PROBLEM TO BE SOLVED: To improve the efficiency of a door-to-door sale by providing an optimum route determination means for visiting a person to be visited in an optimum route based on position data and map data, measuring a current position according to an electronic wave for measuring position from an artificial satellite, and moving a traveling body to the optimum route. SOLUTION: A door-to-door sale system has, for example, an antenna 2 for receiving radiowaves for measuring position from an artificial satellite 1, a map data storage part 4, a microcomputer 6, and a display 7. A plurality of position data (for example, an address) of a person to be visited from door to door are inputted. Then, map data of the storage part 4 are read and an optimum route is determined based on a plurality of position data being inputted from an input part 5 and the map data of the storage part 4. Then, radiowaves for measuring position are received from the artificial satellite 1 via the antenna 2 and the current position of the traveling body is measured based on the position measurement data being outputted from a control part 3. Finally, for example, the map data, the optimum route, and the current position of the traveling body are displayed on the display 7. |
