Find the better trip, then try it.
Shift is a free app for finding better ways to get around, with live departures, bike share and routes for the trips you make.
See what’s moving near you
The next train, the nearest bus, how many Bluebikes are at the dock, and whether you’ll make it.
Plan a trip
Say where you’re going and compare walking, biking and transit, door to door.
Get rewarded when you try
Challenges, Walk/Ride Day drawings and prizes for trying a new way. Shift counts your trips on its own.

Green Streets Initiative
We help people shift trips to healthier, more affordable, more fun ways of getting around — and we measure the impact, trip by trip, community by community.
We started in 2006 with a monthly Walk/Ride Day in Cambridge. Twenty years on, the same idea runs through everything we do: make the better trip the easy one, then show people what it added up to.
Start with one trip.
Pick one trip this week — the school run, the coffee, the commute — and take it on foot, on two wheels, or on the bus.
