Signallard / Public facility


Bollard at a crosswalk is a public facility which has been installed to protect pedestrians from vehicles. But for the blind, it can be a huge obstacles. To solve this kind of problem, we combined audio signal system which is installed at traffic signals to bollard, and to let blind pedestrians know the time to cross the street with sound.
