Alley Traffic Lights

We don’t often think of congested alleys but in Korea they’re some of the busiest intersections where over 40% of accidents occur. Like a traffic light, the AISA is a 3 or 4 way signal. It’s made of titanium alloy with a round shape  to disperse direct forces. Small camera based sensors detect whenever foot, bike, or motor traffic approach and warns cross traffic with flashing LEDS. The color indicates the degree of danger and the flashing rhythm denotes speed. It’s not meant to control the flow of traffic like a stop light but it does give you a sense of what’s coming ahead.
