  1. Street Connectivity: Implications for Small Town Transportation Performance Jen Duthie

  2. A Look at San Marcos

  3. Ref: San Marcos Bike Map, 2012 Easy Difficult Future Trail Intermediate Shared Use Path

  4. Why Connectivity Matters

  5. Ref: McNeil, N. (2010) Bikeability and the Twenty-Minute Neighborhood, Portland State University Master’s Thesis.

  6. Quality of routes to/from Ferry building (SF) Ref: Zorn et al. “Completing the Cycle: Incorporating CycleTracks into SF-CHAMP,” presented at ITM 2012

  7. Change in route quality to Ferry Building due to infrastructure improvement Ref: Zorn et al. “Completing the Cycle: Incorporating CycleTracks into SF-CHAMP,” to be presented at ITM 2012

  8. A constructed path may not be the desired path.

  9. Measuring Connectivity

  10. Craddock Ave RM 12 Average block length: 347 feet 176 intersections per square mile 100 four-way intersections per square mile Connected node ratio: 0.97

  11. Sessom Dr. Aquarena Springs Dr. Average block length: 487 feet 92 intersections per square mile 8 four-way intersections per square mile Connected node ratio: 0.56

  12. Incorporating Roadway and Intersection Characteristics

  13. Low-stress routes without intersection effects Low-stress routes with intersection effects Lowest Stress Most Stress Ref: Mekuria et al. (2012) Low-Stress Bicycling and Network Connectivity, Mineta Transportation Institute
