When Do Drivers Interact with In-VehicleWell-being Interventions? An Exploratory Analysis of a ...
summary
A retrofitted smartphone infotainment system runs two real interventions — a mindfulness exercise and a personalized music playlist — across 10 participants who log 1,009 trips; the study delivers 600 interventions of which 402 started 285 completed. Trip- and 15-second moment-level features (speed, steering, pedal use, GPS, road type, occupancy) predict starts and cancellations: starts cluster on longer, solo, commute trips and steady highway driving, and interventions do not increase critical events but reduce speed violations and harsh steering.
