PROBLEM TO BE SOLVED: To provide a vehicle position presentation device that allows a manager to easily check whether or not a vehicle has traveled as scheduled on a travel route to a destination.SOLUTION: When a checking time T is reached, a CPU calculates a decision radius R and sets a circle with a destination on a map as the center (S5). When a vehicle mark representing the current position of a vehicle is on the outside of the circle drawn with the decision radius R, in other words, the vehicle is out of a reachable range, the CPU presents the vehicle mark in red and displays the vehicle mark overlapped on the map on a screen (S11). |
