Abstract
The data communication device and method include storing road map information indicating locations of nodes and links, a time when a vehicle enters one link and an identifier of the link, and a vehicle location and the link identifier in a memory, periodically acquiring vehicle position data, identifying the link based on the road map information, and comparing the identified link with the link the vehicle has passed through a node. The device rewrites the position data and acquired time stored in the memory when receiving a result that the vehicle has not passed, determines an exit time based on the acquired time and the time of last acquired position data when receiving a result that the vehicle has passed, calculates a travel period of the vehicle, writes the exit time as an entry time, rewrites the link identification data, and transmits the travel period to a given communication destination.
