Migma has recently installed three double-sided MassDOT-approved RRFB systems at one crossing. In addition to two standard RRFBs with pushbuttons at two sides of the crosswalk, there is another RRFB without pushbutton at the median. All lights will start flashing simultaneously through two standard pushbuttons with FCC-compliant wireless communication modules. The entire systems were mounted on three 12’ x 2” square posts.
