Economist Anthony Downs argues that rush hour traffic congestion is inevitable because of the benefits of having a relatively standard work day . In a capitalist economy, goods can be allocated either by pricing (ability to pay) or by queueing (first-come first-served); congestion is an example of the latter. Instead of

Rights to the Daimler brand name were sold to other manufacturers. In 1890, Émile Levassor and Armand Peugeot of France began producing vehicles with Daimler engines, and so laid the foundation of the automotive industry in France . In 1891, Auguste Doriot and his Peugeot colleague Louis Rigoulot completed

Similarly the costs to society of car use may include; maintaining roads , land use , air pollution , noise pollution , road congestion , public health , health care, and of disposing of the vehicle at the end of its life; and can be balanced against the value of the benefits to society that car use generates. Societal benefits may include: economy benefits, such as job and wealth creation, of car production and maintenance, transportation provision, society wellbeing derived from leisure and travel opportunities, and revenue generation from
2862-405: Is a condition in transport that is characterized by slower speeds, longer trip times, and increased vehicular queueing . Traffic congestion on urban road networks has increased substantially since the 1950s, resulting in many of the roads becoming obsolete. When traffic demand is great enough that the interaction between vehicles slows the traffic stream, this results in congestion. While congestion
2968-564: Is a possibility for any mode of transportation , this article will focus on automobile congestion on public roads. As demand approaches the capacity of a road (or of the intersections along the road), extreme traffic congestion sets in. When vehicles are fully stopped for periods of time, this is known as a traffic jam or (informally) a traffic snarl-up or a tailback . Drivers can become frustrated and engage in road rage . Drivers and driver-focused road planning departments commonly propose to alleviate congestion by adding another lane to

The assembly line forced workers to work at a certain pace with very repetitive motions which led to more output per worker while other countries were using less productive methods. In the automotive industry, its success was dominating, and quickly spread worldwide seeing

Many governments use fiscal policies, such as road tax , to discourage the purchase and use of more polluting cars; and many cities are doing the same with low-emission zones . Fuel taxes may act as an incentive for the production of more efficient, hence less polluting, car designs (e.g., hybrid vehicles ) and

3392-534: Is in full use for more hours per day. It may also encourage travellers to pick alternate modes with a lower environmental impact, such as public transport or bicycles. It has been argued that traffic congestion, by reducing road speeds in cities, could reduce the frequency and severity of road crashes. More recent research suggests that a U-curve exists between the number of accidents and the flow of traffic, implying that more accidents happen not only at high congestion levels, but also when there are very few vehicles on
3498-621: Is that cars can use lighter batteries. Most cars are designed to carry multiple occupants, often with four or five seats. Cars with five seats typically seat two passengers in the front and three in the rear. Full-size cars and large sport utility vehicles can often carry six, seven, or more occupants depending on the arrangement of the seats. On the other hand, sports cars are most often designed with only two seats. Utility vehicles like pickup trucks , combine seating with extra cargo or utility functionality. The differing needs for passenger capacity and their luggage or cargo space has resulted in

Another change is that while early cars' pedals were physically linked to the brake mechanism and throttle, in the early 2020s, cars have increasingly replaced these physical linkages with electronic controls. Cars are typically equipped with interior lighting which can be toggled manually or be set to light up automatically with doors open, an entertainment system which originated from car radios , sideways windows which can be lowered or raised electrically (manually on earlier cars), and one or multiple auxiliary power outlets for supplying portable appliances such as mobile phones , portable fridges, power inverters , and electrical air pumps from

Even so, only major makers could afford high costs, and even companies with decades of production, such as Apperson , Cole , Dorris , Haynes , or Premier, could not manage: of some two hundred American car makers in existence in 1920, only 43 survived in 1930, and with
4876-556: The 1950s. Congested roads can be seen as an example of the tragedy of the commons . Because roads in most places are free at the point of usage, there is little financial incentive for drivers not to over-use them, up to the point where traffic collapses into a jam, when demand becomes limited by opportunity cost . Privatization of highways and road pricing have both been proposed as measures that may reduce congestion through economic incentives and disincentives . Congestion can also happen due to non-recurring highway incidents, such as

The BRIC countries are adding to this consumption. As of 2023 few production cars use wheel hub motors . In almost all hybrid (even mild hybrid ) and pure electric cars regenerative braking recovers and returns to a battery some energy which would otherwise be wasted by friction brakes getting hot. Although all cars must have friction brakes (front disc brakes and either disc or drum rear brakes ) for emergency stops, regenerative braking improves efficiency, particularly in city driving. Cars are equipped with controls used for driving, passenger comfort, and safety, normally operated by

Traffic congestion occurs in time and space, i.e., it is a spatiotemporal process. Therefore, another classification schema of traffic congestion is associated with some common spatiotemporal features of traffic congestion found in measured traffic data. Common spatiotemporal empirical features of traffic congestion are those features, which are qualitatively

For example, when new lanes are created, households with a second car that used to be parked most of the time may begin to use this second car for commuting. Reducing road capacity has in turn been attacked as removing free choice as well as increasing travel costs and times, placing an especially high burden on

In response to the increased demand to public transit caused by these policies, aggressive programs to rapidly expand public transport systems in many Chinese cities are currently underway. A unique Chinese phenomenon of severe traffic congestion occurs during Chunyun Period or Spring Festival travel season. It is a long-held tradition for most Chinese people to reunite with their families during Chinese New Year . People return to their hometown to have
7738-528: The idea of different makes of cars produced by one company, called the General Motors Companion Make Program , so that buyers could "move up" as their fortunes improved. Reflecting the rapid pace of change, makes shared parts with one another so larger production volume resulted in lower costs for each price range. For example, in the 1930s, LaSalles , sold by Cadillac , used cheaper mechanical parts made by Oldsmobile ; in
7844-403: The individual include acquiring the vehicle, interest payments (if the car is financed), repairs and maintenance , fuel, depreciation , driving time, parking fees, taxes, and insurance . The costs to society include maintaining roads, land-use , road congestion , air pollution , noise pollution , public health , and disposing of the vehicle at the end of its life . Traffic collisions are
7950-476: The largest cause of injury-related deaths worldwide. Personal benefits include on-demand transportation, mobility, independence, and convenience. Societal benefits include economic benefits, such as job and wealth creation from the automotive industry , transportation provision, societal well-being from leisure and travel opportunities, and the generation of revenue from taxation. People's ability to move flexibly from place to place has far-reaching implications for
8056-603: The last digit of the plate number during rush hours every weekday, traffic in this 20-million-strong city still experiences severe congestion. According to experts, this is due to the accelerated rate of motorization occurring since 2003 and the limited capacity of public transport . In São Paulo, traffic is growing at a rate of 7.5% per year, with almost 1,000 new cars bought in the city every day. The subway has only 61 kilometres (38 mi) of lines, though 35 further kilometers are under construction or planned by 2010. Every day, many citizens spend between three up to four hours behind
8162-637: The last years of the 19th century, Benz was the largest car company in the world with 572 units produced in 1899 and, because of its size, Benz & Cie., became a joint-stock company . The first motor car in central Europe and one of the first factory-made cars in the world, was produced by Czech company Nesselsdorfer Wagenbau (later renamed to Tatra ) in 1897, the Präsident automobil. Daimler and Maybach founded Daimler Motoren Gesellschaft (DMG) in Cannstatt in 1890, and sold their first car in 1892 under
8268-592: The less developed interior. The process reverses near the end of Chunyun. With almost 3 billion trips made in 40 days of the 2016 Chunyun Period, the Chinese intercity transportation network is extremely strained during this period. The August 2010 China National Highway 110 traffic jam in Hebei province caught media attention for its severity, stretching more than 100 kilometres (62 mi) from August 14 to 26, including at least 11 days of total gridlock . The event
8374-580: The location for the accelerator and brake, but this was not always the case. Controls are evolving in response to new technologies, for example, the electric car and the integration of mobile communications. Some of the original controls are no longer required. For example, all cars once had controls for the choke valve, clutch, ignition timing , and a crank instead of an electric starter . However, new controls have also been added to vehicles, making them more complex. These include air conditioning , navigation systems , and in-car entertainment . Another trend
8480-422: The longest trip by a petrol-driven vehicle when their self-designed and built Daimler powered Peugeot Type 3 completed 2,100 kilometres (1,300 mi) from Valentigney to Paris and Brest and back again. They were attached to the first Paris–Brest–Paris bicycle race, but finished six days after the winning cyclist, Charles Terront . The first design for an American car with a petrol internal combustion engine
8586-710: The low income residents who must commute to work. Increased supply can include: Reduction of demand can include: Use of so-called intelligent transportation systems , which guide traffic: Traffic during peak hours in major Australian cities, such as Sydney, Melbourne, Brisbane and Perth, is usually very congested and can cause considerable delay for motorists. Australians rely mainly on radio and television to obtain current traffic information. GPS, webcams , and online resources are increasingly being used to monitor and relay traffic conditions to motorists. Traffic jams have become intolerable in Dhaka. Some other major reasons are
8692-545: The market. In Japan, car production was very limited before World War II. Only a handful of companies were producing vehicles in limited numbers, and these were small, three-wheeled for commercial uses, like Daihatsu , or were the result of partnering with European companies, like Isuzu building the Wolseley A-9 in 1922. Mitsubishi was also partnered with Fiat and built the Mitsubishi Model A based on
8798-426: The nature of societies . The English word car is believed to originate from Latin carrus / carrum "wheeled vehicle" or (via Old North French ) Middle English carre "two-wheeled cart", both of which in turn derive from Gaulish karros " chariot ". It originally referred to any wheeled horse-drawn vehicle , such as a cart , carriage , or wagon . "Motor car", attested from 1895,
8904-414: The network. These models are then typically calibrated by measuring actual traffic flows on the links in the network, and the baseline flows are adjusted accordingly. A team of MIT mathematicians has developed a model that describes the formation of "phantom jams", in which small disturbances (a driver hitting the brake too hard, or getting too close to another car) in heavy traffic can become amplified into
9010-404: The on-board electrical system. More costly upper-class and luxury cars are equipped with features earlier such as massage seats and collision avoidance systems . Dedicated automotive fuses and circuit breakers prevent damage from electrical overload . Cars are typically fitted with multiple types of lights. These include headlights , which are used to illuminate the way ahead and make
9116-421: The poor correlation of theoretical models to actual observed traffic flows, transportation planners and highway engineers attempt to forecast traffic flow using empirical models. Their working traffic models typically use a combination of macro-, micro- and mesoscopic features, and may add matrix entropy effects, by "platooning" groups of vehicles and by randomizing the flow patterns within individual segments of
9222-446: The road. City planning and urban design practices can have a huge impact on levels of future traffic congestion, though they are of limited relevance for short-term change. Congestion can be reduced by either increasing road capacity (supply), or by reducing traffic (demand). Capacity can be increased in a number of ways, but needs to take account of latent demand otherwise it may be used more strongly than anticipated. Critics of
9328-467: The road. After Jakarta, the worst cities for traffic are Istanbul , Mexico City , Surabaya , and St. Petersburg . Daily congestion in Jakarta is not a recent problem. The expansion of commercial area without road expansion shows worsening daily congestion even in main roads such as Jalan Jenderal Sudirman , Jalan M.H. Thamrin , and Jalan Gajah Mada in the mid-1970s. In 2016, 22 people died as
9434-493: The road. This is ineffective: increasing road capacity induces more demand for driving. Mathematically, traffic is modeled as a flow through a fixed point on the route, analogously to fluid dynamics . Causes of traffic congestion: Traffic congestion occurs when a volume of traffic generates demand for space greater than the available street capacity; this point is commonly termed saturation . Several specific circumstances can cause or aggravate congestion; most of them reduce
9540-619: The same for different highways in different countries measured during years of traffic observations. Common features of traffic congestion are independent on weather , road conditions and road infrastructure, vehicular technology, driver characteristics, day time, etc. Examples of common features of traffic congestion are the features [J] and [S] for, respectively, the wide moving jam and synchronized flow traffic phases found in Kerner's three-phase traffic theory . The common features of traffic congestion can be reconstructed in space and time with
9646-472: The same in France, coming to cars in 1919; between them and other cheap cars in reply such as Renault 's 10CV and Peugeot 's 5CV , they produced 550,000 cars in 1925, and Mors , Hurtu , and others could not compete. Germany's first mass-manufactured car, the Opel 4PS Laubfrosch (Tree Frog), came off the line at Rüsselsheim in 1924, soon making Opel the top car builder in Germany, with 37.5 per cent of
9752-405: The time of the merger of the two companies, Daimler and Maybach were no longer part of DMG. Daimler died in 1900 and later that year, Maybach designed an engine named Daimler-Mercedes that was placed in a specially ordered model built to specifications set by Emil Jellinek . This was a production of a small number of vehicles for Jellinek to race and market in his country. Two years later, in 1902,
9858-436: The total absence of a rapid transit system; the lack of an integrated urban planning scheme for over 30 years; poorly maintained road surfaces, with potholes rapidly eroded further by frequent flooding and poor or non-existent drainage; haphazard stopping and parking; poor driving standards; total lack of alternative routes, with several narrow and (nominally) one-way roads. According to Time magazine, São Paulo has
9964-607: The traditional solution of making the "pipe" large enough to accommodate the total demand for peak-hour vehicle travel (a supply-side solution), either by widening roadways or increasing "flow pressure" via automated highway systems , Downs advocates greater use of road pricing to reduce congestion (a demand-side solution, effectively rationing demand), in turn putting the revenues generated therefrom into public transportation projects. A 2011 study in The American Economic Review indicates that there may be
10070-569: The use of the ASDA and FOTO models. Traffic congestion has a number of negative effects: Road rage is aggressive or angry behavior by a driver of an automobile or other motor vehicle. Such behavior might include rude gestures, verbal insults, deliberately driving in an unsafe or threatening manner, or making threats. Road rage can lead to altercations, assaults, and collisions which result in injuries and even deaths. It can be thought of as an extreme case of aggressive driving . The term originated in
10176-530: The visibility of the car. Interior lights on the ceiling of the car are usually fitted for the driver and passengers. Some vehicles also have a boot light and, more rarely, an engine compartment light. During the late 20th and early 21st century, cars increased in weight due to batteries, modern steel safety cages, anti-lock brakes, airbags, and "more-powerful—if more efficient—engines" and, as of 2019 , typically weigh between 1 and 3 tonnes (1.1 and 3.3 short tons; 0.98 and 2.95 long tons). Heavier cars are safer for
10282-470: The wheel. In order to mitigate the aggravating congestion problem, since June 30, 2008, the road space rationing program was expanded to include and restrict trucks and light commercial vehicles. According to the Toronto Board of Trade, in 2010, Toronto is ranked as the most congested city of 19 surveyed cities, with an average commute time of 80 minutes. The Chinese city of Beijing started
10388-482: The world's attention. Key developments included electric ignition and the electric self-starter (both by Charles Kettering , for the Cadillac Motor Company in 1910–1911), independent suspension , and four-wheel brakes. Since the 1920s, nearly all cars have been mass-produced to meet market needs, so marketing plans often have heavily influenced car design. It was Alfred P. Sloan who established
10494-645: The world's first vehicle to be powered by such an engine. The Niépces' Pyréolophore was fuelled by a mixture of Lycopodium powder (dried spores of the Lycopodium plant), finely crushed coal dust and resin that were mixed with oil, whereas de Rivaz used a mixture of hydrogen and oxygen . Neither design was successful, as was the case with others, such as Samuel Brown , Samuel Morey , and Etienne Lenoir , who each built vehicles (usually adapted carriages or carts) powered by internal combustion engines. In November 1881, French inventor Gustave Trouvé demonstrated
10600-529: The world's worst daily traffic jams. Based on reports from the Companhia de Engenharia de Tráfego , the city's traffic management agency, the historical congestion record was set on May 23, 2014, with 344 kilometres (214 mi) of cumulative queues around the city during the evening rush hour. The previous record occurred on November 14, 2013, with 309 kilometres (192 mi) of cumulative queues. Despite implementation since 1997 of road space rationing by
10706-442: The worst traffic congestion in the world, wasting 74 hours in traffic in 2014. Some traffic engineers have attempted to apply the rules of fluid dynamics to traffic flow, likening it to the flow of a fluid in a pipe. Congestion simulations and real-time observations have shown that in heavy but free flowing traffic, jams can arise spontaneously, triggered by minor events (" butterfly effects "), such as an abrupt steering maneuver by
10812-645: Was caused by a combination of road works and thousands of coal trucks from Inner Mongolia 's coalfields that travel daily to Beijing. The New York Times has called this event the "Great Chinese Gridlock of 2010." The congestion is regarded as the worst in history by duration, and is one of the longest in length after the 175 kilometres (109 mi) long Lyon-Paris traffic jam in France on February 16, 1980. Recently, in Hangzhou City Brain has become active, reducing traffic congestion somewhat. A 2021 study of subway constructions in China found that in
10918-407: Was developed in 1926. This is the source of Ford's apocryphal remark, "any color as long as it's black". In 1914, an assembly line worker could buy a Model T with four months' pay. Ford's complex safety procedures—especially assigning each worker to a specific location instead of allowing them to roam about—dramatically reduced the rate of injury. The combination of high wages and high efficiency
11024-1429: Was formed from a conglomerate of six companies who banded together as Fuji Heavy Industries , as a result of having been broken up under keiretsu legislation. The transport sector is a major contributor to air pollution , noise pollution and climate change . Most cars in use in the early 2020s run on petrol burnt in an internal combustion engine (ICE). The International Organization of Motor Vehicle Manufacturers says that, in countries that mandate low sulphur motor spirit, petrol-fuelled cars built to late 2010s standards (such as Euro-6) emit very little local air pollution. Some cities ban older petrol-driven cars and some countries plan to ban sales in future. However, some environmental groups say this phase-out of fossil fuel vehicles must be brought forwards to limit climate change. Production of petrol-fuelled cars peaked in 2017. Other hydrocarbon fossil fuels also burnt by deflagration (rather than detonation ) in ICE cars include diesel , autogas , and CNG . Removal of fossil fuel subsidies , concerns about oil dependence , tightening environmental laws and restrictions on greenhouse gas emissions are propelling work on alternative power systems for cars. This includes hybrid vehicles , plug-in electric vehicles and hydrogen vehicles . Out of all cars sold in 2021, nine per cent were electric, and by
11130-414: Was granted a patent for a "New Rational Combustion Engine". In 1897, he built the first diesel engine . Steam-, electric-, and petrol-driven vehicles competed for a few decades, with petrol internal combustion engines achieving dominance in the 1910s. Although various pistonless rotary engine designs have attempted to compete with the conventional piston and crankshaft design, only Mazda 's version of
11236-427: Was made in 1877 by George Selden of Rochester, New York . Selden applied for a patent for a car in 1879, but the patent application expired because the vehicle was never built. After a delay of 16 years and a series of attachments to his application, on 5 November 1895, Selden was granted a US patent ( U.S. patent 549,160 ) for a two-stroke car engine, which hindered, more than encouraged , development of cars in
