Used By: This entry is used directly by one other data structure in this standard, a DF called DF_ITIS-
Codes_And_Text <ASN> <XML>. In addition, this item may be used by data structures in other ITS
standards.
6.18 Data Element: DE_Lane / Roadway Descriptions
Use: The ITIS enumeration list commonly referred to as "Lane / Roadway Descriptions," is assigned the
upper byte value of [32] (which provides for value ranges from 8192 to 8447, inclusive). This list is
formally called "LaneRoadway" in the ASN.1 and XML productions. The items in this enumeration list are
not allowed to be used as an event category classification. This list contains a total of 61 different phrases,
divided into 6 further sub-categories (the division into these sub-categories is informational only and other
groupings may also be used). The remaining 66 values up to the lower byte value of [127] are reserved for
additional "national" phrases in this byte range. Local phrases may be added to the list starting with the
lower byte value of 128 and proceeding upward from there (in other words, the first value assigned for any
local additions to this list would be given the value 8320).
