A paper titled “Trip characteristics impact on the frequency of harsh events recorded via smartphone sensors” authored by Armira KontaxiApostolos Ziakopoulos and  is published online in IATSS Research. 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. doi
