Low-Cost Pedestrian Safety Zones: Countermeasure Selection Resource

Contract DTNH2216D00017/TaskOrder 693JJ919F000174This project consists of two reports, this one and Low-Cost Pedestrian Safety Zones: Countermeasure Selection Resource. They were developed for State Highway Safety Offices and transportation professionals seeking to support and implement low-cost, quick countermeasures to address pedestrian safety. The handbook describes the process of developing and using low-cost pedestrian safety zones. The resource report details low-cost countermeasures as part of pedestrian safety zone efforts. Pedestrian safety zones target a specifically identified area using a complex combination of countermeasures, typically education, enforcement, and engineering. When done correctly, significant improvements are made

Exploring the Impact of Select Speed-Reducing Countermeasures on Pedestrian and Bicyclist Safety

DTNH2217D00042/ DTNH2017F00184Speed is a contributor to both crash frequency and crash severity. This project explored efforts to reduce speed and evaluated their effectiveness in improving safety for pedestrians and bicyclists. Phase 1 was a program scan that identified countermeasures in use throughout the United States. Based on the scan, the team evaluated automated speed enforcement and road conversions in five municipalities to explore their impact on motor vehicle related pedestrian and bicyclist crashes. Phase evaluated safety benefits of a select group of temporary road conversions implemented in response to the COVID-19 pandemic

High-tension Cable Median Barrier Safety Effectiveness Evaluation

(c) 1030652The objective of this study was to evaluate the change in crash frequency or severity of varying lateral offset distances of high-tension cable median barriers in Minnesota. Crash and traffic data from 2016 to present were conjoined with roadway cross-sectional data and high-tension cable barrier locations to perform cross-sectional analyses for interstate segments equal to or greater than 0.05-miles long. Negative binomial regression models were estimated and used to develop crash modification factors (CMFs) for the following crash types: total crashes, target crashes, and barrier crashes. In addition to evaluating the impact of lateral offset, a na\uefve before-after evaluation was completed to quantify the impact of installing high-tension cable barrier

Accident Research Manual

DOT-FH-11-9424Included in this manual is a compilation of sound research techniques that can be used by the engineer/analyst to carry out research related to highway accidents. Because highway engineering administrators must daily decide how best to spend limited numbers of safety dollars, they need to have results from properly conducted and clearly presented accident research for inputs in this decision-making process. This manual was prepared to meet the continuing need for upgraded research, both in the area of analysis of relationships between accidents and other variables and in the area of countermeasure evaluation. The manual is designed for use by the engineer/analyst who has some background in statistical analysis. The manual contains material related to 1) the rationale and the need for improving the level of existing research, 2) the underlying issues that researchers must be familiar with, 3) the components and methodologies used in the two basic types of accident research--research aimed at evaluating countermeasures and research aimed at identifying and examining underlying relationships between accidents and other highway factors, 4) the preparation and distribution of research results, and 5) summary guidelines for the engineer/analyst to use in his research. The manual has been developed for use in classroom training, as a reference text, and/or in a self-study program. Review questions, self-study pre- and post-tests, and references to related texts and articles are included
