Before going out, a user can inquire basic conditions of a certain service area of the expressway through the mobile user side navigation subunit, wherein the basic conditions comprise basic information of catering, rest, accommodation, shopping, entertainment, gas stations, charging piles and parking spaces. The method comprises ordering service, the number of parking spaces for freight transportation or passenger transportation and the like, and the amount of the vacant variable quantity of the parking spaces after a certain time is estimated. When the motor vehicle runs on the expressway and is far away from the nearest service area (for example, more than 5 km) during traveling, the terminal navigation system acquires a message from the navigation center system unit through the operator communication network, and the client terminal receives the distance from the front service area and prompts the information of the parking space. For example, "5 km ahead, service area on right side, please change lanes in advance". When the motor vehicle runs close to the service area (such as 2km), the sensing equipment in the service area sends the parking space information to the navigation center system unit, the information is interacted with the communication message system unit through a chatbot system, the message is sent to the mobile user terminal navigation unit subscribed with the rich media message service through the 5G network, and the basic general pictures of the parking space can be displayed, wherein the basic general pictures of the parking space are reported on the basis of a short message entrance interface (of a terminal rich media message system) or the terminal navigation system, such as 'the service area with 2km in front and 5 empty truck parking spaces'.
