Yah, I typically don't need a computer to tell me that. It probably won't tell me when someone is getting in their car two blocks away and be a likely candidate to be in my way when I get there, or if there is a line of traffic at the light that will take a while longer to get moving after the light. Or if there are pedestrians approaching a crosswalk. I can time the end of the train and the clearing of the cars pretty well myself. I encounter a LOT more than stoplights.
It's a good start, but I'm sure I will hypermile circles around any such system for a long time to come
