busAlert.me was a PHP app that allows people to receive SMS or voice notifications to be sent to your mobile device when their bus is getting close to its stop. It worked on all King County Metro stops in the Seattle area. Real time tracking information was provided by OneBusAway. SMS and Voice gateway though Twilio.
If you are outside of Seattle and want to create a similar system or want to help with development please checkout the code on GitHub: https://github.com/BrookeDot/busalert-me
