"Bicycle-friendly" describes policies and practices which may help some people feel more comfortable about traveling by
bicyclewith other traffic. The level of "bicycle-friendliness" of an environment can be influenced my many factors resulting from "town planning" and "cycling infrastructure" decisions.
Assuming people prefer to get to their destination quickly,
town planningand zoningmay have an impact on whether schools, shops, public transport interchanges and other destination are within a reasonable cycling distance of the areas where people live. If urban form influences these issues, then compact and circular settlement patterns may promote cycling. Alternatively, the low-density, non-circular (i.e., linear) settlement patterns characteristic of urban sprawltends to discourage cycling.Fact|date=March 2008 In 1990, the Dutch adopted the "ABC" guidelines, specifically limiting developments that are major attractants to locations that are readily accessible by non-car users.Legislative Tools for Preserving Town Centres and Halting the Spread of Hypermarkets and Malls Outside of Cities: Land Use Legislation and Controls of Conflicts of Interest in Land Use Decision Making, by Ken Baar, Ph.D. Institute for Transport and Development Policy, New York NY 10001, 2002]
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 as transport. Settlements that provide a dense roads network consisting of interconnected
streets will tend to encourage cycling.
In contrast, other communities may use a
cul-de-sacbased, housing estate/ housing subdivisionmodel where minor roads are disconnected and only feed into a street hierarchyof progressively more "arterial" type roads. Designs that propose to resolve the contradiction between the cul-de-sac and the traditional interconnected network, such as the Fused Grid, have been proposed and built with varying levels of success. [Durning 1996 cited in Safe Travels, Evaluating Mobility Management Traffic Safety Impacts by Todd Litman & Steven Fitzroy Victoria Transport Policy Institute, 1250 Rudlin Street, Victoria, BC, V8V 3R7, CANADA]
In the UK, the principle of 'filtered permeability' has been proposed in some Government guidance, to maximise the ease of movement of cyclists and pedestrians, whilst constraining it for motor vehicles (see:
Permeability (spatial and transport planning).
infrastructurecomprises the public ways available to cyclists. This includes the network of public roads used by other road vehicleusers, minus those roads from which cyclists have been banned (most motorways or freeways), plus additional routes that are not available to other types of vehicle, such as cycle tracks and (in some jurisdictions) sidewalks.
Aspects of the cycling infrastructure may be viewed as either cyclist-hostile or as cyclist-friendly. In general, roads infrastructure based on prioritising certain routes in an attempt to create a state of constant "flow" for vehicles on that route, will tend to be hostile to those not on that route. In 1996, the British Cyclists Touring Club (CTC) and the Institute for Highways and Transportation jointly produced the document "Cycle-friendly infrastructure: Guidelines for planning and design". [http://www.iht.org/publications/technical/cyclefriendly.asp Cycle-Friendly Infrastructure: Guidelines for Planning and Design] , Institution of Highways and Transportation, Cyclists Touring Club, 1996.] This defined a hierarchy of measures for cycling promotion in which the goal is to convert a more or less cyclist-hostile roads infrastructure into one which encourages and facilitates cycling.
The CTC/IHT hierarchy
# Traffic reduction. Can traffic levels, particularly of heavy vehicles, be reduced?
# Traffic calming. Can speed be reduced and driver behaviour modified?
# Junction treatment and traffic management. These measures include:
#* Urban traffic control systems designed to recognise cyclists and give them priority.
#* Exempt cyclists from banned turns and access restrictions.
#* Provide contra-flow cycle lanes on one-way streets.
#* Implement on-street parking restrictions.
advanced stop lines/bypasses for cyclists at traffic signals.
#* Junction alterations, signalise roundabouts, cycle-friendly junction design.
# Redistribution of the carriageway -such as by marking wide kerb lanes or shared bus/cycle lanes.
Cycle lanes and cycle tracks. Having considered and implemented all the above, what cycle tracks or cycle lanes are considered necessary?
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.
Traffic reduction can involve direct or indirect methods. A proven indirect method of reducing motor traffic, and facilitating cyclist and pedestrian use, is to adopt the
shared spacesystem. This system, by giving equal priority to all road users, and by removing conventional road markings, road signs and road conventions, capitalises on the tendency for all road users to respect and trust each-other when they are interacting on an equal basis. No explicit, or even implicit priority is given to traffic travelling along the road, so with no assumptions of priority being possible, all road users need to be aware of all other road users at all times.New Road in Brightonwas remodelled using this philosophy, and the results were a 93% reduction in motor traffic and a 22% increase in cycling traffic. [cite web |title=New Road City Centre Shared Space, Brighton (December 2007) |work=Scheme of the Month: January 2008 |publisher=Cycling England |url=http://www.cyclingengland.co.uk/scheme-of-the-month.php |accessdate=2008-03-18] Other indirect methods involve reducing the infrastructural capacity dedicated to moving or storing road vehicle. 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 Delftbegan restricting private car traffic from crossing the city centre [ [http://www.urban.nl/childstreet2005/downloads/StevenSchepel-CF..pdf Woonerf revisited] Delft as an example, Steven Schepel, Childstreet2005 conference, Delft 2005 (Accessed 2007-02-21] .

The Swedish city of Gothenburguses a similar system of traffic cells.

(Accessed 2007-02-02)] Starting in the 1970s, the city of Copenhagen, which is noted for high cycling levels, adopted a policy of reducing available car parking capacity by several per cent a year. The city of Amsterdam, where around 40% of all trips are by bicycle, [ [http://www.ivv.amsterdam.nl DIVV Amsterdam] ] adopted similar parking reduction policies in the 80s and 90s.
Direct traffic reduction methods can involve straightforward bans or more subtle methods like
road pricingschemes or road diets. The London congestion chargereportedly resulted in a significant increase in cycle use within the affected area.Fact|date=March 2008
Speed reduction has traditionally been attempted by the introduction of statutory
speed limits. Traffic speeds of 30 km/h (20 mph) and lower are said to be more desirable on urban roads with mixed traffic. [Speed reduction, traffic calming or cycling facilities: a question of what best achieves the goals?, Michael Yeates, Convenor, Cyclists Urban Speed limit Taskforce, Bicycle Federation of Australia, Velomondial Conference Proceedings, Amsterdam 2000] The Austrian city of Graz, which has achieved steady growth in cycling, has applied 30 km/h limits to 75% its streets since 1994 [The Graz traffic calming model and its consequences for cyclists, Manfred Hoenig, Department of transportation, City Council Graz, Velomondial Conference Proceedings, Amsterdam 2000] . Speed limits which are set below the speed that most motorists perceive to be reasonable for the given road require additional measures to improve compliance. Attempts to improve speed limit observance are usually by either education, enforcement or road engineering. "Education" can mean publicity campaigns or targeted road user training. Speed limit "Enforcement" techniques include: direct police action, automated systems such as speed cameras or vehicle activated signs or traffic lights triggered by traffic exceeding a preset speed threshold. One cycling expert argues for placing direct restrictions on motor-vehicle speed and acceleration performance.

Recent implementations of
shared spaceschemes have delivered significant traffic speed reductions. The reductions are sustainable, without the need for speed limits or speed limit enforcement. In Norrköping, mean traffic speeds have dropped from 21 to 16 km/h(13 to 10 mph) since the implementation of such a scheme.

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. [ [http://galwaycycling.org/archive/info/roundabouts.html Multilane Roundabouts] , An Information Sheet, Galway Cycling Campaign, February 2001] Research indicates that excessive sightlines at uncontrolled intersections compound these effects.

Cyclists' Touring Clubmembers found that 28% avoided roundabouts on their regular journey if at all possible. [Cyclists and Roundabouts-A review of literature, Allot and Lomax, 1991]
Traffic signals/Traffic control systems
traffic signals are designed and implemented directly impacts cyclists. [Priority for cycling in an urban traffic control system, Stephen D. Clark, Matthew W. Page, Institute for Transport Studies, University of Leeds, Velomondial Conference Proceedings, Amsterdam 2000] For instance, poorly adjusted vehicle detector systems, used to trigger signal changes, may not correctly detect cyclists. Traffic managers in Copenhagen link cyclist-specific traffic signals on a major arterial bike lane to provide green waves for rush hour cycle-traffic. [ [http://www.cyclenetwork.org.uk/news/ccn85.pdf Green wave for cycles] , Cycle Campaign Network News, No 85, November 2006] Cycling-specific measures that can be applied at traffic signals include the use of advanced stop lines and/or bypasses.
The frequency with which lights change is important to cyclists who may conserve energy by anticipating green lights ahead ie. the shorter the interval the better for cyclists
Coexistence with other road users
Several methods of altering or reallocationg the carriageway (UK) or roadway (USA) to decrease the potential for social friction during overtaking and passing have been added to many of the manuals used by designers.
Shared spaceschemes, which are characterised by the removal of road markings, signs and signals, give all road users equal priority and equal responsibility for each others 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.cite news |title=Rip out the traffic lights and railings. Our streets are better without them |author=Simon Jenkins |date= 2008-02-29|publisher=Guardian News and Media |work=The Guardian |url=http://www.guardian.co.uk/commentisfree/2008/feb/29/guardiancolumnists |accessdate=2008-03-20] Following the partial conversion of London's Kensington High Street to "shared space", accidents were reduced there by 44% (the London average was 17%).
Extra wide lanes
Wide kerb (nearside) lanes (UK) or Wide outside through lanes (USA) help motorists pass slower cyclists without having to decrease speed or change
lanes. [cite web
title=Wide Outside Through Lanes: Effective Design of Integrated Passing Facilities
author=Steven G. Goodridge Ph.D.
quote=The function of wide outside through lanes as passing facilities is presented.
format=PDF] This method is held by somewho to be particularly important on routes with a high proportion of wide vehicles, such as
buses or heavy trucks. These lanes also provide more room for cyclists to filter past queues of other vehicles in congested conditions. The use of such lanes is specifically endorsed by "Cycling: the way ahead for towns and cities", the European Commissionpolicy document on cycle promotion. [ [http://ec.europa.eu/environment/cycling/cycling_en.pdf Cycling: the way ahead for towns and cities] , European Commission, 1999]
"Cycle friendly infrastructure" argues for a marked lane width of 4.25 m (14 ft). It is arguedwho that, on undivided roads, this width provides cyclists with adequate clearance from passing wide vehicles while being sufficiently narrow to deter motorists from attempting to “double up” and 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.
Cycle lanes and cycle tracks
Roads or paths which are not suitable for motorized traffic can benefit cyclists by providing more pleasant and efficient ways on which to travel than the main
roadnetwork. Examples include green ways and routes through pedestrian precincts. In contrast are facilities within the right-of-way of public roads which are intended to separate cyclists as a class from other travelers (i.e., to segregate them). While segregated cycle facilitiessuch as cycle lanes and cycle tracks are often advocated as a means of reducing anxiety about cycling near motorists, their effects on safety, cycling promotion, and the right of individuals to travel freely is controversial.
hared Bus lanes
The sharing of Bus lanes by both bus and bicycle traffic has been described as "generally very popular" with cyclists.Cycling in bus lanes, Reid S and Guthrie N TRL Report 610, Transport Research Laboratory 2004] Guidance produced for "Cycling England" endorses
bus lanes as providing cyclists with a "direct and barrier free route into town centres" and as avoiding the difficulties associated with other provisions such as shared-use footways. [A.10 Bus Lanes and Bus Stops Cycling England design guidelines 2007] According to a French survey 42% of cyclists described themselves as "enthusiasts" for shared bus bike lanes versus 33% who were of mixed opinion and 27% who were opposed. [http://www.fubicy.org/ancien_site/velocite/articles/velocite-80-tc&velo-1.pdf La complémentarité entre vélo et transport public] Vélocité - la revue du cycliste urbain N° 79, janv. / fév. 2005] Many cycling activists view these as being more attractive than cycle paths, while others object to being in close proximity to bus exhausts.
As of 2003, mixed bus/cycle lanes accounted for 118km of the 260km of cycling facilities in
Paris. [ [http://www.velo.free.fr/update/la%20place%20du%20velo%20en%20ville/Intervention%2023%20sept%2004%20mairie18%20pour%20site.pdf The bicycle's place in town] Seminar organised by the Mayor's Office of the 18th District, Paris, September 2004] The French city of Bordeauxhas 40km of shared bus cycle lanes.

[Review of procedures associated with the development and delivery of measures designed to improve safety and convenience for cyclists Transport for London, January 2005] In addition, it is arguably easier, politically speaking, to argue for funding of joint facilities rather than the additional expense of both segregated cycling facilities and bus-only lanes.

Translated here [http://www.bikexprt.com/bikepol/facil/lanes/adfcbus.htm] ]
In some instances. bus lane proposals have run into vehement opposition from cyclists reps - a typical theme is the perceived generation of conflict due to the narrowing of other lanes already shared by cars/cyclists so as to create space for the bus lanes [ [ http://www.camcycle.org.uk/campaigning/letters/2003/L03007MiltonRoadBusLaneObjection.pdf Letter of Objection to Bus lanes on Wilton Road] Cambridge Cycle Campaign, September 2003] The TRL reports that cyclists and bus drivers tend to have low opinions of each other There have been reports in
Dublinof conflict as cyclists choose to cycle in the bus lanes and a bus driver apparently expected them to use adjacent cycle tracks instead.

Bicycle parking/storage arrangements
parkingis argued to be a key factor influencing the decision to cycle. [ [http://www.tfhrc.gov/safety/pedbike/pubs/05085/chapt17.htm Lesson 17: Bicycle Parking and Storage] , Federal Highway Administration University Course on Bicycle and Pedestrian Transportation Publication No. FHWA-HRT-05-133 July 2006] To be considered secure, the parking must be of a suitable design: allowing the bicycle to be locked via the frame. A readily observable location can also permit so-called passive security from passers-by. Weather protection is also desirable. As a rule, where cycling is encouraged as an alternative to motoring, efforts are made to make bicycle parking more convenient and attractive to use than nearby car parking arrangements. This usually means providing a wide distribution of visible, clearly designated parking spots, close to the entrances of destinations being served.
Storage rooms or bicycle lockers may also be provided. In some cases large concentrations of bike parking may be more appropriate, sometimes being supervised and sometimes charging a fee. Examples include large bike parks at
public transportinterchanges such as railway, subway, tramor busstationsBicycle Access to Public Transportation: Learning from Abroad by Michael Replogle, Journal of the Institute for Transportation Engineers, December 1992] where they may be useful in Mixed-mode commuting.
Conversely, where cycling is seen as an unwelcome or inappropriate activity, bicycle parking may simply not be provided or else deliberately placed at awkward, out-of-sight, locations away from public view.

Other trip end facilities
Some people need to wear special clothes such as
business suits or uniformsin 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.
