About GIS in Transit • Center for Urban Transporta5on Research at University of South Florida has hosted biennial “GIS in Transit” conference since 2009 (see www.transitgis.org)
• Accessibility is a key term – WMATA, for example, uses GIS to comprehensively track the accessibility of its services and facili5es
– Accessibility Observatory at University of Minnesota uses transit service data for demographic, geospa5al analysis
• Emergence of standardized, open data is enabling new genera5on of analy5cal tools – Oregon State/ODOT Research Project – SUNY Albany’s AVAIL (service analysis)
• Travel 5me reliability isn’t just a highway concept
Why?
• More informed decision making through visualiza5on
• Efficient support for user requests for data • Enable innova5ve performance analysis

Ingredients compass.its.pdx.edu!
Menu Planning compass.its.pdx.edu!
Prepare the Ingredients!
• Prepare GTFS data and set aside • Collect daily APC and AVL data • Clean the data based on error messages, mismatched ons and offs, more
• Aggregate by quarter for “typical” data • Be prepared for par5al people • Export data with enough fields to support GTFS matching

Step 1: Convert GTFS to Feature Class compass.its.pdx.edu!
Step 2: ArcPy converts padern lines to stop segments

Dessert (aka, next steps)
• Cartographic refinements – Line Offsets – Point symbology
• Integrate data visualiza5ons (pie charts & plots)
• Data download capability • Non-‐temporal queries
