I am going to develop a journey planner (like Google transit), i was just wondering that if there any opensource API available that can help me, or i have to do every thing on my own. And where can i find some help to get started. kindly help me out . Thanks.
Open Trip Planner (Developer Section)
OTP Deployer — The easiest way to get started with OTP is by using OTP Deployer, an web-based utility provided by OpenPlans Transportation. Deployer allows users to simply provide their transit data in the standard GTFS formay, and the rest of the process — from gathering street network data to building the graph object to launching a live OTP web applcation — will be automated om Amazon’s Elastic Compute Cloud (EC2) platform. OTP Deployer can be used to simply build graphs remotely (free of charge) or launch and host a full OTP deployment (one-week “preview” hosting is free; long-term paid hosting can also be arranged)
