Cycling infrastructure in the context of "Traffic engineering (transportation)"

Amsterdam (Dutch: [ˌɑmstərˈdɑm] ; lit. 'Dam in the Amstel') is the capital and largest city of the Netherlands. It has a population of 933,680 in June 2024 within the city proper, 1,457,018 in the urban area and 2,480,394 in the metropolitan area. Located in the Dutch province of North Holland, Amsterdam is colloquially referred to as the "Venice of the North", for its large number of canals, now a UNESCO World Heritage Site.

Amsterdam was founded at the mouth of the Amstel River, which was dammed to control flooding. Originally a small fishing village in the 12th century, Amsterdam became a major world port during the Dutch Golden Age of the 17th century, when the Netherlands was an economic powerhouse. Amsterdam was the leading centre for finance and trade, as well as a hub of secular art production. In the 19th and 20th centuries, the city expanded and new neighborhoods and suburbs were built. The city has a long tradition of openness, liberalism, and tolerance. Cycling is key to the city's modern character, and there are numerous biking paths and lanes spread throughout.

Cycling is the second-most common mode of transport in the Netherlands, with 36% of Dutch people listing the bicycle as their most frequent way of getting around on a typical day, as opposed to the car (45%) and public transport (11%). Cycling has a modal share of 27% of all trips (urban and rural) nationwide. In cities this is even higher, such as Amsterdam which has 38%, and Zwolle 46%. This high frequency of bicycle travel is enabled by excellent cycling infrastructure such as cycle paths, cycle tracks, protected intersections, ample bicycle parking and by making cycling routes shorter and more direct (and therefore usually quicker) than car routes.

In the countryside, an increasing number of routes link the Netherlands' villages, towns, and cities. Some of these paths are part of the Dutch National Cycle Network, a system of routes for bicycle tourism that reaches every corner of the nation.

Bicycle-friendly policies and practices help some people feel more comfortable about traveling by bicycle with other traffic. The level of bicycle-friendliness of an environment can be influenced by many factors including town planning and cycling infrastructure decisions. A stigma towards people who ride bicycles and fear of cycling is a social construct that needs to be fully understood when promoting a bicycle friendly culture.

Bicycle parking is part of the cycling infrastructure of a populated place allowing for the storage of bicycles when they are not being used. Parking facilities for bicycles include racks, lockers, parking stations, and covered areas. Bicycle parking infrastructure, in addition to cyclists' equipment such bicycle locks, offers a degree of security and may prevent bicycle theft. Ad hoc bicycle parking alongside railings, signs, and other street furniture is a common practice and may be recognized through formal legal arrangements.

Bicycle parking is an important consideration for the cyclability of a locality. Secure bicycle parking is a factor that influences people's decision to cycle. Bicycle parking at mass transit stations facilitates mixed-mode commuting. The role of bicycle parking in urban planning is studied through the discipline of bicycle transportation planning and engineering. Provisions for bicycle parking may be included in municipal policies and regulations.

There is debate over the safety implications of cycling infrastructure (e.g. cycle tracks, protected intersections). Recent studies generally affirm that segregated cycle tracks have a better safety record between intersections than cycling on major roads in traffic. Furthermore, cycling infrastructure tends to lead to more people cycling. A higher modal share of people cycling is correlated with lower incidences of cyclist fatalities, leading to a "safety in numbers" effect though some contributors caution against this hypothesis. On the contrary, older studies tended to come to negative conclusions about mid-block cycle track safety.

However, the implications for road safety of cycle tracks at intersections is disputed. Studies generally show an increase in collisions at junctions, especially where cyclists are travelling in the direction opposite to the flow of traffic (e.g. on two-way cycle tracks). Protected intersection designs generally improve safety records over non-protected junction types.

Cycleway 3 (C3) is a cycle route in London, England. It is part of the Cycleway network coordinated by TfL. It runs from Barking in the east to Lancaster Gate in central London. It is a popular route with both commuter and leisure cyclists, passing a number of major destinations in London along its route. For almost the entire route, cyclists are separated from other traffic in segregated cycle lanes, and cycling infrastructure has been provided at major interchanges. The cycleway, originally called Cycle Superhighway 3, was renamed to Cycleway 3 in January 2023.
