This book was released on 2005 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: In late 2000, the Northern Virginia District of the Virginia Department of Transportation (VDOT) received a request from a visually impaired citizen to install accessible pedestrian signals (APS) at an intersection in Falls Church. Since there were no national or state guidelines for this type of installation, the district was asked to install APS at an intersection in a pilot effort and to develop appropriate guidelines that VDOT could use statewide for future installations. The Virginia Transportation Research Council was asked to assist in developing the guidelines. Further, a committee composed of representatives from VDOT, the Federal Highway Administration, the Virginia Department for the Blind and Visually Impaired, and the blind and visually impaired community (formal organizations and individual citizen activists) was established to provide overall guidance and advice. A Phase I report documented the initial efforts to develop the guidelines and described the following sections of the guidelines: (1) a procedure for requesting APS, (2) the basic requirements for retrofitting, (3) an intersection evaluation methodology, and (4) a funding process. In addition, the report recommended that the procedures in these four sections be piloted by using them to identify other appropriate intersections at which different types of APS equipment could be installed. This Phase II report describes the results of the pilot with regard to the first four sections of the guidelines and the development of the final two sections of the guidelines: the basic statewide specifications for APS equipment, and the installation procedures. The final guidelines for installing APS at an existing intersection are included in an appendix.

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.
