Systems and methods for on-ground vehicle collision avoidance utilizing shared vehicle hazard sensor data are provided. In one embodiment, a system comprises: a ground based hazard data aggregation system comprising at least one memory storing a hazard position database; and at least one vehicle-ground communications electronics system coupled to the aggregation system; wherein the aggregation system is communicatively coupled to an onboard ground hazard collision avoidance system of at least a first on-ground subscriber vehicle through a wireless datalink established via the vehicle-ground communications electronics system; wherein the hazard position database stores vehicle collected hazard position data generated by a first on-ground contributing vehicle; and wherein the ground based hazard data aggregation system transmits to the first on-ground subscriber vehicle aggregated hazard position data from the hazard position database, the aggregated hazard position data including the vehicle collected hazard position data generated by the first on-ground contributing vehicle.
