You might have noticed a little box attached to the signs for the Rectangular Rapid Flashing Beacons (RRFB) at the crosswalks between the Mount Vernon Trail and Memorial Bridge. What is it? Are you on Mount Vernon Trail Candid Camera?
The box is there to automatically detects people approaching the crosswalk and activates the RRFB to improve safety at the trail crossing. The RRFBs were installed as part of the Memorial Circle Safety Improvements which also included lane reductions at multiple crossings. The automatic detection was installed after post evaluation of the project determined that a low percentage of trail users were using the button to activate the RRFBs.
