TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 295: Statistical Methods in Highway Safety Analysis focus on the type of safety analysis required to support traditional engineering functions, such as the identification of hazardous locations and the development and evaluation of countermeasures. Analyses related specifically to driver and vehicle safety are not covered, but some statistical methods used in these areas are of relevance and are summarized where appropriate.

"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.

Safety Analysis of Off-highway Vehicles Use Within Public Rights-of-way in Alaska

Many Alaskans own and operate off-highway vehicles (OHVs) for recreational purposes or for use as primary and secondary modes of transportation. However, the reported crash rate shows that 80 on-road crashes, resulting in five fatalities, occur each year statewide. As a result, the use of OHVs has been identified as a safety concern in the Alaska State Highway Safety Improvement Plan. Minimal research dedicated to understanding OHV use in Alaska exists which limits the potential for improvements that address safety concerns in an equitable fashion. The research presented here contributes to better understanding of on-road OHV use through observational and retrospective analysis. Field-based observations were conducted within highway rights-of-way in 14 strategic locations across Alaska to quantify OHV use and the risk-taking behaviors of riding without helmets, passengers riding without a designated seat, and riding unlawfully on the road. Additional risk factors from the field observations and Alaska Department of Motor Vehicles (DMV) crash data for the period from 2000 through 2016 were identified using the Chi-Square test for independence. Spatial analysis of the Alaska DMV crash data for the period from 2009 through 2016 tested for complete spatial randomness of crashes and identified clusters of crashes by frequency and severity using neighborhood point density statistics. Frequent OHV use was observed with daily traffic volumes exceeding 40 vehicles per day in three field study locations. Several risk-tolerant behaviors were observed including users riding without helmets and vehicles carrying passengers without a designated seat an average of 70 and 20 percent of the time, respectively. Additionally, over half the OHV users were observed to be riding unlawfully using the road. Risk-tolerant behaviors were most frequently observed in communities where on-road use is legal and happened to be coincident with the highest on-road use rates. Overrepresented risk factors for high crash severity incidents included riding at night, in summer, on unpaved roads, on local roads or collectors, in rural areas, for single-vehicle crashes with the occupant not using safety equipment and riding under the influence of alcohol. Crashes were observed to be clustered around towns with the highest frequencies occurring near town centers. The prevalence of risk-tolerant riding behaviors and unlawful on-road riding indicates the need for improvements to existing laws and the education and enforcement thereof. Changes must address the unique needs of users while also considering local jurisdiction such that safety can be improved while also maintain transport equity for residents of rural and isolated communities in Alaska.

"TRB's National Cooperative Highway Research Program (NCHRP) 756: Highway Safety Research Agenda: Infrastructure and Operations develops a proposed agenda of prioritized safety research needs in the area of highway infrastructure and operations. The report provides options to the U.S. transportation community on how to direct research to the areas where it can provide the most benefit. The agenda is based on a prioritization methodology developed by the research team which can be applied on a recurring basis to update the agenda over time. Both the agenda and the methodology documented in this report will assist government officials, private sector employees, and academics with managing highway safety research. In addition to the report, 16 unpublished appendices (Appendices A-O and R) have been made available electronically."--Publisher description.

To reduce traffic fatalities and accidents, the Safe, Accountable, Flexible, Efficient Transportation Equity Act: A Legacy for Users (SAFETEA-LU) nearly doubled funding for the Fed. Hwy. Admin¿s. (FHWA) Hwy. Safety Improvement Program, authorizing $5.1 billion for 2006 through 2009. SAFETEA-LU also added requirements for states to develop strategic hwy. safety plans that cover all aspects of hwy. safety, including infrastructure, behavioral (education and enforcement), and emergency medical services projects; develop crash data analysis systems; and publicly report on the top 5% of hazardous locations on all their public roads. This testimony provides preliminary information on the implementation of HSIP since SAFETEA-LU. Illustrations.

"Observational before-after evaluation of roadway safety treatments effect is a necessary and challenging study area for traffic safety engineers. In decades, empirical Bayesian approach has been widely adopted among researchers in this area. In this approach, the researcher combined before period observation data with a safety performance function estimated from similar groups to estimate the expected number of crashes that would have occurred in the after period without the treatment. Comparing this estimate with the number of crashes observed in the after period, the researcher evaluated the effectiveness of the treatment. This approach accounts for well-known regression-to-the-mean effects. However, as a result of the recent progress in numerical methods made in recent years, more attention has been given on the fully Bayesian approach. The fully Bayesian approach implemented via hierarchical models is believed to have more advantages over the empirical Bayesian approach. The fully Bayesian approach required less data for untreated reference sites, it better accounts for uncertainty in data used, and it provides more detailed causal inferences and more flexibility in selecting crash count distributions. The objective of this study is to compare the differences of the empirical Bayesian procedure and the fully Bayesian procedure for before-after road safety evaluation studies. An illustrative example is included with a step-by-step procedure for both approaches. Throughout three approaches in the example, the estimated safety effects are calculated for MODOT's reference"--Abstract, leaf iii.
