1. To read or retrieve data.
2. The ability to drive onto or across a roadway.
Related to a name, number, system, or other non-physical classification.
A Characteristic milepoint used as a semi-permanent point on a roadway. If the
Characteristic is eligible as an Anchor, this milepoint (location) may be used to
tie other feature locations to it. If the Anchor's milepoint shifts, the associated (or
tied) feature moves with it -- keeping the same distance between them.
Personnel who have a FDOT issued RACF User Identification account and
password to be authenticated within the Department's information systems.
Florida's official electronic map of major highways, maintained by the
Transportation Statistics Office. The Base Map contains all On-System roads
and the major Off-System public roads. Using Roadway ID, the Base Map is
linked to RCI--but neither updates the other. Distance calculations are
determined from road lengths in the Base Map.
To manipulate numeric data according to some formula. Unless specified, result
is not maintained/tracked.
A virtual line parallel to a roadway, usually at or near the center of the traveled
lanes.
1. A property of a feature (e.g. the Characteristic Service Plaza Name for the
Feature Service Plaza).
2. An object in a feature collection (e.g. the Characteristic Number of 12 Ft. Stop
bars for the Feature Stop bars) for which roadway information is stored.
Under the jurisdiction of… (see Jurisdiction). Usually implies ownership.
One of the 67 administrative subdivisions of the State of Florida. The County
number is part of the numeric identifier for a roadway section (digits 1 and 2 of
the Roadway ID).
A map showing the Roadway IDs for roadways on the State Highway System
within a county.
The date that the data value stored in the database changes. This date is
input/set by the system (same as/see Date Stamp). This date will be satisfied by
the Last Update Date recorded.
Assumption of responsibility for the accuracy of features and characteristics,
including providing documentation, training, and quality assurance for the
collection and entry of the data.
The computer generated date/time that records when the data was saved in the
data system (when the user hits the update button). This date is input/set by the
system.
A length between two points. In RCI, distances are usually measured along the
centerline of a curving roadway, not on a straight line cutting across the curve.
A measuring device (electronic or mechanical) used to determine lengths of
roadway sections and longitudinal locations of existing characteristics along the
roadway.
Organizational subdivision of the state for FDOT use. RCI uses two forms of
District, Managing District and Geographical District.
Any road that has a median.
An instance of an object that is inventoried along a roadway. It may be an actual
physical object, such as a cross drain, or it may be a virtual entity that groups
items that are inventoried as a collection, such as the HPMS (Highway
Performance Monitoring System) statistical sample. A Feature stores
information concerning the location of the object. Information concerning the
object itself is stored as one or more Characteristics.

There are four types of features: 1) Operational, 2) Maintenance, 3)
Administrative, and 4) Physical.
The process by which roads are grouped according to the character of service
they are intended to provide. Arterial roads provide long-distance mobility but
little direct access. Local roads provide access but not mobility. Collectors are
intermediate in these properties.
A discontinuity in a route. The discontinuity may be caused by a geographical
object or by an administrative decision not to define a roadway segment as part
of the route. For example, a gap could be a roadway segment that travels into
another state (such as Georgia) and then returns. The only information recorded
in RCI about the gap is that it exists and at what sequence in the route it is
located.
The overall direction of a Roadway Section, using the eight points of a
compass, e.g. North, Northeast, East, Southeast, South, etc. This direction is
determined by the overall direction in which the Roadway Section milepoints
ascend. The general compass direction is not necessarily the same as the
overall roadway direction. For example, I-4 is considered a West to East route
although the compass direction for a number of its Roadway Sections are coded
as South to North.

and many other geographical features in a county, and which may be used as
the background for the County Section Number Key Sheet.

background.
The difference between the ending milepoint and the beginning milepoint of the
roadway section, without regard to the Status. Also known as Section Length.
A report to the Federal Highway Administration using General Interest Roadway
Data and other data to describe public road conditions and performance.
A randomly selected roadway segment on or off the State Highway System for
which detailed data are collected for the HPMS report. HPMS Sample data are
stored primarily in Feature 118 of RCI.
A map with HPMS samples indicated on roadways.
All roads that are functionally classified as Rural Major Collector or above; or
are part of the National Highway System.
To recognize and/or record particular properties of an object that make it
different from other objects of the same type.
A Feature with Characteristics that RCI always keeps at a mutually consistent
location, if the beginning milepoints and ending milepoints for the
Characteristics are the same. This allows the user to change the milepoints for
just one of them and the computer automatically changes the others.
Involving more than one mode of travel, such as an airport--which connects the
highway and air modes.
The date a person observed a change in the value of a characteristic.

ownership. For RCI purposes, jurisdiction may be State, County or City.
The most recent date that the data value stored in the database changed; this
date is input/set by the system.
A feature with characteristics that can be represented by a line, rather than by
points or areas. A length feature may be defined for all or part of a section of
roadway.
A one-dimensional characteristic, which can be represented by a line or set of
lines. In RCI, these are along the length of a roadway.
A geographic entity that can be represented by a line or set of lines. For
example, roads, rivers, and telephone lines are linear features.
A mechanism for finding and stating the location of a point along a linear
network by referencing it to a known point.

1. To have jurisdiction over a road (see Jurisdiction).
2. To keep a road in good condition.
Related to the upkeep and repair of a roadway.
One of eight entities that manages State roads. Districts 1-7 manage nonTurnpike roads in their respective geographical areas. The Turnpike Enterprise
may manage roads in any of the other District's geographical areas.
A barrier or other physical separation between two lanes of traffic traveling in
opposite directions.
A physical sign located along a roadway, indicating the number of miles (usually
rounded off to the nearest mile) from a defined point. For example, the small
green mile markers along each Interstate highway in Florida show the number
of miles from the west or south end of the portion of that highway in Florida.
Any point on a roadway section (see definition) that is identified or referenced
by its distance in miles from the beginning of the roadway section. Milepoints
increase in the direction of inventory and are used to designate or record the
position or location of features along a roadway section. The milepoint in the
RCI database is recorded as a number with 3 significant decimal places (to the
thousandth of a mile), e.g. mp 4.123 or 4.123 mi.
1. See Milepoint.
2.An obsolete term formerly used interchangeably sometimes with milemarker
and sometimes with milepoint.
A Federal System designation assigned to specific roadways.
The sum of all the segments on a roadway section that are drivable and that do
not have their data carried under a different Roadway ID. This excludes portions
that are shown in Feature 140 to be inactive, deleted, or pending, or that have
an exception coded in Feature 141.
Calculation Formula of Net Section Length = Gross Section Length minus (any
portion included in Feature 141) minus (any portion with Feature 140's
STATEXPT = PENDING, 01; INACTIVE, 04; DELETED, 05; or GIS ROUTES,
06).
A virtual point, usually located at a physical object with a semi-permanent
location, that is easy to locate and identify. In the Crash Analysis Reporting
(CAR) system, each Nodes is assigned a number.
Lateral distance of an object from a road centerline or other line parallel to the
centerline.
