Road traffic safety refers to the methods and measures used to prevent road users from being killed or seriously injured. Typical road users include pedestrians, cyclists, motorists, vehicle passengers, and passengers of on-road public transport.
Utility cycling encompasses any cycling done simply as a means of transport rather than as a sport or leisure activity. It is the original and most common type of cycling in the world. Cycling mobility is one of the various types of private transport and a major part of individual mobility.
A bus bulb, also called a bus boarder, bus border, bumpout, bus cape, or a kerb outstand is an arrangement by which a sidewalk or pavement is extended outwards for a bus stop; typically the bus bulb replaces roadway that would otherwise be part of a parking lane. With bus bulbs or boarders, a bus can stay in its traffic lane to discharge and pick up passengers, instead of having to pull over to the curb.
Cycling in Melbourne is an important mode of transport, fitness, sport and recreation in many parts of the city. After a period of significant decline through the mid to late 20th century, additional infrastructure investment, changing transport preferences and increasing congestion has resulted in a resurgence in the popularity of cycling for transport. This is assisted by Melbourne's natural characteristics of relatively flat topography and generally mild climate.
Vehicular cycling is the practice of riding bicycles on roads in a manner that is in accordance with the principles for driving in traffic, and in a way that places responsibility for safety on the individual.
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 as well as mixed-mode environments and how both of these examples can be made to work safely. In jurisdictions such as the United States it is often practiced in conjunction with planning for pedestrians as a part of active transportation planning.
Shared space is an urban design approach that minimises the segregation between modes of road user. This is done by removing features such as curbs, road surface markings, traffic signs, and traffic lights. Hans Monderman and others have suggested that, by creating a greater sense of uncertainty and making it unclear who has priority, drivers will reduce their speed, in turn reducing the dominance of vehicles, reducing road casualty rates, and improving safety for other road users.
A cycle track or cycleway (British) or bikeway, sometimes historically referred to as a sidepath, is a separate route for cycles and not motor vehicles. In some cases cycle tracks are also used by other users such as pedestrians and horse riders. A cycle track can be next to a normal road, and can either be a shared route with pedestrians or be made distinct from both the pavement and general roadway by vertical barriers or elevation differences.
Cycling in Sydney, New South Wales, Australia takes place for recreation, commuting and as a sport. Sydney has a hilly topography and so may require a slightly higher level of fitness from cyclists than flatter cities such as Melbourne and Canberra. Sydney depends heavily on motor vehicles where traffic and public transport operate at capacity. This means that cyclist are often competing with motorists for limited space on busier roads, and for limited government resources for expenditure on road infrastructure. In its favour, Sydney has a generally mild climate and there are active cycling groups.
Cycling in Perth, Western Australia is common on the roads and paths for recreation, commuting and sport. Between 1998 and 2009 the number of cyclists in Perth increased 450%.
Cycling in Auckland is a mode of transport in Auckland, New Zealand. The dominance of the car in the city, the negative attitudes of car drivers and general changes in transport patterns have made it a very marginal transport mode in the early 21st century, with remaining cyclists often riding for leisure and sports purposes.
Cycling in the Australian state of New South Wales is a common form of recreation.
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.
Cycling in Denmark is both a common and popular recreational and utilitarian activity. Bicycling infrastructure is a dominant feature of both city and countryside infrastructure with segregated dedicated bicycle paths and lanes in many places and the network of 11 Danish National Cycle Routes extends more than 12,000 kilometres (7,500 mi) nationwide. Often bicycling and bicycle culture in Denmark is compared to the Netherlands as a bicycle-nation.
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.
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.
Two-wheelers are a common sight and widely used in Japan. Of these, bicycles and scooters are the most common.
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.
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.
