13 Intersection Concern 13

14 Recommendations 14 1.Stripe Crosswalk 2.Speed Limit Signs 3.Stripe End of Bike Lane 4.Stripe Restricted Exit Lane on 6 th Ave 5.Rumble Strips on Freeway Off-ramp 6.Pedestrian Warning & Crosswalk Lights 7.Update Guide Signs on I-5 & I Outreach to Businesses on Travel Directions 9.Other Possible Improvements

15 Stripe Crosswalk 15 Crosswalk should have been striped after construction. Did the contractor miss it?

16 Speed Limit Signs 16 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 6 th Avenue before Jackson Street

17 Stripe End of Bike Lane 17 Stripe an exit flange at the end of the bike lane on 6 th Street. Makes it apparent to drivers that cyclists will merge with car traffic.

18 Stripe Restricted Exit Lane on 6th Ave 18 Striping prohibits drivers from dangerous weave maneuver, changing lanes twice in less than 200 feet. 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.

19 Stripe Restricted Exit Lane on 6th Ave 19 ProhibitedPermitted

20 Rumble Strips on Freeway Off-ramp 20 Need a way to grab the driver’s attention. Boulder, CO: increased crosswalk compliance by 25%

21 Pedestrian Warning & Crosswalk Lights 21 Downside – Pedestrians may perceive security from lights and step in front of cars. 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.

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

23 Outreach to Businesses 23 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.

24 Other Possible Improvements 24 Add another parking kiosk for PSU parking structure on the West entrance to reduce queuing on 6 th Street. Upgrade Hall/Broadway, Harrison/Broadway signals to accommodate increased volume of left turning vehicles. Possibly split pedestrian and left turn phases.
