The objectives of this paper were to investigate the preferences of public transit users in general, and illegal passenger van users in particular, towards several level-of-service (LOS) attributes, and to exploit such insights in the planning of future services. The principal survey was drawn from illegal passenger vans. The survey involved two basic SP experiments: first a mode choice experiment considering the public transit modes of passenger van and bus; and second, a within-mode choice between two alternative passenger van services. Both choice experiments were further separated into two, each part considering a different subset of LOS attributes, but both parts including the common attribute of fare to permit subsequent merger. The first part considered walking distance, waiting time and comfort, and the second part in-vehicle time, number of stops and safety. In addition to SP data, RP data was also collected from each respondent. From such models, calculations of willingness-to-pay for LOS improvements will be derived, and future demand under alternative policy scenarios forecast. This finding will contribute towards the future provision of illegal passenger van within a transportation system. (a) For the covering entry of this conference, please see ITRD abstract no. E214938.
