【0001】 [0001]

【発明の属する技術分野】本発明は、道路工事等に用いて交通を片側通行規制する、仮設信号システムに関するものである。 BACKGROUND OF THE INVENTION The present invention is directed to one side traffic regulation traffic used in road construction, etc., to a temporary signal system.

【0002】 [0002]

【従来の技術】道路工事現場、事故現場等において、複数の信号機を用いて交通を片側通行規制する仮設信号システムが用いられている。 BACKGROUND OF THE INVENTION road construction site, at the accident site, etc., temporary signal system to one side traffic regulation traffic by using a plurality of signal is used. この仮設信号システムは、交通規制区間の出入り口等に信号機をそれぞれ仮設して、 The temporary signal system, and temporary each traffic signal on entrance or the like of the traffic control section,
赤信号灯や青信号灯等の信号灯を切り替えて信号を表示することにより、一方の方向の車両等を停止すると共に他方の方向の車両等を通行させた後、その他方の方向の車両等を停止すると共に一方の方向の車両等を通行させる規制を繰り返し、片側通行規制するようになっている。 By displaying the signal by switching a signal light such as red light or green light lights, after passing the other direction of the vehicle such as to stop the vehicle or the like in one direction, stops its other direction of the vehicle, etc. Repeat regulations for passing vehicles or the like in one direction with, adapted to one traffic regulation. そして一般には、各信号機間の点灯の同期をとりながら、予め設定された時間間隔で赤信号灯と青信号灯の表示を交互に繰り返し、交通を規制するようになっている。 And generally, while synchronizing the lighting between the traffic signal, alternately repeating the display of the red light and green light lamp at a preset time interval, so as to regulate the traffic.

【0003】しかしこのような予め設定された時間間隔で赤信号灯と青信号灯の表示を切り替える仮設信号システムを用いた場合、時間帯により交通の流れが大きく変わる場所等は、一方の方向の車線の流れは円滑に流れるが、他方の方向の車線の流れは交通渋滞を招くというように、全体の交通の流れのバランスが取れにくいという問題があった。 However when using a temporary signaling system for switching the display of the red light and green light lights in such a preset time interval, places like traffic flow largely changes with time zone in one direction of the lane flow flows smoothly, but the other direction of the lane of the flow so that lead to traffic congestion, there is a problem that it is difficult balance the overall traffic flow.

【0004】そのため、例えば、特開平5−15919 [0004] Therefore, for example, JP-A-5-15919

【0005】しかし、特開平5−159197号に示されるような仮設信号システムの場合、車両の大きさや通行速度によって、一定時間に通過できる台数が変わりやすいため、実際に赤信号によって停車している車両台数と差が生じやすいという問題があり、特に2輪車が含まれる場合差が生じやすいという問題があった。 However, in the case of temporary signal system as shown in Japanese Patent Laid-Open No. 5-159197, depending on the size and passage speed of a vehicle, and is easy to change the number that can pass a given time, it is stopped by actually red light There is a problem that the number of vehicles and the difference is likely to occur, there is a problem that if the difference is likely to occur particularly includes two-wheeled vehicle. また、特開平7−21490号に示されるような仮設信号システムの場合、待ち台数が予め設定した許容待ち台数未満の場合は調整されず、かつ、その予め設定した許容待ち台数は通行量の多いときを基準に一般に設定されているため、通行量が少ない場合は、全体の交通の流れのバランスが取れにくいという問題があった。 Also, in the case of temporary signal system as it is shown in Japanese Patent Laid-Open No. 7-21490, if it is less than the allowable waiting number of wait number is preset not adjusted, and the allowable waiting number set a previously busy traffic volume since it is generally set based on time, when traffic volume is small, there is a problem that it is difficult balance the overall traffic flow.

【0006】そのため、信号灯を有する信号機を交通規制区間の入り口部にそれぞれ設け、各信号機の信号灯の点灯を制御して交通を規制する仮設信号システムであって、双方向の車線の通行量に差がある場合であっても、 [0006] Therefore, provided each traffic signal having a signal lamp at the entrance portion of the traffic control section, a temporary signaling system for regulating traffic by controlling the lighting of signal lamp of each traffic signal, a difference in traffic volume of bidirectional lanes even if there is,
全体の交通の流れのバランスが取りやすく、安定した片側通行規制を可能とする仮設信号システムが求められている。 Overall traffic tends to take the balance of flow, temporary signaling system that allows a stable one traffic regulation is required.

【0007】 [0007]

【発明の実施の形態】本発明に係る仮設信号システムを図面に基づいて説明する。 It will be described with reference to temporary signal system according to the embodiment of the present invention in the drawings. 図1は本発明の請求項1に係る仮設信号システムの一実施の形態を説明する図であり、図2は本発明の請求項4に係る仮設信号システムの一実施の形態を説明する図である。 Figure 1 is a diagram illustrating an embodiment of a temporary signaling system according to claim 1 of the present invention, FIG 2 is a diagram illustrating an embodiment of a temporary signal system according to claim 4 of the present invention is there.

【0015】本発明の請求項1に係る仮設信号システムの一実施の形態は、図1に示すように、赤信号灯11及び青信号灯12を備えた信号機1a,1bを交通規制区間4の入り口部の停止線3,3の付近にそれぞれ設け、 [0015] One embodiment of the temporary signaling system according to claim 1 of the present invention, as shown in FIG. 1, the inlet portion of the red signal lamp 11 and the traffic signal 1a, 1b traffic control section 4 having the green light lamp 12 provided each near the stop line 3,3,
各信号機1a,1bの信号灯(11,12)の点灯を制御して交通を片側通行規制する仮設信号システムである。 Each traffic signal 1a, a 1b temporary signal system signal lamp traffic by controlling the lighting of (11, 12) to one side traffic regulations. そして、その信号機1a,1bにより停車する車両2のうち、最も交通規制区間4に近い車両2の停止時間を検出する停止時間検出手段13を各信号機1a,1b Then, the traffic signal 1a, of the vehicle 2 stops by 1b, the most traffic control section stop time for detecting the stop time near the vehicle 2 to 4 detecting means 13 of each traffic signal 1a, 1b
に備えると共に、各信号機1a,1bの停止時間検出手段13と接続した制御手段(図示せず)を一方の信号機1aに備えている。 Together provided the includes the traffic signal 1a, a control means connected with the stop time detecting means 13 1b (not shown) to one of the traffic signal 1a.

【0016】そして、制御手段において、各信号機1 [0016] Then, the control means, each traffic signal 1
a,1bの停止時間検出手段13が、それぞれ所定時間中に検出した車両の停止時間pと、上記所定時間中に赤信号灯を点灯した時間qを用いて、下記式(a)で表される車両停止時間率rを各信号機1a,1b毎に求めるようになっている。 a, stop time detecting means 13 1b, using the vehicle downtime p detected during a predetermined time, respectively, a red lamp lit time q during the predetermined time, represented by the following formula (a) vehicle stop time rate r each traffic signal 1a, which is to seek for each 1b. r=p/q ・・・(a) r = p / q ··· (a)

【0017】なお、車両の停止時間pを検出する所定の時間は、いずれかの信号機1aの青信号灯12が点灯を開始してから、その信号機1aの次のサイクルの青信号灯12が点灯を開始するまでの間の点灯1サイクルの時間以上であれば特に限定するものではないが、その数倍の点灯数サイクルの時間であると、車両2の通行量を平均化したデータが得られるため好ましい。 [0017] Incidentally, the predetermined time for detecting the stop time p of the vehicle, from the green signal lamp 12 starts lighting of one of the traffic 1a, starting blue signal lamp 12 is lit for the next cycle of the traffic signal 1a It is not particularly limited as long as the lighting time of one cycle or more until the, if it is time for several times of the lighting cycles, preferably for averaged data traffic amount of the vehicle 2 is obtained . なお、複数のサイクルに渡る時間で検出する場合には、それぞれのサイクルにおいて検出した、最も交通規制区間4に近い車両2の停止時間の合計と、その複数のサイクルにおける赤信号灯を点灯した時間の合計を用いて車両停止時間率を求める。 In the case of detecting a time over a plurality of cycles was detected in each cycle, the most traffic regulation section downtime vehicle 2 close to 4 sum, the time that light the red lamp in the plurality of cycles Request vehicle stop time rate using the total. なお、5サイクル以上の時間で検出する場合には、中間で開始及び終了したサイクルの影響は小さくなるため、サイクルの区切りで開始及び終了しなくてもよい。 In the case of detecting by 5 or more cycles of time, because the smaller the start and effects of the terminated cycles in the middle, may not start and end with delimiters cycle.

【0018】次いで、制御手段において、その各信号機1a,1b毎の車両停止時間率r1,r2と青信号灯1 [0018] Then, the control means, each traffic signal 1a, a vehicle stop time rate per 1b r1, r2 and blue signal lamp 1

青信号灯12を点灯する時間s1,s2を調整するようになっている。 And adjusts the time s1, s2 to light the green light lamp 12. r1:s1=r2:s2 ・・・(b) r1: s1 = r2: s2 ··· (b)

【0019】なおこの調整する方法としては、上記式(b)を変形することにより、例えば、一方の信号機1 [0019] Note that as a method of this adjustment, by modifying the above formula (b), for example, one of the traffic 1
aの新たな青信号灯12を点灯する時間s1は、下記式(c)で表す式で計算されるようになっている。 Time s1 to light the new green light lamp 12 a is adapted to be calculated by the formula expressed by the following formula (c). s1=(r1/r2)×s2 ・・・(c) s1 = (r1 / r2) × s2 ··· (c)

【0020】なおこのとき、一方の信号機1aの青信号灯12が消灯してから他方の信号機1bの青信号灯12 [0020] At this time, the blue signal lamp 12 of the other traffic 1b from green signal lamp 12 of one of the traffic signal 1a is turned off
が点灯するまでの間の、双方向共に赤信号灯11が点灯する時間は、変更しないことが好ましい。 There between until the lighting time of a red signal lamp 11 is turned in both directions both are preferably not changed. また、青信号灯12を点灯する時間s1,s2の最短値を決めておき、上記式(c)等で計算した値がその最短値未満の場合には、各信号機1a,1bの青信号灯12の点灯する時間s1,s2の比率は変えずにその点灯する時間s Further, the time s1, s2 to light the green light lamp 12 in advance to decide the shortest value, in the case of less than the above formula (c) is a value calculated in such that the shortest value, the traffic signal 1a, 1b of the blue signal lamp 12 time to light s1, s2 time s the ratio is the lighting without changing the
1,s2を長くしてして最短値に合わせるようにすると、通行量の少ない車線の流れが安定して好ましい。 1, when so adjusted to the s2 to be made longer minimum value, preferably stable flow of traffic amount less lane. また、上記点灯1サイクルの長さの最長値を決めておき、 Alternatively, it is acceptable to determine the maximum value of the length of the lighting cycle,
上記式(c)等で計算した点灯1サイクルの長さがその最長値を越える場合には、各信号機1a,1bの青信号灯12の点灯する時間s1,s2の比率は変えずにその点灯する時間s1,s2を短くしてもよい。 If the length of a lighting cycle calculated by the above formula (c) or the like exceeds the maximum value, the traffic signal 1a, the ratio of the lighting time-s1, s2 of the blue signal lamp 12 of 1b is its lighting without changing it may be to shorten the time s1, s2.

【0021】このように、その信号機1a,1bにより停車する車両2のうち、最も交通規制区間4に近い車両2の停止時間を用いて青信号灯12を点灯する時間s [0021] Thus, the traffic signal 1a, of the vehicle 2 stops by 1b, time to light the green light lamp 12 with the most traffic regulation section downtime vehicle 2 close to 4 s
1,s2を調整するようにしているため、車両の大きさや通行速度による影響を受けず、また、通行量の多い車線の青信号灯12が点灯する時間s1を長くするように調整するため、双方向の車線の通行量に差がある場合であっても、全体の交通の流れのバランスが取りやすく、 1, s2 because you have to adjust the unaffected by the size and passage speed of a vehicle, also for traffic intensive lane green signal lamp 12 is adjusted to increase the time s1 to light, both even if there is a difference between the traffic amount of direction of the lane, it tends to balance the overall traffic flow,
安定した片側通行規制が可能となる。 Stable one-sided traffic regulation is possible. また、通行量が少ない場合と通行量が多い場合で、同じ方法で制御が可能なため、制御手段の構造が簡単な構造でよいという効果も得られる。 In the case when traffic volume is small and traffic amount is large, because it can be controlled in the same way, there is also an effect that the structure of the control means may be a simple structure.

【0022】なお、この仮設信号システムに、全ての信号機1a,1bの車両停止時間率r1,r2が、予め設定された値以下の場合に、各信号機の信号灯の点灯を、 [0022] Note that, in this temporary signal system, all traffic lights 1a, a vehicle stop time rate r1, r2 of 1b is, in the case of lower than or equal to the preset value, the lighting of a signal lamp for each traffic signal,
赤信号灯の点滅動作に変更する点滅手段を備えていてもよい。 It may comprise a blinking means for changing the blinking of the red light lamp. その場合、夜間等、特に通行量が少ない時には点滅動作となるため、通行量が少ない時に赤信号灯11で停車することが少なくなり、交通の流れが更に良好となり好ましい。 In that case, such as nighttime, because of particular blinking when a small traffic amount, it is less to stop at a red light lamp 11 when a small traffic amount, traffic flow is preferably become even better. なお、この赤信号灯の点滅動作に変更する予め設定された値は、特に限定するものではなく、夜間等の通行量より適宜設定すればよい。 Incidentally, a preset value is changed to blinking of the red signal lamp is not particularly limited, it may be appropriately set from the traffic amount such as at night.
