an another-lane travel permitting section that sets, as a travel-permitted zone of another-lane with a travel permission given to the manned vehicle only, a zone located on a lane adjacent to the lane, on which the manned vehicle is traveling, and including at least a part of a zone arranged side by side with the first travel-permitted zone, and

a controller-side communication control section that transmits, to the manned vehicle, information indicating positions of the travel-permitted zone and the travel-permitted zone of another-lane; and

the manned vehicle comprising:

a command input accepting section that accepts an operation which makes a setting request for the travel-permitted zone of another-lane on the lane adjacent the lane on which the manned vehicle is traveling,

a display control section that displays the travel-permitted zone of another-lane on a screen,

a terminal-side communication control section that to and from the traffic control device, transmits the setting request and receives the information indicating the position of the travel-permitted zone of another-lane, respectively,

wherein the command input accepting section additionally accepts an operation with makes a cancellation request for the travel-permitted zone of another-lane, and

wherein the another-lane travel permitting section cancels, in response to the cancellation request, the setting of the travel-permitted zone of another-lane if the manned vehicle has a body included in the first travel-permitted zone and is in a direction matching a travelling direction of the first travel-permitted zone or if the manned vehicle has a body included in the travel-permitted zone of another-lane and is in a direction matching a traveling direction of the travel-permitted zone of another-lane.

2. The traffic control system according to claim 1 , wherein:

the travel-permitted zone setting section additionally sets, in one of the plural lanes on which one lane an autonomous traveling vehicle is autonomously traveling, a second travel-permitted zone, for which a travel permission is given to the autonomous traveling vehicle only, at a zone where the first travel-permitted zone or the travel-permitted zone of another-lane has not been set.

3. The traffic control system according to claim 1 , wherein:

following setting of a new first travel-permitted zone for the manned vehicle by the travel-permitted zone setting section, the another-lane travel permitting section sets a new travel-permitted zone of another-lane at a zone arranged side by side with the new first travel-permitted zone.

4. The traffic control system according to claim 1 , wherein:

the travel-permitted zone of another-lane is a zone including a zone that is arranged on the adjacent lane side by side with the first travel-permitted zone.

5. The traffic control system according to claim 1 , wherein:

the traffic control device further comprises a passing path generation section that generates a passing path, which allows the manned vehicle to avoid a front obstacle, on the lane adjacent the lane on which the manned vehicle is traveling, and

the passing path generation section generates the passing path in the travel-permitted zone of another-lane set for the manned vehicle.

6. A traffic control device that performs traffic control of a manned vehicle traveling according to operation by an operator on one of plural lanes arranged side by side in a mine, comprising:

a travel-permitted zone setting section that sets a zone of the lane, on which the manned vehicle is traveling, as a first travel-permitted zone with a travel permission given to the manned vehicle only,

an another-lane travel permitting section that sets, as a travel-permitted zone of another-lane with a travel permission given to the manned vehicle only, a zone located on a lane adjacent to the lane, on which the manned vehicle is traveling, and including at least a part of a zone arranged side by side with the first travel-permitted zone, and

a controller-side communication control section that transmits, to the manned vehicle, information indicating positions of the travel-permitted zone and the travel-permitted zone of another-lane,

wherein the another-lane travel permitting section cancels the setting of the travel-permitted zone of another-lane if the manned vehicle has a body included in the first travel-permitted zone and is in a direction matching a travelling direction of the first travel-permitted zone or if the manned vehicle has a body included in the travel-permitted zone of another-lane and is in a direction matching a traveling direction of the travel-permitted zone of another-lane.

7. An on-board terminal device to be mounted in a manned vehicle that travels according to operation by an operator on one of plural lanes arranged side by side in a mine, comprising:

a command input accepting section that accepts operation which makes a setting request for a travel-permitted zone of another-lane, with a travel permission being given to only an own vehicle with the on-board terminal device mounted therein, on a lane adjacent the lane on which the own vehicle is traveling,

a display control section that displays a position of the travel-permitted zone of another-lane,

a terminal-side communication control section that to and from a traffic control device which performs traffic control for the manned vehicle, transmits the setting request and receives information indicating the position of the travel-permitted zone of another-lane, respectively; and

a terminal-side map information storage section that stores map information defining positions of the plural lanes and traveling directions of the respective lanes,

wherein, if an operation performed on the command input accepting section to cancel the setting of the already-set travel-permitted zone of another-lane when the traffic control device has set a zone of the lane, on which the manned vehicle is traveling, as a travel-permitted zone with a travel permission given to the manned vehicle only, and if the terminal-side communication control section has received the information indicating the position of the travel-permitted zone, the command input accepting section acquires a position of the own vehicle from a position calculating device mounted on the own vehicle, refers to the position of the own vehicle and the map information, and accepts a cancellation request operation to cancel the setting of the travel-permitted zone of another-lane if the own vehicle has a body included in the travel-permitted zone and the body of the own vehicle is in a direction matching a traveling direction of the travel-permitted zone or if the body of the own vehicle is included in the travel-permitted zone of another-lane and the direction of the body of the own vehicle matches a traveling direction of the travel-permitted zone of another-lane.

8. The on-board terminal device according to claim 7 , wherein:

upon acceptance of operation for selection of desired two points with the adjacent lane interposed between the two points, the command input accepting section generates a rectangular area including the two points as diagonally opposite vertices thereof and extracts a zone on the another lane, which zone is included in the rectangular area, as an acquisition request zone in which a request is made for acquisition as the travel-permitted zone of another-lane, or designates desired two segments on the another lane and extracts a series of segments, which include the desired two segments, as the acquisition request zone.

9. The on-board terminal device according to claim 7 , wherein:

if the own vehicle changes in position in association with traveling of the own vehicle, the command input accepting section additionally accepts operation for requesting resetting of the travel-permitted zone of another-lane following the change in the position of the own vehicle.

10. The on-board terminal device according to claim 7 , wherein:

the plural lanes comprise at least three lanes, and

the command input accepting section additionally accepts operation that designates on which one of left and right lanes relative to a traveling direction of the own vehicle the travel-permitted zone of another-lane is to be set, and also input operation of the number of one or more lanes where the travel-permitted zone of another-lane is to be set.
