本発明は、車両運転中の運転者が前を走行して
いる車両との車間距離を目測する際の目標物とな
る車間距離標示用道路標示構造に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a road for indicating distance between vehicles, which serves as a target when a driver is driving a vehicle and visually measures the distance between the vehicle and the vehicle traveling in front. Regarding marking structure.
一般に、高速道路を運転する場合には、万一の
追突事故発生を回避するために、自分の運転して
いる車両と前を走行している車両との車間距離を
常に目測し、安全車間距離を保つようにして運転
しなければならない。
In general, when driving on an expressway, in order to avoid a rear-end collision, always visually measure the distance between the vehicle you are driving and the vehicle in front, and keep a safe distance. You must drive in such a way as to maintain the
従来は、この車間距離の目測に供するために、
０ｍ、50ｍ、100ｍと書いた３種類の標示板を50
ｍおきに高速道路の路肩に設置して目測の目印と
し、更に、前記標示板の位置に合わせて車道表面
を横断する白線マーキングを塗布して同様に目測
の目印としている。 Conventionally, in order to visually measure this inter-vehicle distance,
50 of 3 types of signboards written 0m, 50m, 100m
They are placed on the shoulder of the expressway every m to serve as visual markers, and white line markings are applied across the road surface in accordance with the positions of the sign boards to serve as visual markers as well.
ところが、標示板においては高速運転を行なつ
ている運転者がそこに書かれている０ｍ、50ｍ、
100ｍ等の文字を前の車両との車間距離を目測し
つつ明確に識別することは困難であり、特に夜間
においては車のヘツドライトの照明のみにより照
らし出される文字と瞬時に識別するのはすこぶる
困難であり、結局正確な車間距離の把握が不可能
である。 However, on the signboards, drivers who are driving at high speeds are unable to follow the signs written on the signs such as 0m, 50m, etc.
It is difficult to clearly identify letters such as 100m while visually measuring the distance from the vehicle in front, and especially at night, it is extremely difficult to instantly distinguish them from letters illuminated only by the headlights of a car. Therefore, it is impossible to accurately determine the distance between vehicles.
一方、白色ペイント塗料を塗布して設けられた
白線マーキングは、交通量の多い高速道路におい

イントを塗布するものであるから、その度に交通
渋滞を起してしまうという不都合があつた。 On the other hand, white line markings provided by applying white paint are likely to be scratched off by tires and erased in a short period of time on expressways with heavy traffic. In addition, when the white line markings are reapplied, white paint is applied while marking one lane of the expressway as under construction and regulating traffic, which causes traffic congestion each time. I had the inconvenience of having to put it away.
本発明はこれらの点に鑑みてなされたものであ
り、高速運転中においても運転者に何ら負担をか
けることなく前を走行している車両との車間距離
を迅速かつ確実に目測して把握させることがで

り、所々に配設したりするとよい。 This embodiment is an example applied to an expressway 1 formed with three or more lanes, that is, four lanes on each side. This expressway 1 has an overtaking lane 3a, an inside lane 3b, and an outside lane 3c drawn on the road surface in order from the center separator 2 to the outside to divide the area up to the road shoulder 4 into four lanes. In this embodiment, markings 5a, 5b, and 5c, each consisting of a hollow three-dimensional figure of different height, are provided at intervals of 50 m for 100 m in the vehicle traveling direction (thick arrows in Figure 1) in the inner lane 3b. It is formed by To be more specific, the nearest 0
The sign 5a located at the m position is 40 cm high and colored red, and the sign 5b located at the middle 50 m position is 65 cm high and colored yellow.
The height of the sign 5c located at the farthest 100m position is
It is 80cm long and colored green. In FIG. 1, the length in the traveling direction is shorter than the actual length for convenience of drawing display. Each of the signs 5a, 5b, and 5c has a truncated conical pedestal 6 with a hollow pillar 7 made of rubber that can be restored even if stepped on by a vehicle, as shown in the sign 5a of FIG. 2, for example. The base 6 is removably fixed to the base 6 by bolts 8. A reflective sheet 9 is provided on the upper part of the hollow column 7.
Then, these three indicators 5a, 5b, 5c are
It is preferable to provide a plurality of sets consecutively in the running direction or to arrange them here and there.
次に、本実施例の作用を説明する。 Next, the operation of this embodiment will be explained.
一般に、高速道路を高速走行運転している運転

めに向けられる前方有効視野角度はほぼ20度と非
常に狭い。この狭視野角度において、運転者に何
らの負担をかけないで有効な車間距離目測用の目
印を提供するのはなかなか困難である。 In general, it is said that the effective forward viewing angle of a driver driving at high speed on a highway is approximately 40 degrees. Therefore, the effective forward viewing angle, which is used to visually measure the inter-vehicle distance by observing the markings on the road shoulder while keeping a close eye on the vehicle running in front, is very narrow, approximately 20 degrees. At this narrow viewing angle, it is difficult to provide an effective marker for measuring the distance between vehicles without placing any burden on the driver.
そこで、本実施例では運転者の前方有効視野内

に行なわせることができる。 Therefore, in this embodiment, each of the marking bodies 5a, 5b, and 5c is provided so that it naturally falls within the driver's effective front field of view and can serve as a landmark for measuring the distance between vehicles. In other words, each of the signs 5a, 5b, and 5c, whose height increases successively at 50 m intervals, can easily come into the driver's field of vision just by looking at the vehicle running in front of him. Since the height is perceived as a changing image that gradually increases as the vehicle advances, it functions as an effective landmark for measuring the distance between vehicles. Therefore, the driver does not use these signs 5a, 5b, and 5c to make judgments that require time and attention, such as reading letters, like in the past, day or night. , the distance between vehicles can be determined very easily, quickly and reliably. In addition, each sign body 5a, 5b,
Since the markings 5c are arranged in different colors, in combination with the difference in height, the function as a mark is enhanced, and furthermore, it is possible to easily grasp the distance between vehicles.
また、各標示体５ａ，５ｂ，５ｃは、万一車両
に踏まれても復元し、更に内側車線３ｂの道面上

を行なう必要がない。 In addition, each sign 5a, 5b, 5c can be restored even if it is stepped on by a vehicle, and is removably attached to the road surface of the inside lane 3b, so even if it is damaged, a new one can be installed. It is possible to easily reinstall the appropriate sign, and there is no need to carry out traffic regulations for a long period of time as in the past.
なお、各標示体５ａ，５ｂ，５ｃは内側車線３

体５ａ，５ｂ，５ｃを設けるとよい。 In addition, each sign 5a, 5b, 5c is on the inside lane 3.
It may be provided at a location other than b, for example, alone or in combination with the median strip 2 or the like. In addition, on roads where vehicles run in opposite directions across the center line without providing a center separator, it is preferable to provide each of the marking bodies 5a, 5b, and 5c on the center line.
また、標示体としては設置する道路の条件に応
じてその高さや形状や設置間隔等を適宜変更する
とよい。例えば、２車線の対向道路においては、
第３図に示すように、同図最左部から右方に向け

の65cmの標示体１０ｂを設け、55ｍから95ｍまで
の間に５ｍおきに同様に最も低い40cmの標示体１
０ａを配設し、100ｍ地点に最も高い80cmの標示
体１０ｃを設けて形成するとよい。この場合、標
示体１０ａ，１０ｂ，１０ｃが５ｍ間隔で連続的
に設けられているので、標示体の存在を運転者が
容易に認識することができ、車間距離の目測を容
易に行なうことができる。 Furthermore, the height, shape, installation interval, etc. of the markings may be changed as appropriate depending on the conditions of the road on which they are installed. For example, on a two-lane oncoming road,
As shown in Figure 3, from the leftmost part of the figure to the right, the lowest 40
A 65cm high marker 10b is placed at the 50m point, and the lowest 40cm marker 1 is placed every 5m from 55m to 95m.
0a and the highest sign 10c of 80cm at the 100m point. In this case, since the signs 10a, 10b, and 10c are consecutively provided at 5 m intervals, the driver can easily recognize the presence of the signs and easily measure the distance between vehicles. .
また、第４図に示すように、道路鋲１１ａを適
当間隔に配設し、50ｍ地点と100ｍ地点とにそれ
ぞれ高さが順に高くなる標示体１１ｂ，１１ｃを
設けて形成してもよい。 Alternatively, as shown in FIG. 4, road studs 11a may be arranged at appropriate intervals, and markings 11b and 11c whose heights increase in order may be provided at 50 m points and 100 m points, respectively.
