You’ve probably been here before: You’re using your phone’s GPS to drive around Boston’s confusing network of roads and highways, and you enter a tunnel.
Then, you encounter a fork. Right or left? You glance at your GPS, but it has no idea where you are. You make a wrong turn and end up miles out of your way.
Now, MassDOT and the navigation app Waze are teaming up to allow your GPS to follow you into those Boston tunnels with the installation of hundreds of navigational beacons.
