- Transportation Analysis Zones (ZIP, 263KB)
- This dataset represents the 665 TAZs within Clark County that serve as the primary geographic unit of analysis in RTC’s regional travel demand forecasting model. They are used to spatially aggregate socioeconomic data related to land use and used as travel model inputs. TAZs also serve as the origins and destinations for travel in the region modeling framework. (Also available as KML.)
The Taskar Center for Accessible Technology: OS-CONNECT Viewer
“Under the directive of the state legislature and using innovative technology by the Taskar Center for Accessible Technology, Washington is now creating an AI-generated, human-vetted network graph inventory of sidewalks across Washington State—the OS-CONNECT dataset. With this data, state agencies, local governments, and community organizations will have the information they need to address critical accessibility, safety, and equity gaps within the transportation network. Led by TCAT, with the help of industry partner Gaussian Solutions LLC, this effort is not just a significant step in urban planning but a stride towards inclusivity and better quality of life.” (source: https://tcat.cs.washington.edu/washington-state-proviso/)
