A vehicle operation management system including a vehicle-mounted device, an operation management server, a site management device, and a network connecting them is disclosed. This vehicle-mounted device can automatically transmit the vehicle position information acquired by the GPS function to the operation management server periodically via the network. The operation management server stores shipping position information, which is information on a raw control factory where raw control goods are loaded on each agitator vehicle, and virtual gate information, which is position information of a virtual gate that is separated from the raw control factory by a predetermined distance. Based on the position information of each agitator vehicle acquired from the vehicle mounting device and the virtual gate information, the time when each agitator vehicle passed the virtual gate is acquired, and this time and the travel time of the vehicle from the virtual gate to the ready control factory Can be predicted based on the set time set in advance, and the estimated arrival time at which each empty agitator vehicle not loaded with ready-mixed food arrives at the ready-mixed factory.

JP 2003-346295 A Japanese Patent No. 4889031

  According to the systems described in Patent Documents 1 and 2, the actual position of the agitator vehicle can be grasped on the map displayed on the display unit of the management device provided in the management office. Because the management is based on the dynamics, location, and route information of the vehicle, the real-time situation of the road on which it actually travels is unknown, and it is not possible to comply with the promised time with the delivery site due to traffic jams, road regulations, etc. Had occurred.

  In order to prevent the occurrence of such inconvenience, conventional vehicle management systems have routinely performed operation management to avoid delays in delivery by advancing the departure time of the agitator vehicle from the ready-mix factory. . However, if there is an excessive amount of time, the arrival time will be earlier than the promised delivery time, resulting in an increase in standby time at the site. Since it is essential for the agitator vehicles to arrive without interruption in order to prevent joints from occurring, there is a problem that the number of waiting vehicles increases more than necessary, causing congestion around the site.

  If the waiting time increases, the non-operating time of the agitator car will increase, leading to a reduction in operating efficiency, and even if the agitator car is on standby, the engine can not be turned off to prevent the batch of raw concrete. Problems such as an increase in fuel costs and an increase in carbon dioxide generation have also occurred.
