Accessible Pedestrian Signals: A Guide to Best Practice 203 Chapter 10: International Practice SUMMARY Th e information in this chapter is based primarily on visits made by Janet Barlow and Billie Louise Bentzen during 2001 to four countries whose use of APS has been long term, extensive, systematic, and positively accepted by blind pedestrians and traffi c engineers. Many other countries have a long history of using Accessible Pedestrian Signals.

204 Chapter 10: International Practice Japan FUNCTIONING OF PEDESTRIAN SIGNALS Pedestrian Signal • A "red man, green man" signal is used • Pedestrian signal timing WALK or "green man" timing is fi gured based on walking time of 1 meter per second and is calculated to the center line of the intersection. Flashing DONT WALK timing was reported to be based on a walking speed of 1 meter per second, however this timing seemed to average about 3 seconds regardless of the width of streets.

206 Chapter 10: International Practice • Very few APS had locator tones at the pushbutton. • APS may have a sound for the pedestrian clearance interval: • Yokohama used sound like that of an emergency vehicle • Fairly common in Tokyo to center the APS speaker over the crosswalk on mast arm extending from the pole • APS sound is usually turned off at 8:00 pm because residents nearby are bothered by noise.

208 Chapter 10: International Practice Australia FUNCTIONING OF PEDESTRIAN SIGNALS Pedestrian signals • Red and green man signals with the red man fl ashing during fl ashing DONT WALK interval • All pedestrian pushbuttons were located in very standardized locations, on the side of the crosswalk away from the parallel street, aligned with the crosswalk line, about 0.5 to 1.0 m from the curb line. Most fi xed timed intersections in downtown Sydney had pushbuttons with audible and vibrotactile features.

210 Chapter 10: International Practice • Placement has been standardized at line of the crosswalk away from the center of the intersection. Orientation of face of the APS varied; see photo 4-9.

Accessible Pedestrian Signals: A Guide to Best Practice 211 Sweden FUNCTIONING OF PEDESTRIAN SIGNALS Pedestrian Signals • Sweden uses a "red man, green man" symbol signal. • Use of a fl ashing or clearance interval seems to be a local decision.

212 Chapter 10: International Practice APS FUNCTIONING Th ere is no Swedish standard for APS, but most APS have a ticking sound that repeats at 60 pulses per minute for the locator tone and 600 per minute for the WALK interval. The APS is typically placed on a signal pole or stub pole near the edge of the crosswalk furthest from the intersection, about 0.5 meters from the curb.

Accessible Pedestrian Signals: A Guide to Best Practice 213 COMMENTS Although there were a number of APSs at each intersection, it was possible to locate the devices, and use the WALK indication of the device to cross effi ciently. Because of the precise location of each APS, the information provided was unambiguous as to which crosswalk had the WALK interval.

214 Chapter 10: International Practice Denmark FUNCTIONING OF PEDESTRIAN SIGNALS Pedestrian Signals Red man, green man symbol Pedestrian Signal Timing Length of the WALK interval varies by time of day. WALK interval usually calculated using a walking speed formula of 1.3 meters per second, but up to 1.5 meters per second can be used.

Accessible Pedestrian Signals: A Guide to Best Practice 215 APS FUNCTIONING Most installations have audible signals coming from devices at pushbutton height, whether they have pushbuttons or the signals are fi xed timed; overhead beaconing speaker devices are currently installed in combination with pushbutton locator tones at a few trial locations. Signals must conform to a national standard.

From page 216... ...
216 Chapter 10: International Practice Other • Where there is a pushbutton, it is usually located on the backside of the APS, toward the pole, with suffi cient space for fi ngers to reach between the APS and the pole. • In general there is no need to push a button, as most intersections have pre-timed pedestrian phases.
