For a low-income Cambodian citizen, commuting to and from work is one of the most dangerous parts of their job. In Phnom Penh, the capital city of Cambodia, low-income citizens commute by truck or long-tail remork. This sort of transportation would be dangerous on the road. Thousands of workers get to and from work every day in vans, but this massive transportation system is almost completely unregulated. Most of the drivers are independent contractors, and few receive any training. The number of traffic accidents is increasing every year, especially for low-income groups. This research is a study on the negative experiences of low-income citizen commute and their intentions toward public bus in Phnom Penh. To achieve the research and study objectives, a questionnaire survey was conducted on low-income citizens, such as factory workers. The effects were investigated using structural equation modeling based on data collected from 476 people in Phnom Penh, Cambodia, in August 2022. The model of structure develops with five latent variables: ‘negative experience in a traffic accident’, ‘Service quality’, ‘Perceived value’, ‘Involvement’, satisfaction, and behavioral intention'. For the result, the transport mode of the low-income citizen depends not only on their income but also on public transport availability, job location, and community location. The results of this research could be used to operate effectively and help policymakers develop and implement policies, along with recommendations to improve safety for commuters and their intentions to use public transport.
