Parallel On-Street and Off-Street Bicycling Facilities on
              Portland’s Waterfront Park
  Portland’s Waterfront: Harbor Drive (1942 – 1975)


                                                       The 1975 Waterfront Park

                                  Time Line

•1850s   Front Avenue starts to serve the growing city
•1942    Seawall constructed and Harbor Drive opens
•1975    Harbor Drive demolished
•1978    Waterfront Park dedicated
•1996    Front Avenue renamed Naito Parkway
•2003    Portland Parks and Recreation publishes the Waterfront Park Master
         Plan to improve usability
•2007    Improvements to Waterfront Park completed
         Bike lanes added to NW Naito Parkway

•2010    Improvements to increase cyclist safety on Naito Parkway
                                   Focus Areas
Waterfront Park:
   • A 25-ft-wide, mixed-use concrete walkway running between the Central Lawn
    and the Willamette River
    • Access Points:
              • Hawthorne Bridge and Steel Bridge Access Ramp
              • SW Salmon St.
              • SW Pine St.
              • NW Couch St.
              • NW Davis St.
Naito Parkway:
    • Major thoroughfare running the entire length of downtown between the city and
           Waterfront Park providing access to the downtown core.
    •   Capacity of more than 30,000 veh/day
    •   A posted speed limit of 30 MPH.
    •   Two, well-marked, 5-foot bike lanes were installed on the street in May 2007.
    •   Bike lanes run from NW Davis St. to SW Salmon St., through 8 stop lights
    •   A main bicycle route connecting SE Portland and NW Portland to downtown.
                              Hypothesis


• Waterfront Park is not well suited for commuter bike use because of
interference from other users, such as walkers and runners.

• Commuters will desire to travel at higher speeds which will lead to them
choosing Naito Parkway

• Recreational cyclists will primarily use Waterfront Park

• The peak traffic flow on Naito will most likely be between 8:00am-
10:00am and 4:00pm-6:00pm.

• Peak traffic flow in Waterfront Park will be between 11:00am and 1:00pm
with the highest use occurring on weekends.
                                         Methodology

•   Scope
     o   Distinguish between the users of Naito
         Parkway and Waterfront Park
     o   Determine a method of data collection that
         will provide the most useful data
     o   Collect and analyze this data
     o   Compare the results of the two routes

                            Trends in Riders

• Road bicycles were the most common on both routes.

• Casual dress was the most common on both routes.

• Bags were carried most frequently.

• Helmets were worn by majority of riders.

• Age had the greatest percentages in the 30 to 50 year old range.*

• Commuters dominated the bicycle contingent.

• More Male riders on both paths, however in different ratios.

• More north bound riders on Naito, and South bound in park.
           What Type of Rider is Where and When?

What were the bicyclists doing?
· Majority were Commuting
                                      Wor
· Some Sport Riders                   k

· Surprisingly, Leisure riders were
observed on both routes.


Where were the bicyclists going?
• Home and Work
• Bridges into downtown.
• Enjoying the waterfront.
    What Type of Interactions do Bicyclists Have
          When Using Waterfront Park?


•Pedestrians
•Joggers
•Skateboards
•Miscellaneous
                    Proving Our Hypothesis

•“Waterfront Park is Not Well Suited for Cyclist Commuters”

•“Commuters will prefer Naito for ability of Greater Speed and
elimination of weaving through crowds”
   • Opposite is True

   • More Commuters in Waterfront Park

   • More Leisure Riders on Naito Parkway

•How   Safe do the Riders Feel?
   •   Few People Surveyed Generally Feel Safe
                      Proving Our Hypothesis


“Peak Flow Will be from
4:00 – 6:00pm on Naito”

“Peak Flow Will be from
11:00 am in Park”

                          Capacity for Our Time Trial Investigation
What types of transitions are there
   between the two routes?
       Do Improvements Need to Be Made?


Depends:
• What is the Intention of Each Facility?

• Should Commuters be Allowed in the Park?

• Future Plans?

Recommendations:
• Split Path - Venice Beach
• Bike Only Path in Park - Amsterdam
• North Bound on Naito - “Roll Through Red”
• Others?
