There is no such thing as "sleep mode". It is just a different mode of operation; the intersection is fully powered and on when in "all ways blinking" mode. All ways blinking is for traffic efficiency, it doesn't save power. Small town Ontario Canada definitely does this. Source: grew up with blinking mode, thought it was normal everywhere until moving to the Big City after high school.
