Public transit accessibility and ridership are affected by neighboring environment along the transit lines. This paper investigates the relations between neighborhood features and bus ridership and emissions of the Chicago Transit Authority (CTA) bus lines. A mixed regression model of bus emissions/ridership model is created to quantify the direct relations with both internal bus operation indicators such as route length and number of stops and external factors including neighborhood land use and population socio-demographics. In Chicago, there are a large number of serviced urban Black neighborhoods with low population in vicinity of bus routes, poor connectivity to transit, and low transit users to work in general, resulting in high per unit ridership bus emissions (grams/ridership) for routes servicing those areas. As the city and the transit agency have been making great effort to increasing bus ridership in those neighborhoods, more collaborative work must be done by the city, the local planning agencies and the transit agency to improve accessibility to bus service.
