road

curvilinear length of roadway that shares the same identification
NOTE 1 to entry: A length of the road network may be referenced by multiple designators (e.g. Main Street and Route 7). In this case, there would be two “roads” that share the same set of “carriageways”.
NOTE 2 to entry: A road can change directions at a junction.
NOTE 3 to entry: The identification is generally a name…

road cycle

vehicle meeting the legal requirements to operate in cycle lanes and cycleways
NOTE 1 to entry: In some countries, other special lanes could also be open to road cycles, such as bus lanes.

road link

link representing a contiguous length of a road between two nodes of operational or managerial significance
NOTE 1 to entry: The operational characteristics of the nodes would relate to the type of road model. For example, a traffic system can base its road links on nodes that represent junctions and road terminators.

road model

representation of a road network
NOTE 1 to entry: Road models for different systems will often define different models. For example, a public transport system can define road links based on the location of bus stops while a traffic system can define road links based on the location of junctions.

road reservation; easement

area legally reserved for road transport purposes and support
NOTE 1 to entry: Support includes physical equipment such as safety devices, signage and controller cabinets as well as access by maintenance vehicles and personnel.
NOTE 2 to entry: The road reservation includes all carriageways as well as width to allow for roadside devices, shoulders, verges, footways3.3.3), drainage…

road section

aggregation of one or more road links that represents a contiguous length of a road that shares the same management and operational strategies
EXAMPLE: A traffic signal timing plan is applied to one road section.
NOTE 1 to entry: Different road models can divide the same road into different road sections.

road segment

link that represents a contiguous length of a road link characterized by the same physical characteristics
NOTE 1 to entry: The definition of road segments is highly dependent on which characteristics are modelled by the implementation. Characteristics that can result in a new road segment include addition or subtraction of a lane, a change in roadway width, the change of road type (e.g.…

road user

mobile material entity within the road reservation
EXAMPLE: Pedestrians, road work personnel, vehicle occupants, occupied and unoccupied vehicles, horses, etc.

road vehicle

vehicle meeting the requirements to operate within the driving space of a road
NOTE 1 to entry: Unless indicated otherwise, the term typically refers to vehicles that are allowed to operate in the same driving spaces as motorized passenger cars, according to the legal requirements of the local jurisdictional entity. However, the term can be contextualized for other environments. For example,…

However, the term can be contextualized for other environments. For example, a bicycle is a “road vehicle” when the “road” is a cycleway.

roadway

part of the surface of the road reservation primarily designed for the movement of vehicles that conform to a specified set of requirements
NOTE 1 to entry: A roadway is characterized using a cross-section3.1.1) of a road facility as the roadway characteristics often change along the length of the road. See “road”, “road section”3.5.7), “road segment”, and “road link” for different types of…

NOTE 1 to entry: A roadway is characterized using a cross-section3.1.1) of a road facility as the roadway characteristics often change along the length of the road. See “road”, “road section”3.5.7), “road segment”, and “road link” for different types of stretches of roadway.
NOTE 2 to entry: In practice, the roadway design considers a variety of issues, which can result in suboptimal road segments that violate normal design guidelines. Such locations are typically posted with warning signs, but they are still designed for the movement of vehicles.
NOTE 3 to entry: While the roadway is designed with certain vehicle characteristics in mind, local regulations typically allow a wider set of vehicles to use the roadway.
Note 4 to entry: The roadway includes any contiguous hard shoulders, hardstanding3.1.17) and reserved lanes3.1.14).
