Item
Item Description
OBJECTID Internal feature number.

Shape Feature geometry.

YEAR_ Calendar year for which record applies.

DISTRICT FDOT District Number
1 = District 1

2 = District 2

3 = District 3

4 = District 4

5 = District 5

6 = District 6

7 = District 7

8 = Florida's Turnpike Enterprise


COSITE Combination of county and site values as a six-digit item.

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.

AADTFLG Source of AADT estimate- S=Last survey and prior year factor(s) (interim), F=Last Survey and same year factor(s) (final), C=TTMS (final)
S = Last survey and prior year factor(s) (interim)

F = Computed from Factor Category

C = TTMS

X = Cross Reference


KFLG Computation method-A=Actual Data, F=Computed from Factor Category, S=Statewide Default X=Cross Reference
A = Actual Data

F = Computed from Factor Category

S = Statewide Default

X = Cross Reference


K100FLG Computation method-A=Actual Data, F=Computed from Factor Category, S=Statewide Default X=Cross Reference for the highest 100 Hour
A = Actual Data

F = Computed from Factor Category

S = Statewide Default

X = Cross Reference


DFLG Computation method (Same as KFLG)
A = Actual Data

F = Computed from Factor Category

S = Statewide Default

X = Cross Reference


TFLG Computation method.
A = Actual Data

F = Computed from Factor Category

S = Statewide Default

X = Cross Reference


BEGIN_POST Denotes the lowest milepoint for the record.

END_POST Denotes the highest milepoint for the record.

KFCTR The proportion of AADT occuring in an hour. In this case it is the proportion that occurs in the 30th highest hour.

K100FCTR K factor for highest 100 Hour

DFCTR Total traffic in peak direction as % of two-way traffic.

TFCTR Truck & bus factor is the proportion of trucks for 24 hours

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;
Process Date: 20170701

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 JULY 2017 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: 20170505
