incorporate such systems, in which the driver first sees a flashing amber signal upon <br />edestrian activation and then a solid red while the pedestrian crosses to the splitter <br />island (there is no green). These types of signals are also used in some U.S. cities at <br />edestrian crossings of arterial street or highways. The pedestrian pushbutton should be <br />identifiable by a locator tone, and an accessible pedestrian signal incorporated to <br />rovide audible and vibrotactile notice of the gap created by the red signal. If properly <br />signed, it need only be used occasionally by those who do not wish to rely solely on visual <br />gap selection. <br />Roundabout intersections with single -lane approach and exit legs are not required to <br />rovide signals. <br />R305.7 Channelized Turn Lanes at Intersections. Where pedestrian crosswalks are <br />provided at multi -lane right or left channelized turn lanes at intersections with pedestrian <br />signal indications, a pedestrian activated signal complying with R306 shall be provided. <br />Advisory R305.7 Channelized Turn Lanes at Intersections. Accessible pedestrian signal <br />devices installed at splitter and 'pork chop' islands must be carefully located and <br />separated so that signal spillover does not give conflicting information about which <br />crossing has the WALK indication displayed. <br />Additional guidance on signal types is provided in Advisory R305.6.2. <br />R306 Accessible Pedestrian Signals (APS) <br />R306.1 General. Pedestrian signals shall comply with R306. <br />R306.2 Pedestrian Signals. Each crosswalk with pedestrian signal indication shall have <br />an accessible pedestrian signal which includes audible and vibrotactile indications of the <br />WALK interval. Where a pedestrian pushbutton is provided, it shall be integrated into <br />the accessible pedestrian signal and shall comply with R306.2. <br />Advisory R306.2 Pedestrian Signals. Signals should generally sound and vibrate <br />throughout the WALK interval. Where signals rest in WALK, audible operation may be <br />limited to a repetition at short intervals rather than continuous sounding for several <br />minutes. <br />R306.2.1 Location. Accessible pedestrian signals shall be located so that the <br />vibrotactile feature can be contacted from the level landing serving a curb ramp, if <br />provided, or from a clear floor or ground space that is in line with the crosswalk <br />line adjacent to the vehicle stop line. <br />R306.2.1.1 Crossings. Accessible pedestrian signal devices shall be 3.0 <br />m (10.0 ft) minimum from other accessible pedestrian signals at a <br />crossing. The control face of the accessible pedestrian signal shall be <br />41 <br />
