Abstract: A semiconductor integrated circuit device may include first and second delay circuits and a control circuit block connected between the first and second delay circuits. The first and second delay circuits may each include a plurality of delay elements serially connected with each other. The control circuit block may receive an output signal of the first delay circuit. The control circuit block may input an inversion signal, which may be generated by inverting the output signal of the first delay circuit, into the second delay circuit in response to a compensation signal.

Abstract: Provided is a passenger evacuation direction guidance system, and particularly, a passenger evacuation direction guidance system capable of easily evacuating passengers to a safe place from a disaster or an accident occurring during a train service, and including an emergency situation detection unit which determines the occurrence of a disaster or an accident on a traveling route of a train, an evacuation direction generation unit which receives an emergency situation detection signal in respect to the occurrence of a disaster or an accident from the emergency situation detection unit, and generates passenger evacuation direction information at a disaster or accident occurrence point, and an evacuation direction control unit which receives the passenger evacuation direction information generated by the evacuation direction generation unit, and provides a passenger evacuation direction to the passengers.
