Key Attributes These attributes are unique to this feature class, or are Core Attributes used differently than other feature classes extracted as part of the SWAAI project.
SideOfRoad This feature class uses the SideOfRoad field in a particular way. The leftmost stripe section, or sections in the case of paired stripes, is designated L=Left, and the rightmost stripe (or stripes) is designated R=Right. Leftmost and rightmost were based on the travel direction of the nearest lane. Any stripes between the leftmost and rightmost were designated as C=Center stripes.
StripeWidth_in The width of the stripe section, in inches, rounded to the nearest whole inch. These widths are typically 4”, 6”, 8”, or 12”.
StripeColor The paint color of the stripe section, including the StripeColor domain: White (1) or Yellow (2).
StripePattern The striping pattern of the stripe section, including the StripePattern domain: Solid (1), Dashed (2), Dotted (3), or Lane Drop (4).

From_Z/ToZ Elevation (Z) values were excluded as data fields since this dataset represents a statistical quantification of features in its vicinity, rather than the physical locations of any of those features in particular.
