Patent

CA 2106007

A communication system uses simple microwave transmitters disposed along roadways and in-vehicle mounted receivers to transmit encoded signals to produce location-specific commercial, traffic regulatory, emergency and other information to operators of motor vehicles. An optional remote interface links transmitters to regulatory and commercial users in real-time. A microprocessor in the receiver uses the coded signals to produce messages from prerecorded messages or from message parts stored in a replaceable memory device, and to provide the mes- sages either audibly, visually or both. The microprocessor functions under operator supplied instructions to select certain message types for display and to reject unwanted messages. The memory device is recorded in one or more languages to allow the operator to select a preferred lan- guage for message presentation.
