1. A system for vehicle-to-vehicle communication between a first material handling vehicle and a second material handling vehicle, the system comprising:
a first material handling vehicle including a wireless transceiver configured to send and receive vehicle condition data, a speed sensor configured to detect a speed of the material handling vehicle, a steering angle sensor configured to detect a steering angle of a traction wheel, a position sensor configured to detect a position of the material handling vehicle, and a control unit in communication with the wireless transceiver, the speed sensor, the steering angle sensor, and the position sensor, the control unit configured to:
receive a vehicle condition data, via the wireless transceiver, from a second material handling vehicle within a predetermined communication range of the wireless transceiver;
calculate a first predicted vehicle position for the first material handling vehicle based on current vehicle condition data, the first predicted vehicle position comprising a two-dimensional planar area including a plurality of possible positions of the first vehicle at a first time;
calculate a second predicted vehicle position for the second material handling vehicle based on the received vehicle condition data, the second predicted vehicle position comprising a two-dimensional planar area including a plurality of possible positions of the second vehicle at the first time; and
determine if the first predicted vehicle position and the second predicted vehicle position overlap,
upon the determination of an overlap between the first predicted vehicle position and the second predicted vehicle position, activate an operator indicator.
