Ford's ACT, short for Automatically Controlled Transportation or Activity Center Transit, was a people mover system developed during the 1970s. One interesting feature of the ACT is that it allowed bi-directional travel on a single rail—cars passed each other by switching onto short bypass lanes on the track, distributed where space allowed. ACT was a contender in the Urban Mass Transportation Administration's plan to deploy three or four systems in cities in the United States, as well as the GO-Urban project in Toronto, Canada.
