Book excerpt: This comprehensive report on pedestrian safety builds on the current level of knowledge of pedestrian safety countermeasures by identifying the most effective advanced technology and intelligent transportation systems, such as automated pedestrian detection and warning systems (infrastructure-based and vehicle-based), road design, and vehicle structural design improvements, that could potentially mitigate the crash forces on pedestrians in the event of a crash. The report also includes recommendations on how new technological developments could be incorporated into educational and enforcement efforts and how they could be integrated into national design guidelines developed.

Download or read book Automated Pedestrian Detection Count and Analysis System written by Venki Muthukumar and published by . This book was released on 2015 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pedestrian and bicycle count data is necessary for transportation planning, implementing safety countermeasures, and traffic management. This data is critical when evaluating the pedestrian level of service of safety (LOSS) and pedestrian safety performance function (SPF). Also, a performance analysis tool with both vehicle and pedestrian data is required to comprehensively analyze intersection safety. The primary goal of the proposed research is to develop an automated system/framework that detects and counts pedestrians, generates pedestrian flow characteristics, and evaluates pedestrian-vehicle conflicts for a given pedestrian crossing to improve safety. The proposed research will also develop a database system for safety analysis tool to perform network screening and countermeasure selection modules. The database will include typical intersection analysis data plus pedestrian and bicycle counts and conflict data. This document is the first quarterly progress report for this project. This progress report discusses the research tasks, presents the project schedule, gives a brief summary of progress, and presents results of the literature review.

Download or read book Large Field Test of New Stereo Detection System for the Pedestrian Signal Phase for the Visually Impaired written by Bo Ling and published by . This book was released on 2012 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: In March 2010, a large field test study was conducted on a stereo pedestrian detection system in four cities in four States under the Federal Highway Administration's Small Business Innovative Research program. The objective was to prove that the stereo vision would reliably detect pedestrians in real-world environments under all weather conditions (e.g., sunny, cloudy, foggy, rainy, and snowy) and extreme temperatures (e.g., very high temperatures in the southern part of the country and very low temperature in the northern part of the country) and determine that the system effectively actuates pedestrian calls and locator tones on accessible pedestrian signals (APSs). The study was conducted in Tucson, AZ; Somerville, MA; Portland, ME; and Manchester, NH. The stereo pedestrian detection systems were installed to evaluate their performance in complex real-world pedestrian/traffic environments under all weather conditions and extreme temperatures. A total of 17 systems, consisting of one computer and two cameras per crossing, were installed at 9 geographically disparate test sites. These were installed at both midblock crossings and at intersections. When pedestrians were detected at crosswalk ramps, the system automatically actuated both regular and APS pushbuttons to make the service request on behalf of the pedestrians. System performances were evaluated using images saved in external hard disks. Results from the testing showed that the overall positive detection rate for the automated APS actuation zones in all four cities was close to 98 percent, with the average number of false calls per day less than three. This excellent performance was confirmed through the real operations of systems installed at the test sites. Currently, all of the systems are operational 24 h a day, 7 days a week. Comments from the general public, including the blind and visually impaired community, were all positive. This system provides automated actuation of pushbuttons based on the presence of pedestrians. This provides the protection of pedestrian phases, thereby reducing the possibility of collisions between vehicles and pedestrians, preventing unnecessary fatalities, and automatically extending the walk time for seniors and wheelchair pedestrians without slowing down the traffic flow.

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 2011-10-16 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Machine learning builds models of the world using training data from the application domain and prior knowledge about the problem. The models are later applied to future data in order to estimate the current state of the world. An implied assumption is that the future is stochastically similar to the past. The approach fails when the system encounters situations that are not anticipated from the past experience. In contrast, successful natural organisms identify new unanticipated stimuli and situations and frequently generate appropriate responses. The observation described above lead to the initiation of the DIRAC EC project in 2006. In 2010 a workshop was held, aimed to bring together researchers and students from different disciplines in order to present and discuss new approaches for identifying and reacting to unexpected events in information-rich environments. This book includes a summary of the achievements of the DIRAC project in chapter 1, and a collection of the papers presented in this workshop in the remaining parts.
