Know where your bus is any time with the new GRU Transit System App. The GRU Parking and Transportation department is pleased to announce the availability of a new app that will allow GRU transit passengers to view where their bus is. Available for both iOS (iPhone) and Android devices, users should search for Smarttraxx (Two t’s and two x’s) in their App store. Once downloaded they should select “Georgia Regents University” from within the app. “We are really excited to provide this tool for our passengers, they will always have a way to know where their bus is”, said Beth Bryson, Manager of Parking & Transportation.
