Traffic Analysis Zones (TAZ) - Oahu
Listed in Hawaii Open Data
[ Metadata ] Traffic Analysis Zones for the Island of Oahu, 2022.
Description
Source: Oahu Metropolitan Planning Organization (OMPO), Feb. 2024. A traffic analysis zone (TAZ) is a geographic unit used in transportation planning models.
TAZs are used to represent the spatial distribution of trip origins and destinations. TAZ boundaries are defined based on Census geographies (block, block group and tract). Care has been taken so that TAZs 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), major environmental features (such as rivers), and with underlying land uses. The relative size of the TAZ was also a factor in determining new TAZ boundaries if the zone size was large and the zone was thought to have a significant amount of socioeconomic activity. Generally, TAZs in urban areas are smaller than those in suburban and rural areas.
