The roadway definition is used for influence surface-based live load analysis. Based on the roadway definition, an influence surface path is generated and influence coefficients are computed. OpenBrIM Influence surface-based live load analysis automatically places lanes at the transverse locations, so the only important parameter to define is the extent of the roadway.
General
Bridge: Understanding the bridge data is crucial to identify the deck components where the roadway will be placed.

Station[ft]: Station along the PGL
Transverse Offset[ft]: The transverse offset is measured from the PGL, where the PGL is defined as 0.
Right Width[ft]: The distance that goes towards the right side when looking up the station along the alignment line.
Left Width[ft]:The distance that goes towards the left side when looking up the station along the alignment line.
Skew[deg]: A skew angle of 0 degrees indicates that the line is perpendicular to the PGL. A positive skew angle rotates the perpendicular line in a clockwise direction, while a negative skew angle rotates it in a counterclockwise direction.
