Graphic showing how much less space is needed to move more people on transit.

To carry 50,000 people per hour in each direction, a city needs a 175m wide road for cars.

Even if those cars are electric.

And then there’s all the parking.

OR a city can move A LOT MORE people in a lot less space, with A LOT LESS public money and pollution.
