driving space

area above the roadway that is primarily designed for the movement of vehicles
NOTE 1 to entry: In practice, the driving space 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 2 to entry: While the…

NOTE 2 to entry: While the driving space is designed with certain vehicle characteristics in mind, local regulations typically allow a wider set of vehicles to use the driving space.

dual carriageway road segment; dual carriageway road; divided highway; dual carriageway

roadway comprised of exactly two carriageways
NOTE 1 to entry: The PIARC term is “dual carriageway road” and is recognized as a preferred term. As per the definitions provided in this document, “dual carriageway road segment” is more accurate and is the most preferred term. The term “dual carriageway” by itself is not preferred but admitted.
NOTE 2 to entry: The term “divided highway” is…

NOTE 2 to entry: The term “divided highway” is the equivalent American English term and equates to two or more carriageways.
NOTE 3 to entry: The two carriageways are typically designed for travel in opposite directions.

dynamic route

concurrent operation where transported items can only be received or delivered at stopping points within a pre-defined service corridor
EXAMPLE: Airport shuttle.
NOTE 1 to entry: The service corridor is defined by the provider, who may impose further restrictions on where stops are allowed.
NOTE 2 to entry: The service corridor often includes a communal point of interest (e.g. an…
