1990 CATS Household Travel Survey

The Chicago Area Transportation Study (CATS) 1990 Household Travel Survey was a self-administered mail-out mail-back survey. The purpose of the study was to update existing data on travel patterns and characteristics of Chicago residents. CATS surveyed the region on a county-by-county basis with the Chicago Central Business District in collaboration with the Urban Transportation Center of the University of Illinois. The study gathered demographic and travel behavior data from residents of northeastern Illinois who were 14 years old or older. 19,314 households participated in the survey. The study focused on non-work travel by motorized vehicle and by foot, and residents recorded their trips on a single travel day. Transportation-related variables include trip origin and destination, trip purpose, travel time, mode of travel used, vehicle occupancy, and walking distance (if that transit mode was involved).芝加哥地区交通研究（Chicago Area Transportation Study, CATS）1990年家庭出行调查为邮寄发放、回收的自填式调研。本次调查旨在更新芝加哥居民出行模式与出行特征的现有数据。CATS联合伊利诺伊大学城市交通中心，以逐县为单位对涵盖芝加哥中央商务区的区域开展调研，调研对象为伊利诺伊州东北部地区年满14周岁及以上的居民，收集其人口统计特征与出行行为数据。本次调查共计19314户家庭参与。研究聚焦于机动车与步行两类非工作出行，要求受访居民记录单个出行日内的全部出行行程。交通相关变量涵盖出行起讫点、出行目的、出行时长、出行方式、车辆载客量以及步行距离（若涉及步行交通方式时）。
