14. -Transit Accessibility Index (TAI)
• Measure:
– Particular location (venue)
– Time and day of week
– Independent measurements:
• Originating locations independent of destinations
• Terminating locations independent of origination
• Definition: Accessibility: service w/i 1 mile
at desired time and day
