About 200 users

Usage--Pedestrians

Screen line conducted 9/13/11 just East of Glenway

Traffic count machines can’t count people…

…they must be observed and recorded manually..

Staffed screen line studies find about 20 percent of path users are walkers

(peak hour study during good weather)

Why Light?

Improve path usefulness

Provide improved visibility along the path

Improve visibility of walkers, as peds are not required to provide a light

Why Light?

Why don’t bicyclists light the path?

SS 347.489 Law requires bicycles have a white, front light that is visible

500 ft away. Plus a red rear reflector visible from all distances from

50 to 500 feet

The law does not require bicyclist’s lights to illuminate the road. The light

Is intended to increase the cyclists visibility to motorists.

Propose

Lighting the path

---using 53w LED fixtures, full-cut off fixture

Fixture

Propose

Lighting the path

---using 20 ft black pole

• Standard street light pole is 30 ft high

• Use of standard 20’ pole allows for efficiencies in purchasing, storage

and replacement

• Shorter poles/bollards increase cost—need more of them to light an area,

need more light fixtures, need more energy, need more maintenance

--increases cost

Pole and FixtureCouncil Crest

Propose

53 Watt LED, special Type 2 w/backlight control

Benefits of LEDs

• Higher color rendering, increased illuminance uniformity

• More efficient, use less energy

• Longer lifespan

• Less maintenance/relamping

• Produce directional light

• Doesn’t produce ultraviolet light which attracts insects
