Book Synopsis Guidance for the Design and Application of Shoulder and Centerline Rumble Strips by : Darren J. Torbic
Download or read book Guidance for the Design and Application of Shoulder and Centerline Rumble Strips written by Darren J. Torbic and published by Transportation Research Board. This book was released on 2009 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Practice of Rumble Strips and Rumble Stripes by : Omar Smadi
Download or read book Practice of Rumble Strips and Rumble Stripes written by Omar Smadi and published by . This book was released on 2016 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis documents current practices used by states installing rumble strips and explores variations in practice in terms of design, criteria, and locations for installation, maintenance, perceived benefits, communication of benefits, and important issues. Information was acquired through a literature review, survey on current practice, and case examples. The survey also included questions specific to the state of practice for rumble stripes, which is the term used when the pavement marking lines are painted on the rumble strip in an effort to increase visibility during inclement weather conditions. The findings indicate that two-thirds of the state agencies rely on traditional methods to address the noise issue: skipping rumbles in residential areas, adjusting their depth, or not installing rumbles at all. The overwhelming majority of responding states, 83%, have developed policies or guidance to modify their rumble design practices to be sensitive to cyclists. Fewer than half the respondents have developed policies/guidance to address pavement deterioration; several agencies indicated that pavement condition is a factor on whether to install a rumble or not. The survey also showed that very few state DOTs have created public campaigns to explain that the use of rumbles improves safety so that complaints regarding noise, bicycle issues, and other are minimized.

Book Synopsis Evaluation of a Proposal to Set a Goal for the Virginia Strategic Highway Safety Plan of a Forty Percent Reduction in Traffic Fatalities and Injuries by 2010 by : Young-Jun Kweon
Download or read book Evaluation of a Proposal to Set a Goal for the Virginia Strategic Highway Safety Plan of a Forty Percent Reduction in Traffic Fatalities and Injuries by 2010 written by Young-Jun Kweon and published by . This book was released on 2006 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to determine whether a 40% reduction in traffic fatalities and injuries by 2010 is a reasonable goal to include in Virginia's state-level strategic highway safety plan or whether such a goal is overly optimistic. To achieve the study objective, the scope of the study was limited to making the following determinations: 1. Forecast the total number of traffic fatalities and injuries in Virginia in 2010 assuming three scenarios: In Scenario 1, no state-level traffic safety plan or major traffic engineering safety improvements are implemented between now and 2010. In Scenario 2, only four traffic engineering improvements are made between now and 2010. In Scenario 3, a primary seat belt law along with the four engineering improvements from Scenario 2 are implemented. 2. Determine the probability that Virginia can achieve a 40% reduction in fatalities and injuries by 2010 under Scenarios 2 and 3. 3. Determine realistic goals for the reduction of traffic fatalities and injuries in Virginia in 2010. Based on the forecasts under the three scenarios, the 40% reduction goals are overly optimistic. Assuming a normal distribution of the forecasts, the probabilities of achieving 40% reduction goals for fatalities and injuries are very low or low. Under Scenario 2, if the four engineering treatments are implemented at the 50% level, the probabilities that Virginia would achieve 40% reductions in 2010 are 1.2% for fatalities and 0.012% for injuries. Under Scenario 3, assuming that the primary enforcement seat belt law was enacted and the four engineering treatments were implemented at the 50% level, the probabilities are 8.6% for fatalities and 0.05% for injuries. Accounting for a slight increase in fatalities and injuries in 2010 compared to 2004, realistic goals for Virginia are a 10% (maximum of 20%) reduction goal for fatalities and a 5% (maximum of 10%) reduction goal for injuries. These recommended goals assume that Virginia enacts a primary enforcement seat belt law and exercises enforcement efforts accordingly and deploys engineering crash countermeasures comparable to the 20% to 30% level of implementation of the four treatments used in this study, namely, (1) adding an exclusive left-turn lane to intersections, (2) modifying the signal change intervals, (3) installing centerline rumble strips, and (4) installing/upgrading guardrail.
