Abstract

<P>PROBLEM TO BE SOLVED: To provide a method for identifying a violation vehicle without holding sufficient vehicle following distance by a simple operation from a police car under high speed travel and for enhancing its admissibility. <P>SOLUTION: The police car A on which a violation evidence creating device in which a laser distance measuring function and a photographic image acquiring function are incorporated is mounted irradiates a laser beam on a rear part of a forward vehicle C obliquely from behind a suspected vehicle B without having the vehicle following distance by using a laser distance measuring device, measures a distance, simultaneously takes its state photograph with an electronically interlocked CCD camera and defines it as an evidence photograph. Three vehicles as a front part of the police car A, the suspected vehicle B without holding the vehicle following distance and the front vehicle C are portrayed in one photograph, positional relation among the three vehicles is clearly read and a fact that the police car is not in front of the suspected vehicle is proved. Namely, a measurement value N is larger than the vehicle following distance L between the front part of the suspected vehicle and the rear part of the front vehicle and, when the measurement value N is shorter than violation distance, L is also violated. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

【0001】
【産業上の利用分野】
本発明は高速道路などの道路上において、前走車両に対して追走車両が接近して車間距離保持不足による交通違反を為した時の違反車両状況を証拠として示す測定法に関する。
【0002】
【従来の技術】
警察庁の発表によると高速道路での事故の約半分は車間距離保持不足車両によるもので、車間距離保持不足の指導、取り締まりをすれば事故を未然に防げる。
従来の車車間距離保持不足車両の取り締まりは車両区分線を活用した、警察官の目測によるものが主流で行われていた。白線は8m、次の白線まで12m合わせて20mあり、その比較で車間距離を数値化し、車間距離保持不足指導、取り締まり資料として用いられていた。
【0003】
高速運転中に目測で測定するたるめ、誤差も多く又、得られた数値は客観性に欠く人為的なものであるてめ、車間距離保持不足車両の違反者に対して、説得力に欠く証拠となっていた。
【0004】
そこで本発明者は先にレーザー光線とCCDカメラを用いた車間距離保持不足違反の違反証拠作成システムと車間距離測定方法、特願平10−283527を提案し解決を図った。この発明は被疑車両(B)の前頭部と前走車両(C)の後部間の距離を測定する方法で、同時二方向のレーザー距離計と角度計の組合せによるものと、一方向レーザー距離計と赤外線センサーを組合せたものであった。
【0005】
【発明が解決しようとする課題】
同時二方向の距離計で測定するものは高速走行中に前走車両(C)後部と被疑車両(B)前頭部を同時に観測し、測定しなければならないため、熟練を要した。又、一方向の距離計で測定するものは予めパトカーと被疑車両との間隔を数値化しておくため、走行中に数値化設定しておいた距離に合うまで被疑車両(B)に接近し、あわせる必要があり、高度な運転技術が必要とされた。
【0006】
更に、ハード面では角度計や感知センサーも必要で嵩張り、又、ソフト面でもコントロールソフトが複雑となり、操作の簡易化及びコストの削減が望まれていた。
【0007】
【課題を解決するための手段】
車間距離保持不足車両の取り締まり基準は道路交通法第26条の規定に基づいて運用されている。道路交通法第26条は「車両等は、同一進路を進行している他の車両等の直後を進行するときは、その直前の車両が急に停車したときにおいてもこれに追従するのを避けることができるための必要な距離を、保たねばならない。」と謳っている。
【0008】
高速道路における取締り運用にあたっては上記条文の「その直前の車両が急に停車したときにおいても、これに追従するのを避けることができるための必要な距離」を保っているか、いないかを確認する方法をとっている。
その距離の判断基準としては次の算式による。
最小車間距離=自動車の速度×後続車運転者の空走時間
ここで、空走時間は反射時間+踏み変え時間+踏み込み時間とし、最高裁の「車間距離に関する鑑定例」によれば、空走時間の平均値を1.20秒と鑑定している。
【0009】
例えば100km/hでは33.336mとなり、高速道路における適正車間距離不保持の危険性を考えるとき少なくとも100Km/hで30mの車間距離を保持していない車両が危険で取り締まりの対象とすべきである。とされている。車間距離不保持車両の取り締まりは速度に応じた必要車間距離が保たれているか、いないかを確定できる測定方法であれば良い。
【0010】
そこで、被疑車両(B)の前頭部と前走車両(C)の後部間の距離を直接測らず、パトカーの測定位置から前走車両までの距離を測り、その時、被疑車両はパトカーより前に位置していることが判り、測定した距離値が車間距離保持不足しているか、いないかを判断できる測定方法を提案する。
【0011】
レーザー距離測定機能及び写真画像取得機能が組みこまれた違反証拠作成装置(S)を搭載したパトカー(A)はレーザー距離測定機を用いて、車間距離不保持被疑車両(B)の斜め後方より前走車両(C)の後部へレーザー光線を照射し、距離を測定すると同時に、電子的に連動しているCCDカメラでその状況写真を撮影する。この1枚の写真にはパトカー(A)の前頭部と車間距離不保持被疑車両(B)と前走車両(C)の三台の車両が写し出される。この状況写真からパトーカーは被疑車両より前に出ていないことが判る。図2
【0012】
図1で説明するとパトカーから測定した距離Nは被疑車両と前走車両との車間距離Lより長いことが判る。この時、測定値Nが違反値より短ければ、車間距離Lは更に短いため、違反していることが証明され、確定できる。
【0013】
【発明の実施の形態】
本発明は本発明者が先に提案している車間距離保持不足違反の違反証拠作成システムとその距離測定方法、特願平10−283527の違反証拠作成装置(S)を用いて、車間距離保持不足状況を証明する測定方法である。
本発明を図1で説明すると、レーザー距離測定機能及び写真画像取得機能が組みこまれた違反証拠作成装置(S)を搭載したパトカー(A)はレーザー距離測定機を用いて、車間距離不保持被疑車両(B)の斜め後方より、前走車両(C)の後部へレーザー光線を照射し、距離を測定すると同時に、電子的に連動しているCCDカメラでその状況写真を撮影する。写真画像には前走車両(C)へレーザー光線照射をしたポイントを示す、表示マークが表示される。
これらのデータと速度、時刻、GPSによる緯度経度値から算出した所在地等がメモリーカードに記憶され、プログラム化された所定様式の違反切符に(K)に出力される。
【0014】
【実施例】
高速道路をパトロール中に車間距離不保持被疑車両(B)を発見した場合(図1)被疑車両を追尾し、被疑車両(B)の斜め後ろまで接近する。そして違反証拠作成装置(S)のレーザー距離計を用いて前走車両(C)の後部へレーザーを照射し、パトカーのレーザー測定機から前走車両の後部までの距離Nを測る。この時同時に自動的に状況写真図2が撮影される。
【0015】
この図から測定距離Nは測定機から被疑車両の先端部P+車間距離Lより更に斜距離となり、長いことが判る。
P+L=NcosQ
L=NcosQ−P
つまり被疑車両の車間距離Lは常にNより短い。ここで測定値Nが違反距離より短い値なら当然車間距離Lも違反している。
【0016】
パトカーが被疑車両より前で測定すれば、写真に被疑車両が写らず、パトカーと前走車両の2台だけが写っているためこの時のデータは使えない。指導取締りは必ず関係車両3台が写っていなければならない。
【0017】
【発明の効果】
本発明は上記のとおり、高速走行中のパトカーの車中から、違反証拠作成装置(S)の距離計のトリガーを引くだけで、車間距離不保持車両違反の証拠を残すことができるため、熟練も要さず、操作も簡単に車間距離不保持車両違反車両を取り締まることができる。
【0018】
違反証拠作成装置(S)も角度計や赤外線センサーなどの付属品が不用となり、小型化できる。又、機器をコントロールするソフトも簡素化することができ、大幅なコストダウンを図れ、経済効果を出すことができる。

[Industrial applications]
The present invention relates to a measurement method for showing, as evidence, a violating vehicle situation when a following vehicle approaches a preceding vehicle on a road such as an expressway and causes a traffic violation due to insufficient inter-vehicle distance maintenance.
[0002]
[Prior art]
According to the National Police Agency, about half of accidents on expressways are caused by vehicles with insufficient inter-vehicle distance. Guidance and enforcement of insufficient inter-vehicle distance can prevent the accident.
In the past, crackdowns on vehicles with insufficient vehicle-to-vehicle distance were mainly performed by police officers using vehicle lane markings. The white line is 8m and the next white line is 12m, which is 20m in total. By comparing the distances, the inter-vehicle distance is quantified and used as guidance for the insufficiency of inter-vehicle distance maintenance and as a control document.
[0003]
There is a lot of sagging and error in measurement during high speed driving, and the obtained value is artificial due to lack of objectivity. It was proof.
[0004]
The inventor of the present invention has previously proposed and solved the violation evidence creating system and the method for measuring the distance between vehicles using a laser beam and a CCD camera. The present invention is a method for measuring the distance between the front of the suspect vehicle (B) and the rear part of the preceding vehicle (C). It was a combination of a meter and an infrared sensor.
[0005]
[Problems to be solved by the invention]
In the case of measuring with a simultaneous two-way distance meter, it is necessary to observe and measure the rear part of the front vehicle (C) and the front part of the suspect vehicle (B) at the same time during high-speed traveling. In addition, in order to measure the distance between the police car and the suspected vehicle in advance by using a one-way distance meter, the vehicle approaches the suspected vehicle (B) until the vehicle reaches the distance set in the numerical value during traveling. They needed to be matched, and advanced driving skills were needed.
[0006]
Further, a hard surface requires a goniometer and a sensing sensor, which is bulky, and a soft surface requires complicated control software, so that simplification of operation and cost reduction have been desired.
[0007]
[Means for Solving the Problems]
Regulations on the control of vehicles with insufficient inter-vehicle distance are operated based on the provisions of Article 26 of the Road Traffic Act. Article 26 of the Road Traffic Law states, "When a vehicle travels immediately after another vehicle traveling on the same course, avoid following the vehicle immediately before it stops suddenly. You have to keep the distance you need to be able to do it. "
[0008]
In the enforcement operation on expressways, make sure that the above-mentioned provisions maintain "the necessary distance to avoid following the vehicle even if it stops suddenly immediately". Is taking the method.
The following formula is used to determine the distance.
Minimum inter-vehicle distance = car speed x idle running time of the following vehicle driver Here, the idle running time is defined as reflection time + step change time + stepping time, and according to the Supreme Court's "Example of Inter-Vehicle Distance Appraisal", idle running The average value of the time is determined to be 1.20 seconds.
[0009]
For example, at 100 km / h, the distance is 33.336 m. Considering the danger of not maintaining an appropriate inter-vehicle distance on a highway, vehicles that do not maintain an inter-vehicle distance of at least 100 km / h and 30 m should be subject to risk control. . It has been. The control of the vehicle that does not maintain the inter-vehicle distance may be any measurement method that can determine whether the required inter-vehicle distance according to the speed is maintained or not.
[0010]
Therefore, instead of directly measuring the distance between the front of the suspected vehicle (B) and the rear part of the preceding vehicle (C), the distance from the position where the police car was measured to the preceding vehicle was measured. And proposes a measurement method that can determine whether the measured distance value is insufficiently maintained or not.
[0011]
A police car (A) equipped with a violation evidence creation device (S) incorporating a laser distance measurement function and a photographic image acquisition function uses a laser distance measurement device from an oblique rear of the suspect vehicle (B) that does not maintain the following distance. The rear part of the preceding vehicle (C) is irradiated with a laser beam to measure the distance and, at the same time, photograph a picture of the situation with a CCD camera that is electronically linked. In this one photograph, three vehicles, the front head of the police car (A), the vehicle (B) suspected of not maintaining the inter-vehicle distance, and the preceding vehicle (C) are shown. This photograph shows that the patrol car is not in front of the suspect vehicle. FIG.
[0012]
Referring to FIG. 1, it can be seen that the distance N measured from the police car is longer than the inter-vehicle distance L between the suspected vehicle and the preceding vehicle. At this time, if the measured value N is shorter than the violation value, the inter-vehicle distance L is further shorter, and it is proved that the vehicle violates and can be determined.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention uses a violation evidence creation system and a distance measurement method for the violation of insufficient distance between vehicles proposed by the present inventor, and a violation evidence creation device (S) of Japanese Patent Application No. 10-283527 to maintain the distance between vehicles. This is a measurement method to prove the shortage situation.
The present invention will be described with reference to FIG. 1. A police car (A) equipped with a violation evidence creating device (S) incorporating a laser distance measuring function and a photographic image acquiring function uses a laser distance measuring machine to maintain a distance between vehicles. A laser beam is applied to the rear part of the preceding vehicle (C) from obliquely behind the suspect vehicle (B) to measure the distance and, at the same time, photograph a picture of the situation with a CCD camera that is electronically linked. In the photographic image, a display mark indicating a point at which the preceding vehicle (C) is irradiated with the laser beam is displayed.
The data, the speed, the time, the location calculated from the latitude and longitude values by GPS, and the like are stored in a memory card and output to a programmed ticket in a predetermined form (K).
[0014]
【Example】
If the suspected vehicle (B) is found while patroling the highway (FIG. 1), the suspected vehicle is tracked and approached diagonally behind the suspected vehicle (B). Then, the laser is applied to the rear part of the preceding vehicle (C) using the laser distance meter of the violation evidence creating device (S), and the distance N from the laser measuring machine of the police car to the rear part of the preceding vehicle is measured. At this time, the situation photograph FIG. 2 is automatically taken at the same time.
[0015]
From this figure, it can be seen that the measuring distance N is longer than the tip P of the suspected vehicle and the inter-vehicle distance L from the measuring instrument and is longer.
P + L = NcosQ
L = NcosQ-P
That is, the inter-vehicle distance L of the suspect vehicle is always shorter than N. Here, if the measured value N is shorter than the violation distance, the inter-vehicle distance L naturally violates.
[0016]
If the police car is measured before the suspected vehicle, the data at this time cannot be used because the photograph does not show the suspected vehicle but only the police car and the preceding vehicle. Guidance and enforcement must include three related vehicles.
[0017]
【The invention's effect】
As described above, according to the present invention, only by pulling the trigger of the range finder of the violation evidence creating device (S) from the patrol car traveling at high speed, it is possible to leave evidence of the violation of the vehicle that does not maintain the following distance, and It is not necessary, and the operation can be easily performed to control the vehicle violating the vehicle that does not maintain the following distance.
[0018]
The violation evidence creation device (S) does not require accessories such as a goniometer and an infrared sensor, and can be downsized. Also, the software for controlling the equipment can be simplified, so that the cost can be significantly reduced and the economic effect can be obtained.
