Description

交通制御システムTraffic control system
 本発明は車両や歩行者等の移動体の安全かつ円滑な交通を確保する交通制御システムに関するものである。 The present invention relates to a traffic control system for securing safe and smooth traffic of moving objects such as vehicles and pedestrians.
 交通制御のための機器や構造物として信号機があり、車両や歩行者は信号機の信号表示にしたがって通行している。しかし、従来の信号機は、基本的に予め設定したプログラムで一方的に信号表示を行なう構成であるので、場合によっては安全かつ円滑な交通が確保されないことがある。例えば、交通量の変化や緊急車両に信号機の信号表示が臨機応変に対応できないことがあり、円滑な交通が阻害される。 There are traffic lights as equipment and structures for traffic control, and vehicles and pedestrians are passing according to the signal display of the traffic lights. However, since the conventional traffic signal basically has a configuration in which a signal is displayed unilaterally by a preset program, in some cases safe and smooth traffic may not be secured. For example, a change in traffic volume or an emergency vehicle may not be able to respond appropriately to the signal display of the traffic light, which hinders smooth traffic.

 特許文献1は、緊急車両の円滑な交通を目的としているので、一般車両の円滑な交通を実現することは難しい、例えば、交差点の一方方向の交通量が多いとき、これと交差する方向の交通量が少ないのにかかわらず、一方方向の信号機の赤表示によって渋滞が生じることを解消することはできない。また、右折専用レーンのない片側一車線の道路では、1台の右折車によって渋滞が生じることがあるが、これを解消することはできない。 Patent Document 1 aims at smooth traffic of emergency vehicles, so it is difficult to realize smooth traffic of ordinary vehicles. For example, when there is a large traffic volume in one direction of an intersection, traffic in a direction crossing this is difficult Despite the small amount, it is not possible to eliminate the occurrence of traffic congestion due to the red display of traffic lights in one direction. In addition, on a one-sided one-lane road without a right-turn lane, one right-turn car may cause congestion, but this can not be eliminated.
 特許文献2は、歩行者がユーザ携帯端末を操作して歩行者用信号機を制御する必要があるため、歩行者の負担が多い。また、複数の歩行者が存在して、それぞれが異なる操作を行うような場合には、歩行者用信号機の制御が複雑になる。 In Patent Document 2, since the pedestrian needs to operate the user portable terminal to control the pedestrian traffic signal, the burden on the pedestrian is heavy. In addition, when there are a plurality of pedestrians and each performs a different operation, the control of the pedestrian traffic signal becomes complicated.

In the control system, the traffic control means detects a moving object detection unit that detects a moving object, and a traffic condition detection unit that detects a traffic condition on the road from the detected movement and stop of the moving object. A marker display control unit is provided to control marker display of the structure to facilitate movement of the mobile body.
 本発明においては、移動体は自身の固有情報を含む情報担体を備えており、前記交通制御手段は、さらに情報担体から当該移動体の固有情報を検出する固有情報検出部を備えることが好ましい。この場合、標識表示制御部は、移動体検出部及び交通状態検出部で検出した移動体の交通状態と、固有情報検出部で検出した当該移動体の固有情報とを対比して当該移動体の移動を誘導するための標識表示を行うことが好ましい。 In the present invention, the mobile unit preferably includes an information carrier containing its own unique information, and the traffic control unit preferably further includes a unique information detection unit for detecting unique information of the mobile unit from the information carrier. In this case, the sign display control unit compares the traffic condition of the moving object detected by the moving object detecting unit and the traffic condition detecting unit with the unique information of the moving object detected by the unique information detecting unit, and It is preferable to carry out the label display for inducing movement.

(Embodiment 1)
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a conceptual view of a traffic control system according to a first embodiment of the present invention. Traffic control target road, in this case intersection CR is provided with structures such as traffic lights, road signs and street lights at predetermined positions. Traffic control according to the present invention is applied to traffic light SIG (general name) as this structure Means 1 is provided.
 この交通制御手段1は、交差点に配設されている複数の全ての信号機SIGに関連付けられた状態で配設されている。図1には、便宜的に4つの信号機SIG1~SIG4が図示されており、これら4つの信号機SIG1~SIG4のうち、主となる1つの信号機SIG1に交通制御手段1の制御本体11が配設されている。 The traffic control means 1 is disposed in association with all the plurality of traffic signals SIG disposed at the intersection. In FIG. 1, for convenience, four traffic signals SIG1 to SIG4 are illustrated, and among these four traffic signals SIG1 to SIG4, the control main body 11 of the traffic control means 1 is disposed at one main traffic signal SIG1. ing.
 図2は前記した主となる1つの信号機SIG1の概略図であり、当該信号機SIG1は、地上に立設されたポスト23に支持された信号表示部2を有している。この信号表示部2は少なくとも赤青黄色の信号灯21を備えるとともに、これらの信号灯21を駆動して標識のための点灯、点滅を実行する信号駆動部22を備えている。 FIG. 2 is a schematic view of the above-described one main traffic signal SIG1. The traffic signal SIG1 has a signal display unit 2 supported by posts 23 erected on the ground. The signal display unit 2 includes at least red, blue, yellow, and yellow signal lights 21 and a signal drive unit 22 that drives the signal lights 21 to execute lighting and blinking for signs.
 前記信号機SIG1には前記交通制御手段1の制御本体11が配設されている。この制御本体11は、信号機SIG1のポスト23に支持された制御キャビネット内に組み込まれている。後述するように、前記信号駆動部22は当該制御本体11によって前記信号灯21の点灯・点滅を制御する。 A control main body 11 of the traffic control means 1 is disposed in the traffic light SIG1. The control body 11 is incorporated in a control cabinet supported by the post 23 of the traffic light SIG1. As described later, the signal drive unit 22 controls the lighting / blinking of the signal light 21 by the control main body 11.
 前記信号機SIG1のポスト23の一部には、移動体を検出するための検出端末としての撮像手段10が配設されている。この撮像手段10は他の信号機SIG2~SIG4にも配設されている。この撮像手段10はCCDやCMOS撮像素子を用いたカメラで構成されており、交差点CR及びその近傍を通行する歩行者W、車両V等の移動体Mを撮像する。この場合、1つの撮像手段10で全ての移動体Mを撮像するようにしてもよく、あるいは複数の撮像手段10で撮像した画像を合成して全ての移動体Mを撮像するようにしてもよい。 An imaging means 10 as a detection terminal for detecting a mobile object is disposed on a part of the post 23 of the traffic light SIG1. The image pickup means 10 is also provided to the other traffic signals SIG2 to SIG4. The imaging unit 10 is configured of a camera using a CCD or a CMOS imaging device, and images a mobile object M such as a pedestrian W or a vehicle V passing through the intersection CR and the vicinity thereof. In this case, all the moving bodies M may be captured by one imaging unit 10, or all the moving bodies M may be captured by combining the images captured by a plurality of imaging units 10 .
 図3は前記制御本体11のブロック構成図であり、前記点灯駆動部22と、前記した検出端末としての前記各撮像手段10にそれぞれ無線接続する通信部12を備えている。ここでは電磁波や赤外線を利用して無線接続されている。この通信部12は、前記撮像手段10で撮像した画像を受信する一方で、前記信号駆動部22に対して信号駆動信号を送信する。 FIG. 3 is a block diagram of the control main body 11. The control main body 11 includes a communication unit 12 wirelessly connected to the lighting drive unit 22 and the imaging means 10 as the detection terminal. Here, wireless connection is made using electromagnetic waves and infrared rays. The communication unit 12 transmits a signal drive signal to the signal drive unit 22 while receiving an image captured by the imaging unit 10.
 また、前記制御本体11は、前記通信部12で受信した画像から個々の移動体を検出する移動体検出部13を備えている。この移動体検出部13は、撮像手段10で撮像した画像を画像解析することにより移動体Mを検出し、さらには歩行者Wや車両Vを識別して検出する。 Further, the control main body 11 is provided with a moving body detection unit 13 for detecting each moving body from the image received by the communication unit 12. The moving body detection unit 13 detects the moving body M by analyzing the image captured by the imaging unit 10, and identifies and detects the pedestrian W and the vehicle V.
 さらに、前記制御本体11は、検出した移動体Mに基づいて交差点CRでの交通状態を判断する交通状態検出部14を備えている。例えば、移動体検出部13で検出した移動体Mの経時的な位置変化、すなわち移動軌跡を求め、これから移動体Mの速度や進行方向等を検出する。そして、移動体Mが歩行者Wの場合には、歩行者Wが歩道や横断歩道を移動しているか、あるいは信号待ちしているか等の歩行状態を検出する。また、移動体Mが自転車や自動車等の車両Vの場合には、当該車両の標識灯(ウインカー等)の点灯状態を参照して直進、右折、あるいは左折する走行状態を検出する。 Furthermore, the control main body 11 is provided with a traffic state detection unit 14 that determines the traffic state at the intersection CR based on the detected mobile object M. For example, the temporal change in position of the movable body M detected by the movable body detection unit 13, that is, the movement trajectory is determined, and the speed, the traveling direction, and the like of the movable body M are detected therefrom. Then, when the movable body M is the pedestrian W, a walking state such as whether the pedestrian W is moving on a sidewalk or a pedestrian crossing or waiting for a signal is detected. In addition, when the mobile body M is a vehicle V such as a bicycle or a car, a traveling state in which the vehicle goes straight, right or left is detected with reference to the lighting state of a marker lamp (such as a turn signal) of the vehicle.
 前記制御本体11は、前記交通状態検出部14での検出に基づいて、信号機SIG1~SIG4の信号表示部2での信号表示を制御する標識表示制御部15を備えている。ここでは、標識表示制御部15は前記通信部12を介して交差点に存在する全ての信号機SIG1~SIG4の信号駆動部22に無線で接続されており、これら信号機SIG1~SIG4の点灯状態を制御する。この場合、各信号機SIG1~SIG4に対しては、特定の信号機の青信号の時間を長くし、他の信号機の赤信号の時間を長くする等の任意の標識表示の制御を行うことが可能とされている。 The control main body 11 includes a sign display control unit 15 that controls the signal display of the signal display unit 2 of the traffic signals SIG1 to SIG4 based on the detection by the traffic condition detection unit 14. Here, the sign display control unit 15 is wirelessly connected to the signal drive units 22 of all the traffic signals SIG1 to SIG4 present at the intersection via the communication unit 12, and controls the lighting states of the traffic signals SIG1 to SIG4. . In this case, for each of the traffic signals SIG1 to SIG4, it is possible to perform control of any sign display, such as lengthening the time of the green light of a specific traffic light and increasing the time of the red light of other traffic light ing.
 この標識表示制御部15では、例えば、過去における種々の交通状態と、そのときの信号機の点灯制御の履歴を記憶する記憶部(図示せず)を備えておき、現在の交通状態と、記憶されている過去の種々の交通状態と、そのときにおける信号機の点灯制御結果を対比することにより、それぞれにおける信号機の好適な点灯制御を行うように構成してもよい。すなわち、信号制御に学習機能を持たせ、最も好適な信号制御を実行することが可能である。 The sign display control unit 15 includes, for example, a storage unit (not shown) that stores various traffic states in the past and a history of lighting control of the traffic light at that time, and stores the current traffic state. By contrasting various traffic conditions in the past with the lighting control result of the traffic light at that time, suitable lighting control of the traffic light in each may be performed. That is, it is possible to give a learning function to signal control and to execute the most suitable signal control.
 以上説明した交通制御手段1を備える交通制御システムによる代表的な制御形態例を図4を参照して説明する。先ず、交通制御手段1では、撮像手段10で撮像した交差点の画像から、移動体検出部13が移動体M、さらには歩行者W、車両Vを検出する。次いで、検出した移動体に基づいて、交通状態検出部14において歩行者Wや車両Vの移動状態を認識し、この移動状態に基づいて交差点CRにおける交通状態を検出する。 A typical control form example by the traffic control system provided with the traffic control means 1 described above will be described with reference to FIG. First, in the traffic control means 1, the moving body detection unit 13 detects the moving body M, and further the pedestrian W and the vehicle V from the image of the intersection captured by the imaging means 10. Next, based on the detected moving object, the traffic state detection unit 14 recognizes the movement state of the pedestrian W or the vehicle V, and detects the traffic state at the intersection CR based on the movement state.
 図4Aの場合は、交差点CRにおける一方向R1の車両Vの交通量が多く、これと交差する他方向R2の交通量が少ない状況にあり、そのため一方向側の信号機SIG2,SIG4が赤信号表示になると渋滞が生じ易くなる。交通制御手段1は、移動体検出部13で各方向の車両Vの交通量を検出し、交通状態検出部14において両方向の交通量を比較するとともに、各車両Vの移動状態を検出する。 In the case of FIG. 4A, the traffic volume of the vehicle V in one direction R1 at the intersection CR is large, and the traffic volume in the other direction R2 crossing this is small, so the traffic signals SIG2 and SIG4 on one side are red Traffic jams are likely to occur. The traffic control means 1 detects the traffic volume of the vehicle V in each direction with the mobile object detection unit 13, compares the traffic volume in both directions with the traffic condition detection unit 14, and detects the movement condition of each vehicle V.
 そして、一方向R1の交通量が他方向R2の交通量よりも顕著に多く、渋滞が生じ易い状態であることを検出すると、標識表示制御部15は、一方向側の信号機SIG2,SIG4の青信号の時間を、他方向側の信号機SIG1,SIG3の青信号の時間よりも長くする制御信号を出力する。この制御信号は通信部12を介して各信号機SIG1~SIG4の信号駆動部22に送信され、各信号機SIG1~SIG4の信号表示が制御される。これにより、一方向側の車両Vが交差点を通過し易くなり、交通量の差が要因となる交差点CRでの渋滞が解消される。 Then, when it is detected that traffic volume in one direction R1 is significantly larger than traffic volume in the other direction R2 and traffic congestion is likely to occur, the sign display control unit 15 detects the green signals of the traffic signals SIG2 and SIG4 on one side. The control signal is output to make the time of time longer than the time of the blue signal of the traffic signals SIG1 and SIG3 on the other direction side. The control signal is transmitted to the signal drive unit 22 of each of the traffic signals SIG1 to SIG4 via the communication unit 12, and the signal display of each of the traffic signals SIG1 to SIG4 is controlled. As a result, the vehicle V on one side easily passes through the intersection, and the congestion at the intersection CR caused by the difference in traffic volume is eliminated.
 図4Bの場合は、右折専用レーンのない交差点CRにおいて、一方向道路R1側において1台の右折車V1によって後続車両Vに渋滞が生じている。交通制御手段1は、移動体検出部13で車両Vを検出し、交通状態検出部14において交差点CRにおける各車両Vの走行状態を検出する。渋滞を検出した場合には、各車両V1,Vの車速や、停止している時間等を検出する。また、同時に対向車線側の車両Vの交通量を検出する。 In the case of FIG. 4B, at the intersection CR where there is no right turn lane, a traffic jam occurs in the following vehicle V by one right turn vehicle V1 on the one-way road R1 side. The traffic control means 1 detects the vehicle V by the moving body detection unit 13, and detects the traveling state of each vehicle V at the intersection CR by the traffic state detection unit 14. When a traffic jam is detected, the vehicle speed of each of the vehicles V1 and V, the stopping time, and the like are detected. At the same time, the traffic volume of the vehicle V on the opposite lane side is detected.
 標識表示制御部15は、検出した渋滞している車両Vの停止時間が所定時間を越えたときには、対向車線側の車両Vの交通量を参照し、右折車が優先的に右折できように、対向車線側の信号機SIG2を臨時的な赤信号に制御する。右折車V1が右折して渋滞が緩和されたら、対向車側の信号機SIG2を青信号に戻す制御を行う。これにより、渋滞が解消される。 When the detected stop time of the congested vehicle V exceeds a predetermined time, the sign display control unit 15 refers to the traffic volume of the vehicle V on the opposite lane side so that the right-turning vehicle can turn to the right preferentially. The traffic light signal SIG2 on the opposite lane side is controlled to a temporary red light. When the right turn vehicle V1 turns to the right to alleviate the traffic congestion, control is performed to return the oncoming traffic signal SIG2 to a green light. This eliminates the traffic jam.
 この場合、図2に示されているように、信号機SIG(SIG4)に矢印表示の補助信号機3を設けておき、右折車V1に対して当該補助信号機3を点灯させるようにしてもよい。また、図示は省略するが、これと同時に対向車側の信号機SIG(SIG2)においては、右折車を優先させるための臨時的な赤信号であることを表示するために、赤信号を特異な周期で点滅させる表示としてもよい。 In this case, as shown in FIG. 2, the auxiliary signal 3 indicated by the arrow may be provided in the signal SIG (SIG4), and the auxiliary signal 3 may be turned on for the right turn vehicle V1. Also, although not shown, at the same time on the traffic signal SIG (SIG2) on the oncoming vehicle side, in order to indicate that it is a temporary red signal for giving priority to the right turn, the red signal has a unique cycle It may be displayed as flashing.
 図4Cの場合は、歩行者W1が横断歩道を横断しており、また歩行者W2が信号待ちしている。交通制御手段1は、移動体検出部13においてこれら歩行者W1,W2を検出すると、道路状態検出部14は、歩行者W1の歩行速度を検出し、また歩行者W2の信号待ち時間を検出する。 In the case of FIG. 4C, the pedestrian W1 crosses the pedestrian crossing and the pedestrian W2 is waiting for a signal. When the traffic control means 1 detects the pedestrians W1 and W2 in the mobile object detection unit 13, the road state detection unit 14 detects the walking speed of the pedestrian W1 and detects the signal waiting time of the pedestrian W2 .
 標識表示制御部15は、検出した歩行者W1の歩行速度が所定速度よりも遅いとき、すなわち歩行者が幼児や高齢者のような場合には、対応する信号機SIG1の青信号を歩行者W1が完全に渡り切るまで継続することにより、歩行者W1の安全を確保する。また、歩行者W2の待ち時間と、交差する道路の車両Vの交通量を参照し、待ち時間が所定時間を越え、かつ交差する道路における交通量が所定量よりも少ないときには、歩行者W2に対応する信号機SIG2の赤信号の時間を短くし、歩行者W2の信号待ち時間を短縮する。 When the detected walking speed of the pedestrian W1 is lower than a predetermined speed, that is, when the pedestrian is an infant or an elderly person, the sign display control unit 15 completes the green signal of the corresponding signal SIG1 by the pedestrian W1. The safety of the pedestrian W1 is secured by continuing until crossing the road. Also, referring to the waiting time of the pedestrian W2 and the traffic volume of the vehicle V on the intersecting road, when the waiting time exceeds a predetermined time and the traffic volume on the intersecting road is smaller than the predetermined amount, The time of the red signal of the corresponding traffic signal SIG2 is shortened, and the signal waiting time of the pedestrian W2 is shortened.
 このように、実施形態1の交通制御システムは、移動体検出部13により交差点における移動体を検出し、さらに交通状態検出部14が交通状態を検出し、標識表示制御部15において最大多数の移動体が円滑に交通できるような信号機の制御を行う。これにより、歩行者や車両を含めた交差点における円滑な交通が確保される。 As described above, in the traffic control system according to the first embodiment, the moving object detection unit 13 detects the moving object at the intersection, and the traffic condition detecting unit 14 detects the traffic condition. Control traffic lights that allow the body to travel smoothly. This ensures smooth traffic at intersections including pedestrians and vehicles.
 ここで、本発明における交通制御手段1の移動体検出部13は、交差点における移動体を検出し、かつ交通状態検出部14において当該移動体による交通状態が検出できるのであれば、実施形態1の撮像手段10で撮像した画像に基づく移動体の検出に代えて、LiDAR、ミリ波レーダー等による検出信号を利用して移動体を検出する構成としてもよい。 Here, if the mobile object detection unit 13 of the traffic control means 1 in the present invention detects a mobile object at an intersection, and the traffic condition detection unit 14 can detect the traffic condition by the mobile object, the first embodiment Instead of detecting the moving object based on the image captured by the imaging unit 10, the moving object may be detected using a detection signal by LiDAR, millimeter wave radar or the like.
 実施形態1では、交通制御手段1の制御本体11を1つの信号機SIG1に配設しているが、制御本体11を複数の信号機にそれぞれ配設し、それぞれの制御本体11を撮像手段10や信号部2に有線で接続するとともに、各制御本体11を相互に無線又は有線で接続した構成としてもよい。また、交通制御手段1は信号機以外の道路標識、街灯、掲示板、その他の建造物に配設されてもよい。 In the first embodiment, the control main body 11 of the traffic control means 1 is disposed in one traffic signal SIG1, but the control main body 11 is disposed in each of a plurality of traffic lights, and each control main body 11 is an imaging means 10 or a signal The control unit 11 may be connected to the unit 2 by wire and the control units 11 may be connected to each other by wireless or by wire. Also, the traffic control means 1 may be disposed on road signs other than traffic lights, street lights, billboards, and other structures.
 実施形態1では、信号機のある交差点に適用した形態を示したが、交差点以外に設置されている信号機に対しても適用することが可能である。 Although the form applied to the intersection with a signal was shown in Embodiment 1, it is possible to apply also to the signal installed in places other than an intersection.
(実施形態2)
 図5は実施形態2における信号機SIGの概略図である。すなわち、図1に示した実施形態1と同様に交差点に複数の信号機SIGが配設されているとした場合、各信号機SIGには信号表示部2に加えて表示画面を有する電光掲示板4が配設されている。この電光掲示板4は交通制御手段1での制御により、表示画面に任意のパターンや文字を表示することが可能とされている。例えば、図示は省略するが、電光掲示板4を駆動する駆動部(図示せず)は実施形態1と同様に制御本体11の通信部12に無線接続されている。
Second Embodiment
FIG. 5 is a schematic view of the traffic light SIG in the second embodiment. That is, assuming that a plurality of traffic signals SIG are disposed at intersections as in the first embodiment shown in FIG. 1, in each of the traffic signals SIG, an electric light bulletin board 4 having a display screen in addition to the signal display unit 2 is disposed. It is set up. Under the control of the traffic control means 1, this electronic bulletin board 4 is capable of displaying any pattern or character on the display screen. For example, although not shown, a drive unit (not shown) for driving the electronic bulletin board 4 is wirelessly connected to the communication unit 12 of the control main body 11 as in the first embodiment.
 また、実施形態2では、歩行者や車両は、自身の固有情報が記憶された情報担体5を保有している。この情報担体5は、例えばICチップ51であり、図6(a)に示すように、歩行者Wはバッグ等の携帯物やベルト等の装身具にICチップ51を取り付けている。また、災害時や交通安全のために装着するヘルメットにICチップ51を取り付けてもよい。このICチップ51は、ICカードに搭載されているICチップを利用してもよい。さらには、情報担体5はICチップに代えて、携帯電話機やスマートフォン等の携帯通信機に設けられている記憶媒体で構成してもよい。 In the second embodiment, the pedestrian or the vehicle holds the information carrier 5 in which the unique information of the pedestrian is stored. The information carrier 5 is, for example, an IC chip 51. As shown in FIG. 6A, the pedestrian W attaches the IC chip 51 to a portable object such as a bag or an accessory such as a belt. In addition, the IC chip 51 may be attached to a helmet worn for disasters or traffic safety. The IC chip 51 may use an IC chip mounted on an IC card. Furthermore, the information carrier 5 may be configured by a storage medium provided in a mobile communication device such as a mobile phone or a smartphone instead of the IC chip.
 また、図6(b)に示すように、車両Vには情報担体5として、ランプや車体の一部、例えば、ハイマウントストップランプ、シャークフィンアンテナ、樹脂製ウインド(リアウインド)や樹脂製ボディに、それぞれICチップ51を搭載している。 Further, as shown in FIG. 6 (b), as the information carrier 5, for the vehicle V, a lamp or a part of a vehicle body, for example, a high mount stop lamp, a shark fin antenna, a resin window (rear window) or a resin body Each has an IC chip 51 mounted thereon.
 あるいは、情報担体5は、図6(c)に示すように、ICチップに代えて、車両Vの車体の一部、例えばトランクリッドやボンネットの外表面に、肉眼では識別不可能な材料で印刷した特異な情報パターン52で構成してもよい。なお、この情報パターン52は歩行者のヘルメットの表面に設けることも可能である。 Alternatively, as shown in FIG. 6C, the information carrier 5 is printed with a material that can not be distinguished by naked eyes on a part of the vehicle body of the vehicle V, for example, a trunk lid or bonnet instead of the IC chip. It may be configured by the unique information pattern 52. The information pattern 52 can also be provided on the surface of a pedestrian helmet.
 図7は実施形態2の交通制御手段1の制御本体11のブロック構成図である。実施形態1の制御本体11と等価な部分には同一符号を付してある。ここで、移動体検出部13は、移動体が有している情報担体5を検出することにより移動体を検出することが可能とされている。そのため、移動体の検出端末として、例えば、ICチップ51を無線(電磁波)で検出するICセンサー、車両やヘルメット等に印刷された情報パターン52に特定波長の光を照射し、その反射光を検出することにより当該情報パターン52を光学的に検出する光学検出器が利用できる。また、この場合には、図5に鎖線で示した検査端末としての撮像手段10を省略することができる。 FIG. 7 is a block diagram of the control main body 11 of the traffic control means 1 of the second embodiment. The parts equivalent to those of the control main body 11 of the first embodiment are given the same reference numerals. Here, the mobile detection unit 13 is capable of detecting the mobile by detecting the information carrier 5 included in the mobile. Therefore, as a detection terminal of a moving body, for example, an IC sensor that detects the IC chip 51 wirelessly (electromagnetic wave), the light of specific wavelength is irradiated to the information pattern 52 printed on a vehicle or helmet, etc. Thus, an optical detector that optically detects the information pattern 52 can be used. Further, in this case, the imaging means 10 as an inspection terminal shown by a chain line in FIG. 5 can be omitted.
 また、情報担体5としてICチップ51に代えて移動体が携帯している携帯通信機を利用する場合には、検出端末として無線通信を行って移動体を検出する無線機が利用できる。この場合、無線機は制御本体11に設けられている通信部12を利用することができる。また、情報担体として、車両に装備されているナビゲーション装置やETC装置等の無線機器を利用し、これらを通信部12にて検出することにより車両Vを検出することも可能である。 When a portable communication device carried by a mobile is used as the information carrier 5 instead of the IC chip 51, a wireless device for detecting a mobile by performing wireless communication as a detection terminal can be used. In this case, the wireless device can use the communication unit 12 provided in the control main body 11. In addition, it is possible to detect the vehicle V by using the wireless device such as a navigation device or an ETC device equipped in the vehicle as the information carrier and detecting these by the communication unit 12.
 さらに、実施形態2の制御本体11は、前記情報担体5を検出することにより移動体の固有情報を検出する固有情報検出部16が設けられている。この固有情報検出部16は前記情報担体5、すなわちICチップ51に記憶され、あるいは情報パターン52に含まれている情報を検出することにより、移動体の固有情報を検出することができる。例えば、歩行者Wの固有情報から、高齢者、児童、障害者等が検出できる。また、車両Vの固有情報から、緊急車両、高齢者運転車両、初心者運転車両等が検出できる。 Furthermore, the control main body 11 of the second embodiment is provided with a unique information detection unit 16 that detects unique information of a mobile by detecting the information carrier 5. The unique information detection unit 16 can detect the unique information of the mobile by detecting the information stored in the information carrier 5, that is, the IC chip 51 or included in the information pattern 52. For example, elderly people, children, disabled people, etc. can be detected from the unique information of the pedestrian W. Moreover, an emergency vehicle, an elderly person driving vehicle, a novice driving vehicle, etc. can be detected from the specific information of the vehicle V.
 実施形態2における交通制御手段1による制御は、図1に示した実施形態1での制御と同様であるが、これに加えて固有情報検出部16で検出した移動体の固有情報に基づいて、標識表示制御手段15において信号機SIGのより細かい信号制御が可能になる。例えば、検出した歩行者Wの固有情報から、歩行者Wが障害者の場合には、横断歩道を横断する際の青時間をさらに長く制御する。また、児童の場合には信号機SIGに併設されている電光掲示板4に児童が横断中であることの表示を行う。 The control by the traffic control means 1 in the second embodiment is the same as the control in the first embodiment shown in FIG. 1, but in addition to this, based on the specific information of the mobile detected by the specific information detection unit 16 In the sign display control means 15, finer signal control of the traffic light SIG becomes possible. For example, in the case where the pedestrian W is a disabled person, the blue time when crossing the pedestrian crossing is controlled to be longer from the specific information of the detected pedestrian W. In addition, in the case of a child, an indication that the child is crossing is displayed on the electric light bulletin board 4 attached to the signal apparatus SIG.
 車両Vに対する信号制御も実施形態1と同様であるが、特に、情報担体5の固有情報から緊急車両を検出した場合には、当該緊急車両が交差点に接近したときには、その方向の信号機を優先的に青信号として円滑な移動を可能にする。あるいは、複数台が連なって走行する団体バスの場合には、全部のバスが通過するまで青信号とする。 The signal control for the vehicle V is also the same as in the first embodiment, but particularly when an emergency vehicle is detected from the specific information of the information carrier 5, when the emergency vehicle approaches an intersection, the traffic signal in that direction is prioritized. Enable smooth movement as a green light. Alternatively, in the case of a group bus that travels in series, a green light is provided until all the buses pass.
 また、交差点CRで事故が生じたときには、そのときの交通状態に応じて交差点CRにおける全ての信号機SIGの赤信号と青信号の時間を適宜に制御する。特に、被害者、加害車両等の情報担体5の固有情報から、救急や消防、警察への通報を選択肢の一つとする。合せて、検出した緊急車両の円滑な移動を制御する。これらにより、事故が生じたときの車両Vの渋滞を緩和し、かつ緊急車両が迅速に到着できるようにし被害者等の救護を可能とする。 Further, when an accident occurs at the intersection CR, the times of red and green lights of all the traffic lights SIG at the intersection CR are appropriately controlled according to the traffic condition at that time. In particular, based on the unique information of the information carrier 5 such as the victim, the harmed vehicle, etc., the emergency, the fire, and the report to the police are taken as one of the options. At the same time, control the smooth movement of the detected emergency vehicle. As a result, the congestion of the vehicle V in the event of an accident can be alleviated, and the emergency vehicle can arrive quickly, thereby making it possible to rescue a victim or the like.
 実施形態2では車両V、特に自動車に情報担体5を備えることにより、情報担体5で当該自動車を特定することができるので、例えば、前部ナンバープレートの取り付け位置を変更し、あるいは撤去することも可能になる。前者の場合には歩行者との接触事故が生じたときに、歩行者に対するダメージを緩和する。後者の場合には、さらに自動車の軽量化による燃費向上が可能になる。 In the second embodiment, the vehicle V can be identified by the information carrier 5 by providing the information carrier 5 in the vehicle V, in particular, a car, so that, for example, the attachment position of the front number plate can be changed or removed. It will be possible. In the former case, when a contact accident with a pedestrian occurs, damage to the pedestrian is mitigated. In the latter case, it is possible to further improve the fuel consumption by reducing the weight of the vehicle.
 実施形態2の情報担体5は、交通状態を制御するための利用に限定されるものではなく、災害時に歩行者の情報担体5により非難者の確認に利用できる。また、自動運転車等の無人移動体に適用でき、さらには情報担体5から当該無人移動体の情報を取得することにより、例えば目的地、進路等を読み取り、無人移動体が円滑に移動できるように信号機を制御する。 The information carrier 5 of the second embodiment is not limited to the use for controlling traffic conditions, and can be used for confirmation of a accused person by the pedestrian information carrier 5 at the time of disaster. In addition, it can be applied to an unmanned mobile unit such as an autonomous vehicle, and further, by acquiring information of the unmanned mobile unit from the information carrier 5, for example, a destination, a course, etc. can be read and the unmanned mobile unit can be moved smoothly. Control the traffic lights.
