I am intending to develop in the near future a web app for planning a route using my local public transportation system. I will be using Google Maps and I would like to hear some tips on how should I start planning this project for maximum efficiency (how should I store the stations, lines, times for each line, common stations etc, and also how to draw a route following roads - not just a straight line between two points). Thank you!

Since this Google service is unavailable in my country, I need to map all stations and then generate the desired routes. – linkyndy Jan 10 '12 at 20:50

Using the method described in that post may violate Maps Terms of use, and is undocumented and therefore not guaranteed to be around. – Mano Marks Jan 10 '12 at 21:34

There's a defacto standard way to encode and interchange transit data. Lots of transit agencies are releasing their data in Google Transit Feed Spec format. You might check to see if your agency has already done so. There are also open source tools for dealing with GTFS. For instance: http://code.google.com/p/googletransitdatafeed/

My agency is far from doing so, far even from informing its clients when do the trams/buses arrive at each station. That's the many reason I intend to develop this app. I don't want to do their "job" (i.e. submitting all that info on the link you posted); I simply wish to make my own database, only with stations, lines, and some arriving times which I'll get by using some sort of algorithm. I wanted only to know what's the best way to organize my data (I'll be using MySQL), and how would I "draw" the route a user requests between two points (mainly, how to draw a line which follows a road). – linkyndy Jan 10 '12 at 22:12
