They are clearing the streets.

Signs are posted announcing a temporary ban on parking.

An event is on the way. People are on their way.

It will get crowded, excitement charging the air, then it will be back to the usual pattern. Every day people will park, then return to their cars and drive away.

Perhaps the event is the “usual pattern” and when the signs come down there is a pause between one batch of the usual and the next. Perplexing.
