things im worried about:
I think we should to speak to someone at the bus company and find out
if they will let us put these things on there.
things i know nothing about:
if we do make them to keep them running why not put them on top of the
bus and charge them with a small solar cell? does a bus move fast
enough that we can put a fan up there grafted to one of those crank
things im pretty sure about:
I ride the bus pretty often, and have really never had to wait 20
minutes at the stop(ymmv). my feeling is that we could simulate the
routes and display the bus locations on a map(in a format that looks
just like "Magic Bus" if we want) and our audience would assume its
live data and be just as impressed, while we havent spent a dime.
If the buses are running late by 2 minutes (according to our site), is
Bob going to risk getting to the stop late on the assumption that the
bus hasnt caught up to schedule between his between looking at the
site and walking to the stop....i doubt it. my guess is hes going to
get there at the time its supposed to arrive "just in case".
the job of public transport is to be on time, and they do it pretty
well here. if the bus gets there early, it waits. you'll never miss a
bus by getting there at or before the time its supposed to be there. i
have never been disappointed or had my plans ruined by the bus schedule.
you know, in this crazy mixed up world we live in, it seems like a
great idea to help people have better access to public transport, and
any kind of planning aid we can provide them. reinventing what the
bus-schedule ( as an interactive map with up to the minute
information) is a fantastic idea. Trying to implement a system that
requires _a lot_ of time, money and upkeep seems a little optimistic
to me. When the gains to be made over a non-sensor based site are
minimal at best, it seems like (and dont get offended) a big waste of
time, money, and hacker brain power.
that said -
the CCTA site is LAME and is pretty much an electric pamphlet, if we
include other buses that run downtown in our system, and allowed
people to figure out transfers and walking directions (a la
hopstop.com) we would be providing a much better service to the
student body than letting them know that their bus is going to be 1.6
getting hopstop functionality in our small city would be cool (and hip!)
cheers and apologies for being the guy whos saying all this,
