Transcript

  • 1. IMPROVINGBIKE SAFETY & ACCESSIBILITYON SHATTUCK AVENUE<br />SEUNG YEN HONG<br />MAY 9, 2011<br />
  • 2. Outline<br />Introduction<br />Literature Review<br />Cyclist Survey<br />Design Recommendation<br />Conclusion<br />
  • 3. Introduction<br />Goals <br />To study what kinds of street treatments could be implemented to improve bicycle safety and accessibility on Shattuck Avenue in the downtown area<br />To propose a schematic street design that will render Shattuck Avenue a complete street. <br />
  • 4. Study Area<br />
  • 5. Introduction<br />Background<br />Downtown Berkeley as pedestrian-oriented and bike-friendly place<br />Mode Split for Berkeley and Other California Cities (U.S. Census 2000, Journey to Work)<br />
  • 6. Introduction<br />Cyclist-involved collisions <br />in Downtown Berkeley (source: City of Berkeley)<br />Issues<br />Lack of north-south bike routes<br />Bike collisions on Shattuck Avenue<br />
  • 7. Introduction<br />Issues<br />Shattuck Avenue is a transit-priority street<br />Balance between the safety of cyclists and pedestrians, and the efficiency of busoperation.<br />
  • 8. Introduction<br />Complete Streets<br />Provides safe access for all modes of travel and for all ages and abilities (National Complete Streets Coalition)<br />Steve Price’s complete street vision in Portsmouth, Virginia<br />
  • 9. LITERATURE REVIEW<br />
  • 10. Literature Review<br /> Do bike facilities affect cyclists’ route choice?<br />Travel time v. Safety<br />Bicycle commuters value time over safety (Bovyand Bradley, 1985; Aultman-Hall et al. ,1997)<br />Safety-cautious cyclists spend more time to use facilities deemed safer (Hopkinson and Wardman, 1996; Tilahunet al., )<br />
  • 11. Literature Review<br />What kind of bicycle facilities would make Shattuck Avenue a safe bicycle route? <br />Bikeways<br />Intersection treatments <br />Bus stop design minimizing bus-cyclist conflicts<br />
  • 12. Literature Review<br />Bikeways<br />Separated bike paths v. bike lanes v. shared lanes<br />Barriers: limited right-of-way and high costs.<br />Issues: pedestrian-cyclist conflicts and “right-hook” accidents<br />Ninth Avenue Bike Path in New York<br />
  • 13. Literature Review<br />Intersection treatments<br />Color treatments<br />Bike boxes<br />Outward placed bike crossings<br />Dutch style junction design (Mark Wagenbuur, 2011)<br />
  • 14. Literature Review<br />Bus stop treatments<br />Shared bike/bus lane<br />Cycle track behind bus stops<br />Bus stop island in Denmark (Pucher, 2010)<br />
  • 15. CYCLIST SURVEY<br />
  • 16. Cyclist Survey<br />Purpose<br />Assess cycling conditions<br />Investigate the behavior patterns and preferences of cyclists in Downtown Berkeley <br />
  • 17. Cyclist Survey<br />Method<br />Intercept survey<br />Bike station survey<br />Online survey<br />
  • 18. Cyclist Survey<br />Results<br />Total 210 responses; 70% online survey<br />Experiencedbicycle commuters.<br />49% of all participants are older than 40.<br />More male cyclists (125) responded to the survey than female cyclists (79).<br />
  • 19. Shattuck Cyclists (67) v. non-Shattuck Cyclists (143)<br />Cyclist Survey<br />
  • 20. Cyclist Survey<br />Shattuck Cyclists<br />Are younger than non-Shattuck Cyclists<br />Depend on their bicycle as their daily mode of transportation<br />Prefer faster routes to safer routes<br />Prefer both bike paths and bike lanes<br />Yet, they tend to avoid traffic<br />40% of Shattuck Cyclists ride on sidewalk to avoid fast or heavy traffic <br />
  • 21. Cyclist Survey<br />Dangerous cycling<br />About 60% of Shattuck Cyclists experienced dangerous situations. <br />Intersections, parking bays, andbus stops. <br />Most dangerous intersections at Center Street and at Allston way due to nonlinear street layouts, high pedestrian and bus traffic, parking bays, and road congestion.<br />
  • 22. Cyclist Survey<br />Summary<br />Provide bike facilities on the high collision areas such as intersections, bus stops, and parking bays. <br />Different strategies for the two cyclist groups<br />E.g., separated bike paths to attract non-Shattuck Cyclists.<br />
  • 23. DESIGN RECOMMENDATION<br />
  • 24. Design Recommendation<br /> Goals<br />Complete street: take back pedestrian and cyclist right-of-wayfrom motorists.<br />About 80% of public ROW is dominated by motorists.<br />Wide travel lanes and parking bays hinder transforming Shattuck Avenue into a complete street. <br />
  • 25. Design Recommendation<br /> Based on Street and Open Space Improvement Plan<br />
  • 26. Design Recommendation<br /> General design guideline<br />Bike paths or lanes when ROW is available (parking bay elimination) <br />Coloredtreatments <br />Colored bike boxes and outward bike crossingsat intersections<br />Cycle tracks behind bus stops<br />
