# A/B Street
Ever been on a bus stuck in traffic, wondering why there are cars parked on the
road instead of a bus lane? A/B Street is a game exploring how small changes to
a city affect the movement of drivers, cyclists, transit users, and pedestrians.
Ever been stuck in traffic on a bus, wondering why is there legal street parking
instead of a dedicated bus lane? A/B Street is a game exploring how small
changes to a city affect the movement of drivers, cyclists, transit users, and
