Street Connectivity: Implications for Small Town Transportation Performance

This document explores the implications of street connectivity on small town transportation, specifically in San Marcos. It references various studies and maps, highlighting the importance of quality routes for cyclists and pedestrians. The need for improved infrastructure and low-stress routes is examined, as well as the significance of connectivity metrics such as average block length and intersection density. By analyzing existing pathways and their impact on mobility, this work aims to contribute to better urban planning and enhance transportation performance for small communities.

  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
