Methods for vehicle to vehicle communication, vehicle detection, and vehicle to traffic sign communication are devised. Such methods can involve the use of one or a plurality of speakers to emit artificial sound signals, as well as the use of one or a plurality of sound detectors to record artificial or natural sound signals emitted by nearby vehicles or traffic signs. The use of an active sonar system will also allow autonomous vehicles to detect nearby surroundings. The Doppler Effect can also be used to determine the speeds of moving vehicles. These methods allow autonomous vehicles to drive and respond to their surroundings, and also allow traffic signs to respond to various traffic situations by detecting the presence of nearby vehicles.
