The second route planning result passes through the substituted road section, and the candidate road section is excluded from the second route planning result.

Abstract: A transporting device has a container, a panel member, a wheel frame and two wheels. The panel member has a plate and two first linkages pivoted on the plate and on lateral sides of the container respectively. The wheel frame has two second linkages pivoted on mid sections of the first linkages respectively and the wheels are mounted on the second linkages. The panel member is moved between a collapsed position, in which the plate is attached on the container and the wheels are moved to the lateral sides of the container respectively, and an expanded position, in which the plate and the wheels are moved apart from the container. The container is provided with a shaft with a handle and a front wheel on opposite ends to control the direction of the transporting device to go. A motor and a transmission device are provided to drive the transporting device to run.
