1 Lessons Learned from Cycle Tracks (Class IV Bikeways) Design Practice By: Min Zhou, P.E., Principal/Vice President KOA Corporation 1

2 What is a Cycle Track (Class IV) TYPICAL BIKEWAY CLASSIFICATION CLASS I CLASS II CLASS III 2

3 What is a Cycle Track (Class IV) BIKE BOULEVARD Shared roads with some preferential treatment for bicycles Traffic calming Quieter and more attractive Long Beach Vista Street Bike Boulevard Pasadena 3 Pasadena Green Street, Seattle

4 What is a Cycle Track (Class IV) Class IV - California Legislature Approval Exclusive Bike Facility On-Street Infrastructure Physically Separated from Motor Traffic and from Pedestrian Differ from Buffered Lanes Differ from Class I Bikeway Cycle tracks are bikeways located in roadway right-of-way but separated from vehicle lanes by physical barriers 4

5 Why Cycle Track? Who are We Planning For? Level of Traffic Stress Cycle Track 5

6 Cycle Tracks Current Practice Summary Project Features Long Beach New York City Washington D.C. Portland, Oregon San Francisco Left-Side Parking Yes Yes Yes Yes Yes Buffer Zone Yes Yes No Yes Yes Bollards/Berm Berm Bollards Bollards No No Bike Signals Yes Yes No No No Bike Boxes No No No Yes No Contraflow? No No Yes No No Reduced Traffic Lanes Yes Yes Yes Yes No Traffic Calming Effect Yes Yes Yes Yes Yes Pedestrian Safety Improvements No Yes No No No Streetscape Elements Yes Yes Yes No No Bike Lane Left/Right Side Left Left Left Right Right 6

7 Cycle Tracks No Caltrans Design Guide Yet! Design Features: Cycle Track Width Type of Separators Driveway Conflict Lost of Parking Spaces Intersection Treatments Bike Signals Signage Pvement Marking ADA Drainages Boulder, CO San Diego, CA Chula Vista, CA Santa Cruz, CA 7

8 One Way Cycle Track 3 rd & Broadway, Long Beach One-Way 9 Protected Bikeway 8 Parking Lane Two 11 Vehicle Lanes Sidewalk Added Bike Signal 5 Buffer Zone Raised Berm 8

9 Cycle Tracks Existing Cycle Track 3 rd & Broadway, Long Beach APWA 2012 B.E.S.T. Award 1.2 miles of Cycle Tracks for Two One-way Streets First Cycle Track Implemented In SoCal

10 3 rd and Broadway Issues Left turn signals delay Cyclist cannot back track Delivery Trucks Weaving Parking ADA Drainage 10

11 Cycle Tracks Left-turn Conflicts & Sight Distance Existing Typical Plan View Alternative 1: Contra-Flow Typical Plan View Alternative 2: Two-Way Cycle Track Typical Plan View

12 Cycle Tracks One Way Cycle Track

13 Cycle Tracks Contra Flow

14 Cycle Tracks Two Way Cycle Track

15 Cycle Tracks Left-turn Conflicts & Sight Distance LANE BIKE LANE BIKE Separate Bike/Ped and left turn phases Bikes approach from behind turning vehicles Ped Bike Left- Turn Thru lane Left turners receive red light Ped Bike Left- Turn Thru lane Bikes and pedestrians receive red light

16 Cycle Tracks Left-turn Conflicts & Sight Distance Oncoming bicyclists are more visible to drivers turning left Flashing yellow arrow signal provides a cue to motorists to be vigilant Ped LANE BIKE Bike Left- Turn Thru lane Flashing yellow left arrow during bike & ped phase Decreased delay time for pedestrians, cyclists, and motorists

17 Cycle Tracks Left-turn Conflicts & Sight Distance Separate Bike/Ped and left turn phases Oncoming bikes are more visible to drivers turning left, but bikes also approach from behind turning vehicles Ped Bike Left- Turn Thru lane Left turners receive red light Ped Bike Left- Turn Thru lane Bikes and pedestrians receive red light

18 Rosemead Blvd Cycle Track, Temple City 2 nd Cycle Track Implemented in Southern California America s 10 Best New Bike Lanes of 2014, Award by People for Bikes 18

19 Rosemead Blvd Cycle Track, Temple City Lost of Parking Spaces Avoid Right Hook Collisions 19

20 El Camino Real Two Way Cycle Track Design, San Clemente Existing Class II bike facilities on El Camino Real will be replaced by a combination of Class IV and II facilities along this well-used section of the Pacific Coast Highway Separated facilities for casual riders, pedestrians, & fearless riders; Lower vehicle speed; ADA compliance and signal modification 20

21 Cycle Track Concept Design, Pasadena Orange Grove Blvd from Green St to Wilson Ave (2.5 Mile) Peak Hour Volume (Veh) Vehicular Capacity (Veh/Hr) Traffic Lanes Existing 1,310 3, Cycle Track 1,310 1,600 2 *0* Buffered Bike Lane 1,310 1,600 2 *0* Daily Hours Over Capacity Parking Both Sides Both Sides Both Sides Parking Spaces Parking Loss Cost 248 N/A N/A $1,779, $217,000 * Thru traffic will be blocked by left turns. (No two-way left turn lane) 21

22 El Centro Street Cycle Track, South Pasadena Existing Parking Count 130 Proposed Parking Count 62 Percent of Parking Lost 52% 22

23 Santa Ana Downtown Complete Streets Cycle Track runs in the center of the street on Santa Ana Blvd Intersection Complication Avoid Conflict with Street Car 23

24 Recap: Lesson learned from Cycle Track Design Practice Choose between cycle track, buffered lanes, and bike boulevard Driveways Intersections Lost of parking spaces Traffic capacity reduction ADA issues with parking
