Abstract

PROBLEM TO BE SOLVED: To provide a reverse running information notification system for promptly transmitting existence of a reverse running vehicle to a peripheral vehicle.SOLUTION: An on-road machine 100 having reverse running detection means 101 for detecting a reverse running vehicle delivers an instruction on a transmission request of reverse running information to notify a peripheral vehicle of existence of the detected reverse running vehicle via a communication network. An on-road machine 300 arranged in a traveling direction of the reverse running vehicle receives the instruction from the on-road machine 100, and requests transmission of the reverse running information by radio to a peripheral vehicle 400 traveling on the opposite lane of the reverse running vehicle. The vehicle 400 that receives the transmission request transmits the reverse running information by radio to a vehicle traveling on the same lane of the reverse running vehicle. The on-road machine 100 includes reverse running information transmission request determination means 110 for selecting the on-road machine 300 as an on-road machine being an instruction destination of a transmission request of reverse running information.SELECTED DRAWING: Figure 1

Description

この発明は、移動体の逆走行を検出し、通知する逆走情報通知システムに関するものである。   The present invention relates to a reverse running information notification system that detects and notifies reverse running of a moving body.

特許文献１の従来の逆走情報通知システムの構成動作は以下のとおりである。
第１路側無線装置は、通信可能範囲を通過する車両に対して、この車両が有料道路に進入したことを示す入口ゲート通過情報を付与する。この第１路側無線装置は、有料道路の流入ランプに設けられる。
一方、第２路側無線装置は、通信可能範囲を通過する車両から第１路側無線装置によって付与された入口ゲート通過情報を取得する。第２路側無線装置は、有料道路の流出ランプに設けられる。そして、管理装置としての機能を有する第２路側無線装置は、通過車両から入口ゲート通過情報が取得されたか否かを判定し、この入口ゲート通過情報が取得されない場合には、その車両に逆走していることを警告する逆走警告情報を提供する。
有料道路等の一方通行路を逆走する可能性が極めて高い車両がある場合に、その逆走車両および本線を走行中の車両に対して、警告または注意を行う。 The configuration operation of the conventional reverse running information notification system of Patent Document 1 is as follows.
The first roadside wireless device gives entrance gate passage information indicating that the vehicle has entered the toll road to the vehicle passing through the communicable range. The first roadside wireless device is provided on the inflow ramp of the toll road.
On the other hand, the second roadside apparatus acquires the entrance gate passage information given by the first roadside apparatus from the vehicle passing through the communicable range. The second roadside wireless device is provided on the outflow ramp of the toll road. Then, the second roadside apparatus having a function as a management apparatus determines whether or not the entrance gate passage information is acquired from the passing vehicle. If the entrance gate passage information is not acquired, the second roadside wireless device reversely travels to the vehicle. Provides reverse running warning information to warn you that
When there is a vehicle that is extremely likely to run backward on a one-way street such as a toll road, a warning or caution is given to the backward running vehicle and the vehicle traveling on the main line.

国際公開第２００９／０８１８１７号（第７〜１０頁、第４図）International Publication No. 2009/081817 (7th to 10th pages, Fig. 4)

しかしながら、有料道路に設置された第２路側無線装置が、有料道路等の一方通行路を逆走する可能性が極めて高い車両が逆走行していることを認識した場合、逆走車の存在を示す情報（以後「逆走情報」と呼ぶ）を通知する表示装置の設置数の少ない地域では、逆走情報を取得できる機会が少ないという問題がある。
また、逆走車自身から無線通信により逆走情報を通知する場合、逆走車に接近して通信圏内に入らなければ情報を取得できないという問題もある。
どちらの場合も、逆走情報を取得してから回避行動をとるために要する時間が十分に確保できない恐れがある。 However, if the second roadside wireless device installed on the toll road recognizes that a vehicle that is extremely likely to run backward on a one-way road such as a toll road is running backwards, In an area where the number of display devices that notify the information to be displayed (hereinafter referred to as “reverse running information”) is small, there is a problem that there is little opportunity to obtain reverse running information.
In addition, when notifying the reverse running information by wireless communication from the reverse running vehicle itself, there is also a problem that the information cannot be acquired unless the reverse running vehicle is approached and enters the communication range.
In either case, there is a possibility that the time required for taking the avoidance action after acquiring the reverse running information cannot be secured sufficiently.

この発明は、上述のような課題を解決するためになされたものであり、逆走車の存在を早期に周辺車両に伝達できる逆走情報通知システムを得ること目的とする。   The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a reverse running information notification system capable of quickly transmitting the existence of a reverse running vehicle to surrounding vehicles.

この発明に係わる逆走情報通知システムにおいては、逆走車を検知し、この検知した逆走車の存在を周囲の車両に知らせるための逆走情報の送信要請を、通信網を介して指示する第一の路上機、および逆走車の進行方向に設置され、第一の路上機からの指示を受けて、逆走車の対向車線を走行する車両に対して、無線により逆走情報の送信要請を行なう第二の路上機を備え、第二の路上機からの送信要請を受けた車両は、逆走車と同じ車線を走行する車両に対し、無線により逆走情報を送信するものである。   In the reverse running information notification system according to the present invention, a reverse running vehicle is detected, and a transmission request for reverse running information for notifying the surrounding vehicles of the presence of the detected reverse running vehicle is instructed via a communication network. Transmission of reverse running information wirelessly to vehicles traveling in the opposite lane of the reverse running vehicle in response to an instruction from the first roadside device and in the direction of travel of the first roadside vehicle and reverse running vehicle A vehicle having a second road machine for making a request and receiving a transmission request from the second road machine transmits reverse running information wirelessly to a vehicle traveling in the same lane as the reverse running vehicle. .

この発明によれば、逆走車を検知し、この検知した逆走車の存在を周囲の車両に知らせるための逆走情報の送信要請を、通信網を介して指示する第一の路上機、および逆走車の進行方向に設置され、第一の路上機からの指示を受けて、逆走車の対向車線を走行する車
両に対して、無線により逆走情報の送信要請を行なう第二の路上機を備え、第二の路上機からの送信要請を受けた車両は、逆走車と同じ車線を走行する車両に対し、無線により逆走情報を送信するので、逆走車の存在を、衝突の危険のある車両に早期に伝達することができる。 According to the present invention, a first road machine that detects a reverse running vehicle and instructs a transmission request of reverse running information for notifying the surrounding vehicles of the presence of the detected reverse running vehicle via a communication network, A second vehicle that is installed in the direction of travel of the reverse running vehicle, receives a command from the first road machine, and makes a transmission request for reverse running information wirelessly to a vehicle traveling in the opposite lane of the reverse running vehicle A vehicle equipped with a road machine and receiving a transmission request from the second road machine transmits the reverse running information wirelessly to the vehicle traveling in the same lane as the reverse running vehicle. It can be transmitted early to vehicles at risk of collision.

実施の形態１．
実施の形態１は、逆走車を検知した第一の路上機が、逆走車と反対の車線でかつ逆走車より先行する車両と通信できる位置に設置された第二の路上機に対し、周囲の車両に逆走情報の送信を要請する指示を送信し、これを受けた第二の路上機が逆走車の反対車線にいる車両に対し、逆走情報の送信を要請し、この送信要請を受けた車両が、逆走車と同じ車線で、衝突の危険性のある車両に対し、逆走情報を送信するものである。 Embodiment 1 FIG.
In the first embodiment, the first road machine that detects a reverse running vehicle is in a lane opposite to the reverse running vehicle and is installed at a position where it can communicate with a vehicle preceding the reverse running car. Sends an instruction to the surrounding vehicle to request reverse transmission information, and the second road machine that has received this request requests the vehicle in the opposite lane of the reverse vehicle to transmit reverse travel information. A vehicle that has received a transmission request transmits reverse running information to a vehicle that is in the same lane as a reverse running vehicle and has a risk of collision.

図１は、この発明の実施の形態１による逆走情報通知システムの構成を示すブロック図である。
図１において、路上機１００（第一の路上機）は、逆走車を検知する逆走検知手段１０１と、どの路上機に対して逆走情報送信要請を指示するかを決定する逆走情報送信要請判定手段１１０（路上機選定手段）と、決定した路上機３００に対して、逆走情報送信要請実施指示を送信する逆走情報送信要請実施指示送信手段１１１とを有している。
路上機３００（第二の路上機）は、路上機１００からの逆走情報送信要請実施指示を受信する逆走情報送信要請実施指示受信手段３０１と、逆走車の反対車線（対向車線）にいる周囲の車両に対して、逆走情報送信要請を送信する逆走情報送信要請送信手段３０２とを有する。 FIG. 1 is a block diagram showing a configuration of a reverse running information notification system according to Embodiment 1 of the present invention.
In FIG. 1, a road machine 100 (first road machine) includes reverse running detection means 101 that detects a reverse running vehicle and reverse running information that determines which road machine is to issue a reverse running information transmission request. The transmission request determination means 110 (road equipment selection means) and the reverse travel information transmission request execution instruction transmission means 111 that transmits a reverse travel information transmission request execution instruction to the determined road equipment 300 are provided.
The road machine 300 (second road machine) includes a reverse running information transmission request execution instruction receiving unit 301 that receives a reverse running information transmission request execution instruction from the road machine 100, and an opposite lane (opposite lane) of the reverse running vehicle. Reverse traveling information transmission request transmission means 302 is provided for transmitting a reverse traveling information transmission request to surrounding vehicles.

車両４００（送信要請を受けた車両）は、逆走情報送信要請を受信する逆走情報送信要請受信手段４０１と、逆走情報を送信する逆走情報送信手段４０２とを有する。
車両５００は、逆走情報を受信する逆走情報受信手段５０１と、運転を支援する運転支援手段５０２とを有する。
なお、逆走情報とは、逆走車の存在を示す情報のことを指し、逆走情報送信要請とは、逆走情報を送信させるための要請を指し、逆走情報送信要請実施指示とは、逆走情報送信要請を実施させる指示を指す。 The vehicle 400 (a vehicle that has received a transmission request) has a reverse running information transmission request receiving unit 401 that receives a reverse running information transmission request, and a reverse running information transmission unit 402 that transmits reverse running information.
The vehicle 500 includes reverse running information receiving means 501 that receives reverse running information and driving support means 502 that supports driving.
Reverse running information refers to information indicating the presence of a reverse running vehicle, reverse running information transmission request refers to a request for transmitting reverse running information, and reverse running information transmission request execution instruction Indicates an instruction to execute a reverse run information transmission request.

路上機３００は、道路の近傍に備えられた通信設備であり、例えば、ＥＴＣ（Ｅｌｅｃｔｒｏｎｉｃ Ｔｏｌｌ Ｃｏｌｌｅｃｔｉｏｎ Ｓｙｓｔｅｍ）ゲートや、ＩＴＳ（Ｉｎｔｅｌｌｉｇｅｎｔ Ｔｒａｎｓｐｏｒｔ Ｓｙｓｔｅｍｓ）スポット（ＤＳＲＣ（Ｄｅｄｉｃａｔｅｄ Ｓｈｏｒｔ Ｒａｎｇｅ Ｃｏｍｍｕｎｉｃａｔｉｏｎｓ）通信機）、光ビーコン通信機、ＧｒｅｅｎＷａｖｅ通信機などが挙げられる。
また、路上機１００は、路上機３００と同様の通信設備でもよいし、例えば、降雪状況を遠隔で目視するために設けられたカメラ設備でもよい。また、路上機１００と路上機３００はそれぞれの特徴を同時に持っていてもよい。 The roadside machine 300 is a communication facility provided in the vicinity of a road. For example, an ETC (Electronic Toll Collection System) gate, an ITS (Intelligent Transport Systems) spot (DSRC (Dedicated Short Range Communication optical beacon) Examples include a communication device and a Green Wave communication device.
In addition, the road machine 100 may be a communication facility similar to the road machine 300, or may be a camera facility provided for remotely viewing a snowfall situation, for example. Moreover, the road machine 100 and the road machine 300 may have each characteristic simultaneously.

路上機１００の逆走検知手段１０１は、例えば、逆走車が自身の逆走を示す情報を送信していれば、これを受信することで検知しても良いし、逆走車が送信する自身の位置情報の推移から走行経路を導出することで検知しても良い。
また、複数の路上機１００があるときに、これらと通信した順番から車両の進行方向を導出することで検知しても良い。
また、特許文献１に記載されたように、高速道路の出口ゲートにおいて、入口ゲートを適切に通過したことを示す情報を有していないときに、出口ゲートから侵入したと判定して検知してもよい。
さらに、通信以外の手段、例えば、道路の様子を撮影したカメラの映像を分析することで検知しても良いし、作業員が目視で発見したものを所定の手続きでシステムに入力しても良い。 For example, if the reverse running vehicle has transmitted information indicating its own reverse running, the reverse running detection means 101 of the road machine 100 may detect it by receiving it, or the reverse running vehicle will transmit. You may detect by deriving a driving route from transition of own position information.
In addition, when there are a plurality of on-road devices 100, detection may be performed by deriving the traveling direction of the vehicle from the order of communication with these.
In addition, as described in Patent Document 1, when the exit gate of the expressway does not have information indicating that the entrance gate has been properly passed, it is determined that the entrance gate has entered and detected. Also good.
Furthermore, it may be detected by analyzing means other than communication, for example, a video of a camera that has photographed the state of the road, or what the worker has found visually can be input to the system by a predetermined procedure. .

路上機１００の逆走情報送信要請判定手段１１０は、多数設置された路上機のうち、どの路上機に対して逆走情報送信要請を指示するかを決定する。
例えば、逆走車の進行方向にあって、かつ逆走車の反対車線の車両と通信できるように設置された路上機から逆走情報送信要請を送信すれば、逆走車より先行する車両に逆走情報を送信させることができる可能性が高い。
逆に、逆走車の進行方向と逆方向にある路上機は、進行方向上にある路上機と比べて、逆走車よりも先行しない車両としか通信できない可能性が高い。逆走車より先行しない車両は、逆走情報を早期に提供できる効果が望みにくい。
この場合、逆走情報送信要請判定手段１１０では、逆走車の進行方向上の路上機に対して、逆走情報送信要請実施指示を送信する。 The reverse travel information transmission request determination means 110 of the road device 100 determines which of the road devices among the many installed road devices to instruct the reverse travel information transmission request.
For example, if you send a reverse travel information transmission request from a road machine installed in a traveling direction of a reverse running vehicle and capable of communicating with a vehicle in the opposite lane of the reverse running vehicle, the vehicle preceding the reverse running vehicle There is a high possibility that reverse running information can be transmitted.
Conversely, a road machine in the direction opposite to the traveling direction of the reverse traveling vehicle is likely to be able to communicate only with a vehicle that does not precede the reverse traveling vehicle, compared to a road machine in the traveling direction. Vehicles that do not precede the reverse running vehicle are unlikely to have the effect of providing reverse running information early.
In this case, the reverse running information transmission request determination means 110 transmits a reverse running information transmission request execution instruction to the roadside machine in the traveling direction of the reverse running vehicle.

路上機１００と路上機３００の間では、インターネットなどの汎用的な通信網を介して通信しても良いし、専用通信網を介して通信しても良い。
路上機３００と車両４００の間、および車両４００と車両５００の間では、無線通信する。 The road device 100 and the road device 300 may communicate via a general-purpose communication network such as the Internet, or may communicate via a dedicated communication network.
Wireless communication is performed between the road machine 300 and the vehicle 400 and between the vehicle 400 and the vehicle 500.

運転支援手段５０２は、例えば、音声や映像でドライバーに注意を促してもよいし、車両を直接制御して回避行動をとっても良い。   For example, the driving support means 502 may alert the driver with voice or video, or may take an avoidance action by directly controlling the vehicle.
