Abstract: Electronic equipment in vehicles may transmit and receive wireless messages. Each wireless message that is transmitted by a transmitter may include information on the vehicle from which it is being transmitted, information on the location of the transmitter within the vehicle, and other vehicle status information. Receiving equipment in vehicles may be used to receive the transmitted messages. Received signal strength indicator information may be associated with the transmitted messages. Using the received signal strength indicator information and information on the locations of the transmitters within the vehicles in which the transmitters are installed, equipment in a receiving vehicle may determine locations for nearby vehicles. Alerts may be presented to a driver of a vehicle and other suitable actions may be taken based on the locations of nearby vehicles, vehicle type information, and other information regarding traffic in the vicinity of the driver.

Abstract: Electronic equipment in a system may transmit and receive wireless advertisement messages. Each wireless message may include location information and may have an associated received signal strength indicator when received from transmitting equipment by receiving equipment. The transmitting equipment may be associated with stationary equipment such as equipment installed at a building, adjacent to a road, or in traffic control equipment or other traffic structures. The receiving electronic equipment may be mobile equipment such as a vehicle or mobile computing equipment such as a cellular telephone or portable computer. Satellite navigation system signals may be received by the receiving electronic equipment in addition to the wireless messages. The receiving electronic information can present alerts to a user based on a location determined using the wireless messages and the satellite navigation system signals.
