This paper investigates the attitudes of paratransit drivers towards the newly-introduced public bus in Phnom Penh and their intention to operating as feeder service of the bus. We developed a structural equation model using data collected from drivers of Motodops and Remorks. We found that Motodop drivers intended to operate as feeder service of the bus, regardless their attitudes towards the bus. Remork drivers cautiously anticipated the negative impacts of the bus on their livings and accordingly, they had no intention for its feeder service. A better regulation on paratransit service was likely to encourage intention of feeder service.
