Statistical modeling of vehicle emissions from inspection/ maintenance testing data: an exploratory analysis

摘要

Many metropolitan areas in the United States use vehicleinspection and maintenance(I/M)programs as a means of identifyinghigh-polluting vehicles. While the effectiveness of such programs isdebatable, the cost is undeniable, with millions of dollars spent intesting and millions more lost in the time motorists expend toparticipate in such programs. At the core of these costs is theblanket approach of requiring all vehicle to be tested. This papersets the groundwork for a procedure that can be used to selectivelytarget those vehicles most likely to be pollution violators.
