A roundabout, also known as a rotary or traffic circle, is a type of circular intersection or junction in which road traffic is permitted to flow in one direction around a central island, and priority is typically given to traffic already in the junction.
Houten is a municipality in the Netherlands, in the province of Utrecht.
An intersection or an at-grade junction is a junction where two or more roads converge, diverge, meet or cross at the same height, as opposed to an interchange, which uses bridges or tunnels to separate different roads. Major intersections are often delineated by gores and may be classified by road segments, traffic controls and lane design.
The Kingsway tramway subway is a cut-and-cover Grade II Listed tunnel in central London, built by the London County Council, and the only one of its kind in Britain. The decision in 1898 to clear slum districts in the Holborn area provided an opportunity to use the new streets for a tramway connecting the lines in the north and south. Following the pattern of tramways in New York and Boston, it was decided to build this as an underground connection.
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.
In civil engineering, grade separation is a method of aligning a junction of two or more surface transport axes at different heights (grades) so that they will not disrupt the traffic flow on other transit routes when they cross each other. The composition of such transport axes does not have to be uniform; it can consist of a mixture of roads, footpaths, railways, canals, or airport runways. Bridges, tunnels, or a combination of both can be built at a junction to achieve the needed grade separation.
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.
The Milton Keynes redway system is an over 200 miles network of shared use paths for cyclists and pedestrians in Milton Keynes, Buckinghamshire, England. It is generally surfaced with red tarmac, and criss-crosses most of the city.
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 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.
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.
The Ringwood - Belgrave Rail Trail is a shared use path for cyclists and pedestrians, which follows the Belgrave railway line from the Mullum Mullum Creek Trail in Ringwood to Belgrave railway station in Belgrave, in the outer eastern suburbs of Melbourne, Victoria, Australia.
The design of road signs in Poland is regulated by Regulation of the Ministers of Infrastructure and Interior Affairs and Administration on road signs and signals. The Annex 1 to the regulation describes conditions related to usage of the road signs – size, visibility, colors and light reflections, typeface and text, criteria of choosing the type of foil to signs faces, colorful specimens and schematics.
Bike paths in Sydney, New South Wales, Australia, vary widely, with the majority either shared cycle and pedestrian paths or on road paths, and a small number of separated cycleways. In 2009 the Sydney Morning Herald reported that "Sydney's cycleways are not so much an organised network as a fragmented collection of winding paths and half-finished ideas. Most were built or designed when cycling was viewed as a pleasant pastime rather than a practical form of travel and are now poorly suited to commuting."
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.
Road signs in Hong Kong are standardised by the Transport Department. Due to being a former British territory, the road signage in Hong Kong is similar to road signs in the United Kingdom, with the addition of Traditional Chinese characters.
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.
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 help pedestrians and cyclists be and feel safer at road junctions.
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.
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.
