Disposable income is found to be the dominant factor in determining the purchase probabilities of car engine size, but in addition a combination of high population density and the availability of rail transport can reduce the demand for medium and large engine sized vehicles, as well as for new cars generally. Bus services, however, only serve as a substitute for small engine cars.2167808 bytesapplication/mswordenThis is the author’s version of a work that was accepted for publication in Transportation Research.
