Typology of U.S. transit systems reveals energy data gap and potential for diesel-based emissions reductions
We present a typology of 2205 U.S. transit systems, derived from 167 operational indicators in the National Transit Database, to reveal distinct patterns. Using kernel principal component analysis and Gaussian mixture modeling, we identify five distinct transit system types: Metro Bus–Rail , Mid-Siz...
