Clean fleets, different streets: evaluating the effect of New York City's clean bus program on changes to estimated ambient air pollution.

ABSTRACT:

Background

Motor vehicles, including public transit buses, are a major source of air pollution in New York City (NYC) and worldwide. To address this problem, governments and transit agencies have implemented policies to introduce cleaner vehicles into transit fleets. Beginning in 2000, the Metropolitan Transit Agency began deploying compressed natural gas, hybrid electric, and low-sulfur diesel buses to reduce urban air pollution.

Objective

We hypothesized that bus fleet changes incorporating cleaner vehicles would have detectable effects on air pollution concentrations between 2009 and 2014, as measured by the New York City Community Air Survey (NYCCAS).

Methods

Depot- and route-specific information allowed identification of areas with larger or smaller changes in th
