Traffic Analysis Zones (TAZ) for the COG/TPB Modeled Region from Metropolitan Washington Council of Governments. The TAZ dataset is used to join several types of zone-based transportation modeling data. For more information, visit https://plandc.dc.gov/page/traffic-analysis-zone.

Transportation Analysis Zones (TAZs) are used in the Metropolitan Transportation Commission travel and Urban Sim models for the San Francisco Bay Region. These models are used in processes to forecast population growth, economic growth, and transportation/transit capacity and responsiveness and then distribute those results throughout the region.Data tables containing modeling results are joined to the TAZ features using a zone id (taz1454). Tables currently available for download are as follows:Plan Bay Area 2040 ForecastEmployment (total employment, TAZ resident employment, retail employment, financial and professional services employment, health, educational, and recreational employment, manufacturing, wholesale, and transportation employment, agricultural and natural resources employment, and other employment)Households (number of households and household income quartile)Land Use and Transportation (area type, commercial or industrial acres, residential acres, number of single-family and multi-family dwelling units, time to get from automobile storage location to origin/destination, and hourly parking rates)Population and Demographics (total population, household and group quarter populations, population by age group, share of population that is 62+, high school enrollment, and college enrollment)

These are the Traffic Analysis Zones (TAZ) used in the Statewide Travel Model. This dataset contains only basic geographic information about the zones.TAZ boundaries are defined based on Census geographies (block, block group and tract). Care has been taken so that TAZ nest within Census tracts wherever possible in order for more direct matching with Census data. TAZ boundaries are also defined by major transportation facilities (such as roadways or rail lines), major environmental features (such as rivers), and with underlying land uses. The relative size of the TAZ was also a factor in deciding new TAZ boundaries if the zone size was large and the zone was thought to have a significant amount of socioeconomic activity. The size of TAZ varies from under 10 acres in the downtown to more than 100,000 acres in the mountain or lake zones. The average zone size is approximately 350 acres, which is a little over ½ square mile. Generally, TAZ in urban areas are smaller than in suburban and rural areas.There are currently 5 travel model spaces in Utah: Cache MPO (2), Dixie MPO (3), Summit (4), UDOT rural areas (0), and the combined WFRC/MAG MPO (1) model space. The model space indicators shown in parentheses above are coded in the Subarea_ID field. As travel demand model software requires that each TAZ be uniquely identified starting with the number 1, each model space has assigned its own unique TAZ identifier numbering sequence which is coded into the SubAreaTAZID field. However, this rule also applies to the statewide travel model, which is an aggregation of all the TAZs from the five model spaces into a single layer. In this statewide layer, the TAZID field is the unique identifier for the Utah Statewide Travel Model (USTM). CO_TAZID is the field used to link each TAZ to its socioeconomic data. It is a combination of the County FIPS number and a TAZ identifier within the county or from within an MPO model space.

A printable map of Traffic Analysis Zones for the Lincoln Metropolitan Planning Organization. A traffic analysis zone is the unit of geography most commonly used in conventional transportation planning models. The size of a zone varies, but for a typical metropolitan area, a zone of under 3000 people is common. The spatial extent of zones typically varies in models, ranging from very large areas in the suburb to as small as city blocks or buildings in central business districts. Zones are constructed by census block information. Typically these blocks are used in transportation models by providing socio-economic data. States differ in the socio-economic data that they attribute to the zones. Most often the critical information is the number of automobiles per household, household income, and employment within these zones. This information helps to further the understanding of trips that are produced and attracted within the zone. These zones can change or altered to eliminate unneeded areas to limit the "computational burden."

TRAFFIC_ZONES_TIGER00_IN contains traffic analysis zones in Indiana identified by the US Bureau of the Census. Vigo, Madison, and Monroe counties were not available at time of creation. Data is from U.S. Department of Commerce, U.S. Census Bureau, Census 2000 Tiger Line Files.

The 2006 Second Edition TIGER/Line files are an extract of selected geographic and cartographic information from the Census TIGER database. The geographic coverage for a single TIGER/Line file is a county or statistical equivalent entity, with the coverage area based on the latest available governmental unit boundaries. The Census TIGER database represents a seamless national file with no overlaps or gaps between parts. However, each county-based TIGER/Line file is designed to stand alone as an independent data set or the files can be combined to cover the whole Nation. The 2006 Second Edition TIGER/Line files consist of line segments representing physical features and governmental and statistical boundaries. This shapefile represents the current Traffic Analysis Zones for Dona Ana County stored in the 2006 TIGER Second Edition dataset.

This file shows the most current Metropolitan Council Transportation Analysis Zone (TAZ) 2020-2040 forecasts for cities and townships within the 7-County Metropolitan Area. The TAZ system in this shapefile is the most recent, official TAZ system (with 3,030 zones).

This shapefile title has been renamed; the previous name was Transportation Analysis Zones (TAZ) 2010 with Current Forecasts

Note: Forecasts for the older TAZ system with 1,566 zones are available in theTransportation Analysis Zones (Legacy TAZ System w/1,566 Zones) with Current Forecasts shapefile.

IMPORTANT NOTES:

These TAZ forecasts will change multiple times over the next few years.

The Metropolitan Council will ask cities and townships to allocate their TAZ forecasts as part of their 2018 Comprehensive Plan Update (go to http://www.metrocouncil.org/Handbook/Plan-Elements/Transportation.aspx
for more information about this process). Communities may also revise their current TAZ forecasts before the 2018 Comprehensive Plan Update. In the meantime, the Council provides these Current TAZ forecasts for transportation planning.

If you are using TAZ forecasts for analysis and/or transportation planning, please download the latest version of this shapefile to ensure you are using the most up-to-date data.

If you represent a community that wants to revise your TAZ forecasts, please contact your community's sector representative or Dennis Farmer (see contact information at the end of this document).

A TAZ usually consists of one or more census blocks, block groups, or census tracts. These geographic units were generated for 2020 by BMC staff in consultation with member jurisdictions. The Census Bureau discontinued TAZs as an official geography prior to the 2020 Census. This is the official GIS dataset that will be used for modeling travel demand at BMC. This TAZ dataset includes the BMC region jurisdictions only. Traffic analysis zones (TAZs) are basic spatial units of analysis facilitating the ability of transportation planners to forecast changes in commuting patterns, trip volumes, and modes of travel, and to develop plans to meet the changing demands for transportation facilities and capacities. Each TAZ represents an area containing similar kinds of land use and commuter travel.FIELDSSTATEFP20 - State (FIPS)COUNTYFP20 - County (FIPS)NAME - TAZ NameTAZ20 - TAZ NumberJUR - Jurisdiction Number (BMC internal)JURNAME - Jurisdiction NameRPD20 - RPD NumberRPDNAME - RPD NameACRES - Land area in acresDate: 02/24/2022Update: None planned, 2030 boundaries will be added separatelySource: Baltimore Metropolitan Council
