Road traffic safety refers to the methods and measures used to prevent road users from being killed or seriously injured. Typical road users include pedestrians, cyclists, motorists, vehicle passengers, and passengers of on-road public transport.
Risk compensation is a theory which suggests that people typically adjust their behavior in response to perceived levels of risk, becoming more careful where they sense greater risk and less careful if they feel more protected. Although usually small in comparison to the fundamental benefits of safety interventions, it may result in a lower net benefit than expected or even higher risks.
Seat belt legislation requires the fitting of seat belts to motor vehicles and the wearing of seat belts by motor vehicle occupants to be mandatory. Laws requiring the fitting of seat belts to cars have in some cases been followed by laws mandating their use, with the effect that thousands of deaths on the road have been prevented. Different laws apply in different countries to the wearing of seat belts.
The National Traffic and Motor Vehicle Safety Act was enacted in the United States in 1966 to empower the federal government to set and administer new safety standards for motor vehicles and road traffic safety. The Act was the first mandatory federal safety standards for motor vehicles. The Act created the National Highway Safety Bureau. The Act was one of a number of initiatives by the government in response to increasing number of cars and associated fatalities and injuries on the road following a period when the number of people killed on the road had increased 6-fold and the number of vehicles was up 11-fold since 1925. The reduction of the rate of death attributable to motor-vehicle crashes in the United States represents the successful public health response to a great technologic advance of the 20th century—the motorization of the United States.
Road toll is the term used in New Zealand and Australia for the number of deaths caused annually by road accidents.
Fatalities that result from motor vehicle crashes are the second largest cause of accidental deaths in the United States.
Motorcycle safety is the study of the risks and dangers of motorcycling, and the approaches to mitigate that risk, focusing on motorcycle design, road design and traffic rules, rider training, and the cultural attitudes of motorcyclists and other road users.
Bicycle safety is the use of road traffic safety practices to reduce risk associated with cycling. Risk can be defined as the number of incidents occurring for a given amount of cycling. Some of this subject matter is hotly debated: for example, which types of cycling environment or cycling infrastructure is safest for cyclists. The merits of obeying the traffic laws and using bicycle lighting at night are less controversial. Wearing a bicycle helmet may reduce the chance of head injury in the event of a crash.
Killed or seriously injured (KSI) is a standard metric for safety policy, particularly in transportation and road safety.
Smeed's Law is an empirical rule suggested to relate traffic fatalities to traffic congestion as measured by the proxy of motor vehicle registrations and country population. The law proposes that increasing traffic volume leads to an increase in fatalities per capita, but a decrease in fatalities per vehicle.
This is a list of numbers of motorcycle deaths in U.S. by year from 1994 to 2014. United States motorcycle fatalities increased every year for 11 years after reaching a historic low of 2,116 fatalities in 1997, then increased to over 5,000 around 2008 and then plateaued in the 4 to 5 thousands range in the 2010s. In nine years motorcycle deaths more than doubled from the late 1990s to 2008. Despite providing less than 1% of miles driven, they made up 15% of traffic deaths in 2012.
Reported Road Casualties Great Britain (RRCGB), formerly Road Casualties Great Britain (RCGB) and before that Road Accidents Great Britain (RAGB), is the official statistical publication of the UK Department for Transport (DfT) on traffic casualties, fatalities and related road safety data. This publication, first produced in 1951, is the primary source for data on road casualties in Great Britain. It is based primarily on police STATS19 data. Data has been collected since 1926.
Transportation safety in the United States encompasses safety of transportation in the United States, including automobile crashes, airplane crashes, rail crashes, and other mass transit incidents, although the most fatalities are generated by road incidents annually killing 32,479 people in 2011 to over 42,000 people in 2022. The number of deaths per passenger-mile on commercial airlines in the United States between 2000 and 2010 was about 0.2 deaths per 10 billion passenger-miles. For driving, the rate was 150 per 10 billion vehicle-miles: 750 times higher per mile than for flying in a commercial airplane. For a person who drives a million miles in a lifetime this amounts to a 1.5% chance of death.
86 percent of people in the United States use private automobiles as their primary form of transportation to their workplace.
Road traffic collisions generally fall into one of five common types:
A traffic collision, also known as a motor vehicle collision, or car crash, occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other moving or stationary obstruction, such as a tree, pole or building. Traffic collisions often result in injury, disability, death, and property damage as well as financial costs to both society and the individuals involved. Road transport is statistically the most dangerous situation people deal with on a daily basis, but casualty figures from such incidents attract less media attention than other, less frequent types of tragedy. The commonly used term car accident is increasingly falling out of favor with many government departments and organizations, with the Associated Press style guide recommending caution before using the term. Some collisions are intentional vehicle-ramming attacks, staged crashes, vehicular homicide or vehicular suicide.
Worldwide, it was estimated that 1.25 million people were killed and many millions more were injured in motor vehicle collisions in 2013. This makes motor vehicle collisions the leading cause of death among young adults of 15–29 years of age and the ninth most frequent cause of death for all ages worldwide. In the United States, 40,100 people died and 2.8 million were injured in crashes in 2017, and around 2,000 children under 16 years old die every year.
Traffic collisions in India are a major source of deaths, injuries and property damage every year. The National Crime Records Bureau (NCRB) 2021 report states that there were 155,622 fatalities, highest since 2014, out of which 69,240 deaths were due to two-wheelers. A study by Insurance Institute for Highway Safety, U.S. shows that the use of seat belts significantly reduces the risks and injuries from road accidents, and yet there is no enforcement on use of seat belts in cars. A study by IIT Delhi points out that the national highways constitute only 2% of the length of roads in India, but they account for 30.3% of total road accidents and 36% of deaths.
People who are driving as part of their work duties are an important road user category. First, workers themselves are at risk of road traffic injury. Contributing factors include fatigue and long work hours, delivery pressures, distractions from mobile phones and other devices, lack of training to operate the assigned vehicle, vehicle defects, use of prescription and non-prescription medications, medical conditions, and poor journey planning. Death, disability, or injury of a family wage earner due to road traffic injury, in addition to causing emotional pain and suffering, creates economic hardship for the injured worker and family members that may persist well beyond the event itself.
With 139,000 km of public roads, the Netherlands has one of the most dense road networks in the world – much denser than Germany and France, but still not as dense as Belgium. In 2013, 5,191 km were national roads, 7,778 km were provincial roads, and 125,230 km were municipality and other roads. Dutch roads include 3,530 km of motorways and expressways, and with a motorway density of 64 kilometres per 1,000 km2, the country also has one of the densest motorway networks in the world. In Dutch a motorway is called "autosnelweg" or simply "snelweg"; other expressways are just called "autoweg". According to a 2004 estimate, some 12,500 km of road remain as yet unpaved.
