hello. i need to build an app which will be a "Trip Planner" not unlike what you see here, which they call their "
Journey Planner"
mine doesn't have to be the most complex, all the bells and whistles type thing like the one at my URL example, which even calculates bus fare, but i will need to be able to access several different bus line schedules-- in my city they are identified by letter, as in, "take the 'N' route to the 'V' route to the market, then take the 'NV Express' home".
i'm not sure exactly what will be involved, but i'll have to enter a lot of "bus stop" info, and time-of-day info. i'm still formulating the concept in my mind, but if anyone has ever tried something like this, of if you know of a tutorial, or anything that might help me, ideas on which
PHP Functions i should study, or Functions i should make, etc-- even other URL examples as i've provided above-- i'd greatly appreciate it. thanks!!!
i look forward to reading your replies.

am i crazy for taking on this project? to me, it doesn't seem like it's going to be all
that difficult. we don't have that many bus schedules for one thing, so it's not that much data for me to even work with. maybe 20 at the most. probably more like 10 different routes.
