"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."

"The aim of this studywas to examine and compare psychological factors influencing car drivers? andmotorcycle riders? speeding intentions (IN), using the Theory of PlannedBehaviour (TPB). The psychological factors modules included Attitude (AT),Subjective Norm (SN) and Perceived Behavioural Control (PBC). These wereemployed to explain speeding intentions in urban road environments. A sample of188 car drivers and 174 motorcycle riders were collected from the twouniversities within Khon Kaen, Thailand. The Structural Equation Model (SEM)was used to examine and explain speeding intentions. The results indicated thatthe TPB could explain 33% and 41% of the variance of intentions by car driversand motorcycle riders, respectively. The most significant psychological factorfor car drivers was determined by attitude (AT), while the speeding intentionof motorcycle riders was attributed to perceived behavioural control (PBC). Theauthorities in Khon Kaen Province should determine safety policies that canimprove these psychological factors, which could have various effects oroutcomes on changing car drivers? and motorcycle riders? speeding intentions.The outcome of this study could help to understand car drivers? and motorcycleriders? speeding intentions in urban road environments and it could be usefulfor development of safety measures."

"An effective and real-time traffic information network is highly important and could contribute to decreasing traffic volume and costs by reducing fuel consumption and saving time for drivers in reaching their destinations. This study provides an extensive analysis regarding the drivers? acceptance levels of the current implementation of the Intelligent Transport System (ITS) in Kuala Lumpur. A proposed model from the literature review based on the known Technology Acceptance Model (TAM) is introduced. The ITS system characteristics, information quality, system quality, and service quality were investigated as external variables. The resulting analysis showed that information quality is the highest influential factor followed by system quality. The results also revealed that service quality had no effect on acceptance levels."

"In this special edition, we have selected 15 papers from the 4th SEANES International Conference on Human Factors and Ergonomics in South-East Asia 2016, which discussed the application of human factors and ergonomics to current local and global needs."

"The effectiveness of transportation demand management policy depends on how commuters respond to it. This study attempts to comprehend commuter behavior in choosing routes based on electronic road pricing (ERP) policy implementation on the Sudirman and Kuningan corridors. The experiments were conducted using the data collections from a stated preference experiment in which each commuter makes a route choice with an alternative representing a hypothetical situation with a combination of tariffs and travel time in ERP policy implementation. Logit models found that the individual and household variables influence route divert behavior. A commuter with a higher income or more family members living together is more likely to have less flexibility in diverting route. In addition, the distance of the trips affected their route divert behavior and influenced an individual trip chain constrained in time-space prism."

"Thepavement of the nailed-slab system has been proposed as analternative solution for addressing the rigid pavement problem in soft soils.This system is used for developing a rigid pavement. The simple method of using an equivalent modulus of subgrade reaction (k?) in nailed-slab system analysis wasproposed by a previous researcher. This modulus consists of the modulus of subgrade reaction from a plate load test(k) and an additional modulus ofsubgrade reaction due to pile installing (Dk). Theadditional modulus of subgrade reaction has been proposed by some authors. Thedisplacement factor was used in determining the additional modulus of subgradereaction. This factor is difficult to define. In this research, the prototypetest of a nailed slab with single-pile installation was conducted to learn thevalidation of the theory of the additional modulus of subgrade reaction on afull-scale dimension. The prototype was constructed on soft clay, and theconnection between the pile and slab was perfect monolithically. This systemwas loaded by centric load. A new curve of the displacement factor is proposed.Calculated deflections based on thiscurve were compared to the observed deflection andresulted in good agreement with the observation. Hence, it can be used in preliminary design."

"The aim of this study was to examine and compare psychological factors influencing car drivers’ and motorcycle riders’ speeding intentions (IN), using the Theory of Planned Behaviour (TPB). The psychological factors modules included Attitude (AT), Subjective Norm (SN) and Perceived Behavioural Control (PBC). These were employed to explain speeding intentions in urban road environments. A sample of 188 car drivers and 174 motorcycle riders were collected from the two universities within Khon Kaen, Thailand. The Structural Equation Model (SEM) was used to examine and explain speeding intentions. The results indicated that the TPB could explain 33% and 41% of the variance of intentions by car drivers and motorcycle riders, respectively. The most significant psychological factor for car drivers was determined by attitude (AT), while the speeding intention of motorcycle riders was attributed to perceived behavioural control (PBC). The authorities in Khon Kaen Province should determine safety policies that can improve these psychological factors, which could have various effects or outcomes on changing car drivers’ and motorcycle riders’ speeding intentions. The outcome of this study could help to understand car drivers’ and motorcycle riders’ speeding intentions in urban road environments and it could be useful for development of safety measures."
