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.

A signal transmission method checks, when detecting an occurrence of a communication request, whether the communication request is a high speed communication (step S302). In the case of the high speed communication, it checks whether the number of current high speed communications (m) plus one is greater than the upper limit (mmax) of the high speed communication (step S312). If greater, it cancels the request as a call loss (S316), and sets to a variable a the ratio (h) of the rate of the high speed communication to that of a low speed communication. If the communication request is the low speed communication, it sets one to the variable a (step S304). It compares n plus a with nmax (step S306), where n is the total number of all the current communications, a is the value associated with the communication request, and nmax is the upper limit of the number of communications acceptable in a bandwidth, all of which are expressed in terms of the number of the low speed communications. If n plus a is greater than nmax, the communication request is canceled as a call loss (S316). Otherwise, the total number of the current high speed communications (m) and the total number of all the current communications (n) expressed in terms of the number of the low speed communications are updated, and a channel is assigned to the communication request (step S310).
