Pedestrian infrastructure audits for the City of Sydney’s Liveable Green Network

  1. 1. Pedestrian infrastructure audits for the City of Sydney’s Liveable Green Network Bryony Cooper and Larissa Miller
  2. 2.  Sustainable Sydney 2030  The Liveable Green Network  The pedestrian facility audit task  Approach to auditing  The audit criteria  Collecting the data  GIS tool  On site  Prioritising the works  Reporting and maps  Summary of data  GIS outputs  Maps Content
  3. 3.  A ‘Green, Global and Connected’ City  The ‘Five Big Moves’ to manage the City’s growth and to guide future strategic policies and infrastructure:  A revitalised city centre at the heart of global Sydney  An integrated Inner Sydney transport network  A Liveable Green Network (LGN)  Activity hubs as a focus for the City’s village communities and transport  Transformative development and sustainable renewal Sustainable Sydney
  4. 4. The Liveable Green Network What it achieves?.....connections to a more liveable city City Centre Village to village Parks and leisure
  5. 5. The Liveable Green Network The Liveable Green Network is made up of  LGN Priority Network  Citywide Pedestrian Priority Network  City Wide Pedestrian Cycle Priority and Primary Local Pedestrian Network  Primary Local Pedestrian Network
  6. 6.  Prepare a Pedestrian Access and Mobility Plan (PAMP) for the LGN  Focus on infrastructure audits and recommendations  Audit the four levels of network priority for:  Facility locations and quality  Amenity, access and compliance issues  Missing facilities  Intersection and crossing treatments  Path condition and widths The auditing task The City of Sydney wanted to audit the Liveable Green Network to identify gaps, issues and areas for improvement of the walking experience.
  7. 7.  Proposal-stage decisions  Calculate kilometres of network  Use hand held devices with GIS software  Project commencement decisions  Agree on audit criteria upfront  Recommend improvements on site  Trial and revise GIS data collection tool  Real-time upload of data The approach to auditing
  8. 8. Three types of data collection 1. Identification and recording of pedestrian infrastructure. 2. Assessment of pedestrian infrastructure. 3. Footpath width measurements against existing GIS footpath segment layer. The audit criteria
  9. 9.  The location of every non-footpath pedestrian facility was recorded by the site auditors, whether it had any associated issues or not.  Provided Council with an up to date inventory of all pedestrian infrastructure. 1. Identification and recording of pedestrian infrastructure
  10. 10. Every issue associated with pedestrian facilities was recorded by the site auditors.  Crossings: dimensions, alignment, condition, clear zones, signage, missing  Path condition: Cracked, uneven (severity: slight, moderate or severe)  Path obstructions: Street furniture, vegetation, bins, other (degree of impact on the Pedestrian Through Zone)  Sight lines: Conflict at driveways  Shared paths: signage, line-marking, pinch points  Shared zones: signage, presence of kerbs, pavement markings  Bus stops: clear space, tactile ground surface indicators  Accessible parking: lack of kerb ramps, adjacent path width 2. Assessment of pedestrian infrastructure
  11. 11.  Footpaths and shared paths  Update Council’s footpath segment GIS layer with the measured width  Different widths for paths on the priority networks  Specific measurements were noted as: below minimum, compliant and preferred  Also noted where paths were missing on the networks 3. Path width measurements
  12. 12. Collecting the data – GIS tool  Collector for ArcGIS IPad application  PAMP data was recorded for the LGN two ways:  Placing a point or line to indicate the presence of a pedestrian facility, record the issue if there were any and to recommend an improvement and;  Updating the footpath segments in the City of Sydney footpath layer to include a value for the measured width of each footpath segment.
  13. 13. Collecting the data – GIS tool

  19. 19. Collecting the data  The site audits were undertaken between December 2014 – February 2015.  A team of up to five people a day audited the LGN, focusing on one area of the City at a time.  Each team member had a measuring tape and used the tablet’s in built camera.  Each auditor required two tablets each day due to battery drainage.
  20. 20. Collecting the data
  21. 21. Eight weeks of audits
  22. 22.  Works were prioritised based on their location within high, medium or low priority areas throughout the CBD  New works were prioritised higher than upgrade works Prioritisation
  23. 23. Results Facility Total instances of the pedestrian facility Accessible parking 120 Bus stop 538 Footpath 4,729 Footpath segment widths 4,997 Kerb extensions 515 Kerb ramp 6,906 Laneway 7 Mid-block/pelican crossing 40 No crossing facility at this location 0 No footpath facility 0 Pedestrian bridge 9 Raised threshold at T-intersection 17 Other - subway 15 Pedestrian mall 37 Pedestrian refuge 229 Shared path segment widths 199 Shared zone 54 Signalised intersection 354
  24. 24.  The complete data collection was presented in a geodatabase for the City of Sydney. The geodatabase includes:  Unique point or line ID.  Location of pedestrian facilities.  Type and severity of pedestrian facility issues (if any).  Photo.  Recommended improvement (if required).  Cost estimate.  Priority.  Updated widths for the City of Sydney footpath segment layer GIS outputs
