[Challenge] Fleet management system with intersections targeted vehicles advance service route bus, etc. are determined non-stop running control function. A Path information of the vehicle to perform the operation control, the intersections the vehicle path center apparatus having various information required for the driving condition calculation for passing a green light-non-disruptive, and the in-vehicle device having a vehicle location function, the Configure the system, The center device, to obtain a specific point (for example, an intersection, etc.) passing information from the vehicle device, passing through the intersection to be passed to the next in which the vehicle is next identification and the specific intersection should pass through a green light-nondisruptively The report to the vehicle and to the vehicle to calculate the driving condition to begin the running of the intersection to be passed in the next driving condition that is the notification, After the vehicle starts the traveling, the center apparatus is reported to each time the vehicle is carried out the calculation of the specific point elapsed time after the passage information and travel distance information is obtained by modifying driving conditions of the vehicle device every predetermined time the vehicle is traveling while sequentially updating the traveling conditions in the notification has been modified driving conditions passing through the intersection on a green light, non-stop.
