Summary
This study investigates whether in-vehicle information systems (IVIS) designed to promote "smart driving"—defined as safe and fuel-efficient behavior—increase driver workload or distraction. Motivated by concerns that the proliferation of IVIS could exacerbate driver inattention, a leading cause of accidents, the research evaluates two prototype ergonomic interface designs: an Ecological Interface Design (EID) that displays integrated, real-time data, and a conventional Dashboard (DB) design that scrolls through priority warning icons. The study aims to determine if these aids can modify driving behavior positively without compromising safety or increasing cognitive load. The researchers conducted a within-subjects experiment using a driving simulator with 25 participants. The design involved three interface conditions (control, EID, and DB) and two driving scenarios (urban and extra-urban). Driving performance was measured objectively through metrics such as mean speed, acceleration, deceleration, and headway. Driver distraction and workload were assessed using a Peripheral Detection Task (PDT), which measures attention to peripheral stimuli, and the Driver Activity Load Index (DALI), a subjective workload questionnaire. The interfaces provided real-time feedback on gear changes, acceleration, headway, and lane deviation. Results indicated that smart driving aids did not increase driver workload or adversely affect distraction. Instead, the presence of real-time feedback led to decreased mean driving speeds and reduced time spent speeding in both scenarios. The DB interface significantly reduced excessive acceleration and deceleration in urban driving, suggesting improved planning and smoother driving styles. The EID interface resulted in significantly lower subjective workload ratings than the DB in urban settings and improved performance on the PDT, with participants detecting more peripheral stimuli correctly. This improvement in distraction metrics was attributed to reduced speeds freeing up attentional resources and potentially encouraging wider visual scanning. The findings suggest that appropriately designed IVIS can enhance driving performance by encouraging safer, more efficient behaviors without increasing cognitive load or distraction. The EID design proved superior in reducing subjective workload and maintaining peripheral awareness, while the DB design was more effective at modifying acceleration and braking behaviors. The study concludes that smart driving aids, when designed with ergonomic principles, can mitigate rather than exacerbate the risks associated with in-vehicle information systems, supporting their integration into future vehicle designs.
