I Audible Traffic Signals HowUsefulAre

چکیده
A rchitects, engineers, and urban planners who work on transportation-related issues are quite familiar with regulations concerning accessibility for handicapped citizens. Concurrent with the development of those regulations has been the refinement of instruction for handicapped citizens on techniques for safe and efficient travel. For blind persons, those techniques are taught by orientation and mobility (O&M) specialists. One of the most important training sequences developed by these specialists is for safe street crossings; it includes the following steps:

Audible pedestrian traffic signals: Part 1. Prevalence and impact.
A collaborative project between the San Diego Association of Governments and San Diego State University (5) evaluated the effectiveness of audible pedestrian traffic signals in aiding visually disabled and elderly persons to walk in their community with greater safety. Three aspects of audible pedestrian traffic signals were investigated: 1) the patterns of use and the impact of these signals o...
متن کاملAudible pedestrian traffic signals: Part 3. Detectability.
This project (10) evaluated audible pedestrian traffic signals (APTS) from three perspectives: 1) the patterns of use and the impact of these signals on pedestrian travel; 2) the physical characteristics of the sound emitted by the Nagoya/Traconex APTS; and, 3) the detectability of the sounds emitted by this brand of APTS. This paper, the last of three companion articles (13,14), describes the ...
متن کاملAudible pedestrian traffic signals: Part 2. Analysis of sounds emitted.
This project evaluated audible pedestrian traffic signals from three perspectives: 1) the patterns of use and the impact of these signals on pedestrian travel; 2) the physical characteristics of the sound emitted by these devices; and, 3) the detection of their emitted sounds in the presence of various traffic noise levels. This paper, the second of three companion articles (2, 3), examines the...
متن کاملThe influence of location of the privileged vehicle siren on the vehicle traffic safety
Audible emergency signals generated by sirens of privileged vehicles should be audible and recognisable by all participants of the traffic. Currently in Poland, A-weighted sound pressure levels of audible emergency signals generated by sirens of privileged vehicles range between 104 and 108 dB. In turn, the A-weighted sound pressure levels measured inside the privileged vehicles may exceed the ...
متن کاملDirectional guidance from audible pedestrian signals for street crossing.
Typical audible pedestrian signals indicate when the pedestrian walk interval is in effect but provide little, or even misleading information for directional alignment. In three experiments, blind and blindfolded sighted adults crossed a simulated crossing with recorded traffic noise to approximate street sounds. This was done to investigate how characteristics of signal presentation affected u...
