Publish data to the Web so that app developers can access it. Right now, you can plan a trip with Google, but developers can't access that data to develop other useful apps. Also, VTA has an AVL system - it would be great if real-time vehicle location and arrival time estimation was available. This could also allow installing real-time arrival signs at busy stops.
If this info was made available to developers, they could create great apps for riders to use to access the data, making the VTA more attractive without costing anything beyond the cost of publishing the data
