The only book that has a sequence like that is STAR KA'AT WORLD.
Here, once our pre-teens get to the Star Ka'at world they are housed in a building that they can either get food by thinking it, or by a more technical method.

In most of the Andre Norton books - if you are trapped in a building, you better have your own food. I don't know of any book that includes a Traffic Light.

Here's a short list of Andre Norton Juveniles: The books that have teen agers. There are also about a dozen Young Adult books, but none of those range a bell with your plot synopsys.
