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.

There have been a variety of attempts to make light-emitting display sticks, used when directing traffic at night, cheering at various events, and the like, that not only simply emit light but take advantage of persistence of vision to display letters or patterns in space. However, depending on the manner in which and speed at which the stick is waved, said letters or patterns become distorted and unrecognizable. In light of this problem, the issue is to implement a light-emitting display stick that both is suited to cheering at events and can display easily recognizable letters in space regardless of the manner in which and speed at which the stick is waved. The light-emitting display stick in the present invention contains an internal waving-angle sensor and can display undistorted letters or patterns in space by having light-emitting elements emit light in accordance with waving-angle information indicating angles with respect to a base angle. Said light-emitting display stick can also switch to a mode in which all of the light-emitting elements emit light. Said light-emitting display stick is thus easier to use and more effective.
