Abstract:
             This is a geo-dataset delineating the Highway System of the State of Missouri.  It was extracted from the original MoDOT roadway coverage.
The MoDOT roadway coverage is based on a Dynamic Segmentation model. Dynamic Segmentation models linear features using routes and events, associating multiple sets of attributes to any portion of a linear feature. The ARC feature class forms the basic linear infrastructure from which Dynamic Segmentation models or route-systems are built. NODES indicate the endpoints and intersections of ARCS. The 'from-node' is the first vertex of the arc; the 'to-node' is the last vertex. Together, they define the direction of the arc. Arc-node topology defines connectivity of Dynamic Segmentation models or route-systems. Route systems are built without modifying the underlying arc-node topology. A route represents a single linear feature, such as a city street or highway. Routes are linear features composed of one or more arcs or parts of an arc; for example, a highway may be composed of a number of connected arcs. A route, for Dynamic Segmentation purposes, is simply a linear feature with measure values attached to it. Each route is associated with a measurement system, a linear method consisting of a starting value and other measures along the route, which describe distance along them. The measures are used to locate data that describe parts of the route. Data along routes is modeled using events. Event data, such as accidents, signs, functional classification, pavement condition, pavement type, is based on the Dynamic Segmentation model, the foundation of which is the route system.

The state system network (IS, US, MO, RT) originated from 1980-DIME data, which was later updated with 1995 TIGER files from the US Census Bureau. Currently the coverage is updated monthly utilizing design plans, GPS, DOQQ and county and city maps.

Purpose:

Generally used for coarse geographic and environmental analysis. The Dynamic Segmentation model is used to reference specific data or events (accidents, pavement type, speed limit, signage, etc...) to locations along a route or travelway, allowing more specific analysis or modeling.

Overview_Description:
Entity_and_Attribute_Overview:
The ARC feature class forms the basic linear infrastructure from which Dynamic Segmentation models or route-systems are built. NODES indicate the endpoints and intersections of ARCS. The 'from-node' is the first vertex of the arc; the 'to-node' is the last vertex. Together, they define the direction of the arc. Arc-node topology defines connectivity of Dynamic Segmentation models or route-systems. Route systems are built without modifying the underlying arc-node topology. The routes and sections of a route-system are stored in two INFO data files. These tables are the route attribute table (RAT), which defines a route feature class and the section table (SEC), which defines a section feature class. Together, these feature classes define a route-system.

The '.aat' (Arc Attribute Table) stores descriptive data about the ARCS. There is one record in the '.aat' for each ARC in the coverage. The record is related to the feature by the internal sequence number stored for each ARC.

The '.nat' (Node Attribute Table) stores descriptive data about the NODES. There is one record in the '.nat' for each NODE in the coverage. The record is related to the NODE by the node's internal sequence.

The 'Route.Tway' feature class is a Dynamic Segmentation model or route system built using the continuous log-mile system. The '.rattway' (ROUTE ATTRIBUTE TABLE.TWAY) stores descriptive data about the ROUTES of the continuous log-mile system. There is one record in the '.rattway' for each ROUTE in the feature class. The record is related to the feature by the internal sequence number stored for each ROUTE.
