PPROBLEM TO BE SOLVED: To improve the safety of the driving of a driver. PSOLUTION: Traveling record data generation processing is performed while traveling (100), route information is acquired and a dangerous driving degree is evaluated. Then, when an engine is turned off (102), the travel time is measured (103), and the traveling record data of the same route as the route of the judgement object of this time and the same time zone are retrieved from a traveling record database (106). Then, the retrieved traveling record data and the traveling record data of this time are compared with each other, and when the dangerous driving degree in the traveling of this time is lower than the dangerous driving degree of the retrieved past traveling record data and the travel time of this time is shorter than the upper limit value of a prescribed range including the travel time of the retrieved past traveling record data (110), the driver is advised that the dangerous driving degree of the driving of this time is low compared to the driving in the past and there is not much difference from the past traveling time (112).
