Resource Abstract:
- description: 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, aerial
imagery and county/city maps. All Census related fields have been removed, as they are not utilized nor updated by MoDOT.
As of July 2007, approximately 87% of the state system network was matched to either imagery, gps or other improved data source.
