RRFB systems are often activated by pushbuttons.
Statistically, during normal time, about 50% of pedestrians do not push the
pushbuttons when going across crosswalks or intersections. It is expected that
more and more pedestrians will no longer push the pushbuttons during and after
pandemic, which could potentially increase pedestrian injures or fatalities.
Migma Systems has developed
an alternative product, Distributed Sensing Flashing Beacon (DSFB). The sensor
receiver is embedded inside the housing of flasher, drawing power from solar
panel or solar battery. Using solar-powered detector, it flashes only when
pedestrians who are waiting at midblock curb are detected. Otherwise, it is off!
The sensor response time is less than 1 second. Moreover the detector and RRFB
can be installed on different poles or posts.
Some vehicle drivers can be easily distracted by devices such as smart phones
while driving. These distractions, caused by their devices, are well documented,
rising cause of pedestrian and/or vehicle accidents and sometimes fatalities.
Migma Distributed Sensing Flashing Beacon can make a difference!
