The aim of this studywas to examine and compare the psychological factors influencing driverspeeding behavior in 3 cities in Southeast Asia, focusing on developingcounties, using the Theory of Planned Behaviour (TPB). Data was collected from570 respondents in the urban areas of Khon Kaen in Thailand, Vientiane in Laosand Phnom Penh in Cambodia. The psychological factors of TPB include attitude(AT), subjective norm (SN) and perceived behavioral control (PBC). Thesefactors were employed to explain speeding intentions in urban roadenvironments. The Structural Equation Models (SEM) was used to examine andexplain speeding intentions. The results indicated that the TPB could explainthe variance by intentions of drivers in Khon Kaen, Vientiane and Phnom Penh at33%, 46%, and84%, respectively. The most significant of the psychological factors for KhonKaen drivers was determined by AT, while the speeding intentions of Vientianedrivers and Phnom Penh drivers were determined by PBC. From this data, theauthorities of each city should create and implement safety policies that canimprove these psychological factors, which could have a positive effect ondrivers?speeding intentions in urban road environments. The outcome of thisstudy could be useful for understanding the speeding attitudes of drivers inthree different countries and would be beneficial for the development andintroduction of preventative safety measures in these countries as well. |
