  3. Introduction

  4. Existing Conditions

  5. Safety Concerns

  6. Recommendations • Stripe Crosswalk • Speed Limit Signs • Stripe End of Bike Lane • Stripe Restricted Exit Lane on 6th Ave • Rumble Strips on Freeway Off-ramp • Pedestrian Warning & Crosswalk Lights • Update Guide Signs on I-5 & I-405 • Outreach to Businesses on Travel Directions • Other Possible Improvements

  7. Stripe Crosswalk Crosswalk should have been striped after construction. Did the contractor miss it?

  8. Speed Limit Signs There are no signs in this area indicating to drivers that they are entering the downtown core with a 20 mph speed limit. • Add speed limit signs to: • Freeway off-ramp • 6th Avenue before Jackson Street

  9. Stripe End of Bike Lane Stripe an exit flange at the end of the bike lane on 6th Street. Makes it apparent to drivers that cyclists will merge with car traffic.

  10. Stripe Restricted Exit Lane on 6th Ave 30% of off-ramp traffic turns left on College St. Drivers are attention is focused to their left merge rather than pedestrians in the crosswalk on their right. Striping prohibits drivers from dangerous weave maneuver, changing lanes twice in less than 200 feet.

  11. Stripe Restricted Exit Lane on 6th Ave Prohibited Permitted Permitted Permitted

  12. Rumble Strips on Freeway Off-ramp • Need a way to grab the driver’s attention. • Boulder, CO: increased crosswalk compliance by 25%

  13. Pedestrian Warning & Crosswalk Lights Add pushbutton activated in-pavement flashing lights at the crosswalk and on the pedestrian warning signs. Drivers in the left lane or on Jackson Street may not see pedestrians but will see flashing crosswalk lights. • Downside – Pedestrians may perceive security from lights and step in front of cars.

  14. Update Guide Signs on I-5 & I-405 Route traffic headed to Barbur Blvd and OHSU to 4th Avenue instead of 6th. Will reduce exposure at this mid-block crossing. 4th Avenue provides significantly more distance for turning. • Update the guidesigns on I-5/I-405 so that 4th Street shows “Barbur Blvd/OHSU”

  15. Outreach to Businesses Target high traffic generating businesses Advise businesses of safest routes. Google Maps, Mapquest, etc. are not yet updated to reflect changes in traffic patterns on the new mall.

  16. Other Possible Improvements • Add another parking kiosk for PSU parking structure on the West entrance to reduce queuing on 6th Street. • Upgrade Hall/Broadway, Harrison/Broadway signals to accommodate increased volume of left turning vehicles. Possibly split pedestrian and left turn phases.
