The more information available between the vehicle and the infrastructure, the more streamlined the flow of traffic can be. It's simple little things like we see on the Queen Elizabeth Way and in Mississauga, and you see it in California. It's just putting in lights that are monitoring the flow of vehicles. It looks like you're slowing people down. You're actually dramatically increasing the flow.
When accidents happen, if you look at the statistical progression, for every second on a highway where there's one accident that could be avoided, it's going to take 15 times longer after it's removed to get rid of the bottleneck. You'll have a traffic jam all through rush hour just because it was there for 15 minutes.
All of these things affect flow. Accidents are one part, but it's also knowing where vehicles are. Vehicles with these technologies can run very safely very closely together as well, compared to a normal car.
