⭐ Core Definition: Traffic congestion

Traffic congestion is a condition in transport that is characterized by slower speeds, longer trip times, and increased vehicular queuing. 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 is a possibility for any mode of transportation, this article will focus on automobile congestion on public roads. Mathematically, traffic is modeled as a flow through a fixed point on the route, analogously to fluid dynamics.

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, a traffic snarl-up (informally) 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 road; however, this is ineffective as increasing road capacity induces more demand for driving.

👉 Traffic congestion in the context of Commuting

Commuting is periodically recurring travel between a place of residence and place of work or study, where the traveler, referred to as a commuter, leaves the boundary of their home community. By extension, it can sometimes be any regular or often repeated travel between locations, even when not work-related. The modes of travel, time taken and distance traveled in commuting varies widely across the globe. Most people in least-developed countries continue to walk to work. The cheapest method of commuting after walking is usually by bicycle, so this is common in low-income countries but is also increasingly practised by people in wealthier countries for environmental, health, and often time reasons. In middle-income countries, motorcycle commuting is very common.

The next technology adopted as countries develop is more dependent on location: in more populous, older cities, especially in Eurasia mass transit (rail, bus, etc.) predominates, while in smaller, younger cities, and large parts of North America and Australasia, commuting by personal automobile is more common. A small number of very wealthy people, and those working in remote locations around the world, also commute by air travel, often for a week or more at a time rather than the more typical daily commute. Transportation links that enable commuting also impact the physical layout of cities and regions, allowing a distinction to arise between mostly-residential suburbs and the more economically focused urban core of a city (process known as suburban sprawl), but the specifics of how that distinction is realized remain drastically different between societies, with Eurasian "suburbs" often being more densely populated than North American "urban cores".

Traffic congestion in the context of Thessaloniki metropolitan area

The Thessaloniki metropolitan area or larger urban zone (LUZ) is the complete area covered and directly influenced by Thessaloniki. The metropolitan area traditionally consisted of the municipality of Thessaloniki and its immediate surroundings, which is today referred to as the Thessaloniki urban area. However, since the mid to late 1990s, the areas surrounding the urban area have succumbed to urban sprawl and what used to be agrarian communities are rapidly urbanizing and being developed into suburbs or exurbs. This is creating new problems for a region already facing issues such as pollution, traffic congestion and social ills.

Thessalonians usually refer to 6 municipalities and 1 municipal unit as the "City of Thessaloniki" (or the Thessaloniki urban area); this is the contiguous densely built-up urban area of the city. However, the metropolitan area also includes the city's immediate surroundings, adjacent zone of influence and its low to medium density suburbs that surround the densely built-up urban area.

Traffic congestion in the context of Rush hour

A rush hour (American English, British English) or peak hour (Australian English, Indian English) is a part of the day during which traffic congestion on roads and crowding on public transport is at its highest. Normally, this happens twice every weekday: once in the morning and once in the afternoon or evening, the times during which most people commute. The term is often used for a period of peak congestion that may last for more than one hour.

The term is very broad, but often refers specifically to private automobile transportation traffic, even when there is a large volume of cars on a road but not many people, or if the volume is normal but there is some disruption of speed. By analogy to vehicular traffic, the term Internet rush hour has been used to describe periods of peak data network usage, resulting in delays and slower delivery of data packets.

Traffic congestion in the context of Quezon City

Quezon City (UK: /ˈkzɒn/, US: /ˈksɒn/; Filipino: Lungsod Quezon [luŋˈsod ˈkɛson] ), also known as the City of Quezon and Q.C. (read and pronounced in Filipino as Kyusi), is the most populous city in the Philippines. According to the 2024 census, it has a population of 3,084,270 people. It was founded on October 12, 1939, and was named after Manuel L. Quezon, the second president of the Philippines. Quezon City served as the capital of the Philippines from 1948 until 1976, when the designation was returned to Manila.

The city was intended to be the national capital of the Philippines that would replace Manila, as the latter was suffering from overcrowding, lack of housing, poor sanitation, and traffic congestion. To create Quezon City, several barrios were carved out from the towns of Caloocan, Marikina, San Juan and Pasig, in addition to the eight vast estates the Philippine government purchased for this purpose. It was officially proclaimed the national capital on October 12, 1949, and several government departments and institutions moved out of Manila and settled into the new capital city. This necessitated the expansion of the city northward, carving out Novaliches from Caloocan which divided it into two non-contiguous parts. Several barrios were also taken from San Mateo and parts of Montalban. However, on June 24, 1976, Presidential Decree No. 940 was enacted, which reverted national capital status to Manila while the whole of Metro Manila was designated as the seat of government. The city was also chosen as the regional center of Southern Tagalog, which was created in 1965, along with the provinces of Quezon and Aurora, the birthplace of Manuel L. Quezon; however, its status of regional center became ineffective when the region was divided into Calabarzon and Mimaropa, through the effect of Executive Order No. 103 in May 2002 under the presidency of Gloria Macapagal Arroyo, and Aurora was transferred to the authority of Central Luzon, with Southern Tagalog limited to being a cultural-geographic region.

Traffic congestion in the context of Bike courier

Bicycle messengers (also known as bike or cycle couriers) are people who work for courier companies (also known as messenger companies) carrying and delivering items by bicycle. Bicycle messengers are most often found in the central business districts of metropolitan areas. Courier companies use bike messengers because bicycle travel is less subject to unexpected holdups in city traffic jams, and is not deterred by parking limitations, fees or fines in high-density development that can hinder or prevent delivery by motor vehicle, thereby offering a predictable delivery time.

Because bicycle thefts are prevalent in many cities, a lock to secure the bike during deliveries is essential. U-locks are also popular. Messengers typically carry basic tools, weather-proof clothing and a street map. It is also common for messengers to carry storage clipboards for manifests, receipts, and/or other logistic documents.

Traffic congestion in the context of Congestion pricing in New York City

Congestion pricing in New York City, also known as the Central Business District Tolling Program or CBDTP, began on January 5, 2025. It applies to most motor vehicular traffic using the central business district area of Manhattan south of 61st Street, known as the Congestion Relief Zone, in an effort to encourage commuters to use public transportation instead. This Pigovian tax, intended to cut down on traffic congestion and pollution, was first proposed in 2007 and included in the 2019 New York State government budget by the New York State Legislature. Tolls are collected electronically and vary depending on the time of day, type of vehicle, and whether a vehicle has an E-ZPass toll transponder. The Metropolitan Transportation Authority (MTA) estimates $15 billion in available capital will be generated by bonding revenues from the tolls, which will be available to fund repairs and improvements to the subway, bus, and commuter rail systems.

As of 2024, New York City led the world in urban automobile traffic congestion, despite having a 24/7 rapid transit system. Since the early 20th century, several proposals have been floated for traffic congestion fees or limits for vehicles traveling into or within the Manhattan central business district. A recurring proposal was adding tolls to all crossings of the East River, which separates the borough of Manhattan from the boroughs of Brooklyn and Queens.

Traffic congestion in the context of Induced demand

In economics, induced demand – related to latent demand and generated demand – is the phenomenon whereby an increase in supply results in a decline in price and an increase in consumption. In other words, as a good or service becomes more readily available and mass produced, its price goes down and consumers are more likely to buy it, meaning that the quantity demanded subsequently increases. This is consistent with the economic model of supply and demand.

In transportation planning, induced demand, also called "induced traffic" or consumption of road capacity, has become important in the debate over the expansion of transportation systems, and is often used as an argument against increasing roadway traffic capacity as a cure for congestion. Induced traffic may be a contributing factor to urban sprawl. City planner Jeff Speck has called induced demand "the great intellectual black hole in city planning, the one professional certainty that every thoughtful person seems to acknowledge, yet almost no one is willing to act upon."

Traffic congestion in the context of Chesapeake Bay Bridge

The Gov. William Preston Lane Jr. Memorial Bridge (informally called the Chesapeake Bay Bridge and, locally, the Bay Bridge) is a major dual-span bridge in the U.S. state of Maryland. Spanning the Chesapeake Bay, it connects the state's rural Eastern Shore region with its urban and suburban Western Shore, running between Stevensville and Sandy Point State Park near the capital city of Annapolis. The original span, opened in 1952 and with a length of 4 miles (6.4 km), was the world's longest continuous over-water steel structure. The parallel span was added in 1973. The bridge is named for William Preston Lane Jr., who, as the 52nd Governor of Maryland, launched its construction in the late 1940s after decades of political indecision and public controversy.

The bridge is part of U.S. Route 50 (US 50) and US 301, and serves as a vital link in both routes. As part of cross-country US 50, it connects the Baltimore–Washington Metropolitan Area with Ocean City, Maryland, Rehoboth Beach, Delaware, and other coastal tourist destinations. As part of US 301, it serves as part of an alternative route for Interstate 95 travelers, between northern Delaware and the Washington, D.C., area. The bridge is busy and often congested with traffic, particularly during peak hours and summer months.
