![]() ![]() The bus drivers felt uncomfortable seating and driving for long hours. Poor design of bus seat was identified as the leading factors to occupational stress among bus drivers. The study used Statistical Package for the Social Sciences (SPSS) to analyse the data and correlation between the contributing factors and occupational stress among the bus drivers. A set of questionnaires consisting of demographic information, stressors leading to occupational stress, and strain of occupational stress was distributed to fifteen bus drivers working in UTM. The objectives of the study are i) to identify contributing factors leading to high stress among bus drivers and ii) to investigate the effect of occupational stress on bus drivers. * Corresponding author: paper presents a study of occupational stress experienced by bus drivers in Universiti Teknologi Malaysia (UTM). If a driver is off work with back pain, for example, records can indicate how their cab environment was set up, ruling out poorly suited driving conditions as the cause.Nur Azizah Arryanie Morshidi 1 and Norazahar Norafneeza 1 ,2 *ġ School of Chemical and Energy Engineering, Faculty of Engineering, Universiti Teknologi Malaysia, 81310 Johor Bahru, Johor, MalaysiaĢ Centre of Hydrogen Energy, Institute of Future Energy, Universiti Teknologi Malaysia, 81310 Johor Bahru, Johor, Malaysia This also brings with it traceability benefits. This technology improves driver ergonomics without the hassle of manual adjustment. ![]() Suddenly, concerns over time expenditure are no longer valid. This removes the human error of a driver adjusting a pneumatic column to where they ‘think’ is correct. A driver can scan their key fob upon entry, and the steering column, dashboard, mirrors and seat will adjust to the driver’s pre-recorded ideal position. Most impressive is the memory feature of this technology. The technology, in collaboration with Continental and seat manufacturer Isri, has made the entire cab environment adjustable with the touch of a button. Pailton Engineering is developing an electric memory steering column for commercial vehicles, based on technology nurtured in the automotive sector. Luckily for the concerned fleet managers, new automation is making this higher level of cabin adjustment easier and faster. They may question the long-term health and safety benefits of ensuring every driver is in the optimal driving position, compared with the time and energy expended on these recurring adjustments. Yet for commercial vehicle operators, the thought of fully adjusting the entire cabin environment, including seat, mirrors, steering column and dashboard, for every driver on every shift, may sound too time-consuming and costly. For Pailton Engineering, an engineering business that has a unique market position offering bespoke, non-standard design, this trend is exactly its forte. Going forward, as more vehicle original equipment manufacturers (OEMs) follow suit, the interface between the steering column and the dashboard will likely require bespoke design, as catalogue steering parts may not interface the dashboard correctly. This paradigm has changed the engineering requirements of steering columns. When the driver adjusts the steering wheel, the dashboard follows that adjustment, ensuring the driver can reach all the switches and see all the gauges without strain. By building a full dashboard assembly, the entire dashboard is adjustable in both the tilt and telescope direction. Rather than considering the steering column and dashboard as two separate entities, where the steering column is adjustable and the dashboard is fixed, they work in conjunction with each other. The office cab concept counteracts this issue. ![]() In an office space, it is already well appreciated that ensuring an employee’s workstation is comfortable will enable better work and healthier staff in the long-term, but for drivers of commercial vehicles, such considerations have been lacking. It puts people first and aims to ensure the equipment and environment fits the human. Ergonomics is the science concerned with the fit between people and their work. If we are going to keep commercial drivers safe and healthy, design engineers need to factor in a higher level of ergonomic consideration in the early design stages. Just as an office worker has the flexibility to change seating position, adjust screen height and keyboard location, the bus driver should feel just as comfortable and physically supported. The entire vehicle cabin should be, and can be, as ergonomic and adjustable as the conventional office workplace. The bus is their workspace, and operators are beginning to see the importance of creating a workspace that the driver can be proud of. Drivers are in the cabin for eight hours a day. ![]()
