Google has shared an update about its AI-driven mission to reduce wait times, fuel use, and polluting emissions at intersections – and the early indications are that stops can be reduced by around 30 percent, with emissions dropping around 10 percent.
Ever heard of roundabouts?
Roundabouts are amazing, but they have 2 drawbacks. Throughput is limited and the size of the intersection becomes larger. Hence, there will always be a lot of places where traffic lights are the better option.
Road designers say if you want traffic throughput in high traffic situations, use traffic lights instead of roundabouts. Apparently there are a lot of studies that show that.
