MDOTnameROUTE_IDROUTE_IDString700Non zero padded identifier for a route in a county. Can be followed by an X (Crossover) or a C (Channel). If followed by an A, E, or W this is to signify Alternate, East or West. If the route is a State Route, US Route, or Interstate Route the route id is representative of its signing and designation. (i.e. MS 25 is 25 in each county it passes through so long as the route class is MS as well). Route IDs are only unique to one county unless combined with a route class in the case of a State Route, US Route, or Interstate Route. A route id can also be unique when paired with a county and a pass_dir.MDOTIDPASS_DIRPASS_DIRString100Denotes the specific direction of a route, P (primary) or S (secondary). Previous systems that were single centerline would have only had a primary direction. The secondary direction is the roadway running in the opposing direction to the primary roadway (Divided Highway) for a single route.MDOTdirectionSEG_NOSEG_NOSmallInteger110Denotes the specific segment of a route in a county. Segmentation can occur due to routes overlapping one another as well as offsets at intersections.MDOTnumberINV_NOINV_NOString700Zero padded version of the ROUTE_ID field. Used to reference legacy data that utilized fixed width fields.MDOTnumbersID1ID1Integer880Primary ID field. Should not be used for long term referencing since this can change with each publication.MDOTidWM_VALIDFRWM_VALIDFRDate800Date that a segment went live (Valid From). With our current data model, most roads will have the 20th of March 2013. If a segment has had a change since this date, the validfrom time will have changed to reflect this change.MDOTDateWM_VALIDTIWM_VALIDTIDate800In the event that a end of life date were known for a route and the new alignment had been established at a future date this field would show the end of serviceable life date for any segment involved.
