So in a broad sense,Road traffic accident,Railway traffic accident,Maritime traffic accident,Air traffic accidentIncluding all of. The existing encyclopedia "Japan Encyclopedia" also discusses land, sea, and air traffic.[1].

In addition to road traffic accidents, it may also be used in a broad sense, including road traffic accidents, railway traffic accidents, marine traffic accidents, and air traffic accidents, in traffic safety measures and statistics.[2].. Although,道路InAutomobile-Bicycle-PedestrianOccurred duringRoad traffic accident(As automobiles, motorcycles, and bicycles are most commonly used and most frequently used in society as a whole, the number of accidents is higher than that of ships and aircraft.)

In this encyclopedia,There is no other article in this article that gives an overview of traffic accidents in a broad sense, that is, with a view of all aspects of railways, seas, aviation, and roads, so at the beginning of this article OverviewThen,In the section below, we also describe the details of the most familiar traffic accidents, road traffic accidents...

Overview of traffic accidents in a broad sense

Traffic accidents are classified into "road accidents (car accidents)" and "railway traffic accidents (Railway accident)" "Marine accident (marine accident)""Air traffic accident (air traffic accident)Is roughly divided into[1].

1970 eraSince then, the means of transportation have become larger, more multifunctional, and faster, so once an accident occurs, it could lead to the death of many people and the loss of many goods. Became higher[1].. Traffic accidents are one of the modern social unrest[1].

Aging of simple statistics

For example, comparing the casualty statistics from wide-ranging traffic accidents in Japan by type, the results are as follows.[1].

  • Road traffic accident(死傷者):65万3582人(1984)、105万9403人(1999)、91万5029人(2009)、58万4544人(2017)[1].
  • Railway track traffic accident(Injured and injured): 1538 (1984), 689 (1999), 683 (2009), 561 (2017)[1].
  • Maritime traffic accident(Dead and missing): 252 (1984), 146 (1999), 142 (2009), 54 (2017)[1].
  • Air traffic accident(Civil aircraft only): 46 (1984), 26 (1999), 9 (2009), 28 (2017)[1].

Types of road traffic accidents

Traffic accidents include personal injury and property damage[3].. In addition, there are the following types of accidents (reference “Actual conditions of traffic accidents in automobile insurance data”)[3].

  • People vs vehicles
  • Vehicle-to-vehicle (vehicle-to-vehicle accident)
    • Head-on collision
    • Side impact
    • Meeting collision
    • Contact accident
    • Rear-end collision
    • Reverse collision
  • Vehicle alone accident
    • Off-road deviation
    • Structure collision
    • Vehicle rollover
    • Vehicle fall

In addition to this, there have also been "vehicle-to-animal" collisions (see detailsRoadkill # RoadkillSee).Japan Automobile Federation(JAF) is careful not to collide with animals, when it discovers a carcass of an animal that may interfere with the passage of vehicles following it, report to the police in case of collision and rescue / removal of the animal (if possible) ofRoad emergency dialTo report to[4].

Causes of road traffic accidents

      • On the roadAnimalPopping out-fences to prevent invasion, animal tunnels (dedicated underground tunnels for animals), animal pathways (a dedicated bridge built in the air for animals) and other workarounds are often taken.

Deterring dangerous acts by law

In many countries, acts that cause traffic accidents are prohibited or regulated by law, and caution is required.

Japanese traffic accidents

Definition of traffic accident

The laws and regulations that define the definition of traffic accidents include:

  1. Road Traffic Law: Vehicles on the road (Automobile,Motorized bicycle,BicycleSuch asnon-motorized vehicle,trolley bus,Tram) Traffic damage or damage to persons (Article 67, Paragraph 2 of the Road Traffic Act)
  2. Car Safe Driving Center Act: Including those that occur outside the road in the items specified in Article 67, Paragraph 2 of the Road Traffic Act
  3. Automotive Damages Protection Act: A person who provides a car for his/her own operation shall be liable for the damage caused by the damage of the life or body of others due to the operation. (Article 3 of the Compensation Law)
  4. Ministry of Health, Labor and WelfareDisease, injury and death cause classification: Basic classification code V01-V99

and so on. Generally speaking, “traffic accident” refers to a traffic accident under the Road Traffic Law.

Scope of traffic accident and liability for damages

The road traffic law does not include traffic accidents as follows.

  • Accidents outside the "road" under the Road Traffic Act
    • "Road" in the Road Traffic Act isRoad lawStipulate in道路,Road transport lawStipulate inThe motorwayAnd all places used for general traffic. Therefore, it will not be issued for accidents outside the “road” under the Road Traffic Act.
    • However, the term "road" under the Road Traffic Law here does not mean that it is not covered by simply saying that it is a private land or a parking lot.Road # Japanese legal definitionSee). Except for land that is almost purely occupied by people (houses, condominiums, companies, etc.) and roads that are restricted to the public such as factory roads, it is possible to roughly correspond to "roads" under the Road Traffic Act. It is necessary to note that there is a possibility. It is also a point that there are disputes in myths and precedents, so caution is required in the case of an actual accident.
  • In addition, the fact that the presence or absence of issuance of a traffic accident certificate and the presence or absence of a duty to notify the police of a traffic accident (Article 72 of the Road Traffic Act) have not been verified (due to judicial precedents or myths).[Annotation 1]Therefore, this also requires caution in the case of an actual accident.
  • In addition, whether or not a traffic accident certificate is issued and whether or not there is a liability for damages to the victim is irrelevant, and the presence or absence of a liability for damages is not affected by the presence or absence of a certificate (see below).
  • Driver's licenseAs a requirement of the above, a "lethal injury outside the road" was newly established, and it came to have a certain effect on the Road Traffic Law.
  • Accidents not caused by vehicle traffic (driving on the road and parking/stopping)
    • For example, if a car that had its engine turned off spontaneously exploded and burned, or if a person who is boarding a regular place such as a car gets caught in the door or window of the car, For example, when a vehicle parked in a parking lot is damaged by a disaster such as a landslide. In addition, if an accident occurs due to the fact that there is a danger of contact with other people or vehicles on the road by opening or closing the door, a traffic accident will occur ((Door open accident). A traffic accident also occurs if an accident occurs due to an external factor such as an explosion, a flame, or a landslide while driving a vehicle.
    • Incidentally,Automobile liability insuranceAnd the payment standard for arbitrary car insurance is unrelated to the above (described later)
  • PedestrianSingle accident or collision between pedestrians

Whether it corresponds to a road accident under the Road Traffic Law and the legal liability for damages (Automotive Damages Protection ActArticle 3,Civil law709) and moreAutomobile liability insuranceAnd the payment criteria for voluntary car insurance are largely unrelated.

  • Automotive Damages Protection ActArticle 3 "A person who provides a car for his/her own use shall be responsible for compensating for the damage caused by this when the life or body of another person is harmed by the operation." The following precedents are related to the provisions of.
    • Lumber Works When unloading a log of raw wood loaded on an ordinary freight car parked on a road in a private property site from the freight car, the fork of the forklift pushes it from the cargo bed of the freight car to the ground on the opposite side to unload it. However, the accident in which the children who were present together died due to the underlayment of the log was caused by "using the freight car according to the usage of the device." (Positive, June 63, 6 Supreme Court First Small Court Judgment, Showa 16 (e) 59)
    • When a large truck loaded with lumber is parked on the road and the timber of the truck is being unloaded using another forklift, the forklift should be placed in an open space outside the road to adjust the height of the fork. Although the fork part was stopped, the fork part was protruding on the road, and the fork part collided with another car that had been traveling on the road from the time of the accident, and the driver of the car was injured. It is not caused by "use according to the usage of the device", but there is still a liability for damages under Article 709 of the Civil Code. (Positive for compensation, Supreme Court First Small Court Judgment, June 63, 6, Showa 16(e)61)
  • For accidents where a traffic accident certificate is not issued, basicallyNot covered by liability insurance. However, in the car insurance,NormallyCompensation target (Limited to compensation for damages. In some cases, exemption, that is, not covered by compensation. Intentional or earthquake-induced)

Perpetrator's responsibility

Initial support

Article 72 of the Road Traffic Act imposes the following obligations on drivers of vehicles, etc. related to traffic accidents.

  1. Obligation to stop driving immediately (do not leave the site immediately after an accident, etc.)
  2. Obligation to rescue the injured (moving the injured to a safe place and receiving medical treatment as soon as possible)
  3. Obligation to prevent road hazards (duty to prevent secondary accidents)
  4. Obligation to report to police officers the date and time of occurrence, the status of casualties and damage to property, post-accident measures, and loads.
  5. Obligation to obey an order to stay on-site until the police officer arrives if he/she deems it necessary (usually by all means)

In addition, in order to fulfill its civil responsibilities, it is necessary to:

  1. Identification of the other person
  2. Contacting a voluntary insurance company (responsibility for insurance contracts)

It is generally said that about 60% of drivers do not know the initial response to a traffic accident.[6]

Criminal liability

Irrespective of the definition of a traffic accident, if a driver of a vehicle injures or injures a person, the following crimes may be prosecuted depending on the behavior.

In administrative punishment for personal injury, if the perpetrator's negligence is found,Violation of safe driving obligation(2 points) and additional points for traffic accidents related to injury and death (minimum 2 points, maximum 20 points), totaling at least 4 additional points.

The driver will not be subject to administrative sanction in the case of property damage accidents, except personal accidents and building damage accidents.

Impact of traffic accident

Physical impact

When the impact of a traffic accident on the mind and body is the lightest, it is intact (not only is there no injury or bone fracture,WhiplashThere is also no aftereffects such as), but in the worst case, the collision with a running vehicle has a large impact, and if it is hit, there is a case where the whole body or the head is struck and instant death occurs. If you are hit by a vehicle without being hit, the body may be cut or squeezed by being caught in a wheel or trampled, causing rupture of the internal organs, orbrain,内 臓,Blood vesselThere is a situation where the prototype does not stay, such as popping out or being scattered at the scene of an accident resulting in injury or death, and it may lead to death in a tragic state.

The problem of mental sequelae other than the injuries such as the anxiety of the injured suffering mentally immediately after the accident has increased, and the qualification system for emergency medical emergency doctors, doctor helicopters, etc. have recently been enhanced, but the frequent occurrence of traffic accidents is a problem. In Aichi Prefecture (also described in the table below), Kasugai City conducted the first nationwide test as a "doctor car" model, promoting communication with the standby doctor at the main hospital while flying the vital signs of the injured by radio waves. A national qualification for emergency paramedics centered on firefighters who can use defibrillators (ambulators) in the field has been established. The car was jointly developed with Toyota Corporation. Can be done without medical qualificationAEDContributed to the development of the installation. While consideration is being given not only to the body of the injured but also to the mind and spirit, there are many human, equipment, and budget barriers. General recognition required an awareness and cooperation system with the media such as NHK and other media.

Effects on the body

Listed in order of severity,Cervical cord injury, Chest injury, airway obstruction (face injury, neck injury, etc.), abdominal cavitypelvisSuch as damage. Compared to these, deaths from limbs are less likely to occur.

In particular, cervical spinal cord injury, even if it survivesQuality of lifeIs significantly reduced. Immediately after the injury, even if there is no damage, it is likely to occur even if the victim inadvertently moves the neck. It is necessary to thoroughly ensure that if you encounter a traffic accident, do not move your head, neck, or shoulder carelessly. (JPTEC-JATEC(See also section)

Accidents under similar conditions will differ greatly depending on the condition of the collision, the victim's belongings, condition, physical and mental condition at that time, and the weather. When a pedestrian or a person who rides a bicycle collides with a very low-speed car or motorcycle, or when the pedestrian has a large bag and hits the bag, there is no human injury or it is close to it. In some cases.

Compared to accidents due to other factors such as occupational accidents and natural disasters, it is more likely that the victim will be severely impacted on the head and waist,Persistent consciousness disorderBeginning withSequential disabilityThere are quite a few examples in which there remains. Also, if you have a strong impact on your brain,Higher brain dysfunctionMay lead to(Head injury,Traumatic brain injurySee also).


Pedestrian TheBicycleA collision with or even a collision between pedestrians may cause a fatal accident by hitting the head on the road surface.

In recent years, automobile manufacturers have taken the following measures in consideration of safety for pedestrians.

  • bumperPosition of the adult from the position of the thigh/pelvis of the adult to the position of the lower leg.
  • Even if the upper body collides with the front of the passenger car using the above-mentioned part as a fulcrum, the head should hit the hood instead of the windshield.(By making the bonnet member a shock absorbing type, fatal injury to the chest and head may occur. Make it harder)

Number of deaths

The statistics of fatalities in accidents are mainly used when the victims of an accident that were collected by the police died within 24 hours after the accident occurred, and the number of people below is also basically the number of deaths within 24 hours. is there. Other police statistics include deaths within 30 days. Furthermore,Ministry of Health, Labor and Welfare OfDemographic statisticsからlandIt is clear from the number of deaths within one year after the accident caused by the traffic accident in道路The number excluding those who are not judged to be the above-mentioned traffic accident is included as "dead in the welfare statistics"[21].

2020 The number of fatalities in traffic accidents within 24 hours is 2,839[22]As of the end of September 2021, the number of automobiles owned in Japan was about 1 million.[23]By comparison, the number of cars owned was about 38 shortly after the war.[24]1950 Less than 4,202 people, showing how the death toll has dropped dramatically. this is,1949 Less than 24 deaths within 3,790 hours of1948 It is the smallest number since the start of statistics. Also,Emergency medical careThere is a misconception that the number of deaths has not decreased so much just by surviving for more than 24 hours due to the development of2020 The death toll within 30 days is 3,416[25], The death toll within one year of 2019 is 1[26]And both have decreased as well as the death toll within 24 hours. Within 30 days the number of deaths began to collect statistics1993 Since then, the number of deaths within one year has started to be collected.1965 It has been the smallest number since then[27].

Looking at age, the percentage of elderly people aged 2020 and over in 65 in the number of fatalities in traffic accidents was about 56.2%, the highest percentage ever.This is due to the increase in the elderly population and the higher case fatality rate of the elderly than in other age groups.[28].. In addition, according to a survey by the Traffic Accident Analysis Center in June 2016, the number of pedestrian casualties (including cases where pedestrians did not violate) was significantly higher at 6 years old.[29], 2.5 times that of an adult[29], About twice that of the elderly[29]Is. The cause is that there are more opportunities to act away from parents such as going to and from school, without having acquired sufficient traffic rules and the ability to detect danger.[29].

The number of deaths within one year per 2019 people due to traffic accidents in 10 was 1, which is compared to other causes of death.fire0.8 people,murderMore than 0.2 people,EarthquakeOf 14.9 (Great East Japan EarthquakeThe number of 2011 that there was[30]),suicideLess than 15.7[31][27].


Due to the increase in the number of cars owned in Japan, the number of traffic accidents will increase proportionately,2004 Recorded 95 cases.Since then, the number of automobiles owned in Japan has stabilized at about 2709 million, and in 8000 the number of automobiles owned was the highest at about 2020 million, but the number of accidents decreased to 8,231.0 for the 30th consecutive year. doing.This was less than half the current number of cars owned, about 9,178 million.1979 This is the smallest number after 47 cases.[32]

Number of injured



Post-warHigh economic growthThe number of traffic accidents increased during the period1959 Has reached a situation where the number of traffic fatalities per year exceeds 1. Because it is not a war but a huge number of people are sacrificedTraffic war(First traffic war)" became a metaphor. Especially1970 The number of vehicles owned was about 1652 million, and 1 people were killed annually (about 6765 people died within a year) due to a traffic accident, making this the number one year in history. The number of traffic accidents,1969 Was the largest number up to the end of the First Traffic War with 72 cases.

The number of traffic accidents,1977 Has been the smallest since the beginning of the First Traffic War, at 46.
  • 1980 era ~ 1990 era The beginning of the second traffic war The number of accidents and fatalities increased due to the end of the decline in the accident rate and the increase in the number of automobiles owned.
1980 eraSince the safety measures started from the First Traffic War have become widespread, the rate of traffic accidents, which had been decreasing, has stopped declining. Casualty rate, which is an index of traffic accident rate, which takes into account the number of vehicles owned and the distance traveled[Annotation 3]It is,1970 Was over 300 (cases/XNUMX million km),1980 Has dropped to around 120 (cases/XNUMX million km). But then2010 About 30 years until then, the accident rate leveled off in the range of about 120 to 100 (cases/XNUMX million km).[33].
for that reason,1970 eraEven though the accident rate did not decrease from the second half,Bubble economyAs the number of cars owned increased, the number of traffic accidents began to increase again, and the number of fatalities increased accordingly.1988 Once again, the number of people exceeded 1, and the situation became known as the "second traffic war."1992 Has reached 1, the highest number since the end of the First Traffic War. The number of accidents was 1452 in the same year.
  • 1990 era ~ 2000 era End of the Second Traffic War End of the Second Traffic War due to a decrease in the number of fatalities in traffic accidents, increase in the number of traffic accidents
With the increase in the number of cars owned in the Second Traffic War, the majority of traffic accident victims were car occupants, and in the 1990s the number of deaths during riding increased to 1.7 times the number of pedestrian deaths, In the 1990sCar assessmentIs started,Airbag,Shock absorptionbody,Pretensioner(Tightening at the time of collision) With functionSeat beltEfforts are being made to improve safety equipment on the vehicle side, such as2008 Has fallen below the number of pedestrian deaths.

Death toll1996 The number of people was reduced to 1 again, and in 2004 the number dropped to 7425, and the situation called the Second Traffic War ended. On the other hand, although the mortality rate around the accident decreased, the accident rate itself did not decrease, so the number of accidents increased conversely, reaching a record high of 95 in the same year.
  • 2010 era ~ Decrease in the number of traffic accidents and decrease in traffic accident deaths due to the decrease in traffic accident rate itself
2012 For about 30 years, the casualty rate, which had been flat in the range of about 160 to 120 (cases/120 million km), fell below 2016 (cases/85.3 million km), and the traffic accident incidence rate began to decline. In XNUMX, it decreased to about XNUMX (cases/XNUMX million km)[34].. As a result, the number of traffic accidents and the number of traffic fatalities continue to decrease.
The reason why the traffic accident incidence rate, which has been flat for about 30 years, has begun to decrease is to reduce the damage caused by accidents such as airbags during the Second Traffic War.Passive safetyBecame popular as a safety measure, but in the 2010s the accident itself was prevented.Active safetyThe fact that has begun to spread is mentioned. From around 2010Anti-skid device,Collision damage reduction brakeなどが普及しだしており、2014年には自動車アセスメントに予防安全性能アセスメントが追加されている。2016年には年間交通事故による死亡者数が1949年の67年ぶりに3000人レベルにまで減少して、飲酒運転の取り締まりと交通安全文化の普及で交通事故死亡者が最も多かった時期に比べると4分の1の水準に減少した。さらに全交通事故の発生件数も2015年より7.1%減の49万9232件だった[35].. In FY2017, the liability insurance premium was reduced because the accident rate fell due to the spread of technologies that reduce accidents such as automatic braking (collision damage reduction brakes).[36].. August 2019Higashiikebukuro car runaway accidentThe movement to return licenses for the elderly accelerated[37][38].2021 May 4Started collecting daily traffic accident statistics1968 The number of fatalities in traffic accidents for the first time since then has become zero.Furthermore, there were no fatal accidents on that day, and there were no deaths due to injuries due to the traffic accident the day before.[39][40].

交 差点

交 差点(Kosaten,intersectionTomo, crossroads, intersection) means two or more道路Is the place where


An intersection is a part where two or more roads intersect (intersection). Roads intersect with many roads of different levels, and the methods of intersection are roughly divided into level intersections and grade separations. At-grade intersections are intersections with signals and no signals, and grade separations are intersections. There are grade separations and interchanges[1].

There is a lot of traffic across the road,Traffic accidentIs a point where is likely to occur. 2019% of traffic accidents in 54.9 occur at and near intersections[2][3]..As traffic becomes more generalized and developedtraffic lights,crosswalk,FootbridgeThe number of intersections equipped with various incidental facilities has increased.

Also, at the intersectioncityIt also affects the establishment of. At the point where the roads connecting long distances intersect, the flow of people and trade goods intersects and encounters occur, so you do not bother to go to a distant destination, but in the vicinitytransaction(Commercial) Will be performed. Eventually, when products from all over the world began to concentrate,LifeIncreasingly attractive as a place forpopulationFlows in,消费MarketEven so, it will become more important.In this wayTrading city,Transportation cityWas formed.

Form of intersection

There are different trends in each country as to what form is adopted.

The most common is simply crossing the roadsLevel crossingIt is a form to make. In the case of level crossing, if you change direction across the oncoming lane (turn right when passing on the left side), the flow tends to be stagnant, so install a dedicated lane or traffic light on a busy road so as not to obstruct the traffic to the other Be made. On the other hand, even if the vehicle does not cross the oncoming lane (turn left when traveling on the left side), a lane may be provided at an intersection with many crossing pedestrians.

As an at-grade intersection, the roads are connected radially to the circular roundabout.RoundaboutIs also used. Especially when the number of legs is large, it is easy to smooth the flow. It is widespread in Europe.

Especially when there is heavy traffic or the design speed is highMulti-level crossingIs used. The traffic capacity is larger and the safety is higher than the level crossing.General roadIn many cases, only roads with particularly heavy traffic are three-dimensionalized, but at-grade intersections are not provided for all intersecting roads.JunctionThere is also an example.

Types of intersections

Level crossing
  • Three-way junction: An intersection where the destination is divided into two directions. Depending on the shapeJunctionAlso called (T-junction) or Y-junction
  • Four-forked road: An intersection where roads extend in all directions. Two straight roads intersect, and many have no significant acute angles.crossroadsと 呼 ば れ る
  • Five-forked road: An intersection where the road extends in all directions
  • Six-forked road: An intersection where the road extends in all directions
  • Seven forks: An intersection where the road extends in all directions

Intersection in Japan

In Japan, about the crossroadsA streetIt is also a synonym for "intersection". To protect the safety of pedestrians, traffic lights completely separate the flow from the car.Scramble crossingIs also installed. Also, if it is deemed necessaryAutomatic traffic accident recorderThere are also intersections that help analyze accidents by installing.

Road law

Road Traffic LawIn Article XNUMX, Paragraph XNUMX, Item XNUMX, the intersection is "crossroads,JunctionWhen two or more roads intersect, the two or more roads (SidewalkOn a road with a distinction between a road and a road, it is defined as "the intersection of the road".

Articles 5 to XNUMX of the Road Traffic Act regulate the traffic methods at intersections. Also, XNUMX from the intersection and its side edgesMetersIn the part withindecreeOrPolice officerIn addition to pausing by order of, or to prevent dangerStopOrParkingshould not be done.


The official name of the intersection where the signal is installed is for each prefecture.Public Safety Commission, The police, and the road administrator will consult and decide.

The intersection name signs attached to traffic lights at intersections are installed by road managers, and the official names are not always displayed in consideration of local intentions.

In some areas such as Hokkaido, there are cases where the intersection name sign indicates the location of the point where the traffic light is located instead of the official name of the intersection.

範 囲

Traffic accidentIt is necessary to determine which part of the road is an intersection when the occurrence of an intersection, and there are four types of methods for determining the range of an intersection for that purpose.[4][5].

  • Lateral line extension method: The lateral line of the road is extended from the contact point, and the area surrounded by the line is used as the intersection.
  • Vertical start method: A perpendicular line is drawn from the point of contact between roads to the opposite lateral line, and the area surrounded by the line is used as the intersection.
  • Start-end connection method: The intersection is the area surrounded by the lines connecting the points of contact between the roads.
