California Metropolitan Transportation Commission Traffic Analysis Zones, 2002
Abstract/Contents
- Abstract
- This polygon shapefile contains traffic analysis zones with population statistics for the San Francisco Bay Area in California. These data have ben clipped to the shoreline for cartographic representation. The California Metropolitan Transportation Commission (MTC) maintains a set of regional travel analysis zones for use in MTC planning studies. These travel analysis zones (TAZs) are typically small area neighborhoods or communities that serve as the smallest geographic basis for travel demand model forecasting systems. From time to time, MTC updates the regional travel analysis zone system to reflect changes in decennial census geography, changes in computing capability, and forecasting needs for particular corridor studies. The original MTC zone system, with 290 zones, was created in 1965 by planners of the MTC predecessor agency, the Bay Area Transportation Study Commission. MTC has since updated the zone system several times over the past decades, increasing to 440 zones in the mid-1970s, to 550 zones in the early 1980s, to 651 zones in 1987, to 700 zones in 1989, to 1,099 zones in 1993, and to 1,454 zones in 2002. This layer is part of the Bay Area Metropolitan Transportation Commission (MTC) GIS Maps and Data collection.
- Purpose
- 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.
