What this Trial Is About

The goal of this pragamatic trial is to assess the impact of eco-driving assistance (EDA) system on professional bus drivers' health and well-being. The main questions it aims to answer are: * Does the eco-driving assistance (EDA) act as a stressor for bus drivers ? * Does the physiological and psychological perceived stress increase when bus drivers are driving bus equipped with eco-driving assistance (EDA) ? An additional question consists in assessing the association between stress measurements and biomarkers in biological samples. Researchers will compare the heart rate variability (HRV) and perceived stress level when participant are allocated to EDA-equipped buses and non-EDA-equipped buses Participants will: * Drive buses equipped with eco-driving assistance (EDA) * Drive buses without eco-driving assistance (EDA) * Wear a wearable electrocardiogram (ECG) device (Bittium Faros) to record the heart rate variability (HRV) * Answer a questionnaire at the end of each working day (end-of-service questionnaire) * When allocated to bus with eco-driving assistance (EDA), read the EDA-generated report and answer some related questions in the end-of-service questionnaire * Upon acceptance only, a collection of biological samples and physiological measurement will be performed
