A data collection system includes: a communication terminal in each vehicle having a storage processor storing specific sensing information in a storage device and a vehicle-side communication unit; and a data center including a data center-side communication unit and a data center-side storage. The vehicle-side communication unit sequentially transmits vehicle information including a vehicle position to the data center. The data center-side communication unit transmits a transmission request of object information as the specific sensing information to an object vehicle, which is one of the vehicles approximately at a traveling position specified based on the vehicle position. The vehicle-side communication unit transmits the object information to the data center. When the data center-side communication unit receives the object information from a part of object vehicles, the data center-side communication unit transmits a deletion request for requesting to delete the object information to a remaining part of the object vehicles.
