GENERAL DESCRIPTION:
This dataset contains Annual Average Daily Traffic from the January 2018 version of the Florida Department of Transportation Roads Characteristics inventory (RCI) dataset. The Annual Average Daily Traffic feature class feature class shows the location of traffic breaks and affiliated annual average daily traffic volumes in the state of Florida as derived from event mapping selected traffic characteristics from the FDOT Traffic Characteristics Inventory (TCI).

ROADWAY A unique 8-character identification number assigned to a roadway or section of a roadway either On or Off the State Highway System for which information is maintained in the Department's Roadway Characteristics Inventory (RCI).

DESC_FRM The name of the intersecting road at the beginning of the roadway segment. (There are instances that the intersection is at a county boundary, a facility crossing, a bridge, etc.)

DESC_TO The name of the intersecting road at the end of the roadway segment. (There are instances that the intersection is at a county boundary, a facility crossing, a bridge, etc.)

AADT The total volume of traffic on a highway segment for one year, divided by the number of days in the year.

USER NOTES:
All data for this dataset are logically consistent.
This dataset is complete as of date of production.
GeoPlan relied on the integrity of the attribute information within
the original data.

The FDOT Annual Average Daily Traffic feature class provides spatial information 
on Annual Average Daily Traffic section breaks for the state of Florida.  In addition, 
it provides affilated traffic information like KFCTR, DFCTR and TFCTR among 
others.

who are data stewards, producers, or publishers. The data available in
FGDL may not be the most current version of the data offered by the
data source. University of Florida GeoPlan Center makes no guarantees

A note about data scale: 

Scale is an important factor in data usage.  Certain scale datasets
are not suitable for some project, analysis, or modeling purposes.
Please be sure you are using the best available data. 

1:24000 scale datasets are recommended for projects that are at the
county level.
1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.
1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.
1:125000 scale datasets are recommended for projects that are at the
regional or state level or larger.

Vector datasets with no defined scale or accuracy should be
considered suspect. Make sure you are familiar with your data
before using it for projects or analysis. Every effort has been
made to supply the user with data documentation. For additional
information, see the References section and the Data Source Contact
section of this documentation. For more information regarding
scale and accuracy, see our webpage at:

DATA LINEAGE SUMMARY:
This dataset was created using ESRI event mapping. The route system is the 
Transportation Data and Analytics' linear referencing system (LRS). The event 
source data are from an Oracle view of the secbrks table. The query used to 
generate the source table is: select 
"YEAR","DISTRICT","COSITE","ROADWAY","BEGIN_POST","END_POST","A
ADT","AADTFLG","KFCTR","KFLG","K100FCTR","K100FLG","DFCTR","DFLG",
"TFCTR","TFLG" from secbrks where year = 2006

The data set was taken from the Florida Department of Transportation Statistics Office from the following webpage: http://www.dot.state.fl.us/planning/statistics/gis The data set was originally downloaded in JANUARY 2018 as the RCI basemap. Specific instructions, created by URS Corporation and the GeoPlan Center, were carried out. The data set is then to be updated on a regular basis. The data was originally in UTM Zone 17, Nad83, units meters. The data was projected to Albers HPGN. -Download the most recent Statewide Personal GeoDataBase -Export from feature class "aadt" to shapefile -Project the shape file to the standard FGDL projection. -Deleted items Shape_Leng, Shape_Length -Add Descript item based on AADT Process Date: 20180111
