Abstract: A driving assistance method of assisting driving of a vehicle, includes, by a computer, acquiring biological information of a driver who is driving the vehicle, acquiring environment information of the driver, acquiring operation information of the driver, generating biological index data from the biological information, generating integrated information by aligning and combining time series of the biological index data, the environment information, and the operation information, calculating accident risk information after a predetermined time, by inputting the integrated information to an accident risk prediction model set in advance, and calculating factor information of the accident risk information by inputting the accident risk information, the integrated information, and accident risk judge information set in advance to a factor calculation model set in advance.

Abstract: An operation management aid system can access a first group of associated data in which biological measurement data pertaining to a biology of a driver is associated with task state data pertaining to a task state of the driver, and a second group of danger determination results indicating a degree of danger of driving by the driver, and wherein a processor executes: acquiring, the associated data pertaining to a specific task state of the driver from the first group, and acquiring a specific danger determination result group in the specific task state of the driver from the second group; and using an associated data group pertaining to the specific task state and a specific danger determination result group for the specific task state, to generate, for each of the specific task states, an estimation model that estimates an accident risk of the driver during the specific task state.
