PROBLEM TO BE SOLVED: To highly accurately measure traveling time and traveling distance. SOLUTION: In a navigation device 1 relating to this invention, a CPU 11 displays a beacon selection picture at a display device 18 when an instruction to measure the traveling time and the traveling distance is inputted from an input device 17. Then, when a beacon at the measurement start spot and a beacon at the end spot are selected, the CPU 11 sets the selected beacons as a start beacon and an end beacon. After setting, the CPU 11 starts measurement of the time and the distance at the time of receiving radio waves or light from the start beacon, and ends the measurement of the time and the distance and displays measured results on the display device 18 at the time of receiving the radio waves or the light from the end beacon. |
