O#

On-Time Performance#

abbrev. “OTP”

An assessment metric for the quality and reliability of public transportation services.

On-Demand Route#

a.k.a. “Demand-Responsive Transit”

A type of public transport service with a route and/or schedule that is responsive to passenger demand.

Examples of On-Demand Services include:

  • Dial-a-Ride

  • Taxi

An interesting example would be Hong Kong’s Public MiniBus services, which generally have predetermined fixed routes but drivers can stop at any intersection along the way that a passenger requests (as long as it is safe.)
