Book excerpt: "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.

This book was released on 2019 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Highway Safety Improvement Program (HSIP) aims to achieve a reduction in the number and severity of fatalities and serious injury crashes on all public roads by implementing highway safety improvement projects. Transportation agencies continuously try to find ways to improve their HSIP. Over the last few years, particular emphasis has been placed on employing advanced safety predictive methods and tools. In 2016, the Texas Department of Transportation (TxDOT) funded research project 0-6912 that developed a) a network screening process for roadway segments, b) preliminary crash analysis and visualization (CAVS) products, and c) a project prioritization tool. TxDOT implementation project 5-6912-01 developed a network screening tool that incorporates the 0-6912 network screening process, and improved and implemented the CAVS process and products to support the diagnosis and countermeasure selection processes at TxDOT. The network screening tool developed in this project automatically scans all on-system mainlane roadway segments in Texas using a dynamic sliding window method and calculates seven safety performance measures for each scanned segment. The performance measures can be used to rank and determine sites with the highest crash risk for further examination. The CAVS products display crash data and locations where certain types of safety countermeasures can be implemented. Among various improvements, the main benefits realized from the implementation of the CAVS products include an increase in the number of candidate projects identified by TxDOT districts between 31 percent to 57 percent and a reduction in the time and effort required to select projects by 20-50 percent.

This book was released on 2014 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compared to microscopic safety studies, macroscopic-focused research is more efficient at integrating zonal-level features into crash prediction models and identifying hot zones. However, macroscopic screening has accuracy limitations. Thus, this study developed a new integrated screening approach to overcome the above-mentioned shortcomings of current screening techniques and to achieve a balance between efforts towards accuracy and efficiency. For conducting macro level safety analyses, the research team faced several challenges. First, using current Traffic Analysis Zones (TAZs) as basic geographic units caused a high percentage of boundary crashes. The research team used regionalization to develop a new study unit: Traffic Safety Analysis Zones (TSAZs) systems. Approximately 10% of boundary crashes have been integrated in new zones after the regionalization but more than 60% of crashes still occur on the boundary of TSAZs. Hence, a nested structure was proposed to estimate safety performance models separately for boundary and interior crashes. This nested structure allows different contributing factors for different crash types, so this model can provide more accurate and predictable results than a single model. In addition, a Bayesian Poisson Lognormal Spatial Error Model (BPLSEM) was adopted for the Safety Performance Function (SPF) analysis. The BPLSEM contains a spatial error term that control for the spatial autocorrelation of crash data. As for the micro level analysis, the research team developed SPFs based on the major function classes of roads in the study area. The research team still used the Full Bayesian Poisson Lognormal models to predict crash frequency but tried four different variable combinations to identify the best model. After identifying hot spot areas at the macro- and microscopic levels, the research team integrated these macroscopic and microscopic screening results. However, this integration task was challenging because of the necessity to (1) combine various SPFs from different scales, areas, and roadway types; (2) determine an appropriate weight for each group; and (3) choose a measurement for the final results. In order to solve the above mentioned problems, this study then developed a new criterion to identify whether a zone has safety issues at the macro- and/or microscopic levels. All TSAZs were classified into twelve categories that included two scale groups (macro or micro) and four safety levels (hot, normal, cold, or no data). Then, the research team defined weights for different scales and roadway types. At the macroscopic level, TSAZs were ranked by their zonal Potential for Safety Improvements (PSIs); at the microscopic level, the calculation of average PSI was more complicated because each TSAZ had several intersections and segments. Both the intersection and segment PSI ranks were averaged. The PSI is used in the Highway Safety Manual (HSM) for network screening but it is the first time that it is used for zonal screening. TSAZs with top 10% PSIs were categorized as “Hot” zones. Finally, the percentile ranks of the PSIs were used in the integration (instead of the original PSIs) because the units of PSI intersections and PSI segments were different. In summary, this study presents an integrated screening method that can be used to overcome the shortcomings of macro- and micro-level approaches. In particular, the results provide a comprehensive perspective on appropriate safety treatments by balancing the accuracy and efficiency of screening. Also, it is recommended that different strategies for each hot zone classification be developed because each category has distinctive traffic safety risks at each of the different levels.

Book Synopsis Measuring Road Safety with Surrogate Events by : Andrew Tarko
Download or read book Measuring Road Safety with Surrogate Events written by Andrew Tarko and published by Elsevier. This book was released on 2019-11-07 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measuring Road Safety Using Surrogate Events provides researchers and practitioners with the tools they need to quickly and effectively measure traffic safety. As 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. This book advances the idea of using these near-crash techniques to deliver quicker and more adequate measurements of safety. It 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. Readers will find 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 updates/ideas from disparate places into a single resource Establishes a consistent use of key terms, definitions and concepts to help codify this emerging field Contains numerous application-oriented case studies throughout Includes learning aids, such as chapter objectives, a glossary, and links to data used in examples
