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

Driving a bus equipped with EDA
DeviceEco-driving assistance (EDA) systems is a technology integrated into vehicles that helps drivers to optimize fuel efficiency and reduce emissions by providing real-time feedback and guidance on driving behaviors. The system typically analyzes several driving behaviours that are measured using different captors and sensors. These systems aim to reduce the overall carbon footprint of driving, leading to cost savings for the public transport company and reduced environmental impact.
Heart rate variability (HRV)
Heart rate variability (HRV) will be measured using the Bittium Faros ECG device. Participants will continuously wear the device throughout their working day and during one full non-working night, to obtain baseline value.
Perceived stress
Perceived stress will be assessed with the validated perceived stress scale questionnaire included in the baseline questionnaire, filled at the begining of the study, once the eligibility has been confirmed. For each question participants will choose from the following alternatives: 0 = never; 1 = almost never; 2 = sometimes; 3 = fairly often, 4 = very often
Perceived stress
Visual analog scale (VAS) for perceived stress during their working days included in the daily end-of-service questionnaire Scale from 0 to 100, with 0 = no stress and 100 = maximal stress
Perceived stress
Specific questions related to any stessful events encountered during the participant's working days included in the end-of-service questionnaire
Stress biomarkers in saliva samples
Saliva auto-collection (upon acceptance only) by participants to further measure cortisone and cortisol and correlate their levels with any participant reported stressful events in the end-of-service questionnaire.
