A paper titled “Trip characteristics impact on the frequency of harsh events recorded via smartphone sensors” authored by Armira Kontaxi, Apostolos Ziakopoulos and George Yannis is published online in IATSS Research. Generalized Linear Mixed-Effects Models were fitted to the trips of car drivers who made frequent trips for two experiment phases in order to model the frequencies of harsh events. Results indicate that maximum speed, the percentage of speeding duration and total trip duration are positively correlated with both harsh acceleration and harsh braking frequencies. On the other hand, the exposure metric of total trip distance was found to be negatively correlated with both harsh event types. A small positive correlation of the percentage of mobile use duration with harsh accelerations was also detected.
