Urban taxis and air pollution: a case study in Harbin, China

Version 2

    Abstract :

    Taxis share a high proportion of urban traffic volume and contribute a large proportion to urban air pol-
    lution. This paper addressees this context by exploring urban taxi air pollution emissions and possible
    reduction countermeasures. Based on a survey of Harbin taxis, we have developed different urban taxi
    pollution emissions models and considered taxi passenger occupancy and taxi average vacant ratio. To
    reduce taxi air pollution emission, this paper sets a reduction goal and puts forward three kinds of trans-
    port management policies. These are taxi market regulation, introduction of electric and Liquefied Petro-
    leum Gas powered vehicles, and the introduction of dial-a-ride services. The paper provides
    recommendations for managing urban taxi development using these strategies.
