Many tout the need for 5G to power self-driving cars. For an autonomous vehicle to smoothly travel through a city, it will need to have low latency that allows it to continuously “see” its surroundings. 5G will allow for smart traffic lights, which connect with cars on the road to improve traffic flow. Carnegie Mellon University and Pittsburgh tested the use of smart traffic lights. The result? A 40 percent reduction in vehicle wait time, a 26 percent faster commute and a 21 percent decrease in vehicle emissions.
A 5G network will also make the roads safer. For example, as a car enters an intersection, a smart traffic light will notify it that a pedestrian has just hit the “walk” button, which will provide drivers more warning. Ambulances will be able to change traffic lights faster to accommodate their route and clear intersections.
