Naturalistic driving study analysing the effect of rainfall on driving behaviour for older drivers

We aimed to determine whether the amount of daily rainfall was predictive of driving behaviour among drivers 75+ years, in regards to driving exposure and the rate at which Rapid Deceleration Events (RDEs) occurred, acting as a surrogate safety event. Naturalistic driving data from 190 drivers aged 75+ years, monitored between one and 12 months was used in this analysis. By applying a T-distribution, we found older drivers tend to drive more during light rainfall (1-2mm] and less during heavy rainfall (10-20mm]. Using logistic regression, we found the rate of RDEs decreases with increasing rainfall, suggesting cautiousness among older drivers.
