I’ve started to make an LTC map synced with Google Maps so you can figure out if there is a bus near your position in London Ontario. Right now I have the 21/15 and 17 routes marked. It’s an AIR app, but I can easily port it to a SWF for use with Flash.
Be warned, there are a few bugs.
Update: Now synced with a MySQL database to find when the next bus will come. (There are only a few stops in there, so if there are some REALLY huge times or it says “bus is already there”, I haven’t put the next time in yet.)
