Book Description
ODOT has a goal of reducing total crashes by 10% by 2015. Driver education, licensing, testing, and enforcement strategies are all tools that can be used to help reduce the incidence of accidents, particularly among teenage drivers, who are involved in accidents well out of proportion to their numbers in the overall driver population. In order to determine which strategies are likely to provide the best results, ODOT needs to have some quantitative estimate of the effectiveness of each strategy in terms of the amount of reduction it provides, in other words a crash reduction factor (CRF). A comprehensive literature and web search was conducted to determine driver education, licensing and enforcement practices, and CRF values used by other states and countries. An electronic survey of all states was conducted to get information about driver education, licensing programs, testing and enforcement measures, the state of the art in traffic safety practices, and CRFs. The relatively few CRFs obtained for driver education, licensing programs, and traffic enforcement measures were compared to those obtained for traffic engineering measures. Based on the analysis of all the information obtained only a limited number of quantitative CRFs exist for any of the driver education, licensing and enforcement measures in any of the states in the US. Published studies where the effects on reducing crashes for new measures with sound statistical evaluations using proper control groups appear to be almost non-existent in the US. CRFs for driver education, licensing programs, and enforcement measures based on the estimates by traffic safety experts were found for Switzerland in the VESIPO report and the cost/benefit ratios for some selected Swiss measures were found. It has to be noted that even the Swiss CRFs are based on partial estimates and have not been truly validated with before and after studies using actual data except for one blood alcohol content measure ("Reduction of BAC limit from 0.08% to 0.05%" with extensive advertising and strict enforcement). Since some of the CRFs found were from countries outside the US, such as Switzerland and Canada, and since the road transportation system of the US is fairly similar to Western Europe the strategies used for crash reduction will usually be applicable to Ohio. The range for the CRFs reported in the literature for driver education, driver licensing, testing and enforcement are summarized in the conclusion section of the report. The ranges for CRFs for driver education, licensing programs, and enforcement measures are less than 1% to 32%, 0%-17% and 2%-51% respectively. A prioritized implementation plan based on the highest CRFs reported has been proposed for driver education, licensing and enforcement.

Book Description
From a public health perspective, motor vehicle crashes are among the most serious problems facing teenagers. Even after more than six months of being licensed to drive alone, teens are two to three times more likely to be in a fatal crash than are the more experienced drivers. Crash rates are significantly higher for male drivers, and young people in the United States are at greater risk of dying or being injured in an automobile than their peers around the world. In fact, in 2003 motor vehicle crashes was the leading cause of death for youth ages 16-20 in the United States. Understanding how and why teen motor vehicle crashes happen is key to developing countermeasures to reduce their number. Applying this understanding to the development of prevention strategies holds significant promise for improving safety but many of these efforts are thwarted by a lack of evidence as to which prevention strategies are most effective. Preventing Teen Motor Crashes presents data from a multidisciplinary group that shared information on emerging technology for studying, monitoring, and controlling driving behavior. The book provides an overview of the factual information that was presented, as well as the insights that emerged about the role researchers can play in reducing and preventing teen motor crashes.

Book Description
Research on the therapeutic efficacy of cannabinoids has demonstrated that cannabidiol (CBD), either alone or in 1:1 mixtures with delta-9-tetrahydrocannabinol (THC), can effectively treat animals in experimental models of neuroinflammatory, demyelinative, neurodegenerative, neuropsychiatric, and neoplastic diseases. Short-term, small-scale, human cohorts, observational studies, randomized, non-randomized, placebo-controlled, and uncontrolled clinical trials have provided low-certainty and moderate-certainty evidence that medical marijuana can reduce spasticity, neuropathic pain, neuroinflammation, anxiety, sleep disturbance, urinary bladder dysfunction, frequency and duration of seizure, tumor size, and metastasis as well as promote overall cancer survival. Medical Cannabis and the Effects of Cannabinoids on Fighting Cancer, Multiple Sclerosis, Epilepsy, Parkinson's, and Other Neurodegenerative Diseases presents the findings from clinical and basic medical scientists who are investigating the cellular and molecular mechanisms of cannabinoid-mediated inhibition of innate and adaptive immune responses, mobilization of myeloid-derived immunosuppressive cells, enhancement of neuroprotection, facilitation of oligodendrocyte survival, promotion of CNS progenitor cell differentiation to support regeneration and remyelination, arrest of tumor cell proliferation, decrease in tumor cell adhesion, disruption of tumor angiogenesis, inhibition of endothelial cells, and prevention of cancer metastasis by inhibition of cell migration. The chapters further discuss pharmacologic challenges and precisely how the delicate balance between the opposing effects of various types of cannabinoid receptors can be controlled by manipulating specific membrane channels and signaling pathways to achieve favorable long-term clinicopathologic outcomes in oncology and neurology. Covering topics such as neurodegenerative diseases, spectroscopic applications, and ethical issues, this premier reference source is an essential resource for medical professionals, pharmacists, hospital administrators, government officials, students and faculty of higher education, librarians, researchers, and academicians.

Book Description
"The Highway Safety Manual (HSM) is a resource that provides safety knowledge and tools in a useful form to facilitate improved decision making based on safety performance. The focus of the HSM is to provide quantitative information for decision making. The HSM assembles currently available information and methodologies on measuring, estimating and evaluating roadways in terms of crash frequency (number of crashes per year) and crash severity (level of injuries due to crashes). The HSM presents tools and methodologies for consideration of 'safety' across the range of highway activities: planning, programming, project development, construction, operations, and maintenance. The purpose of this is to convey present knowledge regarding highway safety information for use by a broad array of transportation professionals"--p. xxiii, vol. 1.

Book Description
The primary objective of this research was to systematically review past studies on rear end crashes, examine strategies for reducing rear end crashes on both freeway and non freeway facilities, and develop a set of rear end crash reduction strategies for use in Ohio, which will be appropriate for various traffic engineering solutions, operations and ITS improvements. Accordingly, this study conducted an extensive review of past literature related to rear end crashes and strategies to reduce them. A determination of specific strategies for a road safety improvement program requires an understanding of probable crash reduction capabilities for various geometric, operational and environmental factors on the roadways. Studies of crash reduction strategies have usually focused on before-and-after comparisons of specific locations or conditions. Based on the data provided by the Ohio Department of Transportation, this study attempted to examine the crash reduction capabilities for signalized intersections, unsignalized intersections, freeways and non-freeways where countermeasures were implemented. An attempt was made to compute crash reduction factors for rear end collisions for these roadway facilities. However, this task could not be performed because of the severe limitations in the ODOT countermeasure and roadway site data. In response to the researchers' request for additional data, ODOT decided not to proceed ahead with this research as it required the dedication of district resources that were not currently available. It was believed that breaking the project into smaller, more manageable pieces, would not yield results that would be statistically significant. There were also several national projects underway which would limit this project's benefits. In view of these circumstances, ODOT decided to terminate the contract for this project and all work stopped.
