To enable vehicles to travel safely without risk of head-on collision when they have been made to travel on an oncoming lane in order to avoid an obstacle on the original lane. In addition, when travel conditions have been set or changed, it becomes possible to transmit data quickly but a problem of a production efficiency being reduced as a result of all the vehicles being stopped does not arise nor is there a safety problem due to a delay in data changes. On the basis of a monitored result of the travel conditions of the travel track, a no-entry area E is established ahead of a vehicle Jm traveling on one lane of a 2-way dual-lane vehicle track. Then travel instructions are issued to the vehicle Jm, the travel instructions causing it to avoid the no-entry area and travel on a section L of an oncoming lane, a lane whose traffic runs in the opposite direction to the one lane. Travel instructions are issued to an oncoming vehicle Jt traveling on the oncoming lane which prohibits entry to the section L. In addition, an upper limit velocity is set on the section L. Then, travel conditions, including the upper limit velocity set for the section 47, are issued as the travel instructions to the vehicle. When the travel instructions are issued to the vehicle, the vehicle travels on the section 47 at a velocity which does not exceed the upper limit velocity.
A vehicle travel control system in which travel conditions of a travel track made up of 2-way dual-lane vehicle tracks on which a plurality of vehicles travel are monitored by a monitor station, and travel instructions are issued to the plurality of vehicles from the monitor station;
A vehicle travel control system in which travel conditions of a travel track on which a vehicle travels are set by a monitor station and travel instructions corresponding to the travel conditions are issued to the vehicle by the monitor station, comprising
A vehicle travel control system in which travel conditions of a travel track system on which a vehicle travels are changed by a monitor station and travel instructions corresponding to the changed travel conditions are issued to the vehicle from the monitor station;
A vehicle travel control system which is applied to a travel track on which a vehicle slips in accordance with a lateral acceleration applied in a lateral direction relative to a direction of travel of the vehicle, and in which travel conditions for the travel track on which the vehicle is traveling are set by a monitor station and travel instructions corresponding to the travel conditions are issued to the vehicle by the monitor station;
A vehicle travel control system in which travel conditions of a travel track system on which a vehicle travels are set by a monitor station and travel instructions corresponding to the travel conditions are issued to the vehicle by the monitor station, comprising:
