OpenTripPlanner 2.0 is the second major release of OTP, the result of several years of hard work and increasingly international coordination led by Entur in Norway. The transit routing engine of OTP2 has been completely rewritten, yielding major improvements in performance, scalability, and variety of itineraries over OTP1. It also has other important new features like the ability to read EU-standard NeTEx transit data and SIRI realtime.
