Claim 15:
16. A vehicle comprising:
a chassis;
a plurality of sides, the plurality of sides being supported on the chassis, the plurality of sides including at least a first side and a second side;
a microphone array, the microphone array including a plurality of microphones mounted on the plurality of sides, the microphone array configured to capture at least one signal from a source external to the vehicle, wherein the microphone array includes a first plurality of microphones and a second plurality of microphones, the first plurality of microphones being mounted on the first side and the second plurality of microphones being mounted on the second side;
a processor, the processor carried on the chassis; and
logic, when executed by the processor, operable to process the at least one signal captured by the microphone array to determine at least one direction from which the at least one signal originates, wherein the logic operable to process the at least one signal includes logic operable to
i) determine a first intensity difference based on the at least one signal across the first plurality of microphones at a first time,
ii) determine a second intensity difference based on the at least one signal across the second plurality of microphones at the first time,
iii) determine a third intensity difference based on the at least one signal across the first plurality of microphones at a second time,
iv) determine a fourth intensity difference based on the at least one signal across the second plurality of microphones at the second time,
v) estimate at least one of a speed of travel and a direction of travel of the source based on the first intensity difference, the second intensity difference, the third intensity difference, and the fourth intensity difference, and
vi) predict at least one of a time and a destination at which the vehicle and the source are expected to cross paths based on the at least one of the speed of travel and the direction of travel.
