Transit data

• arrival times of subways
• number of riders at different times
• how often trains/buses are running; time between
• where the bus is
• performance of transit - cancelations, delays
• bus speed
• location of boarding / exit
• missing the people who don’t have (convenient) service already
• how demand changes daily / annually / seasonally

Transit

• subway efficiency
• calculated demand based on number of people on the train at various times

• Ethical issues

• by overlooking certain people in collecting data we may be underserving those who need it
• mostly we schedule around business hours - who tends not to work those hours?
