-- Definition -- A linear spatial object, composed of an ordered collection of road links, which represents a continuous path in a road network without any branches. The element has a defined beginning and end and every position on the road link sequence is identifiable with one single parameter such as length. It describes an element of the road network, characterized by one or more thematic identifiers and/or properties.
-- Definition -- Specification of the state of the surface of the associated Road Element. Indicates whether a road is paved or unpaved. -- Description -- SOURCE [GDF3, Euroroads].
-- Definition -- Surface annexed to a road and devoted to offer particular services for it. -- Description -- EXAMPLES Gas station, rest area, toll area.
-- Definition -- A point spatial object that is used to either represent connectivity between two road links or to represent a significant spatial object such as a services station or roundabout.
-- Definition -- The number of lanes of a road element. -- Description -- SOURCE Adapated from [Euroroads].
-- Definition -- A collection of road link sequences and or individual road links that represents a route that is part of the international E-road network, characterized by its European route number. -- Description -- EXAMPLE E40.
-- Definition -- A classification based on the importance of the role that the road performs in the road network. -- Description -- SOURCE Adapted from [GDF, EuroRoadS].
-- Definition -- Surface which extends to the limits of a road, including vehicular areas and other parts of it. -- Description -- EAXMPLE Pedestrian areas.
-- Definition -- A linear spatial object that describes the geometry and connectivity of a road network between two points in the network. Road links can represent paths, bicycle roads, single carriageways, multiple carriageway roads and even fictitious trajectories across traffic squares.
-- Definition -- Limit for the speed of a vehicle on a road.. -- Description -- SOURCE [Euroroads].
-- Definition -- A collection of road link sequences and/or individual road links that are characterized by one or more thematic identifiers and/or properties. -- Description -- EXAMPLE Examples are roads characterized by a specific identification code, used by road management authorities or tourist routes, identified by a specific name.
-- Definition -- Description of the type of road service area and the available facilities.
-- Definition -- The width of the road, measured as an average value. -- Description -- SOURCE [Euroroads].
-- Definition -- Surface that represents the part of a road which is used for the normal traffic of vehicles.
-- Definition -- A classification based on the physical properties of the Road Link. -- Description -- SOURCE Based on [EuroRoadS].
-- Definition -- Speed limit restriction depending on the area. -- Description -- SOURCE [Euroroads].
-- Definition -- Possible service facilities available at a road service area.
-- Definition -- Values to indicate whether a road is paved or not paved.
-- Definition -- Classification based on the physical properties of the road link. -- Description -- SOURCE Based on [Euroroads].
-- Definition -- Indication to which part of a road the value of a measurement applies.
-- Definition -- Values to indicate weather conditions that affect speed limits.
-- Definition -- Possible values to indicate the nature of a speed limit.
-- Definition -- Values to indicate whether number of lanes are counted as the maximum, minimum or average number. -- Description -- SOURCE Adapted from [Euroroads].
-- Definition -- Values for the functional road classification. This classification is based on the importance of the role that the road performs in the road network. -- Description -- SOURCE Adapted from [GDF, EuroRoadS].
