Book Synopsis Investigation of Driver Speed Choice and Crash Characteristics During Low Visibility by : Katie McCann
Download or read book Investigation of Driver Speed Choice and Crash Characteristics During Low Visibility written by Katie McCann and published by . This book was released on 2016 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Virginia, sections of I-77 and I-64 in mountainous parts of the state have significant recurring fog events. These locations have also been the sites of several chain reaction crashes involving more than 50 vehicles during fog. These crashes were typically caused by drivers traveling too fast for the visibility conditions. To improve safety on the I-77 corridor, the Virginia Department of Transportation constructed a variable speed limit (VSL) system that posts dynamic speed limits based on the visibility condition. As of April 2016, the system was undergoing pre-deployment testing. Before the system was activated, it was important to understand existing driver speed choice behavior during low visibility conditions. It was possible that posting a VSL speed based only on the stopping sight distance (SSD) could create significant speed variance and decrease safety if drivers were driving much faster than conditions would warrant. In this study, crash, speed, and visibility data were examined at several locations on I-64 and I-77 where there were recurring fog events. The crash history for I-77 revealed that crashes during low visibility conditions were more likely to be severe and involve more than two vehicles than crashes during clear conditions. Mean speed analysis found that observed mean speeds exceeded safe speeds for all low visibility conditions and at all sites. In the worst visibility conditions, drivers often exceeded the safe speed by more than 20 mph. Standard deviation analysis found that speed variance did not increase as visibility decreased on I-77, but for several locations on I-64, the standard deviation was different during low visibility when compared to clear conditions. Models were developed to allow a better understanding of the relationship between speed and visibility. The models showed that although motorists reduce their speeds in low visibility, there is still a significant differential between observed speeds and the safe speed calculated using the SSD. The models showed that speeds for I-64 were much less sensitive to changes in visibility compared to I-77. A possible explanation for this difference is the presence of illuminated in-pavement markers on I-64. The improved delineation provided by these markers during foggy conditions may cause drivers to perceive less of a need to reduce speed during limited visibility. It is also possible that mean speeds in low visibility conditions are higher on I-64 because of the regular commuters who may be more comfortable driving during foggy conditions. The observed driver behavior from this study is being used as a basis for the VSL control algorithm that is being implemented in the field. A primary concern of the operators of the VSL system is that it will not be heeded by all motorists and thus will result in increased speed variance in foggy conditions. The developed model was used to create a VSL control algorithm to help bridge the gap between current driver behavior and safe speed. It is recommended that future VSL system deployments reflect existing driver behavior in the initial algorithms as well. After VSL activation, speed and crash data for I-77 should be analyzed to determine the operational and safety effects of the system. If the system on I-77 reduces the frequency and severity of crashes, improves speed limit compliance, and reduces speed variance, a similar system should be developed for I-64 using the current driver behavior models from this study as part of the initial algorithm.

Download or read book Strong Towns written by Charles L. Marohn, Jr. and published by John Wiley & Sons. This book was released on 2019-10-01 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new way forward for sustainable quality of life in cities of all sizes Strong Towns: A Bottom-Up Revolution to Build American Prosperity is a book of forward-thinking ideas that breaks with modern wisdom to present a new vision of urban development in the United States. Presenting the foundational ideas of the Strong Towns movement he co-founded, Charles Marohn explains why cities of all sizes continue to struggle to meet their basic needs, and reveals the new paradigm that can solve this longstanding problem. Inside, you’ll learn why inducing growth and development has been the conventional response to urban financial struggles—and why it just doesn’t work. New development and high-risk investing don’t generate enough wealth to support itself, and cities continue to struggle. Read this book to find out how cities large and small can focus on bottom-up investments to minimize risk and maximize their ability to strengthen the community financially and improve citizens’ quality of life. Develop in-depth knowledge of the underlying logic behind the “traditional” search for never-ending urban growth Learn practical solutions for ameliorating financial struggles through low-risk investment and a grassroots focus Gain insights and tools that can stop the vicious cycle of budget shortfalls and unexpected downturns Become a part of the Strong Towns revolution by shifting the focus away from top-down growth toward rebuilding American prosperity Strong Towns acknowledges that there is a problem with the American approach to growth and shows community leaders a new way forward. The Strong Towns response is a revolution in how we assemble the places we live.

Book Synopsis Evaluating the Impacts of Driver Behavior in the Speed Selection Process and the Related Outcomes by : Cole D. Fitzpatrick
Download or read book Evaluating the Impacts of Driver Behavior in the Speed Selection Process and the Related Outcomes written by Cole D. Fitzpatrick and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the United States, traffic crashes claim the lives of 30,000 people every year and is the leading cause of death for 5-24 year olds. Driver error is the leading factor in over 90 percent of motor vehicle crashes, with the roadway and the vehicle each only accounting for about 2 percent of crashes. In the United States, nearly a third of fatal crashes are due to speeding and therefore, a critical step in improving traffic safety is research aimed to reduce speeding, such as crash data analysis, outreach campaigns, targeted enforcement, and understanding speed selection. In this dissertation, a multi-faceted approach was taken to improve roadway safety by examining the speeding-related crash designation, improving speed limit setting practices, and understanding the causes of speeding. Multiple experiments were conducted under this overarching goal. These experiments included an analysis of speeding-related crashes in Massachusetts, a naturalistic driving study, and a driving simulator study which investigated the causes of speeding. Collectively, the findings from these experiments can expand upon existing speed prediction models, improve crash data influence speed limit setting practices, guide speed management programs such as speed enforcement, and be used in public safety outreach campaigns.

Book Synopsis Posted Speed Limit Setting Procedure and Tool by : Kay Fitzpatrick
Download or read book Posted Speed Limit Setting Procedure and Tool written by Kay Fitzpatrick and published by . This book was released on 2021 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several factors are considered within engineering studies when determining the posted speed limit, including the 85th percentile speed, which is based on the driving behavior of most drivers (85 percent). The 85th percentile speed is believed to represent a safe speed that would minimize crashes. The TRB National Cooperative Highway Research Program's NCHRP Research Report 966: Posted Speed Limit Setting Procedure and Tool: User Guide provides and explains a speed limit setting procedure (SLS-Procedure) that considers factors beyond the 85th percentile speed, including both driver speed choice and safety associated with the roadway. This report also provides instructions for using an automated version of the SLS-Procedure via a spreadsheet-based Speed Limit Setting Tool (SLS-Tool). Two versions of the SLS-Tool are available: N17-76 SLS-Tool (with macros) and N17-76 SLS-Tool (without macros). The "without macros" version is made available for users who are not able to use macro codes on their computers. Please see the User Guide for more detailed information on using both versions of the SLS-Tool. The report is also accompanied by NCHRP Web-Only Document 291: Development of a Posted Speed Limit Setting Procedure and Tool, which documents the research efforts of NCHRP Project 17-76 - Guidance for the Setting of Speed Limits and a Presentation that offers an overview of the project.

Book Synopsis The Fast and The Furious: Drivers, Speed Cameras and Control in a Risk Society by : Helen Wells
Download or read book The Fast and The Furious: Drivers, Speed Cameras and Control in a Risk Society written by Helen Wells and published by CRC Press. This book was released on 2022-03-26 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fast and The Furious: Drivers, Speed Cameras and Control in a Risk Society presents a sociological and criminological perspective critical to understanding the driver's role at the centre of road safety interventions. Such an approach is, it is argued, as crucial to an understanding of attempts to reduce road crashes, deaths and injuries as approaching such questions from an engineering or educational perspective. The book offers an explanation for the continued debate about one road safety intervention - the speed camera - by situating that debate within contemporary literature about the 'risk society' (Beck, 1992) and more broadly understood experiences of risk faced on a daily basis by drivers. Rather than a focus on risk as something that can be objectively assessed, measured and managed separately from the social context in which it is encountered, it suggests that 'risk' is something that permeates this particular debate from every angle. The book achieves its aims by utilising sociological and criminological perspectives to investigate issues such as: - the social context in which it is possible for drivers to reject official scientific expertise about crash causation and camera effectiveness - the self-defined 'respectability' of the population being problematised and its juxtaposition with a 'proper' police focus on 'real criminals' - the reconceptualisation of law-breaking as risk-taking rather than inherently 'wrong' behaviour and its consequences for the enforcement of laws based on risk assessment - the experience of being controlled by technology and of receiving what is essentially 'automated justice'. These and other issues are explored and suggested as illuminating of both the real concerns underpinning this debate and potentially instructive for future attempts to control risky behaviour both within and beyond a road safety context.
