This dataset contains 1997 traffic data for the state of Florida from all portable and telemetered traffic meters.
The purpose of these data is to provide Florida Department of Transportation transportation statistic meter locations and highway traffic flow information for the purposes of planning and research.
Converted from original ESRI Shapefile format to ESRI Coverage format. Appended separate coverages to form a single dataset containing both Telemetered and Portable sites differentiated by the SITETYPE Item.
THE DATA INCLUDED IN THIS APPLICATION ARE BASED ON INTERPRETATION OF AVAILABLE INFORMATION AND SHOULD NOT BE CONSTRUED AS LEGALLY BINDING. Scale is an important factor in data usage. Certain scale data sets are not suitable for some projects, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale data sets 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 data sets are recommended for projects that are at the multi-county or regional level. 1:250000 scale data sets are recommended for projects that are at the regional or state level or larger.
Relied on the integrity of the attribute information within the original data layer. However, during the QA process a new item, DESCRIPT was added. It is based on CW_DIST attribute information. Likewise, USACE_CIVIL was renamed from the original coverage to CW_DIST set to REQUIRED.
Certain node/geometry and topology (GT)-polygon/chain relationships are collected or generated to satisfy topological requirements. Some of these requirements include: chains must begin and end at nodes, chains must connect to each other at nodes, chains do not extend through nodes, left and right GT-polygons are defined for each chain element and are consistent throughout the transfer, and the chains representing the limits of the file (neatline) are free of gaps. The neatline is generated by connecting the four corners of the digital file, as established during initialization of the digital file. All data outside the enclosed region are ignored and all data crossing these geographically straight lines are clipped at the neatline. (Exception: During the QA/QC process all data is examined and if errors are found and corrections are possible, then data is corrected accordingly. This process is documented in the Process_Step.) Data within a specified tolerance of the neatline are snapped to the neatline. Neatline straightening aligns the digitized edges of the digital data with the generated neatline, that is, with the longitude/latitude lines in geographic coordinates. All internal polygons are tested for closure. Certain attributes and/or entities, e.g. closure line, convey data quality information. When information to be encoded in the subfield is known to be not applicable (undefined, not relevant), then the subfield is valued by a string of 9s; and when the information to be encoded is relevant but unknown (or missing), then the subfield is valued by a string of 9s.

Vector data representing the average daily traffic statistics.
The process step describes, in general, the process used in the production of data sets. The originating agencies created the original spatial coverage. GeoPlan, during the QA/QC process included the following aspects: (1) Reprojected data to FGDL Albers (2) Set Precision to DOUBLE (3) Set Tolerances to FGDL Standards
FDOT County site number
Unknown
FDOT road section number on which road telemeter is located
Unknown
Milepost number of road section
Unknown
(Annual average daily traffic) = the total volume of traffic on highway segment for one year divided by the total number of days in a year.
Unknown
(Design hour traffic) = proportion of aadt occurring in an hour.
Unknown
(Directional distribution factor) = the percent of the total two-way hourly traffic that occurs in the peak direction.
Unknown
(Truck factor) = the percent of truck traffic for a 24 hour period.
