Movement for Liveable London Street Talks - Stuart Reid 10th January 2012

  1. 1. Shared Space Insert relevant colour image here and send to back Stuart Reid – MVA Consultancy
  2. 2. What is Shared Space?
  3. 3. What is Shared Space? <ul><li>Assert Place status without vehicles being: </li></ul><ul><li>excluded </li></ul><ul><li>or </li></ul><ul><li>overwhelming streets </li></ul>
  4. 4. Uses Design… Before
  5. 5. … to achieve behavioural outcomes After
  6. 6. Not A Design Type
  7. 7. Delineation Sloane Square Shared Space New Road Brighton Seven Dials High Street Kensington Camden Town Oxford Street The Cut Mixed Priority Routes Paternoster Square Pedestrianisation Peascod Street Exmouth Market Blackett Street Woolwich Town Centre Ashford Ring Road Exeter High Street Lisle Street, Soho Plymouth Town Centre Home Zones Lamb’s Conduit Street Brick Lane Soho Square Shaftesbury Avenue / Charing Cross Junction (weekend) Old Compton Street Interaction between Modes Shaftesbury Avenue / Charing Cross Junction (weekday) Woking Town Centre Broadwick Street Flexible Space Bath, Somerset Clifton Road, Maida Vale Great Russell Street
  8. 8. Not Always A Level Surface <ul><li>Before: </li></ul><ul><li>Engineered approach </li></ul><ul><li>Priority to vehicles </li></ul><ul><li>Peds have to ‘call’ to cross </li></ul><ul><li>Corralled by guardrail </li></ul>
  9. 9. <ul><li>After: </li></ul><ul><li>Peds reclaimed space </li></ul><ul><li>New Plaza </li></ul><ul><li>Road function still intact </li></ul><ul><li>30mm kerbs </li></ul>
  10. 10. Street Design Influences User Behaviour
  11. 11. Vehicle Speed - Regression Analysis <ul><li>Regression model including shared space rating, explained 65% of variation in vehicle speeds </li></ul>R Squared value: 0.654 No. Observations: 993 <ul><li>Models suggest following assist in decreasing traffic speed: </li></ul><ul><ul><li>higher pedestrian volumes </li></ul></ul><ul><ul><li>reducing demarcation between footway and carriageway </li></ul></ul><ul><li>However, whereas individual site characteristics can assist in influencing vehicle speed, need to design the space in totality to gain maximum affect </li></ul>
  12. 12. New Research - Who Gives Way to Whom <ul><li>Pedestrians gave way in most ped/veh encounters (69%) </li></ul><ul><ul><li>BUT differed significantly by site </li></ul></ul>
  13. 13. Street Design Can Increase Ped. Freedom
  14. 14. Relative Densities (1) Generally the more shared sites (New Road, Seven Dials and Y Maes) had a higher proportion of people using the carriageway than the other sites
  15. 15. Regression Analysis (1) <ul><li>Developed simple & multiple regression models to determine extent percentage pedestrians in road can be explained by existing data </li></ul><ul><li>Model only explains 34% of variation in the dependent variable, therefore other variables not captured explaining more </li></ul><ul><li>However, it implies: </li></ul><ul><ul><li>The lower the vehicle flow, the more pedestrians are likely to use the carriageway space </li></ul></ul><ul><ul><li>That pedestrians can be encouraged to use the carriageway space through its design (e.g. reduced demarcation between the footway and the carriageway) </li></ul></ul>R Squared value: 0.34 No. Observations: 398
  16. 16. Street-users affect each others’ behaviour
  17. 17. New Research - Who Gives Way to Whom <ul><ul><li>More drivers give way at or below 15mph </li></ul></ul><ul><ul><ul><li>Sharing - dynamic process – feedback </li></ul></ul></ul>
  18. 18. A Functional Equivalent To Kerbs
  19. 19. Corduroy Tactile Paving Tests <ul><li>800mm corduroy paving tested </li></ul><ul><li>Fail rate: 1 VI ‘fail’, no MI fails </li></ul><ul><li>Detection ease: </li></ul><ul><li>- Average VI 84% corduroy easy to detect, 94% </li></ul><ul><li>blister (91%/93% Pamela) </li></ul><ul><li>- Harder at acute angles (but detected earlier) </li></ul><ul><li>False detections: more at acute angles </li></ul><ul><li>Point of detection: 72% (average) detected </li></ul><ul><li>in first half, 88% (average) first 3/4 of delineator </li></ul><ul><li>No change in anxiety or tiredness </li></ul>
  20. 20. Local Transport Note 1/11 <ul><li>To be published October 2011 </li></ul><ul><li>Supporting research also published </li></ul>
  21. 21. Have Clear Objectives…and monitor them
  22. 22. Put It Where It Will Be Used
  23. 23. Design Inclusively
  24. 24. Keep Design Speeds Low
  25. 25. Events and Challenges…
  26. 26. Design It As A Dynamic Process
  27. 27. Address The Whole Place Less Shared Design More Shared Design High tonal contrast between vehicle and pedestrian areas Low tonal contrast No tonal contrast Kerbs Low kerbs No kerbs Demarcation by surface drainage channel No surface drainage channel Pedestrian barriers No pedestrian barriers Vehicles restricted to parts of street, e.g. by bollards No barriers to vehicle movement Poor public space characteristics Presence of features such as cafes, markets, seating, planting, public art, etc. Conventional road markings Limited road markings No road markings Traffic signals No signals Signal controlled crossings Zebra crossings Informal crossings only
  28. 28. Enable Pedestrians To Choose To Interact
  29. 29. Ladder Grid
  30. 32. Keep The Clutter Down
  31. 34. Summary
  32. 35. Evidence Indicates <ul><li>Design can slow traffic </li></ul><ul><li>Design can encourage freer pedestrian behaviour </li></ul><ul><li>Overall design more influential than single features </li></ul><ul><li>Pedestrian behaviour influences driver behaviour (and vv) </li></ul><ul><li>Behaviour – interpretation not communication </li></ul><ul><li>Disabled people can benefit, if they feel safe </li></ul><ul><li>Visually impaired people rely most on the building line </li></ul><ul><li>Lack of a kerb is a problem for some VIP </li></ul><ul><li>Corduroy paving is a detectable boundary </li></ul>
  33. 36. Design Principles <ul><li>Know what it’s for </li></ul><ul><li>Design inclusively and engage with users </li></ul><ul><li>Speeds <15mph if possible – hard and dynamic elements </li></ul><ul><li>Understand what drivers will see </li></ul><ul><li>Places where people want to be </li></ul><ul><li>Enable pedestrians to colonise the space.. </li></ul><ul><li>… but don’t force them to </li></ul><ul><li>Design around people, not features </li></ul><ul><li>It’s just good design! </li></ul>
