I'm first time trying to use GTFS(General Transit Feed Specification) with Google Maps as per the Google developers page i have understood the concept of .txt files which are used as feed and for making a demo i downloaded a transit zip files from Google developers page. but I'm not getting how to use those transit files to show information on map. I tried to search tutorial for the same but could not find anything useful. Do i need to parse all those files to show in map or there is something different implementation.
I'm confused.
Please bear me with my lack of knowledge regarding GTFS.
