Acceleration4TrackProcess Description

Algorithm Description

• process iterates over all pairs of consecutive measurements
  • travel distance
    • computes the distance between consecutive measurements and sums it up to the total distance per track
  • travel time
    • stores first and last time stamp and then computes the travel time (in minutes)
  • mean speed
    • computes the average of all speed values
  • mean acceleration:
    • computes the duration (delta_time) and difference in speed (delta_speed)
    • computes the acceleration (ratio between delta_speed and delta_time; currently only positive values, which means an increase in speed, are considered
