This invention enables freeways to carry the maximum amount of traffic they can safely carry during times of heavy use of the freeway system. The invention would maximize freeway capacity by restricting the inflows of traffic and facilitating the exits from the freeway. Freeway inflows would be restricted by extensive use of metering lights and restrictions on speeds on the freeway itself. Freeway exits would be facilitated by changing traffic lights, stop signs, and anything else that restricts exits from a freeway, to allow for the free flow of traffic off a freeway. An optimized freeway system would shorten commutes, lessen consumption of gas, lower pollution, and lessen the need to build or expand freeways. Thus, it would save several billions of dollars every year.
