Metro Transit?s embrace of green technology keeps rolling as riders can now plan their trips using Google Maps and use GPS data to track bus locations and arrival times on smartphones and PCs. Metro is also promoting applications created by third parties. Aleksandr Dobkin, a UW-Madison graduate, developed a Bus Radar application for Android, while Jignesh Patel, also a UW-Madison graduate, developed an app called Locomatix for iPhone and Blackberry.
