Nicole, That would be great, I guess we didnt have a chance to talk about this. I did discuss some of those questions between making that presentation and presenting and gave the following answers for the other states:
I found out:
WV does extensively utilize lookup tables and maintains 1:1 coordination between domains and lookup tables in their practice.
Arizona migrated to Roads and Highways from a LRS that was referent based, and as such they do heavily utilize referents and are constantly pushing for more development and support of referent based methods for geo-locating and reporting.
I eventually figured out OTT means "open to traffic" and I think having that date attribute on geometric events like lanes is a wonderful idea. I mentioned in the presentation they also have some date attributes for HPMS submittal items from traffic count and pavement management systems, which is also a good idea since those separate systems need to be integrated into a HPMS submittal while representing counts or pavement collected and processed on a network as-of a not current network, sometimes that collection and processing is representative of a highway network that is a year old or more by the time it is integrated into HPMS.
Arizona also keeps a paint attribute and domain in certain paint-relevant events like auxillary lanes, bicycle lanes, channelizations, and medians, and I think I heard James mention they have a pretty precise paint striping GIS polyline layer which I think is awesome and supporting evidence that Arizona DOT is really going great things.
