Make sure it is named correctly in your Google Maps JavaScript api - grtapp.ca/lakeontario.js if you’re lazy

@ioncrashcounter.com so this happened 😕 www.therecord.com/news/waterlo... LRV not confirmed but suspecting 509 as according to transee it went offline then right under the Weber bridge as it was heading to Fairway, and it looks to be the only train in service yesterday that’s not in service today

*The GRT Stop closure assistant*: GRT sends these stop closure notices, such as this one active today. So how does this affect me? My effort to try adding to these notices somewhat with my app:

Trying some UI things - parse service alert notices to indicate closed stops on trip page map 🤔

@canardiain.bsky.social how do you like this way for my app to show the upcoming LRV numbers? Someone suggested this icon 😆

Grand River Transit app grtapp.ca finally supports real time trip updates for bus & LRT 😃 (well it’s real-time ish as it’s a couple of minutes between data reloads for performance reasons, but hopefully it can still be helpful. There’s still the option to send a text). Built without AI!

Hmm… I would have thought a transit app that does not use AI would get a bit more interest here 🤔 anyway, any feedback welcomed

I have finally figured out how to provide real-time data on grtapp.ca 😃 (thanks to transitland apis) service alerts will now show on the main page, and on stop pages of applicable routes. Will work on getting trip updates at a later time. 0% vibe-coded 🙂

I have been saving GRT GTFS files since 2018 as part of updating my app and have organized it on github for anyone who may be interested in looking back and comparing github.com/jason897/grt...

@ishrionaviation.bsky.social hey there, wondering if you’ve noticed any updates to these plans ishrionaviation.com/news/air-can..., because I had added the first LAS flight here in Flighty previously and it just notified me that it went from 763 to 788. Looks like some others changed also
