(An innovative bicycle treatment…)
                                     Foil spokes
 Innovation in transportation is
fueled by the energy of many…
And the wild imagination of a few...

But seriously, folks
Innovative treatments:

• Process (NCUTCD)

• Current NCUTCD
  topics

• Other innovations
           “To be effective,
 a Traffic Control Device should…”

A. Fulfill a need;
B. Command attention;
C. Convey a clear, simple meaning;
D. Command respect from road users; and
E. Give adequate time for proper response.

                 “Dooring” fatality




AASHTO-standard urban bike lane (5’ bike area, 7’ parking)
but only the leftmost 2’ of the 5’ striped area is relatively safe.
Right handlebar apparently struck SUV door,
throwing cyclist off the bike to the left, in front of the bus.
Standard
  1-line
     Standard
       2-line
(Optional solid fender line)
“Safe zone”
   2-line
“Safe zone”
+ solid fender line
 “Safe zone”
+ dashed fender line

+”Door Tees”
“Safe zone”

Unmarked

                  Other innovations
4. Combined bicycle lane / right turn lane
• Eugene, OR trial
• FHWA evaluation found no conflicts
                    Other innovations
5. Colored bike lanes
• Portland “Blue Bike Lane Study”
• Several U.S. examples, including one in Sunnyvale
• Color, if standardized? Blue: unlikely (ADA). Green: likely
     Portland “Blue Bike Lane” Study
• 10 sites, 3 scenarios (vehicles weaving, merging, exiting)
• Special signs
• Observations (before/after)
   – Who yielded
   – Whether bicyclists
     checked over their shoulder
   – Whether bicyclists
     used hand signals
    Portland “Blue Bike Lane” Study
Group 1. Bicyclist continues straight through weave area
         before Right Turn Only Lane
    Portland “Blue Bike Lane” Study
Group 2. Bicyclist continues straight through
         across merge area
    Portland “Blue Bike Lane” Study
Group 3. Bicyclist angles left across exiting movement
Colored bike lane
Sunnyvale example
       Now for some
San Francisco innovations…
  “The Mayor disavows any knowledge of this
design being considered for Golden Gate Park…”
