Résumé

Mental workload of cyclists in real traffic is higher in complex traffic situation, such as intersections in mixed traffic, than in simple ones, such as secluded bicycle paths [1]. To avoid overload in those complex situations, cyclists may engage in inappropriate behaviors [2]. Road design may help to reduce mental workload of cyclists at intersections or in mixed traffic situations. Because investigation of different road layouts in real traffic is expensive and would be unsafe in real complex situations, bicycling simulator would be a more appropriate tool to investigate mental workload and behavior of cyclists [1]. Our research project aims to investigate mental workload of cyclists in complex road traffic situations such as intersections or in mixed lanes with different road layouts using a bicycle simulator composed of a virtual reality headset with embedded eye-tracking. Mental workload assessment will rely on different measures, i.e perceived mental workload measured with a standardized subjective scale, the secondary-task technique and physiological parameters based on eye-tracking measures. A preliminary study was conducted to test the possibility to use the eye-tracker embedded in the headset to measure blink rate and pupil diameter to evaluate cyclists’ mental workload.
