Abstract
A spread spectrum code division multiple access communication system has a plurality of traffic channels. A plurality of traffic lights have a red state and a green state. Each traffic light is associated with a traffic channel. The state of each traffic light is based on an availability of that traffic light's associated traffic channel. The base station broadcasts each traffic light over a broadcast channel.
