DB Cargo AG has equipped its freight wagons with modern telematics equipment. Various sensors provide with regular frequency and also event-based data.
This dataset contains information on larger impacts, measured by an accelerometer on the wagon.
wagonID = Unique ID of the freight wagon
latitude = geographic width
longitude = geographic length
speed = GNSS speed of the car in km/h
delta_timestamp = measurement time relative to t0
shock_duration = duration of shock event in ms
shock_x_axis = raw data for the x-axis in g at 500 Hz
x_axis = Max. amplitude for x-axis in g
shock_y_axis = raw data for y-axis in g with 500 Hz
y_axis = Max. amplitude for y-axis in g
shock_z_axis = raw data for z-axis in g with 500 Hz
z_axis = Max. Amplitude for z-axis in g
With the help of the data, a categorisation of the impacts in e.g. Shunting, stretching and loading rush. In addition, conclusions could be drawn on route quality or damage to the freight wagon (CBM).
