Results for area 6.1 Infrastructure
the infrastructure handles communications with each vehicle; installed alongside the road, the infrastructure collects data from each vehicle, provides data to the vehicle and performs any related information processing
data model package that is composed of Road Element, Intersection, Link Cost, Intersection Cost, Traffic Restriction, Special Route and Detailed Special Route
GDF level 2 feature composed of one, many or no road elements and joining two intersections, serving as the smallest independent unit of a road network at GDF level 2
part of the road network which is generally considered as a whole and which can be addressed by a single identification like a road name or road number throughout
NOTE 1 to entry In general, it is a connection within the road network, with or without crossings, which functionally can be considered as a unity. Associated carriageways shall be considered as one road.
major roads are subject to route guidance by the Interactive CDRG system
NOTE These are roads on which management personnel at the traffic control centre consider important such as national highways and other arterial roads with large amounts of traffic.
following the reception of destination and related information from the in-vehicle unit, the infrastructure provides the in-vehicle unit with information that defines the recommended route, describes route conditions, and provides an estimated travel time to the destination
local streets are all roads other than major roads
bearing of the side road section
linear section of the road network which is designed for vehicular movement having a junction at each end
NOTE 1 to entry: It serves as the smallest unit of the road network at GDF level 1 that is independent.
road signature value of the attribute quadruple (functional road class, form-of-way, road descriptor, driving direction)
part of a road, having its start and end along that road
NOTE 1 to entry: Important difference between a road section and road segment is that the segment does not necessarily end at intersections.
driving direction of the side road section
basic component of the road section entity that represents left or right side of a link and corresponds to one or more unique combinations of a navigable feature and a house number range
road segment that is bounded by two intersections and has the same attributes throughout
NOTE Generally the two intersections are different, only in some specific cases are the intersections the same, e.g. a tear-drop street or slip roads inside of complex intersections.
road section which is not part of the location to be referenced, but connected to it via an at least trivalent junction
non-negative integer which indicates if a road segment contains more than one carriageway in parallel in the direction of interest, and how many
full road number, or a significant substring of the official road name
NOTE The road descriptor is ideally three to five characters in length.
plurality of road segments lying in geographical or topological conjunction to each other
location which has a one-dimensional and continuous structure, being part of a road network
NOTE 1 to entry: It is a continuous stretch of that road network as realized in the database, which can cover different roads, and can be bounded on either side by an intersection. Alternatively it can be bounded on either side by a position on a road.
by indicating how the links and major roads ahead of the vehicle’s present position are configured, connecting network information realizes Interactive CDRG even for vehicles not equipped with onboard map databases
