TTC Route Table Generator

Bugs listing

I wrote this program one evening trying to figure out a particularly difficult bus route. So there are bound to be many bugs. Here are some known issues:

• Bad TTC data -- I have yet to find a schedule that doesn't seem to have errors. The generator will try to make sense of them, but if something looks fishy, double check the official TTC schedule.
• Real-time updating -- though the tables are generated directly from the tables on the TTC website, this webserver won't allow me to download them on demand. (future feature for new server)
• Express busses -- they interfere with the algorithm to infer busses by changing the ordering in the schedule. If one (express) branch passes another branch, there might be a break in the table where the express bus jumps two columns earlier. (will handle express busses separately in future)
• Short turns -- impossible to detect ahead of time, a short-turn bus might capture the "end" of the next bus's route, if it's within 15 minutes. If there's an unusual delay between stops, this might have happened. (future work: detect and fix this by estimating interstop times)
• Last stop on route -- TTC doesn't list the times for the end of the route, so I can't include them in the table. (future feature, estimate arrivial time from opposite direction data)
• ... probably other bugs too. Let me know about them!
