GENERAL DESCRIPTION:
This dataset contains Annual Average Daily Traffic from the April 2019 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).This data represents the information collected and reported as of the most recent inventory performed and may not reflect the current conditions.

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: 20190406


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 APRIL 2019 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.
