Bicycle transportation planning and engineering are the disciplines related to transportation engineering and transportation planning concerning bicycles as a mode of transport and the concomitant study, design and implementation of cycling infrastructure. It includes the study and design of dedicated transport facilities for cyclists (e.g. cyclist-only paths) as well as mixed-mode environments (i.e. where cyclists share roads and paths with vehicular and foot traffic) and how both of these examples can be made to work safely. [1] In jurisdictions such as the United States it is often practiced in conjunction with planning for pedestrians as a part of active transportation planning. [2]

Networks, signage and maps

Most national cycling route networks have long-distance named routes, rather like highways. However, the international numbered-node cycle network has a modular design that enables arbitrary routes using simple signage. Both aim to minimize map use with plentiful signs.

Cycle networks of routes can be developed in co-ordination with cycle maps. Co-ordination can be local or national (the numbered-node cycle network has national co-ordination in some countries, and local co-ordination in others).

Bikeways

Some examples of the types of bikeways under the purview of bicycle transportation engineers include partially segregated infrastructure in-road such as bike lanes, buffered bike lanes; physically segregated in-road such as cycle tracks; bike paths with their own right-of-way; and shared facilities such as bicycle boulevards, shared lane markings, advisory bike lane, road shoulders, wide outside lanes, shared street schemes, and any roadways with legal access for cycling.

In roadway

NACTO guidelines state "desired width for a cycle track should be 5 feet (1.5 m). In areas with high bicyclist volumes or uphill sections, the desired width should be 7 feet (2.1 m)". CROW standard width for one way cycle paths in the Netherlands is a minimum of 2.5 m (8′). For bidirectional use the minimum is 3.5 m (11′).

Unsegregated

Partially segregated

Segregated

Barriers

Options for barriers are soft-hit posts, raised curb or traffic barriers.

Off road

Bike freeway

Intersections and signals

Bicycle transportation engineers also are involved in improving intersections/junctions and traffic lights. Advanced stop lines are one example of road markings on mixed mode shared space as cycling infrastructure.

Other infrastructure

Road diets, curb extension, improving the road surface; building bicycle parking such as bicycle locks, bicycle stands, lockers.

Legislation

in California new bikeway design standards were last adopted in 1976. Those designs were adapted by the Association of American State Highway and Transportation Officials (AASHTO) to become the AASHTO Guide for Bicycle Facilities, which is followed in the USA.

<span class="mw-page-title-main">Bike path</span> Bikeway separated from motorized traffic

A bike path or a cycle path is a bikeway separated from motorized traffic and dedicated to cycling or shared with pedestrians or other non-motorized users. In the US a bike path sometimes encompasses shared use paths, "multi-use path", or "Class III bikeway" is a paved path that has been designated for use by cyclists outside the right of way of a public road. It may or may not have a center divider or stripe to prevent head-on collisions. In the UK, a shared-use footway or multi-use path is for use by both cyclists and pedestrians.

<span class="mw-page-title-main">Bike lane</span> Road traffic lane for cyclists

Bike lanes (US) or cycle lanes (UK) are types of bikeways (cycleways) with lanes on the roadway for cyclists only. In the United Kingdom, an on-road cycle-lane can be firmly restricted to cycles or advisory. In the United States, a designated bicycle lane or class II bikeway (Caltrans) is always marked by a solid white stripe on the pavement and is for 'preferential use' by bicyclists. There is also a class III bicycle route, which has roadside signs suggesting a route for cyclists, and urging sharing the road. A class IV separated bike way (Caltrans) is a bike lane that is physically separate from motor traffic and restricted to bicyclists only.

John Forester was an English-American industrial engineer, specializing in bicycle transportation engineering. A cycling activist, he was known as "the father of vehicular cycling", for creating the Effective Cycling program of bicycle training along with its associated book of the same title, and for coining the phrase "the vehicular cycling principle" – "Cyclists fare best when they act and are treated as drivers of vehicles". His published works also included Bicycle Transportation: A Handbook for Cycling Transportation Engineers.

A bicycle boulevard, sometimes referred to as a neighborhood greenway, neighborway, neighborhood bikeway or neighborhood byway is a type of bikeway composed of 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 bicyclists as through-going traffic. They are intended as a low-cost, politically popular way to create a connected network of streets with good bicyclist comfort and/or safety.

<span class="mw-page-title-main">Cycling in the Netherlands</span> Dutch mode of transport

Cycling is a 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 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 than car routes.

<span class="mw-page-title-main">Cycle track</span> Bikeway between a road and sidewalk, protected by barriers

A cycle track, separated bike lane or protected bike lane is an exclusive bikeway that has elements of a separated path and on-road bike lane. A cycle track is located within or next to the roadway, but is made distinct from both the sidewalk and general purpose roadway by vertical barriers or elevation differences.

<span class="mw-page-title-main">Cycling in New York City</span>

Cycling in New York City is associated with mixed cycling conditions that include dense urban proximities, relatively flat terrain, congested roadways with stop-and-go traffic, and streets with heavy pedestrian activity. The city's large cycling population includes utility cyclists, such as delivery and messenger services; cycling clubs for recreational cyclists; and increasingly commuters. Cycling is increasingly popular in New York City; in 2018 there were approximately 510,000 daily bike trips, compared with 170,000 daily bike trips in 2005.

<span class="mw-page-title-main">Cycling in Toronto</span>

Toronto, Ontario, like many North American cities, has slowly been improving its cycling infrastructure. The number of cyclists in Toronto has been increasing progressively, particularly in the city's downtown core. As cycling conditions improve, a cycling culture has grown and alternatives such as automobiles are seen as less attractive. The politics of providing resources for cyclists, particularly dedicated bike lanes, has been contentious, particularly since the 2010s.

<span class="mw-page-title-main">Cycling in Copenhagen</span> Means of transportation in Copenhagen, Denmark

Cycling in Copenhagen is – as with most cycling in Denmark – an important mode of transportation and a dominating feature of the cityscape, often noticed by visitors. The city offers a variety of favourable cycling conditions — dense urban proximities, short distances and flat terrain — along with an extensive and well-designed system of cycle tracks. This has earned it a reputation as one of the most bicycle-friendly cities in the world. Every day 1.2 million kilometres are cycled in Copenhagen, with 62% of all citizens commuting to work, school, or university by bicycle; in fact, almost as many people commute by bicycle in greater Copenhagen as do those cycle to work in the entire United States. Cycling is generally perceived as a healthier, more environmentally friendly, cheaper, and often quicker way to get around town than by using an automobile.

<span class="mw-page-title-main">Cycling in Canada</span> Overview of cycling in Canada

Cycling in Canada is experienced in various ways across a geographically huge, economically and socially diverse country. Among the reasons for cycling in Canada are for practical reasons such as commuting to work or school, for sports such as road racing, BMX, Mountain bike racing, freestyle BMX, as well as for pure recreation. The amount and quality of bicycle infrastructure varies widely across the country as do the laws pertaining to cyclists such as bicycle helmet laws which can differ by province.

<span class="mw-page-title-main">Cycling infrastructure</span> Facilities for use by cyclists

Cycling infrastructure is all infrastructure cyclists are allowed to use. Bikeways include bike paths, bike lanes, cycle tracks, rail trails and, where permitted, sidewalks. Roads used by motorists are also cycling infrastructure, except where cyclists are barred such as many freeways/motorways. It includes amenities such as bike racks for parking, shelters, service centers and specialized traffic signs and signals. The more cycling infrastructure, the more people get about by bicycle.

The history of cycling infrastructure starts from shortly after the bike boom of the 1880s when the first short stretches of dedicated bicycle infrastructure were built, through to the rise of the automobile from the mid-20th century onwards and the concomitant decline of cycling as a means of transport, to cycling's comeback from the 1970s onwards.

<span class="mw-page-title-main">Shared-use path</span> Pathway for pedestrians and cyclists

A shared-use path, mixed-use path or multi-use pathway is a path which is "designed to accommodate the movement of pedestrians and cyclists". Examples of shared-use paths include sidewalks designated as shared-use, bridleways and rail trails. A shared-use path typically has a surface that is asphalt, concrete or firmly packed crushed aggregate. Shared-use paths differ from cycle tracks and cycle paths in that shared-use paths are designed to include pedestrians even if the primary anticipated users are cyclists.

<span class="mw-page-title-main">Protected intersection</span> At-grade road junction in which cyclists and pedestrians are separated from cars

A protected intersection or protected junction, also known as a Dutch-style junction, is a type of at-grade road junction in which cyclists and pedestrians are separated from cars. The primary aim of junction protection is to make pedestrians and cyclists safer and feel safer at road junctions.

<span class="mw-page-title-main">Safety of cycling infrastructure</span> Overview of bicycle safety concerns

There is debate over the safety implications of cycling infrastructure. 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.

<span class="mw-page-title-main">Bikeway controversies</span>

Controversies have surrounded dedicated cycling routes in cities. Some critics of bikeways argue that the focus should instead be placed on educating cyclists in road safety, and others that safety is better served by using the road space for parking. There is debate over whether cycle tracks are an effective factor to encourage cycling or whether other factors are at play.

<span class="mw-page-title-main">Bicycle highway</span> Direct long-distance separated cycle path for utility cycling, without big intersections or detours.

A bicycle highway, also known as a cycling superhighway, fast cycle route or bike freeway, is an informal name for a bicycle path that is meant for long-distance traffic. There is no official definition of a bicycle highway. The characteristics of a cycle motorway mentioned by authorities and traffic experts include an absence of single-level intersections with motorized traffic, a better road surface and the absence of traffic lights. Bicycle highways are mentioned in connection with traffic jam. Owing to higher average speeds than normal cycling infrastructure, they provide an alternative to the car in commuter traffic. Often a cycle motorway follows the route of a railway or other linear infrastructure.
