Description

  The present invention relates to a traffic signal control system, and more particularly to a traffic signal control system capable of ensuring the safety of a pedestrian even when a signal lamp is controlled based on a plurality of step signals.

  In general, in the current control of road traffic signals in Japan, a step control method is adopted in which a signal lamp is switched for each step based on a step signal output at a predetermined pitch from a step signal generator. This step control method can be said to be a very excellent method in terms of safety since the change of the step signal is performed serially in units of steps.

  However, in the conventional step control method, there is only one type of step counter that counts the number of seconds of each step, and there is a problem that uplink and downlink cannot be controlled separately.

  Therefore, conventionally, for example, a control means for generating a step signal for switching the operation of the signal lamp every step, and a signal control circuit for switching the operation of the signal lamp based on the step signal generated by the control means, A display memory for storing the lamp color data for lighting the signal lamp corresponding to the step signal, and the signal control circuit counts the step signal generated from the control means by the step counting means. A technique is disclosed in which the lamp color data stored in the display memory is read based on the number of steps and the signal lamp is turned on (see, for example, Patent Document 1).

  However, in the technique described in Patent Document 1, when the signal lamp for a vehicle signal is controlled based on a plurality of step signals, the signal lamps for the straight direction and the left turn direction of the vehicle signal are for the upward lane. The lighting state of the signal lamp and the signal lamp for the downward lane may be shifted. Conventionally, since the signal lamp for the vehicle signal and the signal lamp for the pedestrian signal are separately controlled, the lighting state of the signal lamp for the pedestrian signal is the same as that of the signal lamp for the vehicle signal. There is a problem that it may deviate from the lighting state and there is a possibility that the safety of the pedestrian cannot be ensured.

By shifting from step 1 to step 4 in the N direction in this way, the N1 direction vehicle 1 and the N2 direction vehicle 5 are stopped, and pedestrians cannot cross.

  In this state, since the vehicle is continuously controlled by step 1 in the S direction and controlled by step 4 in the N direction, the S1 direction vehicle 3 can go straight, turn left, and turn right. At this time, since the traffic light 17 (1P) for the N1 direction pedestrian is red, the pedestrian cannot cross, but the traffic light 18 (2P) for the S1 direction pedestrian is blue. Is traversable.

  Thus, in this embodiment, for example, when the pedestrian detection device 21 detects that the amount of pedestrian crossing in the S1 direction pedestrian traffic light 18 is large, the S1 direction pedestrian traffic light 18 ( 2P) is held in blue, and when the S1 direction vehicle straight / left turn signal 10 (2G) and S1 direction vehicle right turn signal 14 (2A) are controlled in blue, the N1 direction pedestrian traffic light 17 ( Since 1P) is controlled to be red, the right turn of the S1 direction vehicle and the pedestrian crossing by the N1 direction pedestrian traffic light 17 (1P) do not cross each other.

  As described above, in the present embodiment, when the vehicle is controlled so that it can go straight or turn left, the pedestrian signal lamp 24 is controlled to be blue, and the vehicle is controlled so that the vehicle can turn right using the vehicle signal lamp 23. In this case, since the pedestrian signal lamp 24 installed on the right turn side of the vehicle is always controlled to be red, the vehicle signal lamp 23 and the pedestrian signal lamp 24 are controlled based on a plurality of step signals. Even when the pedestrian signal lamp 24 is controlled, it is possible to reliably prevent the lighting state of the pedestrian signal lamp 24 from deviating from the lighting state of the vehicle signal lamp 23. As a result, the safety of the pedestrian is ensured. be able to.

  In the above-described embodiment, an example in which the vehicle goes straight and turns left and the pedestrian's crossing installed on the right turn side of the vehicle is not crossed, but the vehicle goes straight and turns right, You may make it apply when it is made not to cross with the crossing of the pedestrian installed in the left turn side of a vehicle.
