1. A system for determining a position of a first vehicle during movement of the first vehicle, comprising:

  • an information communication system configured to be transported by the first vehicle, the information communication system being operable to receive from at least one second vehicle an estimate of a position of the at least one second vehicle in relation to the first vehicle during movement of the first vehicle and the at least one second vehicle; and

    a position determining system configured to be transported by the first vehicle, the position determining system having (i) a plurality of sensors operable to obtain information relating to positions of each of a plurality of third vehicles and non-moving objects in a vicinity of the first vehicle during movement of the first and third vehicles, and (ii) a processor operable to determine a first estimate of a position of the first vehicle in relation to the third vehicles and non-moving objects from the information obtained by the plurality of sensors and from the received estimate of the position of the at least one second vehicle,wherein the sensors include a plurality of electronic cameras and the position determining system is operable to determine a displacement between the first vehicle and the plurality of third vehicles through processing of stereoscopic imaging obtained from the electronic cameras.
