Cycling infrastructure refers to all infrastructure which may be used by cyclists. This includes the same network of roads and streets used by motorists, except those roads from which cyclists have been banned (e.g., many freeways/motorways), plus additional bikeways that are not available to motor vehicles, such as bike paths, bike lanes, cycle tracks and, where permitted, sidewalks, plus amenities like bike racks for parking and specialized traffic signs and signals.
The manner in which the public roads network is designed, built and managed can have a significant effect on the utility and safety of cycling. The cycling network may be able to provide the users with direct, convenient routes minimizing unnecessary delay and effort in reaching their destinations. Settlements with a dense roads network of interconnected streets tend to be viable utility cycling environments.

A bikeway, or segregated cycling facility, is a lane, route, way or path which in some manner is specifically designed and /or designated for bicycle travel. It comes in various forms and names such as (but not limited to): bike lane, bicycle boulevard, bicycle trail, foreshoreway, greenway, cycle track, sharrow. Some bikeways are separated from motor traffic by physical constraints (e.g. barriers, parking or bollards), but others are separated only by painted markings.
The term bikeway is largely used in North America while in the UK segregated or dedicated cycling facility is preferred. Various guides exist to define the different types of bikeway infrastructure, including UK Department for Transport manual The Geometric Design of Pedestrian, Cycle and Equestrian Routes, the Danish Road Authority guide Registration and classification of paths, the Dutch CROW, the American Association of State Highway and Transportation Officials (AASHTO) Guide to Bikeway Facilities, the Federal Highway Administration (FHWA) Manual on Uniform Traffic Control Devices (MUTCD), and the US National Association of City Transportation Officials (NACTO) Urban Bikeway Design Guide.
There has been a lot of studies on the safety of all types of bikeways. Proponents say that segregation of cyclists from fast or frequent motorized traffic is necessary to provide a safe and welcoming cycling environment. Opponents point out the increased risk from various types of infrastructure including shared use paths.
Different countries have different ways to legally define and enforce bikeways.
Controversies have surrounded bikeways, particularly in North America and the United Kingdom. Some detractors argue that one must be careful in interpreting the operation of dedicated or segregated bikeways/cycle facilities across different designs and contexts; what works for the Netherlands won't necessarily work elsewhere. Proponents argue that dedicated bike lanes have been implemented in many cities and are both popular and safe.
Bike lanes, or cycle lanes, are on-road lanes marked with paint dedicated to cycling and typically excluding all motorized traffic.
Bike paths are paths with their own right of way dedicated to cycling, though in many cases shared with pedestrians and other non-motorized traffic.
Cycle tracks / separated bike lanes
A physically marked and separated lane dedicated for cycling and typically excludes all motorized traffic with some sort of barrier.
Denmark has pioneered the concept of “bicycle superhighways” to increase the speed, safety, and comfort of bicycle commuting. The first route, C99, opened in 2012 between the Vesterbro rail station in Copenhagen and Albertslund, a western suburb. The route cost 13.4 million DKK and is 17.5 km long, built with few stops and new paths away from traffic. “Service stations” with air pumps are located at regular intervals, and where the route must cross streets, handholds and running boards are provided so cyclists can wait without having to put their feet on the ground.
A bicycle boulevard is a low speed street which has been optimized for bicycle traffic. Bicycle boulevards discourage cut-through motor vehicle traffic but allow local motor vehicle traffic. They are designed to give priority to cyclists as through-going traffic.
A greenway is a long, narrow piece of land, often used for recreation and pedestrian and bicycle user traffic, and sometimes for streetcar, light rail or retail uses.
A shared use path supports multiple modes, such as walking, bicycling, inline skating and people in wheelchairs.
Streetscape modifications to encourage cycling
There are various measures cities and regions often take on the roadway to make it more cycling friendly. Aspects of infrastructure may be viewed as either cyclist-hostile or as cyclist-friendly. Measures to encourage cycling include traffic calming; traffic reduction; junction treatment; traffic control systems to recognize cyclists and give them priority; exempt cyclists from banned turns and access restrictions; implement contra-flow cycle lanes on one-way streets; implement on-street parking restrictions; provide advanced stop lines/bypasses for cyclists at traffic signals; marking wide curb/kerb lanes; and marking shared bus/cycle lanes.
Removing traffic can be achieved by straightforward diversion or alternatively reduction. Diversion involves routing through-traffic away from roads used by high numbers of cyclists and pedestrians. Examples of diversion include the construction of arterial bypasses and ring roads around urban centres.
Indirect methods involve reducing the infrastructural capacity dedicated to moving motorized vehicles. This can involve reducing the number of road lanes, closing bridges to certain vehicle types and creating vehicle restricted zones or environmental traffic cells. In the 1970s the Dutch city of Delft began restricting private car traffic from crossing the city centre. Similarly, Groningen is divided into four zones that cannot be crossed by private motor-traffic, (private cars must use the ring road instead). Cyclists and other traffic can pass between the zones and cycling accounts for 50%+ of trips in Groningen (which reputedly has the third highest proportion of cycle traffic of any city). The Swedish city of Gothenburg uses a similar system of traffic cells.
Another approach is to reduce the capacity to park cars. Starting in the 1970s, the city of Copenhagen, which is now noted for high cycling levels, adopted a policy of reducing available car parking capacity by several per cent per year. The city of Amsterdam, where around 40% of all trips are by bicycle, adopted similar parking reduction policies in the 80s and 90s.
Direct traffic reduction methods can involve straightforward bans or more subtle methods like road pricing schemes or road diets. The London congestion charge reportedly resulted in a significant increase in cycle use within the affected area.
Two-way cycling on one-way streets
One-way street systems can be viewed as either a product of traffic management that focuses on trying to keep motorized vehicles moving regardless of the social and other impacts, such as by some cycling campaigners, or seen as a useful tool for traffic calming, and for eliminating rat runs, in the view of UK traffic planners.
One-way streets can disadvantage cyclists by increasing trip-length, delays and hazards associated with weaving maneuvers at junctions. In northern Europe countries such as the Netherlands, however, cyclists are frequently granted exemptions from one-way street restrictions, which improves cycling traffic flow while restricting motorized vehicles.
German research indicates that making one-way streets two-way for cyclists results in a reduction in the total number of collisions.
There are often restrictions to what one-way streets are good candidates for allowing two-way cycling traffic. In Belgium road authorities can in principle allow any one-way streets in 50 kilometres per hour (31 mph) zones to be two-way for cyclists if the available lane is at least 3 metres (9.8 ft) wide (area free from parking) and no specific local circumstances prevent it. Denmark, a country with high cycling levels, does not use one-way systems to improve traffic flow. Some commentators argue that the initial goal should be to dismantle large one-way street systems as a traffic calming/traffic reduction measure, followed by the provision of two-way cyclist access on any one-way streets that remain.
In general, junction designs that favour higher-speed turning, weaving and merging movements by motorists tend to be hostile for cyclists. Free-flowing arrangements can be hazardous for cyclists and should be avoided. Features such as large entry curvature, slip-roads and high flow roundabouts are associated with increased risk of car–cyclist collisions. On large roundabouts of the design typically used in the UK and Ireland, cyclists have an injury accident rate that is 14-16 times that of motorists. Research indicates that excessive sight lines at uncontrolled intersections compound these effects. In the UK, a survey of over 8,000 highly experienced and mainly adult male Cyclists Touring Club members found that 28% avoided roundabouts on their regular journey if at all possible. Cycling advocates argue for modifications and alternative junction types that resolve these issues such as reducing kerb radii on street corners, eliminating slip roads and replacing large roundabouts with signalized intersections.
Traffic signals/Traffic control systems
How traffic signals are designed and implemented directly impacts cyclists. For instance, poorly adjusted vehicle detector systems, used to trigger signal changes, may not correctly detect cyclists. This can leave cyclists in the position of having to "run" red lights if no motorized vehicle arrives to trigger a signal change. Some cities use urban adaptive traffic control systems (UTCs), which use linked traffic signals to manage traffic in response to changes in demand. There is an argument that using a UTC system merely to provide for increased capacity for motor traffic will simply drive growth in such traffic. However, there are more direct negative impacts. For instance, where signals are arranged to provide motor traffic with so called green waves, this can create "red waves" for other road users such as cyclists and public transport services. Traffic managers in Copenhagen have now turned this approach on its head and are linking cyclist-specific traffic signals on a major arterial bike lane to provide green waves for rush hour cycle-traffic. However, this would still not resolve the problem of red-waves for slow (old and young) and fast (above average fitness) cyclists. Cycling-specific measures that can be applied at traffic signals include the use of advanced stop lines and/or bypasses. In some cases cyclists might be given a free-turn or a signal bypass if turning into a road on the nearside.
In many places worldwide special signposts for bicycles are used to indicate directions and distances to destinations for cyclists. Apart from signposting in and between urban areas, mountain pass cycling milestones have become an important service for bicycle tourists. They provide cyclists with information about their current position with regard to the summit of the mountain pass.
Widening outside lanes
One method for reducing potential friction between cyclists and motorized vehicles is to provide "wide kerb", or "nearside", lanes (UK terminology) or "wide outside through lane" (U.S. terminology). These extra-wide lanes increase the probability that motorists pass cyclists at a safe distance without having to change lanes. This is held to be particularly important on routes with a high proportion of wide vehicles such as buses or heavy goods vehicles (HGVs). They also provide more room for cyclists to filter past queues of cars in congested conditions and to safely overtake each other. Due to the tendency of all vehicle users to stay in the center of their lane, it would be necessary to sub-divide the cycle lane with a broken white line to facilitate safe overtaking. Overtaking is indispensable for cyclists, as speeds are not dependent on the legal speed limit, but on the rider's capability.
Shared space schemes extend this principle further by removing the reliance on lane markings altogether, and also removing road signs and signals, allowing all road users to use any part of the road, and giving all road users equal priority and equal responsibility for each other's safety. Experiences where these schemes are in use show that road users, particularly motorists, undirected by signs, kerbs, or road markings, reduce their speed and establish eye contact with other users. Results from the thousands of such implementations worldwide all show casualty reductions and most also show reduced journey times. After the partial conversion of London's Kensington High Street to shared space, accidents decreased by 44% (the London average was 17%).
CFI argues for a marked lane width of 4.25 metres (13.9 ft). On undivided roads, width provides cyclists with adequate clearance from passing HGVs while being narrow enough to deter drivers from "doubling up" to form two lanes. This "doubling up" effect may be related to junctions. At non-junction locations, greater width might be preferable if this effect can be avoided. The European Commission specifically endorses wide lanes in its policy document on cycling promotion, Cycling: the way ahead for towns and cities.
Shared bus and cycle lanes are also a widely endorsed method for providing for cyclists. Research carried out by the Transport Research Laboratory (TRL) describes shared bus cycle lanes as "generally very popular" with cyclists. Guidance produced for Cycling England endorses bus lanes because they provide cyclists with a "direct and barrier-free route into town centres" while avoiding complications related to shared-use footways. A French survey found that 42% of cyclists were "enthusiasts" for shared bus-bike lanes, versus 33% who had mixed opinions, and 27% who opposed them. Many cycling activists view these as being more attractive than cycle paths, while others object to being close to bus exhausts, a problem easily avoided through replacing exhaust buses with electric ones.
As of 2003, mixed bus-cycle lanes accounted for 118 kilometres (73 mi) of the 260 kilometres (160 mi) of cycling facilities in Paris. The city of Bordeaux, France, has 40 kilometres (25 mi) of shared bus-bike lanes. The UK city of Bristol, a showcase bus priority corridor, re-allocated 14 kilometres (8.7 mi) of road space, which resulted in more space for cyclists and increased cycling. The opposite happened in London following the removal of a bus lane on the Kew Bridge, despite an overall increase in cycling throughout the city.
In addition, it is arguably easier, politically speaking, to argue for funding of joint facilities rather than separately asking for cycling facilities and bus-only lanes. Bus lane proposals often run into opposition from cyclists because creating space for bus lanes generally results in narrowing the other lanes shared by cars and cyclists. Incidentally, the TRL reports that cyclists and bus drivers tend to have low opinions of one another. In some cities, arrangements work successfully with bus companies and cyclists' groups ensure communication and understanding between the two groups of road users.
Bicycle parking/storage arrangements
As secure and convenient bicycle parking is a key factor in influencing a person's decision to cycle, decent parking infrastructure must be provided to encourage the uptake of cycling. Decent bicycle parking involves weather-proof infrastructure such as lockers, stands, manned or unmanned bicycle parks, as well as bike parking facilities within workplaces to facilitate bicycle commuting. It also will help if certain legal arrangements are put into place to enable legitimate ad hoc parking, for example to allow people to lock their bicycles to railings, signs and other street furniture when individual proper bike stands are unavailable.
Other trip end facilities
Some people need to wear special clothes such as business suits or uniforms in their daily work. In some cases the nature of the cycling infrastructure and the prevailing weather conditions may make it very hard to both cycle and maintain the work clothes in a presentable condition. It is argued that such workers can be encouraged to cycle by providing lockers, changing rooms and shower facilities where they can change before starting work.
Theft reduction measures
The theft of bicycles is one of the major problems that slow the development of urban cycling. Bicycle theft discourages regular cyclists from buying new bicycles, as well as putting off people who might want to invest in a bicycle.
Several measures can help reduce bicycle theft:
- Bicycle registration to enable recovery if stolen
- Making cyclists aware of antitheft devices and their effective use
- Mounting sting operations to catch thieves
- Offering safe bicycle parking facilities such as guarded bicycle parking (manned or with camera surveillance) or bicycle lockers
- Promoting devices to enable remote tracking of a bicycle's location
- Targeting cycle thieves
- Using Folding bicycles which can be safely stored (for example) in cloakrooms or under desks.
Certain European countries apply such measures with success, such as the Netherlands or certain German cities using registration and recovery. Since mid-2004, France has instituted a system of registration, in some places allowing stolen bicycles to be put on file in partnership with the urban cyclists' associations. This approach has reputedly increased the stolen bicycle recovery rate to more than 40%. By comparison, before the commencement of registration, the recovery rate in France was about 2%.
In some areas of the United Kingdom, bicycles fitted with location tracking devices are left poorly secured in theft hot-spots. When the bike is stolen, the police can locate it and arrest the thieves. This sometimes leads to the dismantling of organized bicycle theft rings, as bike theft generally enjoys a very low priority with the police.
Integration with public transit
Cycling can often be integrated successfully with other transport modes. For example, in the Netherlands and Denmark a large number of train journeys may start by bicycle. In 1991, 44% of Dutch train travelers went to their local station by bicycle and 14% used a bicycle at their destinations. The key ingredients for this are claimed to be:
- an efficient, attractive and affordable train service
- secure bike parking at train stations
- a quick and easy bicycle rental system for commuters, the OV-bicycle scheme, at train stations
- a town planning policy that results in a sufficient proportion of the potential commuter population (e.g. 44%) living/working within a reasonable cycling distance of the train stations.
It has been argued in relation to this aspect of Dutch or Danish policy that ongoing investment in rail services is vital to maintaining their levels of cycle use.
An often forgotten major success story is the integration of cycling and public transport is Japan. Starting in 1978, Japan expanded bicycle parking supply at railway stations from 598,000 spaces in 1977 to 2,382,000 spaces in 1987. As of 1987, Japanese provisions included 516 multi-story garages for bicycle parking.
In January 2007, the European parliament adopted a motion decreeing that all international trains must carry bicycles. In some cities, bicycles may also be carried on local trains, trams and buses so that they may be used at either end of the trip. The Rheinbahn transit company in Düsseldorf permits bicycle carriage on all its bus, tram and train services at any time of the day, while in Munich it is strictly forbidden, under threat of calling the police. In France, the prestigious TGV high-speed trains are even having some of their first class capacity converted to store bicycles. There have also been schemes, such as in Victoria, British Columbia, Acadia, and Canberra, Australia to provide bicycle carriage on buses using externally mounted bike carriers.
In Edmonton, Alberta, Canada, all bus routes have externally mounted carriers for bicycles. All public transit buses in Chicago and suburbs allow up to two bikes at all times. The same is true of Grand River Transit buses in the Region of Waterloo, Ontario, Canada. Trains allow bikes with some restrictions. Where such services are not available, some cyclists get around this restriction by removing their pedals and loosening their handlebars as to fit into a box or by using folding bikes that can be brought onto the train or bus like a piece of luggage. The article on buses in Christchurch, New Zealand lists 27 routes with bike racks.
However, there are strong cultural variations in how cycling is treated in such situations. For instance in the Irish university city of Galway, the same town that suggested cyclists dismount and walk across each intersection, the secure parking of bikes is forbidden within the grounds of the central train station. However, cut-price car parking is available for motorists holding a valid train ticket.
A bicycle sharing system, public bicycle system, or bike share scheme, is a service in which bicycles are made available for shared use to individuals on a very short term basis. Bike share schemes allow people to borrow a bike from point "A" and return it at point "B". Many of the bicycle sharing systems are on a subscription basis.
