Available in PDF, EPUB and Kindle. Book excerpt: "Each year, national crash studies have estimated that while overall traffic fatalities are decreasing, the percentages of those fatalities among pedestrians and cyclists are increasing. NCHRP Research Report 1064: Pedestrian and Bicycle Safety Performance Functions, from TRB's National Cooperative Highway Research Program, presents state departments of transportation and other transportation professionals with an update of pedestrian and bicycle safety performance functions (SPFs). Supplemental to the report are three spreadsheet tools that address SPFs on rural multilane roads, rural two-lane roads, and urban/suburban arterials." -- publisher's website

This book was released on 2014 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigates the factors which affect the safety of non-motorized transportation within the influence area of intersections to enhance development of safety performance functions. The scope of this study is limited to the four Michigan cities of Ann Arbor, East Lansing, Flint and Grand Rapids. Due to the current lack of research regarding the appropriate size of the influence area, this study investigates the distance of crashes relative to the center of 148 intersections to identify the most probable area of influence for different crash types. For motorized and non-motorized crashes, 240 ft. and 137 ft. are proposed, respectively. The proposed area of influence is adopted for developing the SPFs. Crash data from 2008 to 2012 and geometric and exposure characteristics of the intersections are investigated to develop the SPFs. Results of the pedestrian SPF reveal that increased exposure, more left turn lanes, presence of on-street parking, and bus stops at the intersections increase pedestrian crash frequency, while presence of speed signs decrease the number of pedestrian crashes. Results of the bike SPF demonstrate that exposure, presence of bicycle lanes, presence of bus stops and the number of left turn lanes at intersections are positively associated with bicycle crashes. A structural equation model is developed to decipher complex interrelationships among the variables affecting bike crash frequency. Results show that although the presence of bicycle lanes is significant in increasing bicycle crash frequency, bike lanes are correlated with bicycle volume, thus bicycle lanes do not endanger bicycle safety.

This book was released on 2004-12-30 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall goal of the Federal Highway Administration's (FHWA) Pedestrian and Bicycle Safety Research Program is to increase pedestrian and bicycle safety and mobility. The following document describes the level of involvement of Hispanics in pedestrian and bicycle crashes. Possible approaches for local pedestrian and bicycle safety programs targeting Hispanics are presented. The results of this research will be useful to transportation researchers, engineers, planners and safety professionals involved in improving pedestrian and bicyclist safety and mobility.
Download or read book Guidance to Improve Pedestrian and Bicyclist Safety at Intersections written by Rebecca Lauren Sanders and published by . This book was released on 2020 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intersections are challenging locations for all road users, but they can be especially difficult for people walking and biking. Between 2014 and 2016, 27 percent of pedestrians and 38 percent of bicyclists killed in crashes were struck at intersections. The TRB National Cooperative Highway Research Program's NCHRP Research Report 926: Guidance to Improve Pedestrian and Bicyclist Safety at Intersections provides a succinct process for selecting intersection designs and operational treatments that provide safety benefits for pedestrians and bicyclists, and the most appropriate situation for their application. In 2016 and 2017, pedestrians and bicyclists made up 18 percent of all fatalities on U.S. streets, despite representing less than 4 percent of all trips. This continues an upward trend in these modes' share of roadway fatalities since 2007.

Download or read book Bicycle Safety Analysis written by Haizhong Wang and published by . This book was released on 2016 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Around 700 bicycle fatalities happen every year, and the number has steadily increased since 2009. At the same time Seattle, Wash., and Portland, Ore., are promoting cycling as a healthy transportation mode, so bicycle safety has become a more urgent concern for the Pacific Northwest area. The Highway Safety Manual provides an evidence-based approach – safety performance function (SPFs) to evaluate safety for common traffic, but not, however, for bicycles. Therefore, a data-driven and evidence-based bicycle safety evaluation method is needed specifically for the Pacific Northwest region. Based on the first bicycle SPFs created by Krista Nordback in 2013, we used STRAVA bicycle count data (a type of crowdsourced bicycle travel data), other traffic count data, and bicycle crash data to establish Pacific Northwest SPFs in terms of bike count and crash frequency for road intersections. The SPFs demonstrated the relationship between crash frequency and traffic and bike volumes. The intersections with higher traffic volumes had higher bicycle crash frequencies. In addition, this project improved the usability of a GIS tool that had been created during a previous PacTrans project to estimate bicycle exposure. States DOTs and other agencies can use the SPFs to screen and identify previous bicycle black spots in the Pacific Northwest region in order to optimize safety investments.

Download or read book Pedestrian and Cyclist Safety written by Dora Holland and published by . This book was released on 2016 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Walking and biking are becoming increasingly popular modes of transportation: nearly a million more people reported walking or biking to work in 2013 than in 2005. While total traffic fatalities declined from 2004 through 2013 (the most recent year for which data are available), this was not matched by a similar decline in pedestrian and cyclist fatalities. This book examines trends in pedestrian and cyclist fatalities and injuries from 2004 through 2013 and characteristics of these fatalities and injuries; safety initiatives selected states and cities have implemented and their views on challenges in addressing this issue; and actions taken by the U.S. Department of Transportation (DOT) to help improve safety. Furthermore, this book identifies noteworthy and innovative international designs, treatments, and other practices that have potential to improve bicycle and pedestrian safety and access and increase walking and bicycling in the United States.
Download or read book Development of Performance Measures for Non motorized Dynamics written by and published by . This book was released on 2013 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report recommends performance measures for non-motorized (pedestrian and bicyclists) traffic safety for Michigan cities. Based on the data collected from four Michigan cities, Ann Arbor, East Lansing, Flint, and Grand Rapids, the research team analyzed non-motorized safety at three levels (city level, census tract level, and corridor level). The census tract-level analysis revealed that the number of access points, higher population with lower education, and higher exposure measures tended to increase non-motorized crashes. Through detailed corridor-level analyses, safety performance functions (SPF) for intersections and mid-blocks were developed. The intersection SPFs showed that higher average daily traffic (ADT), more number of bars, less number of lanes on minor approaches were associated with higher pedestrian crashes while intersections with right turn lane and bus stops exhibited relatively high number of bicycle crashes. Midblock SPFs also revealed that ADT, the number of access points, and the number of bus stops were factors leading to more non-motorized crashes. This research also presents results of before-and-after studies for non-motorized improvements and how performance measures are used when determining countermeasures.
