Not sure I fully understand all of that (particularly "crowdsourced")...but if I get anything out of it, it is that GO/Metrolinx the agency that is supposed to be the the co-ordinating spine of a new regional vision of transit has gone onto google to offer it's route planning and is probably aware that the other agencies can't get on there so we have GO on google, BT on eRide Trip Planner.....who knows what the others are on and even on the web we can't seem to get our transit systems together! Perhaps it would have been better for GO to join with the other agencies and get route planning co-ordinated!
Crowdsourced just means that you get willing members of the public to do the work. Problem is, Google wants to know that the data is totally accurate so they want it to come from the transit provider, not someone else. For example, they would not accept TTC data from the myttc.ca folks.
Yes, GO/Metrolinx has gone onto Google. However, they are pushing other agencies to go there as well and information I've seen indicates that we should expect other local agencies to get there in the next year. That doesn't mean that they can't have their own planner on their own website, but Metrolinx is saying that they need to provide their data to Google. The goal here is to have a regional planner (as listed as a goal in the Metrolinx RTP document) so that you can plan a trip from anywhere to anywhere in the GTA, regardless of which systems you have to take to get there.
For many, this is NOT that big a deal given that most of them are using commercially-available transit planning software like Trapeze, so they've already got their route/schedule data in electronic form, and the vendors already have tools to export to Google. They just have to put the pieces together and get it done.
Right now, it's very possible that the holdup is at the Google end for some of these; Google says that they are not accepting new partners right now because they're having trouble keeping up with the ones they've got.
As for route planning, Metrolinx is pushing agencies to coordinate better but there is still a lot of work to be done there.
