background
Background
  • South Coast British Columbia Transportation Authority (SCBCTA, aka TransLink)
    • We plan, finance, implement and champion an integrated transportation system that moves people and goods safely and efficiently, supporting Metro Vancouver\'s regional growth strategy, air quality objectives and development.
  • Planning Division
    • Our main responsibilities revolve around strategic policy and planning, transit planning, project planning, road and infrastructure planning.
geocoding surveys
Geocoding & Surveys
  • Need
    • Marketing surveys, travel surveys, attitude surveys
  • Existing Software
    • Good and bad…
  • Development of standards
    • Improve quality, efficiency, and functionality
  • Benefits of FME
    • Control the process
    • Customize based on the data available
    • Customize the outputs
geocoding obstacles
Geocoding Obstacles
  • Varying sources of information
    • Postal Codes
    • Cross Streets
    • Shopping Centres
    • Places
    • Address
  • Naming conventions
    • “W 10th Ave” vs. “West 10th”
  • Log file
    • How many points matched? (od pairs, many points)
    • How usable is the data?
    • Where are the issues?

what to start with
What to Start With?
  • Network
    • Road network (or other)
  • Unique segment ID’s
  • Directionality
    • Segment geometry
    • Travel movement
  • Turning restrictions
  • Other cost information (numerous sources)
turn travel tables
Turn / Travel Tables
  • Turntable
    • The turn table contains the cost for turning or moving from one segment to another.
  • Traveltable
    • The travel table contains the cost for traveling along the entire length of a segment.
basic reasoning
Basic Reasoning
  • How does movement along a network translate to tables?
table relationship
