NameTypeDescription
Crossfall P_SINGLEVALUE / IfcRatioMeasure Specifies the nominal crossfall as a ratio measure (slope) at the location of the event.
DesignSpeed P_SINGLEVALUE / IfcLinearVelocityMeasure Speed selected in designing a new road or in modernizing, strengthening or rehabilitating an existing road section, to determine the various geometric design features of the carriageway that allow a car to travel safely at that speed, under normal road surface and weather conditions.
NOTE  Definition according to PIARC. NOTE  The design speed is not constant, but may vary depending on the conditions of relief (plain, hill, mountain).
DesignTrafficVolume P_SINGLEVALUE / IfcCountMeasure The traffic volume used for planning and design purposes specified as the number of vehicles per day . Typically given as AADT - Average Annual Daily Traffic
DesignVehicleClass P_SINGLEVALUE / IfcLabel A vehicle designator with content according to local standards.
LaneWidth P_SINGLEVALUE / IfcPositiveLengthMeasure Standard nominal width of one trough lane.
NumberOfThroughLanes P_SINGLEVALUE / IfcCountMeasure The total number of through lanes on the segment. This excludes auxiliary lanes, parking and turning lanes, acceleration/deceleration lanes, toll collection lanes, shoulders etc.
RoadDesignClass P_SINGLEVALUE / IfcLabel A road design class designator with content according to local standards.
