Website with routing on the public transport network(repost)

I need a Website that do routing on the public transport network. <strike>in the city of Bucharest (Romania). The data used is the OpenStreetMap.</strike> The design of the website can be a rough one, the important parts (that i consider at this time) is <strike>the maps extracting/using from the OSM and</strike> the routing algorithm. <strike>The two points must be done by you.</strike> The information on the bus/train/metro stops is available on paper/pdf/scan. A way to enter those info into a database that rest to decide. I removed the OSM/map part, for start the website will have no map, just listing of the route to take. I can help with some ideas as i have a background in computer science, but my major is IP Telecoms. I will provide a hosting service at DreamHost.
