Available in PDF, EPUB and Kindle. Book excerpt: The Highway Safety Improvement Program (HSIP) is a core Federal-aid, state-administered program in which each state is required to develop and establish planning, implementation, and evaluation processes. The goal of evaluation activities is to determine if highway safety improvements are achieving the desired results and the investments are worthwhile. The goal of this study is to advance HSIP evaluation processes and practices at the Texas Department of Transportation (TxDOT) and evaluate the safety and cost effectiveness of HSIP projects and countermeasures or work codes (WCs) that have been implemented in Texas over the last few years. This research involved: a) reviewing safety and cost effectiveness evaluation methods, state practices, and tools; b) gathering and compiling TxDOT data and assessing their appropriateness for supporting HSIP evaluations; c) developing safety and cost effectiveness evaluation tools for segments and intersections; and d) evaluating the effectiveness of implemented HSIP projects and countermeasures in Texas. The results show that the evaluated projects have been effective from both a safety and cost perspective in reducing target fatal, suspected serious injury, and non-incapacitating injury (KAB) crashes. The safety effectiveness index of 387 evaluated segment projects (treated as one group) was 0.84, and the corresponding index of 70 intersection projects (treated as one group) was 0.74, indicating an overall reduction in target KAB crashes after the projects were constructed. The benefit/cost ratio of all segment projects was 71.9 and that of all intersection projects (treated as one group) was 145.6.

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.

Download or read book Highway Safety Improvement Program HSIP Evaluation Guide written by Frank Gross and published by . This book was released on 2017 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Highway Safety Improvement Program (HSIP) comprises three components: planning, implementation, and evaluation. This guide focuses on the evaluation component, which provides a critical feedback loop to update processes and inform future decisions. The target audience includes safety program managers, project managers, data analysts, and researchers involved with project, countermeasure, or program evaluations, in particular HSIP evaluations. The purpose of the HSIP Evaluation Guide is to provide direction and resources to agencies that want to begin or enhance HSIP evaluation efforts. Readers will be prepared to track critical project details in support of HSIP evaluation, perform three different levels of evaluation (i.e., project, countermeasure, and program level), and use the results of HSIP evaluations to improve decisions and processes. Readers will also understand the methods, data requirements, and considerations associated with the different levels of evaluation. Examples from various States highlight noteworthy practices and the benefits of evaluation. Employing more consistent and reliable evaluation methods will support safety decision making, positively affect processes intended to reduce crashes, optimize return on investment of safety funding, and increase the effectiveness of projects and programs.

This book was released on 1979 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many hazardous locations exist on our local and street highway systems. Such hazards contribute to the frequency and severity of traffic accidents. The elimination and mitigation of the hazards reduces accident frequency and severity, as measured by the number of fatalities, injuries and property damage resulting from the accidents. The accident potential and the accident severity for the existing situation and for improvements are estimated to determine the number of fatal, injury and property damage only accidents. The reduction in accidents because of the safety improvement are used to measure the safety benefits. These benefits are compared with the costs of the improvements using economic analyses techniques. A decision making framework is developed which employs economic evaluation methods and takes account of budget limitations, to rank safety improvements. This approach leads to the selection of the most cost-effective safety improvement alternatives for highways and streets in local jurisdictions.

This book was released on 1994 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to determine the adequacy with which safety problems on low-volume rural roadways were addressed by the four states of Federal Region VII (Iowa, Kansas, Missouri, and Nebraska), a review was made of the states' safety policies. After reviewing literature dealing with the identification of hazardous locations, evaluation methodologies, and system-wide safety improvements, a survey of the states' safety policies was conducted. An official from each state was questioned about the various aspects and procedures dealing with safety improvements. After analyzing and comparing the remarkably diverse policies, recommendations were made in the form of a model safety program. This program included special modifications that would help remediate hazards on low-volume rural roadways. Especially encouraged is a system-wide approach to improvement which would cover all parts of the highway system, not just urban and high-volume roadways.
