Table 3: Uncontrolled Crossing Treatments (in conjunction with markings and signs) tnkoad Ughts • Decreases pedestrian crossing distance • Provides higher pedestrian visibility • Reduces vehicle speeds pproaching the island • Reduces conflicts • Increases usable gips. Reduces pedestrian exposure time • inexpensive • Provides higher pe- destrian visibility • Highlights when a pedestrian crossing is being used • inexpensive • Provides higher pedes- rian visibility to drivers assuming the ag is held in a noticeable location • Highlights a crossing both at night and during the day • Highlights a crossing both at night nd during the day • Provides higher driver awareness when a pedestrian is present P004 d pedeii.044jahliiis: • Provides higher driver awareness Signal Bentorig: when a pedestrian is present - • Provides higher driver awareness when a pedestrian is present • Provides higher driver awareness when a pedestrian is present • In- reases yielding percentage • Increas- es usable gaps • Reduces probability of pedestrian risk taking • Can be seen from 360 degrees • May make snow removal more difficult • May be a hazard for motorists *Small islands not recommended on high-speed roadways ( >40 mph) • May require trained staff or kcal law enforcement, especially on high-speed and high -volume roadways • No effect at night • Requires pedestrians to actively use a flag • Can be easily removed/stolen • Shorter crossings are preferred • Requires pedestrian activation • Minimal to no effect on speed * Snowplows can cause mainte- nance issues • No effect when road surface is snow covered • Requires pedestrian activation • Requires pedestrian activation • Not advisable on multilane streets • Not shown to reduce crashes • Requires pedestrian activation • Requires pedestrian activation La etglitaS • Wide, two-lane roads and multilane roads with suffi- cient right-of-way • At school locations • Downtown/urban locations • High pedestrian volume locations • Across low -speed (<45mph) roadways • In conjunction with in -road warning lights • Downtown/ NR urban conditions Variable 34% 29% depending on length NR • Downtown/urban condi- tions • Low -speed school crossings • Two-lane roads • Midblock crossing locations 65% NR NR 86% Variable 74% <$500 28% 66% 57% (two-lane, 35mph) $3,000— Woo $20,000— $40,000 $12,000— $18,000 • Multilane roadways • Mid -block crossing Ioca- active 47% active 49% S75,000— tions • Lower speed road- passive 31% passive 67% $150,000 ways • Supplement existing pedes- trian crossing warning signs • School crossings • Midblock crossing loca- tions • Low- and high-speed roadways NR = No research found on effect to yielding rate 84% 81% $12,000— $18,000
