Download and read online ebook Measuring Road Safety with Surrogate Events write by Andrew Tarko. This book was released on 2019-11-15. Measuring Road Safety with Surrogate Events available in PDF, EPUB and Kindle. Measuring Road Safety Using Surrogate Events provides researchers and practitioners with the tools they need to quickly and effectively measure traffic safety. Traditional crash-based safety analyses are being undermined by today's growing use of intelligent vehicular and road safety technologies. Crash surrogates--or near misses--can be more effectively used to measure the future risk of crashes. Measuring Road Safety Using Surrogate Events advances the idea of using these near-crash techniques to deliver quicker and more adequate measurements of safety. The book explores the relationships between traffic conflicts and crashes using an extrapolation of observed events rather than post-crash data, which is significantly slower to obtain. It delivers sound estimation methods based on rigorous scientific principles, offering compelling new tools to better equip researchers to understand road safety and its factors. Consolidates the latest thinking from disparate places into one resource Establishes a consistent use of key terms, definitions, and concepts to help codify this emerging field Numerous application-oriented case studies throughout Learning aids include chapter objectives, glossary, and links to data used in examples

Download and read online ebook Use of Harsh-braking Data from Connected Vehicles as a Surrogate Safety Measure write by Nathaniel Patrick Edelmann. This book was released on 2022. Use of Harsh-braking Data from Connected Vehicles as a Surrogate Safety Measure available in PDF, EPUB and Kindle. "Traffic safety may be analyzed with the use of surrogate safety measures, measures of safety that do not incorporate collision data but rather rely on the concept of traffic conflicts. Use of these measures provides several benefits over use of more traditional analysis methods with historical crash data. Surrogate measures eliminate the need to wait for crashes to occur to conduct a safety analysis. The amount of time required for enough crash data to accumulate can be significant, delaying safety analyses. Similarly, these measures allow for safety analysis to be conducted prior to crashes occurring, potentially calling attention to hazardous areas which may be altered to prevent crashes. In addition to these benefits, traffic conflicts occur much more frequently than collisions, generating many more data points which in turn make statistical methods of analysis more effective. Evaluating surrogate safety measures for a particular transportation network is most effectively done with the use of traffic microsimulation or with connected vehicle data. Traffic microsimulation (such as the use of PTV VISSIM) will generate kinematic data that may then be used for computation of surrogate safety measures. A significant amount of research has been done on this topic, resulting in the establishment of algorithms for calculation of several different surrogate measures and validation of these measures. Kinematic data from connected vehicles has also been used for the calculation of surrogate safety measures. One data point collected by connected vehicles is harsh braking events which could serve as a surrogate safety measure. Because drivers usually brake more gently if given the opportunity to do so, harsh braking events indicate that a traffic conflict has occurred or is about to occur. Such events take away the driver’s opportunity to brake gently. This research establishes statistical models which relate harsh braking events to crashes on intersections and segments in Salt Lake City, Utah. The findings indicate that harsh braking events have the effect of reducing expected crashes because they represent traffic conflicts which were remedied through the use of harsh braking as an evasive action. The presence of schools and the presence of left turn lanes were also found to be statistically significant crash predictors. In addition to this research work a paper outlining the existing state of safety analysis with surrogate safety measures and evaluating the usefulness and practicality of various existing measures is presented."--Boise State University ScholarWorks.
