Description

本発明は、夜間に信号機設備のない横断歩道に向かって走行中の車両のドライバーに対して横断歩道を横断中の歩行者又は自転車等の存在を認識させる交通安全システムに関する。   The present invention relates to a traffic safety system that allows a driver of a vehicle traveling toward a pedestrian crossing without traffic light equipment to recognize the presence of a pedestrian or a bicycle crossing the pedestrian crossing at night.

夜間に信号機設備のない横断歩道における歩行者又は自転車等と車両との衝突事故を防止するための技術として、横断歩道に沿って路面に埋設した複数の発光式道路鋲を歩行者又は自転車等の横断時に横断歩道に向かつて走行中の車両に発光させて、ドライバーに注意を喚起させる交通安全システム（例えば特許文献１）がある。   As a technique to prevent collisions between pedestrians or bicycles and vehicles in a pedestrian crossing without traffic light equipment at night, multiple light-emitting road fences embedded on the road surface along the pedestrian crossing are used for pedestrians or bicycles. There is a traffic safety system (for example, Patent Document 1) that alerts a driver by emitting light to a traveling vehicle toward a pedestrian crossing when crossing.

特開平１１−２０９９２９号公報JP-A-11-209929

しかしながら、発光式道路鋲から発光する光が車両に向けて出ているものであるため、実際に横断歩道を横断している歩行者等の存在自体を十分にドライバーに認識することが困難であった。   However, since the light emitted from the light-emitting road fence is emitted toward the vehicle, it is difficult for the driver to fully recognize the presence of pedestrians who actually cross the pedestrian crossing. It was.

本発明は、上記のような問題を解決するためになされたものであり、横断歩道に向かって走行中の車両のドライバーが横断歩道を横断している歩行者等の存在を確実に認識できる交通安全システムを提供せんとするものである。   The present invention has been made to solve the above-described problems, and traffic in which a driver of a vehicle traveling toward a pedestrian crossing can reliably recognize the presence of a pedestrian or the like crossing the pedestrian crossing. It is intended to provide a safety system.

上記目的を達成するため、本発明は、横断歩道を横断しようとする歩行者又は自転車を検知する検知センサーと、横断歩道に近接して路面に設置され、前記検知センサーが歩行者又は自転車を検知すると、横断歩道を横断している歩行者又は自転車に向けて発光する発光手段とを備えたことを特徴とするものである。   In order to achieve the above object, the present invention provides a detection sensor for detecting a pedestrian or a bicycle who wants to cross a pedestrian crossing and a detection sensor installed on a road surface in the vicinity of the pedestrian crossing, and the detection sensor detects a pedestrian or a bicycle. Then, a light emitting means for emitting light toward a pedestrian or bicycle crossing the pedestrian crossing is provided.

この発明によれば、横断歩道を歩行者又は自転車（以下、歩行者等と言う。）が横断しようとすると、検知センサーが歩行者等の存在を検知し、発光手段が検知センサーの検知信号により横断歩道を横断している歩行者等に向けて発光される。即ち、横断歩道に近接して路面に設置された発光手段が横断歩道を横断している歩行者等に向けて発光されるため、発光手段から発光された光が横断歩道を横断している歩行者等をライトアップして浮かび上がらせるので、横断歩道に向かって走行中の車両のドライバーに横断歩道を横断している歩行者等がはっきりと見えるようになり、ドライバーは横断歩道を実際に横断している歩行者等の存在を極めて容易に認識することができる。   According to this invention, when a pedestrian or a bicycle (hereinafter referred to as a pedestrian or the like) crosses a pedestrian crossing, the detection sensor detects the presence of the pedestrian or the like, and the light emitting means detects the detection signal of the detection sensor. Light is emitted toward pedestrians crossing the pedestrian crossing. That is, since the light emitting means installed on the road surface in the vicinity of the pedestrian crossing emits light toward a pedestrian or the like crossing the pedestrian crossing, the light emitted from the light emitting means crosses the pedestrian crossing. The pedestrians crossing the pedestrian crossing are clearly visible to the driver of the vehicle traveling toward the pedestrian crossing, and the driver actually crosses the pedestrian crossing. The presence of a pedestrian or the like can be recognized very easily.

また、本発明は、発光手段は、路面に埋設される発光式道路鋲であることが好ましい。これにより、横断歩道を横断している歩行者等を車両の走行を妨げずに照らすことが可能であり、横断歩道付近の交通の邪魔とはならない。   In the present invention, it is preferable that the light emitting means is a light-emitting road fence buried in the road surface. As a result, it is possible to illuminate pedestrians and the like crossing the pedestrian crossing without disturbing the traveling of the vehicle, and it does not interfere with traffic near the pedestrian crossing.

また、本発明は、発光式道路鋲の発光輝度が１０００〜１００００ｃｄ／ｍ2であることが好ましい。これにより、横断歩道を横断している歩行者等を高輝度で照らすことができ、ドライバーに横断歩道を横断している歩行者等がはっきり見えて認識し易い。 Moreover, it is preferable that the light emission brightness | luminance of this invention is 1000-10000 cd / m < 2 >. As a result, pedestrians crossing the pedestrian crossing can be illuminated with high brightness, and the pedestrians crossing the pedestrian crossing can be clearly seen and recognized.

更に、本発明は、発光式道路鋲は、路面に対して２０°〜６０°の角度を持たせて斜め上方に向けて発光することが好ましい。これにより、横断歩道を横断している歩行者等のある程度の範囲を照らすことができ、ドライバーに横断歩道を横断している歩行者等の略全てが見えて認識し易い。   Furthermore, in the present invention, it is preferable that the light-emitting road fence emits light obliquely upward with an angle of 20 ° to 60 ° with respect to the road surface. Thereby, a certain range of pedestrians crossing the pedestrian crossing can be illuminated, and almost all pedestrians crossing the pedestrian crossing can be easily seen and recognized.

本発明によれば、横断歩道を横断しようとする歩行者等の横断時に、横断歩道に近接して路面に設置された発光手段が横断歩道を横断している歩行者等に向けて発光されるため、発光手段から発光された光が横断歩道を横断している歩行者等をライトアップして浮かび上がらせ、これにより横断歩道に向かって走行中の車両のドライバーは横断歩道を実際に横断している歩行者等の存在を極めて容易に認識し得るので、ドライバーは横断歩道を横断している歩行者等の存在に強く注意が喚起され、効果的に横断歩道における歩行者等と車両との事故防止を図ることができる。   According to the present invention, when a pedestrian or the like who wants to cross a pedestrian crossing crosses, the light emitting means installed on the road surface in the vicinity of the pedestrian crossing emits light toward the pedestrian or the like crossing the pedestrian crossing. Therefore, the light emitted from the light emitting means illuminates pedestrians crossing the pedestrian crossing, so that the driver of the vehicle traveling toward the pedestrian crossing actually crosses the pedestrian crossing. The presence of such pedestrians can be recognized very easily, so the driver is strongly cautioned about the presence of pedestrians crossing the pedestrian crossing, effectively causing accidents between pedestrians and vehicles on the pedestrian crossing. Prevention can be achieved.

以下、本発明の実施形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、交通安全装置の全体的な構成を示した配置図である。図１において、１は道路、２は道路１に設けられた横断歩道であり、通常はゼブラ模様が白の塗料で描かれている。   FIG. 1 is a layout diagram showing the overall configuration of the traffic safety device. In FIG. 1, 1 is a road, 2 is a pedestrian crossing provided on the road 1, and a zebra pattern is usually drawn with white paint.

３は横断歩道２に近接して道路１の両側に対角になるように夫々設置された道路標識であり、支柱３１に表示板３２が取り付けられている。   Reference numeral 3 denotes a road sign that is installed near the pedestrian crossing 2 so as to be diagonal on both sides of the road 1, and a display board 32 is attached to the column 31.

４は夜間に横断歩道２を横断しようとする歩行者等を検知する検知センサーであり、道路標識３の支柱３１に横断歩道２の所定の検知エリアＡに向けて取り付けられている。検知センサー４は、横断歩道２の所定の検知エリアＡ内に横断歩道２を横断しようとする歩行者等が存在すれば、その存在を検知して検知信号を送信する。検知センサー４は、特に種類は限定しないが、歩行者等が発する熱（赤外線）を検出する熱（焦熱）センサー、光りを送信して歩行者等にあたり反射して帰ってくる光りを受光する光りセンサー、マイクロ波を送信して歩行者等にあたり反射して帰ってくるマイクロ波を受信するマイクロ波センサー等を使用する。   Reference numeral 4 denotes a detection sensor that detects a pedestrian or the like who wants to cross the pedestrian crossing 2 at night, and is attached to a support 31 of the road sign 3 toward a predetermined detection area A of the pedestrian crossing 2. If there is a pedestrian or the like who wants to cross the pedestrian crossing 2 within a predetermined detection area A of the pedestrian crossing 2, the detection sensor 4 detects the presence and transmits a detection signal. The detection sensor 4 is not particularly limited in type, but is a heat (pyrothermal) sensor that detects heat (infrared rays) emitted by pedestrians, etc., light that transmits light and receives light that is reflected back to pedestrians and the like. A sensor or a microwave sensor that transmits microwaves and receives microwaves that are reflected back to pedestrians and the like is used.

５は横断歩道２を横断している歩行者等に向けて発光する発光式道路鋲であり、横断歩道２の両側に近接して該横断歩道２に沿って道路１に複数埋設され、検知センサー４からの検知信号を伝達すると所定時間発光する。発光式道路鋲５を発光させる時間は、歩行者等が横断歩道を横断するのに充分な時間とする必要があり、通常は３０秒前後であり、その後は自動的に消灯する。   Reference numeral 5 denotes a light-emitting road fence that emits light toward a pedestrian crossing the pedestrian crossing 2, and a plurality of sensors are embedded in the road 1 along the pedestrian crossing 2 in close proximity to both sides of the pedestrian crossing 2. When the detection signal from 4 is transmitted, light is emitted for a predetermined time. The time for which the light-emitting road fence 5 is allowed to emit light needs to be sufficient for a pedestrian or the like to cross the pedestrian crossing, and is usually around 30 seconds, and then automatically turns off.

発光式道路鋲５は、その発光範囲が横断歩道２側に限定されており、１ｍ離れた地点を隙間なく照らすことが可能な間隔をあけて設置されている。この発光式道路鋲５の設置間隔は、発光式道路鋲５の発光範囲の平面角度に応じて設定されており、例えば、発光式道路鋲５の発光範囲の平面角度が６０°であれば、発光式道路鋲５を１．７ｍ間隔に設置する。   The light emitting road fence 5 has a light emitting range limited to the side of the pedestrian crossing 2 and is installed at an interval that can illuminate a point 1 m away without any gap. The installation interval of the light-emitting road fence 5 is set according to the plane angle of the light emission range of the light-emitting road fence 5. For example, if the plane angle of the light emission range of the light-emitting road fence 5 is 60 °, Light-emitting road fences 5 will be installed at 1.7m intervals.

図２は、発光式道路鋲５を示す説明図である。発光式道路鋲５は、道路１に埋設され、上方が開口する本体５１と、本体５１の開口部を閉塞する透光性のカバー材５２と、発光する光がカバー材５２を透過するように発光基台５３ａに取り付けられてカバー材５２の下方に設けられた発光体５３とを備えている。カバー材５２及び発光体５３は、ユニット駆体５４を介して本体５１に取り付けられている。ユニット駆体５４は、発光体５３が収納され、カバー材５２が嵌着される凹部５４ａと、凹部５４ａの周辺に設けられ、本体５１への取り付けに用いられる縁部５４ｂとを有する。ユニット駆体５４に対してカバー材５２は凹部５４ａにボルト止めされ、ユニット駆体５４は本体５１に対して縁部５４ｂがボルト止めされて固定されている。   FIG. 2 is an explanatory diagram showing the light-emitting road fence 5. The light-emitting road fence 5 is embedded in the road 1, and a main body 51 that opens upward, a translucent cover material 52 that closes the opening of the main body 51, and light that transmits light pass through the cover material 52. A light-emitting body 53 attached to the light-emitting base 53 a and provided below the cover member 52. The cover material 52 and the light emitter 53 are attached to the main body 51 via the unit driver 54. The unit driver 54 includes a recess 54 a in which the light emitter 53 is accommodated and the cover member 52 is fitted, and an edge 54 b provided around the recess 54 a and used for attachment to the main body 51. The cover member 52 is bolted to the recess 54 a with respect to the unit body 54, and the edge part 54 b is bolted to the unit body 54 with respect to the main body 51.

発光体５３は、高輝度を有する例えば高輝度発光ダイオード等からなり、ユニット駆体５４の凹部５４ａに横断歩道２を横断している歩行者等に向けて発光するように設置されている。発光体５３の輝度は、ドライバーに横断歩道２を横断している歩行者等がはっきり認識でき、かつ、直線光によってドライバーの目がくらまされないように１０００〜１００００ｃｄ／ｍ2の範囲が好ましい。また、環境照度が０に近い状態（暗闇に近い状態）から薄暮時にかけて発光体５３に照らされた歩行者等の反射輝度が、横断歩道２の周囲の照度と１０００〜２０００ｃｄ／ｍ2程度の差を生じさせることにより、ドライバーに歩行者等ははっきりと認識されるようになり得る。 The light emitter 53 is composed of, for example, a high-intensity light-emitting diode having high brightness, and is installed in the recess 54a of the unit body 54 so as to emit light toward a pedestrian or the like crossing the pedestrian crossing 2. The luminance of the illuminant 53 is preferably in the range of 1000 to 10000 cd / m 2 so that a pedestrian or the like crossing the pedestrian crossing 2 can be clearly recognized by the driver and the driver's eyes are not blinded by linear light. In addition, the reflected luminance of a pedestrian or the like illuminated by the illuminant 53 from a state where the ambient illuminance is close to 0 (a state close to darkness) to the dusk is about 1000 to 2000 cd / m 2 with the illuminance around the pedestrian crossing 2 . By creating the difference, the driver can clearly recognize pedestrians and the like.

また、発光体５３は、横断歩道２を横断している歩行者等をある程度の範囲で照らすように、発光基台５３ａを斜めに支持して斜め上方に向けて設置されている。発光体５３から発光される光の角度αは、発光式道路鋲５から１ｍ離れた歩行者（平均身長１．７ｍ程度）をある程度の範囲で照らすことで認識させるとの考えから、道路１の路面に対して２０°〜６０°の範囲内、好ましくは３０°以上になるように設定されている。   Further, the light emitter 53 is installed obliquely upward and supports the light emitting base 53a so as to illuminate a pedestrian or the like crossing the pedestrian crossing 2 within a certain range. The angle α of the light emitted from the illuminant 53 can be recognized by illuminating a pedestrian (average height of about 1.7 m) 1 m away from the light-emitting road fence 5 to a certain extent. It is set within a range of 20 ° to 60 ° with respect to the road surface, preferably 30 ° or more.

そして、発光体５３への電力の供給や制御信号の送信等を行うケーブル（図示せず）を挿通させるためのケーブル挿通部５５が本体５１の側面に設けられるとともに、発光体５３の発光に係わる制御を行う制御部５６がユニット駆体５４の凹部５４ａに収納されている。   A cable insertion portion 55 for inserting a cable (not shown) for supplying power to the light emitter 53, transmitting a control signal, and the like is provided on the side surface of the main body 51 and relates to light emission of the light emitter 53. A control unit 56 that performs control is housed in the recess 54 a of the unit body 54.

次に、本実施形態の動作について説明する。夜間に信号機設備のない横断歩道２を歩行者等が横断しようとして横断歩道２の所定の検知エリアＡ内に入ると、検知センサー４が歩行者等の存在を検知して検知信号を送信する。これにより、横断歩道２に沿って道路１に埋設された複数の発光式道路鋲５が横断歩道２を横断している歩行者等に向けて所定時間、例えば３０秒前後の間発光し、複数の発光式道路鋲５から発光された光が横断歩道２を横断している歩行者等を照らす。   Next, the operation of this embodiment will be described. When a pedestrian or the like tries to cross the pedestrian crossing 2 without traffic light equipment at night and enters a predetermined detection area A of the pedestrian crossing 2, the detection sensor 4 detects the presence of the pedestrian or the like and transmits a detection signal. Thereby, a plurality of light-emitting road fences 5 embedded in the road 1 along the pedestrian crossing 2 emit light for a predetermined time, for example, about 30 seconds toward a pedestrian or the like crossing the pedestrian crossing 2. The light emitted from the light-emitting road fence 5 illuminates pedestrians crossing the pedestrian crossing 2.

本実施形態によれば、歩行者等の横断時に、横断歩道２に沿って道路１に埋設された複数の発光式道路鋲５が横断歩道２を横断している歩行者等に向けて発光するようにしたので、横断歩道２を横断している歩行者等が複数の発光式道路鋲５から発光される光でライトアップされて浮かび上り、横断歩道２に向かって走行中の車両のドライバーは横断歩道２を実際に横断している歩行者等の存在を極めて容易に認識することができる。従って、ドライバーは横断歩道を横断している歩行者等の存在に強く注意が喚起され、効果的に横断歩道での事故防止を図ることができる。   According to this embodiment, when a pedestrian or the like crosses, a plurality of light-emitting road fences 5 embedded in the road 1 along the pedestrian crossing 2 emit light toward a pedestrian or the like crossing the pedestrian crossing 2. As a result, pedestrians crossing the pedestrian crossing 2 are lighted up by the light emitted from the plurality of light-emitting road fences 5 and emerged. The presence of a pedestrian or the like actually crossing the pedestrian crossing 2 can be recognized very easily. Accordingly, the driver is strongly alerted to the presence of pedestrians crossing the pedestrian crossing, and can effectively prevent accidents at the pedestrian crossing.

また、本実施形態によれば、横断歩道２を横断している歩行者等に向けて発光する発光式道路鋲５を道路１に埋設するようにしたので、車両の走行を妨げずに横断歩道を横断している歩行者等を照らすことができ、横断歩道付近の交通の邪魔とはならない。   In addition, according to the present embodiment, the light-emitting road fence 5 that emits light toward a pedestrian or the like crossing the pedestrian crossing 2 is embedded in the road 1 so that the pedestrian crossing is not hindered. It can illuminate pedestrians crossing the road and does not interfere with traffic near the pedestrian crossing.

また、本実施形態によれば、横断歩道２に沿って複数の発光式道路鋲５を設置するようにしたので、複数の発光式道路鋲５により横断歩道２の全域に亘って横断している歩行者等を照らすことができ、歩行者等が横断歩道２のいずれの位置を横断していてもドライバーは確実に歩行者等の存在を認識することができる。   In addition, according to the present embodiment, since the plurality of light-emitting road fences 5 are installed along the pedestrian crossing 2, the plurality of light-emitting road fences 5 cross over the entire area of the pedestrian crossing 2. A pedestrian or the like can be illuminated, and the driver can surely recognize the presence of the pedestrian or the like even if the pedestrian or the like crosses any position of the pedestrian crossing 2.

また、本実施形態によれば、高輝度を有する発光体５３が用いられた発光式道路鋲５で横断歩道２を横断している歩行者等を照らすようにしたので、横断歩道を横断している歩行者等を高輝度で照らすことができ、ドライバーに横断歩道を横断している歩行者等がはっきり見えて認識し易い。   In addition, according to the present embodiment, since the illuminating road fence 5 using the luminous body 53 having high luminance is used to illuminate pedestrians crossing the pedestrian crossing 2 and the like, It is possible to illuminate pedestrians and the like with high brightness, and the pedestrians crossing the pedestrian crossing can be clearly seen and recognized by the driver.

また、本実施形態によれば、発光式道路鋲５を斜め上方に向けて発光するようにしたので、横断歩道２を横断している歩行者等のある程度範囲を照らすことができ、ドライバーに横断歩道２を横断している歩行者等の略全てが見えて認識し易い。   Further, according to the present embodiment, since the light-emitting road fence 5 emits light obliquely upward, it is possible to illuminate a certain range such as a pedestrian crossing the pedestrian crossing 2 and to cross the driver. It is easy to see and recognize almost all pedestrians crossing the sidewalk 2.

尚、発光式道路鋲５を発光させる検知センサー４の検知信号は、検知センサー４から発光式道路鋲５へ有線により伝達するようにしても良いし、検知センサー４から発光式道路鋲５に無線により伝達するようにしても良いが、検知センサー４の検知信号を無線により発光式道路鋲５に伝達するようにすれば、検知センサー４と発光式道路鋲５との間に面倒な配線工事が不要となり好ましい。   The detection signal of the detection sensor 4 that emits light from the light-emitting road fence 5 may be transmitted from the detection sensor 4 to the light-emitting road fence 5 by wire, or wirelessly transmitted from the detection sensor 4 to the light-emitting road fence 5. However, if the detection signal of the detection sensor 4 is transmitted wirelessly to the light-emitting road fence 5, troublesome wiring work is required between the detection sensor 4 and the light-emitting road fence 5. It is unnecessary and preferable.

また、発光式道路鋲５の発光に必要な電源は、商用電源を用いても良いし、太陽電池を用いても良いが、太陽電池を用いるのが簡便であり、太陽電池を用いれば商用電源ないところでも設置できる。   The power source necessary for the light emission of the light-emitting roadway 5 may be a commercial power source or a solar cell. However, it is easy to use a solar cell. It can be installed where there is not.
