What is a cycle track?

Combines the userexperience of a separatedpath with the on-streetinfrastructure of a bikelane

Provides space exclusivelyfor bicycles

Separated from vehicletravel lanes, parking lanes

and sidewalks

Cycle tracks are located on the outside

of on-street parking

Fat tires less dangerof getting caught in tracks Slower speeds

Driveway Crossings

Continue the cycle track through the crossing

Use pavement markings and grade separation to

indicate that the cycle track has the right-of-way


24/49

Increasing Visibility at

Signalized Intersections Drop the cycle track to a

bike lane ~16 beforeintersection

Move vehicle stop-barback ~16

Stripe the cycle track as itbecomes a bike lane,potentially through theintersection, as acrossbike

Remove parking directlybefore the intersection

Right Turn Yield--Amsterdam


28/49

Crossbike

Parallel to crosswalk

Uses pavement markings toseparate pedestrians andbicyclists


29/49

Protected Signal Phases

Prohibit right-turn on redby cars and left turns by

bicycles

Provide an advance orseparate green signal forbicycles

Use bicycle-differentiated

signal heads Bicycle icon

Smaller signal

Located on near-side

Countdown to red/green

Longer signal phase

Right turning movements

Can separateautomobile right-turn

phase from straight-ahead bicyclemovements

Transit Conflicts

Cycle track crossing street car

tracks with yield markings

Cycle track passing between

bus stop and sidewalk

Cross at as close to 90 degree angle as possible

Yield signage or pavement markings

Minimize conflicts between disembarking transit passengersand cyclists in the cycle track

Cycle Track Lessons Learned

One-way each side of a street

Minimum 2.0 m. clear; 3 m. in higher-demand situations

Cycle track located between sidewalk & on-street parking

Driveways and low volume side streets yield to cycle track European standard is to use yield control pavement markings, not

stop signs at low volume intersections

Driveways and low volume side street crossings can be marked,colored, textured

Motorists must mount curb to cross

Cycle Tracks Lessons Learned 2

Cycle tracks at intersections

Separate signal cycles for right-turning motorist versus through biketraffic

Stop line for motorists pulled back 16 (can use bike box or pulledback stop line)

Can drop cycle track to bike lane 16 back Use color in bike lane starting 16 back can use color through

intersection Advance green Use of yellow warning before green (2 secs) No right turn on red for any movements No parking at intersections (16 back) Twp-step left turn in many situations

Buses stop outside cycle track and can be separated cyclists in cycle track yield to disembarking passengers

Wayfinding/naming signage should accompany the system

KeyDesign Issues forPortland


48/49

Key Design Issues for Portland

Adequate width (2.2 Meters) for cycletrack

Cycle lane treatment at intersections

Retrofit drainage for raised cycle

track. $ Develop cycle track designs that are

compatible with green streets. ADA compliant crossings and transitstops
