  "textContent": "An operation control system includes: a first detector that detects a transport body that has reached a predetermined reference position on a first transport line; an obstacle sensor and an autonomous traveling control unit provided in each of a plurality of self-propelled carrier bodies traveling on a second transport line; a gate provided on the second transport line; and a gate driving unit that moves the gate to a retracted position when the first detector detects the transport body, and moves the gate to an advanced position when the first detector does not detect the transport body. The autonomous traveling control unit controls the travel of the carrier bodies such that a forward separation distance, a distance between any of the carrier bodies and another carrier body or an obstacle ahead of the carrier body, is equal to or greater than a predetermined collision prevention distance.",
