摘要：	Studying the Houston-Galveston Transportation Management Area (TMA), revealed that of the 1062 census tracts, about 356 (34%) tracts were classified as EJ Zones. Among EJ tracts, 209 (20%) were low EJ, 107 (10%) were medium EJ, 32 (3%) were high EJ, and 8 (1%) were extreme EJ tracts. The research team was interested in learning what made eight of the EJ zones fall into the severe category. This study offered an in-depth analysis of these eight most severe environmental justice zones. The research team developed community profiles for the eight tracts. Data collected included demographic and socioeconomic characteristics, transportation mobility accessibility, and travel times to three select activity centers: the Central Business District (CBD), Texas Medical Center (TMC), and Galleria. In general, as the study areas moved away from the CBD, car ownership increased, with Greenspoint reporting the lowest percentage of households without vehicles. Nonetheless, most study areas had good access to public transportation; however Third Ward had the most access to transit and light rail (LRT). The Third Ward EJ zone is also the closest to the CBD. In most cases, residents in these severe EJ zones could travel to various areas of the city. Travel times to major activity centers varied from one hour to 30 minutes based on proximity. As expected, transit trips proved double to triple the amount of time when compared to the same trip made by automobile.
