Arrival time estimates are really difficult. I much prefer being able to see where the vehicle is on a map and make my own decisions, based upon my own experiences. However, I played around with one provider (Availtec's) estimations for Birmingham, AL's bus system. This looked at the GPS position of the vehicle to see when they actually arrived at a stop and back compared it to the running estimation time. As we can see, it isn't great. https://blog.line72.net/2019/08/06/validating-availtecs-bus-arrival-estimates/ https://blog.line72.net/2019/08/06/validating-availtecs-bus-...
