Engineers at the University of Texas at San Antonio (UTSA) are developing a smart stop sign to reduce accidents on rural roads.

More than half of all road fatalities occur on rural roads, says the U.S. Department of Transportation. Those roads make up about 70 percent of the country’s byways—but many of them don’t have access to a power supply and are far more likely to not have lighted traffic signals and active traffic signage. This can make them hard to see, increasing the possibility of a crash…

The stop sign uses multi-pixel passive infrared sensors that detect a vehicle as it approaches an intersection. Once the vehicle is within the sensing range, a signal beacon triggers flashing lights on the stop sign—giving the driver enough time to slow down and stop safely based on how fast they are driving.
