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 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

Traffic analysis zones (TAZs) are special-purpose geographic entities delineated by state and local transportation officials for tabulating traffic related data from the decennial census, especially journey-to-work and place-of-work statistics. A TAZ usually consists of one or more census blocks, block groups, or census tracts. For Census 2000 TAZs are defined within county. Each TAZ is identified by a 6-character alphanumeric census code that is unique within county or statistically equivalent entity. A code of ZZZZZZ indicates a portion of a county where no TAZs were defined. The U.S. Census Bureau first provided data for TAZs in the 1980 census, when it identified them as 'traffic zones.' For the 1990 census, the TAZs were defined within Census Transportation Planning Package (CTPP) areas. TAZs were not shown in any 1990 Census TIGER extracts. The U.S. Census Bureau subsequently inserted the TAZs into the Census TIGER database and began extracting them starting with the 1994 TIGER/Line files. The Census 2000 TAZ program was conducted on behalf of the Federal Highway Administration, Department of Transportation, which offered participation to the Metropolitan Planning Organizations (MPOs) and the Departments of Transportation (DOTs) in the 50 states and the District of Columbia. The following states did not have a participating MPO or State DOT for the Census 2000 TAZ Program: Delaware, Hawaii, Montana.

Developed by the Census with the assistance of BMC. These are the official Census Traffic Analysis Zones (TAZ) 2000. A traffic analysis zone (TAZ) is a special area delineated by state and/or local transportation officials for tabulating traffic-related data- especially journey-to-work and place-of-work statistics. A TAZ usually consists of one or more census blocks, block groups, or census tracts.Date: 6/1/2000Update: none planned, 2010 boundaries added separatelySource: Census/BMC.

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."

A TAZ analysis is conducted every 5 years as part of the Capital Regional Transportation Planning Agency’s (CRTPA) Regional Mobility Plan. This TAZ analysis is part of CRTPA's Connections 2045 Regional Mobility Plan which can be found here Link.Traffic Analysis Zone: A traffic analysis zone (TAZ) is a special area delineated by state and/or local transportation officials for tabulating traffic-related data–especially journey-to-work and place-of-work statistics. A TAZ usually consists of one or more census blocks, block groups, or census tracts.

These are the Traffic Analysis Zones (TAZ) used in the Wasatch Front Travel Model. This dataset contains only basic geographic information about the zones.The Wasatch Front travel model region covers the urbanized portion of Weber, Davis, Salt Lake and Utah Counties and the portion of the Box Elder County from Brigham City South (Salt Lake City-West Valley City, Ogden-Layton, and Provo-Orem Urbanized Areas). The region is divided into 2,881 Traffic Analysis Zones (TAZ). 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.

This dataset is intended for researchers, students, and policy makers for reference and mapping purposes, and may be used for basic applications such as viewing, querying, and map output production, or to provide a basemap to support graphical overlays and analysis with other spatial data.
