Brand new bus priority signal - Main street at Broadway

This new bus priority signal was added to the northeast corner of Main and Broadway this week. I believe it is activated by radio? Not fully sure though. I noticed an antenna near the bus waiting spot. This new signal is there to speed up buses and minimize the effects of the temporary closure of Broadway between Main street and Quebec street.
