Abstract:
This dataset contains 2000 Traffic Analysis Zones (TAZ) as they are defined by the Bureau of the Census. The data contains selected fields from the Summary 1 file that includes,information on total population, race, sex, age, and household.m,A TAZ is a statistical entity delineated by state and/or local transportation officials for tabulating traffic-related census data.
Purpose:
This dataset was created to provide a digital represention to be used for analytical and planning purposes.

Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Explanation:
Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modelling 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: <http://geoplan.ufl.edu/education.html>. These data are based on interpretation of available information and should not be construed as legally binding.

A traffic analysis zone (TAZ) is a statistical entity delineated by state and/or local transportation officials for tabulating traffic-related census dataŸespecially journey-to-work and place- of-work statistics. A TAZ usually consists of one or more census blocks, block groups, or census tracts. For the 1990 census, TAZs were defined as part of the Census Transportation Planning Package (CTPP). The U.S. Census Bureau first provided data for TAZs in conjunction with the 1980 census, when it identified them as þþtraffic zones.üü Each TAZ is identified by a six- character alphanumeric code that is unique within county or statistically equivalent entity. For the 1990 census, TAZ codes were unique within CTPP area, which generally conformed to a metropolitan area.

Process_Description:
Data was originally released by US Census Bureau in 2000. Data was downloaded by GeoPlan in shapefile format from ESRI (<http://www.esri.com/data/d ownload/census2000_tigerline/index.html>). When received, data was in Geographic projection, Datum: NAD83, Spheroid: GRS1980, Units: Decimal degrees. The data was then projected to FGDL Albers HPGN (See "Map Projection Parameters" below).
