以下本発明の実施形態について図面を参照して説明する。   Embodiments of the present invention will be described below with reference to the drawings.

図１は本発明の交通の乱れによる事故予防警告装置の実施形態を示す構成図である。   FIG. 1 is a block diagram showing an embodiment of an accident prevention warning device due to traffic disturbance of the present invention.

図１において、１ａ〜１ｄは、交通の乱れが発生し易い箇所の高速道路に沿って適宜の間隔、例えば５００ｍの間隔を存して設置された交通量計測装置（トラフィックカウンタ、以下「トラカン」と略称する）で、このトラカン１ａ〜１ｄは、例えば路面に埋設された一対のループコイルにより道路縦断方向の通過車両を電気信号として計測するものである。なお、トラカンとしてはループコイル以外に超音波方式などがある。   In FIG. 1, reference numerals 1a to 1d denote traffic measuring devices (traffic counters, hereinafter referred to as “tracans”) installed at an appropriate interval, for example, an interval of 500 m, along a highway where traffic disturbance is likely to occur. The tracans 1a to 1d measure a passing vehicle in the longitudinal direction of the road as an electrical signal by a pair of loop coils embedded in the road surface, for example. In addition to the loop coil, there is an ultrasonic method other than the loop coil.

また、２ａ〜２ｄは車両の進行方向から見て最初のトラカン１ａの設置点より５００ｍ後方のトラカン１ｂを起点として５００ｍ間隔毎に第１乃至第４のブロックに分け、さらに各ブロックに複数の警報発生装置（自発光デリニェータ）がそれぞれ設置され、また各ブロックの最後方には渋滞表示板３がそれぞれ設置されている。   In addition, 2a to 2d are divided into first to fourth blocks at intervals of 500 m starting from the trakan 1b that is 500 m behind the installation point of the first tracan 1a when viewed from the traveling direction of the vehicle. A generator (self-luminous delineator) is installed, and a traffic jam display board 3 is installed at the end of each block.

これら各ブロックの自発光デリニェータ２ａ〜２ｄは、図２（ａ）及び（ｂ）に示すように例えば５０ｍ間隔で走行路肩及び中央分離帯に対向させて１０個ずつ図示しない支柱に取付けてそれぞれ鉛直に設置される。   As shown in FIGS. 2 (a) and 2 (b), the self-light-emitting delineators 2a to 2d of these blocks are vertically mounted by attaching 10 blocks, for example, to the running road shoulder and the central separation band at intervals of 50 m. Installed.

この自発光デリニェータ２は、図３（ａ），（ｂ）に示すようにケース２１内に取付基板２２に取付けられた複数個の例えば橙色発光ＬＥＤ２３が収納され、またケース２１の表示窓に設けられた前面枠２２には前面ガラス２３が取付けられた構成のもので、通常視線誘導に供されているものである。また、橙色発光ＬＥＤ２４に対しては、点滅周期が例えば８０回／分とし、昼間運用時には例えば光度１２０ｃｄ以上、夜間運用時は電圧調整による調光制御により光度８０ｃｄ以上（輝度：低）に調光できるようになっている。   As shown in FIGS. 3 (a) and 3 (b), the self-light-emitting delineator 2 houses a plurality of, for example, orange light-emitting LEDs 23 attached to a mounting substrate 22 in a case 21, and is provided in a display window of the case 21. The front frame 22 has a structure in which a front glass 23 is attached and is usually used for visual line guidance. For the orange light emitting LED 24, the blinking cycle is, for example, 80 times / minute, and for example, the luminous intensity is 120 cd or more during daytime operation, and the luminous intensity is controlled to 80 cd or more (luminance: low) by dimming control by voltage adjustment during nighttime operation. It can be done.

一方、４はデリニェータ制御盤で、このデリニェータ制御盤４は各設置点のトラカン１ａ〜１ｄに対応させて設けられ、トラカン１ａ〜１ｄでそれぞれ計測された通過車両の測定信号から通過車両の通過時刻と通過速度を検知する検知部５ａ〜５ｄと、これらの検知部５ａ〜５ｄにより検知された通過車両台数及び通過速度に対して詳細を後述する事故予防警告発生判定ロジックにより予め特定された交通の乱れの要因となる通過台数及び通過速度により警報発生状態の有無を判定する事故予防警告発生判定部６と、この事故予防警告発生判定部６の判定結果に基づいて自発光デリニェータ２ａ〜２ｄを点灯・消灯制御するための処理を実行する制御処理部７と、この制御処理部７で制御処理された情報に基づいて各ブロックの車両進行方向から見て後方端に設置された渋滞表示板３ａ〜３ｄ、ブロック毎に自発光デリニェータ２ａ〜２ｄを点灯・消灯する制御信号を出力する渋滞表示板制御部８及び第１〜第４ブロック制御部９ａ〜９ｄとを備えている。   On the other hand, 4 is a delineator control panel, and this delineator control panel 4 is provided corresponding to the tracans 1a to 1d at the respective installation points, and the passing time of the passing vehicle is determined from the measurement signals of the passing vehicles respectively measured by the tracans 1a to 1d. The detection units 5a to 5d for detecting the passing speed, and the number of passing vehicles detected by the detecting units 5a to 5d and the passing speed of the traffic specified in advance by the accident prevention warning occurrence determination logic described in detail later. Accident prevention warning occurrence determination unit 6 that determines the presence or absence of an alarm generation state based on the number of passing passages and the passage speed that cause disturbance, and the self-light-emitting delineators 2a to 2d are turned on based on the determination result of the accident prevention warning generation determination unit The control processing unit 7 that executes processing for controlling the turn-off and the vehicle traveling direction of each block based on the information processed by the control processing unit 7 The traffic congestion display boards 3a to 3d installed at the rear end when viewed from the front, the traffic congestion display board control section 8 for outputting control signals for turning on / off the self-light-emitting delineators 2a to 2d for each block, and the first to fourth block control sections 9a-9d.

この場合、デリニェータ制御盤４は、図２に示すように監視所の電気室１０及び通信機械室１１より電源線１２及び制御線１３を通して伝送される制御信号及び電力を受ける電源用接続端子１４及び通信用接続端子１５にそれぞれ接続される。   In this case, as shown in FIG. 2, the delineator control panel 4 includes a power connection terminal 14 for receiving control signals and power transmitted from the electrical room 10 and the communication machine room 11 of the monitoring station through the power line 12 and the control line 13, and Each is connected to a communication connection terminal 15.

一方、１６はセンタに設置されたデータ収集装置で、このデータ収集装置１６はデリニェータ制御盤４の制御処理部７で制御処理された交通の乱れによる警報発生状態の有無情報を収集して全体の交通の流れを監視するものである。   On the other hand, 16 is a data collection device installed in the center. This data collection device 16 collects information on the presence or absence of an alarm occurrence state due to traffic disturbance controlled by the control processing unit 7 of the delineator control panel 4 and It monitors traffic flow.

次にこのように構成された交通の乱れによる事故予防警告装置の作用を述べる。   Next, the operation of the accident prevention warning device due to traffic disturbance constructed as described above will be described.

まず、交通事故予防警告発生判定部６において、トラカンの計測値に対する交通の乱れの要因となる車両の通過台数及び通過速度の関係の検証について図４により説明する。   First, the verification of the relationship between the number of passing vehicles and the passing speed that cause the traffic disturbance with respect to the measured value of the traffic can be described with reference to FIG.

本実施形態では、５００ｍ間隔で設置された各トラカン１ａ〜１ｄの連続する１０秒間毎の計測値として、
（１）交通量（車両通過台数）が４台以上で、全ての車両の走行速度が５０（ｋｍ／ｈ）以下で３０（ｋｍ／ｈ）を超える場合
（２）交通量が４台未満であるが、車両の走行速度が３０（ｋｍ／ｈ）以下の場合
は交通の流れに乱れが発生、つまり渋滞発生と判定して警告信号を出力する。 In this embodiment, as the measured value for every 10 seconds that each of the tracans 1a to 1d installed at intervals of 500 m continues,
(1) When the traffic volume (number of vehicles passing) is 4 or more and the traveling speed of all vehicles is 50 (km / h) or less and exceeds 30 (km / h) (2) The traffic volume is less than 4 However, when the traveling speed of the vehicle is 30 (km / h) or less, the traffic flow is disturbed, that is, it is determined that a traffic jam has occurred, and a warning signal is output.

本発明では、それぞれの通過車両において、判定を実行するが、検証及び例示のため、連続する任意の１０秒間の計測で、４回目、９回目、１３回目が上記（１）に該当していることを示している。   In the present invention, the determination is executed in each passing vehicle. For the purpose of verification and illustration, the fourth time, the ninth time, and the thirteenth time correspond to the above (1) in arbitrary continuous measurement for 10 seconds. It is shown that.

また、交通量計測装置では、連続する交通状況を計測しているため、５００ｍの設置間隔であっても、数十秒程度の遅れで、（１）または（２）に該当する計測値を得ることができるので、特に密に多くの交通量計測装置を設置する必要がない。   In addition, since the traffic measuring device measures continuous traffic conditions, a measured value corresponding to (1) or (2) is obtained with a delay of about several tens of seconds even at an installation interval of 500 m. Therefore, it is not necessary to install a lot of traffic volume measuring devices in particular.

次にこのような検証結果に基づく交通の乱れによる警告予防信号の発生手順について図５に示すフローチャートにより説明する。   Next, a procedure for generating a warning prevention signal due to traffic disturbance based on the verification result will be described with reference to a flowchart shown in FIG.

いま、図１において、各設置点のトラカン１ａ〜１ｄにより通過車両が計測され、デリニェータ制御盤４の検知部５ａ〜５ｄにそれぞれ入力されているものとする。すると、各検知部５ａ〜５ｄにより各トラカン１ａ〜１ｄで計測された信号から通過車両の通過時間及び通過速度が検知されると、これらの情報が事故予防警告発生判定部６に取込まれ、事故予防警告発生判定ロジックが起動される。   In FIG. 1, it is assumed that passing vehicles are measured by the tracans 1 a to 1 d at the respective installation points and are input to the detection units 5 a to 5 d of the delineator control panel 4. Then, when the passing time and passing speed of the passing vehicle are detected from the signals measured by the respective tracans 1a to 1d by the detecting units 5a to 5d, these pieces of information are taken into the accident prevention warning generation determining unit 6, The accident prevention warning occurrence determination logic is activated.

まず、ステップＳ１にて通過車両１台毎における過去１０秒以内の車両の平均速度Ｖ（ｋｍ／ｈ）を求め、ステップＳ２にてこの平均速度が５０（ｋｍ／ｈ）を超えるか否かを判定し、５０（ｋｍ／ｈ）を超えればステップＳ１に戻り、引き続き過去１０秒以内の車両の平均速度を求める。   First, in step S1, an average speed V (km / h) of the vehicle within the past 10 seconds for each passing vehicle is obtained, and in step S2, whether or not the average speed exceeds 50 (km / h). If it exceeds 50 (km / h), the process returns to step S1, and the average speed of the vehicle within the past 10 seconds is continuously obtained.

次いで、ステップＳ２にて車両の平均速度が５０（ｋｍ／ｈ）を超えなければ、ステップＳ３にて平均速度Ｖが３０（ｋｍ／ｈ）を超え、かつ５０（ｋｍ／ｈ）以下の条件を満たしているか否かを判定し、満たしていればステップＳ４にて通過車両１台毎における過去１０秒以内に４台以上の車両通過があるか否かを判定し、４台以上（過去の台数Ｎ＝３台）あればステップＳ５にて事故予防警告発生状態と判定する。また、上記の条件を満たしていない場合には、ステップＳ６にて平均速度が０を超え、かつ３０（ｋｍ／ｈ）以下であるとしてステップＳ５にて渋滞と判定する。   Next, if the average speed of the vehicle does not exceed 50 (km / h) in step S2, the condition that the average speed V exceeds 30 (km / h) and is 50 (km / h) or less in step S3. In step S4, it is determined whether there are four or more vehicles passing within the past 10 seconds for each passing vehicle, and four or more (past number) If N = 3), it is determined in step S5 that an accident prevention warning has occurred. If the above condition is not satisfied, it is determined in step S5 that the average speed exceeds 0 and is 30 (km / h) or less in step S5.

そして、ステップＳ５にて事故予防警告発生状態と判定されると、その判定出力により制御処理部７が起動され、自発光デリニェータ２ａ〜２ｄを点灯・消灯制御する制御ロジックへ移行する。   When it is determined in step S5 that an accident prevention warning has occurred, the control processing unit 7 is activated by the determination output, and the process proceeds to a control logic for controlling on / off of the self-luminous delineators 2a to 2d.

次にこの制御ロジックによる点灯・消灯制御手順について図６に示すフローチャートにより説明する。   Next, the lighting / extinguishing control procedure by this control logic will be described with reference to the flowchart shown in FIG.

いま、点灯・消灯制御ロジックが起動されると、ステップＳ７にて交通量計測装置（トラカン）の当該設置地点における事故予防警告発生状態の有無を判定し、事故予防警告発生状態が無ければスタートに戻り、事故予防警告発生状態があれば、ステップＳ８にてトラカン設置点から上流側の２ブロック（１ｋｍ区間）を点灯制御する。この場合、２ブロックを点灯制御している理由は、高速道路では上流側から侵入する車両の走行速度が速いので、交通の障害を発見したときの制動または待機距離を確保するため、トラカン設置点から上流側の２ブロックとしている。ここで、上流側とは車両の進行方向と逆方向側のことを指す。   Now, when the lighting / extinguishing control logic is activated, it is determined in step S7 whether or not an accident prevention warning has occurred at the installation location of the traffic measuring device (tracan). Returning, if there is an accident prevention warning occurrence state, the lighting control is performed on the two blocks (1 km section) upstream from the tracan installation point in step S8. In this case, the reason for controlling lighting of the two blocks is that the traveling speed of vehicles entering from the upstream side is high on the highway, so that a braking or standby distance when a traffic obstacle is found is secured. 2 blocks upstream. Here, the upstream side refers to the side opposite to the traveling direction of the vehicle.

図１において、例えばトラカン１ｂ設置点で交通の乱れが発生していれば、このトラカン１ｂ設置点から上流側の第１ブロック及び第２ブロックの自発光デリニェータ２ａ，２ｂを点灯制御すると同時に渋滞表示板３ａ，３ｂに対しても渋滞中であることを表示する。   In FIG. 1, for example, if traffic disturbance has occurred at the point where the tracan 1b is installed, the self-light-emitting delineators 2a and 2b of the first block and the second block upstream from the point where the tracan 1b is installed are controlled to light up at the same time. A message indicating that the traffic is being congested is also displayed on the boards 3a and 3b.

このような制御は制御処理部７で制御処理された情報を渋滞表示板制御部８、第１ブロック制御部９ａ及び第２ブロック制御部９ｂに与えることで、該当するブロックの自発光デリニェータ２ａ，２ｂが点灯制御されるとともに、渋滞表示板３ａ，３ｂが渋滞表示制御される。   Such control is performed by giving the information processed by the control processing unit 7 to the traffic congestion display board control unit 8, the first block control unit 9a, and the second block control unit 9b, so that the light-emitting delineator 2a of the corresponding block, The lighting control of 2b is performed, and the traffic congestion display plates 3a and 3b are controlled to display traffic congestion.

次にステップＳ９にてトラカン設置点、上記の例ではトラカン１ｂにおけるＸ分（１分）間の平均速度がＶ以上（Ｖ＝７０（ｋｍ／ｈ））であるか否かを判定し、Ｖ以上でなければステップＳ８に戻ってトラカン設置点から上流側の２ブロック（１ｋｍ区間）の点灯制御を継続する。   Next, in step S9, it is determined whether or not the average speed for X minutes (1 minute) in the trakan installation point, in the above example, in the tracan 1b is V or more (V = 70 (km / h)). If it is not above, it will return to step S8 and will continue lighting control of 2 blocks (1 km area) upstream from a trakan installation point.

また、ステップＳ９にて平均速度がＶ以上であると判定すると、ステップＳ１０にて点灯制御ブロックに対する他のトラカン設置点、上記の例ではトラカン１ｃにおけるＸ分（１分）間の平均速度がＶ以上（Ｖ＝７０（ｋｍ／ｈ））であるか否かを判定し、Ｖ以上でなければステップＳ８に戻ってトラカン設置点から上流側の２ブロック（１ｋｍ区間）の点灯制御を継続し、Ｖ以上であると判定するとステップＳ１１にて最小点灯単位ブロック毎に消灯制御する。   If it is determined in step S9 that the average speed is equal to or higher than V, in step S10, the other speed setting point for the lighting control block, that is, in the above example, the average speed for X minutes (1 minute) in the traffic can 1c is V. It is determined whether or not (V = 70 (km / h)), and if not V or more, the process returns to step S8 to continue the lighting control of the two blocks (1 km section) upstream from the tracan installation point. If it determines with it being V or more, it will perform light extinction control for every minimum lighting unit block in step S11.

上記の例では、トラカン１ｂ設置点で渋滞が発生して場合であるが、トラカン１ａ設置点で交通の乱れが発生している場合には、前述同様のロジック制御により第１ブロックのみの点灯制御が行われる。これはトラカン１ａの設置点より５００ｍ上流側を第１ブロックとしていることから、交通の乱れの発生地点から上流側の２ブロックに相当する距離（本例では１ｋｍ）があり、ドライバに注意を促す距離としては確保されるためである。   In the above example, there is a traffic jam at the point where the tracan 1b is installed. However, when traffic disruption occurs at the point where the tracan 1a is installed, only the first block is controlled by the same logic control as described above. Is done. This is because the first block is 500 m upstream from the installation point of Trakan 1a, so there is a distance (1 km in this example) equivalent to two blocks upstream from the point of traffic disturbance, and the driver is alerted This is because the distance is secured.

このように本実施形態では、交通の乱れが発生し易い箇所の道路に沿ってトラカン１ａ〜１ｄを５００ｍ間隔を存して設置し、また車両の進行方向から見て最初のトラカン１ａの設置点より５００ｍ後方のトラカン１ｂから５００ｍ間隔毎に第１乃至第４のブロックに分け、さらに各ブロックにそれぞれ設置された複数の自発光デリニェータ２ａ〜２ｄをそれぞれ設置する構成とし、かつ各トラカン１ａ〜１ｄで測定された通過車両の測定信号を検知部５ａ〜５ｄに入力して車両の通過台数及び通過速度を検知し、これらの検知部５ａ〜５ｄにより検知された通過車両の通過台数及び通過速度から事故予防警告発生判定部６の事故予防警告発生判定ロジックにより予め特定された交通の乱れの要因となる通過車両の通過台数及び通過速度により事故予防警告発生状態の有無を判定し、事故予防警告発生状態にあることが判定されると制御処理部７の点灯・消灯ロジックにより交通の乱れが発生している地点のトラカンから上流側の２ブロックの自発光デリニェータを点灯制御するようにしたものである。   As described above, in the present embodiment, the tracans 1a to 1d are installed at intervals of 500 m along a road where traffic disturbance is likely to occur, and the installation point of the first tracan 1a as viewed from the traveling direction of the vehicle. It is divided into the first to fourth blocks at intervals of 500 m from the tracan 1b behind 500m, and a plurality of self-luminous delineators 2a to 2d respectively installed in each block are installed, and each of the tracans 1a to 1d The measurement signal of the passing vehicle measured in step S5 is input to the detecting units 5a to 5d to detect the number of passing vehicles and the passing speed, and from the passing number and passing speed of the passing vehicles detected by these detecting units 5a to 5d. Depending on the number of passing vehicles and the passing speed that cause the traffic disturbance specified in advance by the accident prevention warning generation determination logic of the accident prevention warning generation determination unit 6 It is determined whether or not an accident prevention warning has occurred. If it is determined that an accident prevention warning has occurred, the control processing unit 7 is turned on / off logic to turn 2 The self-luminous delineator of the block is controlled to be turned on.

従って、事故の原因である交通の乱れの発生を速やかに判定し、上流側の車両に警告信号が発することにより、ドライバはそのことを踏まえて車両を運転することができるので、交通の流れの中での事故発生頻度を低減することができる。特に通過車両１台毎の過去１０秒以内の車両の平均速度が３０（ｋｍ／ｈ）を超え、かつ５０（ｋｍ／ｈ）以下のとき、事故予防警告発生状態と判定し、また０（ｋｍ／ｈ）を超え、かつ３０（ｋｍ／ｈ）以下のとき、渋滞が発生していると判定してその地点のトラカンから上流側の２ブロックの自発光デリニェータを点灯制御することで、追突や接触事故などの発生頻度の低減に寄与することができる。   Therefore, it is possible to promptly determine the occurrence of traffic disturbance that is the cause of the accident, and issue a warning signal to the upstream vehicle, so that the driver can drive the vehicle based on that, so traffic flow The frequency of accidents can be reduced. In particular, when the average speed of the vehicles within the past 10 seconds per passing vehicle exceeds 30 (km / h) and is 50 (km / h) or less, it is determined that an accident prevention warning has occurred, and 0 (km / H) and 30 (km / h) or less, it is determined that a traffic jam has occurred, and lighting control is performed on the self-luminous delineators of the two blocks upstream from the trakan at that point. This can contribute to a reduction in the frequency of contact accidents.

本発明は、交通の乱れが発生し易い道路であれば、高速道路ばかりでなく、一般道路のであっても前述同様に適用実施することができる。なお、一般道路の場合には事故予防警告発生判定ロジックでの判定として、交通の乱れが発生する要因を検証し、その結果をもとに車両の平均速度の判定基準を定める必要がある。   The present invention can be applied in the same manner as described above, not only on expressways, but also on general roads as long as traffic is likely to be disturbed. In the case of ordinary roads, it is necessary to verify the factors that cause traffic disturbance and to determine the criteria for determining the average speed of the vehicle based on the result as the determination by the accident prevention warning occurrence determination logic.
