“It’s a constant effort to modernize our system; make the ride safe, reliable; and make sure that, because of time – which is so essential for people from home to work, for their kids going from home to school – we now have technology to enable people to better manage their time, and be more efficient; and when they’re on the system to make that a reliable, secure experience for them,” Mayor Rahm Emanuel said Friday morning.

The signs take advantage of GPS systems on every CTA bus to determine how soon buses should arrive at each stop on their route. It allows riders to plan ahead buses are running late.
