  1. CommunityConnectivity Analysisto Support Active Living Brent Turley, PE BMPO Joint Policy Board/TAC Meeting November 9, 2011

  2. The Nexus? • Connectivity: The quality of a network to facilitate travel between two points. • Good connectivity means removed barriers to travel • Good pedestrian and bicycle connectivity means greater opportunity for active living trips • Connectivity can be a performance or priority metric • Connectivity can be one of several metrics to evaluate active living policies over time

  3. Point-to-point GIS routing? Thedirect measure of connectivity

  4. B A/B Route Directness Index Distance Decay Score A 91 71 B ViaCity Score 81

  5. Example With Connectivity Projects Existing

  6. Other connectivity metrics?

  7. BMPO Analysis Local Examples

  8. Study Locations • Downtown • Schools (2) • Parks (2)

  9. Are these destinations well connected to surrounding areas? Analysis Process • Select parcels/building within 0.5 mile buffer around site • Enhance street network to create pedestrian network • Assign pedestrian quality to each network link • Calculate connectivity metric (ViaCity score) • Review results, run/compare scenarios

  10. Downtown • Good sidewalk coverage • Barriers: • River • Railroad • Yellowstone Hwy • S Boulevard

  11. Downtown • Scores: • Average = 65 • Over 60 = 73% • Problem areas: • Northeast • South • Southwest

  12. Tautphaus Park • Few sidewalks near park • Barriers: • Rollandet Ave • S Boulevard • Park access points • On-site network

  13. Tautphaus Park • Scores: • Average = 53 • Over 60 = 29% • Problem areas: • Points west • Southeast • Adjacent streets

  14. Sand Creek Middle School • Set back from arterials • Barriers: • Canal • Paved connections to west • Arterials

  15. Sand Creek Middle School • Scores: • Average = 54 • Over 60 = 32% • Problem areas: • North (canal) • West (multi-family)

  16. Iona City Park • Recent pathways • Barriers: • Some arterials sections • No defined routes

  17. Iona City Park • Scores: • Average = 63 • Over 60 = 56% • Problem areas: • Defined routes

  18. Eagle Rock Jr High School • No sidewalk along collectors or arterials • Barriers: • Broadway St • Skyline Dr • PancheriDr

  19. Eagle Rock Jr High School • Scores: • Average = 54 • Over 60 = 49% • Problem areas: • Crossing Broadway • Crossing Skyline

  20. Eagle Rock Jr High School Link Ranking • Another metric • Aggregation of shortest paths from each parcel • Potential high priority links

  21. Summary Statistics

  22. Examples Before & After

  23. Eagle Rock Before • Scores: • Average = 54 • Over 60 = 49%

  24. Eagle Rock After • Scores: • Average = 57 • Over 60 = 49% • Project: • Crossing Skyline

  25. Eagle Rock Change • Parcels impacted: • Change > 5 = 163 • Change > 20 = 132

  26. Sand Creek Before • Scores: • Average = 54 • Over 60 = 32%

  27. Sand Creek After • Scores: • Average = 56 • Over 60 = 35% • Project: • Yard crossing

  28. Sand Creek Change • Parcels impacted: • Change > 5 = 113 • Change > 20 = 66
