Transportation Analysis Zones

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 Forecast Employment (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)

交通分析区（Transportation Analysis Zones，TAZs）被旧金山湾区大都会交通委员会的出行模型与城市模拟模型所采用。此类模型用于预测人口增长、经济增长、交通/公共交通运力与响应性，并将预测结果分发至整个湾区。包含建模结果的数据表将通过区域ID（taz1454）与TAZs要素进行关联。目前可供下载的数据表如下：
1. 《旧金山湾区计划2040》就业预测数据：涵盖总就业量、TAZs辖区就业量、零售业就业、金融与专业服务业就业、卫生教育及娱乐业就业、制造业、批发业与运输业就业、农业与自然资源就业及其他就业类别；
2. 住户数据：包含住户总数与住户收入四分位数；
3. 土地利用与交通数据：涵盖区域类型、工商业用地面积、住宅用地面积、独栋与多户住宅单元数、从车辆停放点至出行起讫点的耗时及小时停车费率；
4. 人口与人口统计数据：包含总人口、住户与集体住宿区人口、分年龄组人口、62岁及以上人口占比、高中入学率与大学入学率。
