"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."

"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."

"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."

"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."

"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."

"An active Radio-Frequency Identification (RFID) tag is a low-power device, which is often used as a tracking device, where operation of this tag will be in remote areas from an electrical power source. Therefore, this device requires an independent power source. To meet these needs, solar power may be used, which can be accessed anywhere there is sunlight. Supercapacitors (SC) are used as an energy source to support a solar power system. The advantage of supercapacitors, as an energy storage device, is their long life cycle that means more charging and discharging processes compared to a conventional battery. The design and fabrication of a solar power system for an active RFID tag with supercapacitors as the energy storage will be covered in this paper."

"in this paper, a 4.2GHz collinear antena is designed to be used for computer management of vehicles/communication utility that can be integrated into combat systems, that is air defense systems (ADS) and combat field management systems (CMS)."

"In this paper, two highlysensitive photonic crystal fiber (PCF) structures with microstructure core and claddinghave been demonstrated for Ethanol sensing. Themicrostructure core of both proposedPCFs is designed with supplementary holes in an octagonal formation. We have investigated therelative sensitivity and the confinement loss of the proposed PCF structuresemploying a fullvectorial finite element method (FEM). The proposed PCFs work at a widetransmission band covering 0.8 µm to 2 µm and exhibit high sensitivity and lowconfinement loss simultaneously. The numerical analysis shows that the circular shape of air holes in the first ring is a moresalient attribute forincreasing sensitivity and the presence of the square shape of air holes in the first ring showsbetter performance to reduce confinement loss."

"A mechanical assembly consists of several components to perform an intended function. At the design stage, the intended function must be converted into critical product dimensions. After determining the dimensions, a designer must determine the assembly tolerance and allocate this tolerance to the tolerances of the corresponding components. After determining the optimal tolerances, process selection must be conducted along with production allocation to the selected process. There are three aspects in commercial competition that must be considered by a manufacturing company: cost, quality, and delivery. The aim of this research is to develop an optimization model for process selection for a make to order company to minimize manufacturing cost, quality loss, and lateness cost. The model attempts to determine optimal tolerance and production allocation, which takes into consideration the production capacity and process sequence. Hence, the model attempts to include not only the product design decision, but also to solve the process selection and allocation problems. A numerical example is provided to show the implementation of the model."
