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.
Roads that are safer for pedestrians and cyclists get more people out of their cars. Longer car commute times make people consider alternatives such as public transit, walking, or biking. Every additional person who isn’t in their car has an exponential decrease in automobile congestion. This is all relatively well understood within urban planning and traffic engineering.

Politics and money quite often make the decision, not sound urban planning.
