Road accidents kill around 1.3 million people and injure tens of millions more each year, according to the World Health Organization. A start-up based in Dubai and Detroit is among those testing advanced technology solutions that could bring those numbers down. Derq is developing systems to better understand where danger spots are. The company uses a combination of sensors on roads, artificial intelligence, and computers in cars to notify drivers of potential hazards.[...] In many cities, these intersections already have cameras, so Derq aims to partner with the cities to make use of these cameras.
