medical and psychiatric disorders. Since many causes of sleepiness are difficult to differentiate from each other, and treatment modalities can vary greatly from one disorder to another, this book helps the clinician to formulate a differential diagnosis that will ultimately lead to the correct diagnosis. Epidemiology, evaluation of the sleepy patient, diagnostic investigations including neuroimaging, subjective and objective testing, cognitive effects of sleepiness, motor vehicle driving issues, medico-legal aspects of sleepiness, and therapy are also discussed in detail. This is an essential resource for neurologists, psychiatrists and sleep specialists.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
