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
