Use in all cases. 25 40.3<br />
Low pedestrian activity; intersections that do not contain<br />
the required pedestrian demographics.<br />
Wide streets; if streets are too wide, pedestrians may<br />
not have a clue how long it would take to cross, so the<br />
numbers displayed could be meaningless. In these<br />
cases, education could address this potential issue.<br />
Short crossings/narrow roadways with less than three<br />
lanes to cross.<br />
Smaller, two-phase intersections with one lane per<br />
direction.<br />

Do not use if planning to reduce the pedestrian<br />
clearance phase during preemption.<br />

Where preempt programming may override countdown<br />
operations.<br />
High vehicular speeds. 2 3.2<br />
Where there are no crossing facilities <strong>for</strong> pedestrians 1 1.7<br />
Do not use with signals where the WALK time varies<br />
due to coordination if the countdown begins with the<br />
WALK display (unless the countdown signal technology<br />
has addressed this issue).<br />
Alternatively, tell pedestrians how long they have to wait<br />
rather than scare them into clearing the road.<br />

Where motorists have a clear view of the timer display. 1 1.6<br />
Difficult to use on a main street <strong>for</strong> a side street<br />
crossing.<br />
On main streets; crossing the shorter distance of the<br />
1 1.6<br />
side street. There is the concern that the driver on the<br />
main street may use them to determine the onset of<br />
amber and possibly try to beat the light.<br />
1 1.6<br />
Do not use where the WALK indication is included in the<br />
countdown.<br />
