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)

Rest API

Thanks mapperz for your answer. I started exploring OTP. i also check there web API (REST) but i have a little confusion that does i have to build OTP on my PC (as explained on github) or i can just use there web API and can access there webserver (as google transit does). – K G Dec 6 '12 at 17:55
