III. DESCRIPTION/BACKGROUND
As a part of the ongoing efforts to address concerns regarding pedestrian visibility at night or early morning in unprotected crosswalks, staff began researching supplemental crosswalk lighting to improve pedestrian visibility during periods of darkness. Staff would like to introduce a pilot project which will bridge the gap between standard streetlights and active devices such as Rectangular Rapid Flash Beacons (RRFB).
The crosswalk locations for the pilot projects are:
• NE 90th St at 161st Ave NE (the crosswalk just west of Coho Café)
• NE 104th St at 172nd Ave NE (near Redmond HS)
• NE 79th St at 169th Ave NE (Anderson Park)
A. Analysis
Process to Date:
Staff researched solutions from eight different lighting manufacturers:
1. Ragni Lighting
2. ERW Lighting
3. iGuzzini Lighting
4. Abel Lighting
5. PSE
6. Intrigue Lighting
7. Sea-Tac Lighting
8. Howard Industries
Howard Industries currently offers the best solution to on-demand supplemental illumination for pedestrian walkways and crosswalks. Their large devices (6’) have been in use on business, educational and hospital campuses.
Following staff’s request, Howard Industries created a smaller model; LightPath. It is a more appropriate size (4’) for use at unprotected crosswalks in Redmond.
