In highway engineering, capacity refers to the ability of a road or street to carry motor vehicles (or, more importantly, people).

Capital (spending) refers to an amount spent on improving, or building, an asset. With regards to cycling, this might typically involve investment in the construction of new cycleways, improved junctions, or links between urban areas.

Cargo Bike

A catch-all term for a wide variety of adapted cycles, designed for carrying heavy or bulky loads, or passengers, including children. They can come in either two-wheeled, three-wheeled, or four-wheeled form, with or without e-assistance.


The section of the highway that is generally used by motor vehicles and cycles - alternatively, 'the road').

Carriageway narrowing

A form of design used to encourage slower traffic and to provide better (usually wider) pavement facilities for pedestrians, and indeed cycling infrastructure.

Centre line

A dashed marking used as a lane divider, or to indicate that a road, or a cycle path, has two-way traffic on it.


A chaincase is a device that encloses the chain on a bicycle. It's a practical feature that is ubiquitous on bicycles ridden for transport in the Netherlands and Denmark. 


'Channel' refers to the area adjacent to a kerb line, designed to collect water and guide it to drains.

Christiania bike

A manufacturer of cargo bikes in Denmark - most often seen as tricycles, and popular with businesses. 


The Chartered Instititute of Highways and Transportation.


The "Community Infrastructure Levy".


Clutter is those elements both visual and physical that detract from the simplicity of a street design. Sometimes used as an argument for naked streets, but also for more simply reducing unnecessary obstructions by other changes in design e.g.

Coaster brake

A coaster brake is a back pedal brake, typically found on bicycles ridden for transport in the Netherlands and Denmark. 


Also called 'Coherence'. One of the five main demands used to measure the quality of cycling infrastructure (the others are safety


Cycling infrastructure should be surfaced in one consistent colour, as much as possible, to provide clarity, visual priority, legibility and continuity. 

Combined Traffic

A term used to refer to cycles and motor traffic being 'combined' on the carriageway, i.e. without any separate cycle provision. 'Combined traffic' should only occur in low speed, low traffic environments.


One of the five main demands used to measure the quality of cycling infrastructure (the others are safetydir

Compact Roundabout

Also known as a Contiental Roundabout, this describes the concept of a reduced radius in the centre of a roundabout creating a layout in which motor vehicles traversing the design experience a need to slow down given by the need to take a series of cor

In the context of transport and highways, consultation is the process by which highway authorities discuss changes with local residents and transport users.

Continuous footway

A term used to describe an uninterrupted footway that extends across a side road.


A one-way street for motor vehicles with provision for two-way cycling. Avoids forcing cyclists into detours, but can be intimidating to ride in. This is typically a low-quality solution compared to modal filters.

Controlled crossing

A form of pedestrian crossing that gives priority to pedestrians or cycles crossing a road.

Controlled Parking Zone

An area where parking is generally reserved for permit holders. These can be done many different ways, but typically the restrictions will be by time and location.

Copenhagen-style bus stop bypass

This layout is obviously found (a lot) in the Danish city of Copenhagen which is rather more cycle-friendly than London. The arrangement has a footway, then a cycle track and buses stopping next to the cycle track.


Confusingly, this can mean two things. First, it can refer to the bus arrival times display on bus shelters. 

Critical Mass

An informal, leaderless bike ride that meets on the last Friday of every month, in cities around the world. There is no route planned; the ride simply follows those who happen to be at the head of the group.


In cycle campaigning, 'culture' is used as a way of explaining why cycling levels are so much higher in countries like the Netherlands and Denmark, compared to Britain.

Cycle crossing (unsignalised)

A cycle-specific crossing of a road carrying motor traffic, at grade. This type of crossing can either give cycling priority, or give motor traffic priority. 

Cycle Design Vehicle

A term used to refer to a 'composite' of the many different types of cycle, used to provide design criteria that will accommodate all those types of cycle.

Cycle gate

A 'cycle gate' is a design used to separate the movements of cycle traffic and motor traffic at busy junctions.

Cycle lane

A cycle lane is a painted treatment for cycling on the road surface, and is defined as part of the carriageway.

Cycle path

A motor traffic-free route specifically for cycle traffic that does not run parallel to an existing highway. In other words, they are distinct routes, separate from the road network.

Cycle Route

Any infrastructure that can legally be used by cyclists, including cycle tracks, stepped cycle tracks, cycle lanes, carriageways and cycle paths.

Cycle street

A cycle street is one designed to handle large volumes of cycling, but very low volumes of motor traffic.

Cycle Superhighway

A marketing term commonly used by British local authorities to promote new cycle infrastructure, and not necessarily of good quality.

Cycle time

'Cycle time' is the length of a cycle, in traffic signal control.

Cycle track

A route specifically for bicycle traffic that runs alongside a road or street, separate from it.

Cycle Tracks Act 1984

Legislation aimed at converting public footpaths (which are paths away from roads, not footways, which run along roads) int

Cycle Traffic

Cycle Traffic is defined as 'a specific type of traffic on the network where the vehicles meet the definition of a cycle.'

Cycle training

'Cycle training' refers to any programme of instruction in cycling proficiency, be it simply learning to ride and handle a cycle, learning road rules and behaviour, or attempting to deal with more complex road environments.


A simple, catch-all term to describe a route for cycling, analogous to footway for pedestrians and roadway for motor vehicles.

Cycling Level of Service

Cycling Level of Service (or CLoS for short) is an audit tool developed by Transport for London. It is designed to assess the quality of cycling provision in existing (and proposed) schemes, with a final score out of 100. 

Cycling strategy

(Also Cycling Plan and other similar names)

A document usually prepared by a local authority setting out a strategic plan for provision of cycle infrastructure and related policies.

Cyclists Dismount

An information sign (white lettering on blue rectangle), rather than a 'no cycling' sign, meaning it does not require you to dismount unless it is already illegal to cycle (for instance on entering a pedestrian area or to use a pelican or zebra
