More specifically, the present invention relates to a method for controlling traffic signals, that is, road signals. More specifically, the present invention relates to a control method for traffic signals, that is, road signals. More specifically, it is a method for providing a seismic motion sensor in or near a tunnel of a motorway. In addition, traffic lights and multiple variable signs and indicators are installed at predetermined intervals from the entrance of the tunnel toward the direction of vehicle arrival. As soon as the above display indicated that an earthquake had occurred, the traffic light was switched from "true" to "red" and the variable sign was controlled to restrict the entry of cars into the tunnel. It is characterized by points.
従来より列車関係では地震感知器か作動した場合9列車
を停止させることか行われているか、道路においてはい
まだ十分に行われていない。Conventionally, trains have been forced to stop nine trains if an earthquake detector is activated, but this has not yet been done sufficiently on roads.
自動車専用道路においては、そのトンネル内に地震感知
器を設け、そしてその感知信号によって信号を制御する
などの工夫かなされていないため。This is because on expressways, there are no measures such as installing earthquake detectors in the tunnels and controlling traffic lights based on the detected signals.
地震の際にも危険なトンネル内を通常の速度で卓か通行
することになりきわめて危険である。This is extremely dangerous as you will have to drive at normal speed through a tunnel that is dangerous even in the event of an earthquake.
この発明はこのような点に着目し1%に地震の除にその
震度か予じめ定めである震度以上の場合には、被害か起
き易いトンネルへの進入を規制するようにしたものであ
る。This invention focuses on this point and is designed to restrict entry into tunnels where damage is likely to occur if the seismic intensity exceeds a predetermined intensity, excluding 1% earthquakes. .
トンネル内、又はトンネル近傍に地震度感知器を設ける

つの信号機と複数の可変標識と地震か発生した場合に、
そnを表示する表示器を設けて、トンネルの入口に向っ
て走行して来る車に対して上記感知器の作動状態に基い
て上記の表示器と信号機と標識によって指示を出すよう
にした。In addition to installing an earthquake intensity sensor in or near the tunnel, a traffic light and multiple variable signs are installed from the entrance of the tunnel toward the direction of vehicle arrival, in the event of an earthquake.
A display device is provided to display this, and instructions are given to vehicles traveling toward the tunnel entrance using the display, traffic light, and sign based on the operating state of the sensor.
地震動か検知され、それか予じめ定めである震度以上の

ろで停止させる。If an earthquake is detected and the seismic intensity exceeds a predetermined intensity, the display will indicate that an earthquake has occurred and will flash, and the variable signs will also change their markings and flash, and the traffic lights will turn green. The driver then changes the light to "red" and drives toward the tunnel entrance, gradually reducing the speed of the vehicle until it stops at the traffic light.

For example, it is marked as 1) 00k/h). In such a state, when an earthquake occurs, the controller 14+ is given an IC sensing signal from the sensor (3), and if the degree is greater than a predetermined value, the controller 14+ outputs a control signal (10b) and displays the 1 indicator section.

置Q4に位置する。Figure 2 shows an example of the structure of a sign, where αυ is a dot (13), which is the minimum unit of display characters, etc. am is a round rod-shaped light guide in which one or more dots are formed, and is made of transparent plastic, has flexibility, and is made to correspond to each transparent or translucent dot α2. .The dot (I3) is the minimum unit of a character symbol or figure (picture) to be described later. One end of the light guide is connected to the front plate (

通常の速度標示より低い速度標示を行う。Therefore, the controller (41) outputs a control signal to change the speed indicator according to the speed of the vehicle traveling in the event of a landslide of a predetermined seismic intensity.In other words, the selection circuit 0 selects the original switch 1.
Display speed signs lower than normal speed signs.
そのため標識(71+81にそれぞn走行して来る車を
信号機+51の手前で停止させるべく制動距離を考慮し

とになり、それによって事故を防ぐことかできる。This invention is configured as described above, so if an earthquake is detected and the motion is more than a predetermined straightness, the driver is first informed of the occurrence of an earthquake by displaying the occurrence of an earthquake on the display, and then the driver is driven towards the entrance of the tunnel. The speed of the incoming vehicle will be gradually reduced according to the instructions of the sign, and the vehicle will be stopped before the tunnel entrance, thereby preventing accidents.

バにおきかえてもよいことは言うまでもない。Incidentally, in the above embodiment, a round rod-shaped light guide made of transparent plastic was used as an example, but it goes without saying that this may be replaced with an optical fiber.
また、地′IM度センサはトンネル内に設けられている
