Data description:

This database called "TMD-CAPTIMOVE" provides transportation mode labelled data collected by 34 volunteers for a total time duration of around 48 hours.

Considered transportation modes are: On-foot (Walking, Stairs, Elevators), Bike, Scooter, Bus, Tram.

The number of labels is 11: Still, Walk, Upstairs, Downstairs, Elevator up, Elevator down, Bike, Electric scooter, kick scooter, Bus, Tram.

Sensor data are: Acceleration (m/s²), angular rate (°/s), atmospheric pressure (hPa), heart rate (beat per minute (BPM)).

The sampling frequency for all data is 32 Hertz.

Files are stuctured as follows:

  • The main folder called "Labelled_data" contains 34 sub-folders, each one corresponding to one user.

  • Each sub-folder contains several files, each one corresponding to a continuous signal frame.

  • Inside each file, each second (1s) of data is separated from the following one by a row of zeros (0).

================================================================================================================================================================

Reading files:

  • 3 first columns: 3 Dimensional acceleration data in body frame (Acc_X, Acc_Y, Acc_Z)

  • 3 following columns: 3 Dimensional angular rate data in body frame (Gyr_X, Gyr_Y, Gyr_Z)

  • 7th column: 1 dimensional pressure data

  • 8th columns: Acceleration magnitude

  • 9th columns: Angular rate magnitude

  • 10th column: Smoothed pressure

  • 11th column: Heart rate

  • 12th column: Sensor placement

  • 13th column: Label

================================================================================================================================================================

Label and sensor placement data coding:

Because machine learning processes are more convenient with arrays, sensor placement and label data were coded into discrete real numbers as follows:

Class labels: 0: Still, 1: Walk, 2: Bike, 3: Elevator up, 4: Elevator down, 5: Upstairs , 6: Downstairs, 7: Bus, 8: Tram, 11: Kick scooter, 12: Electric scooter

Sensor placement data: 1: Hand, 2: Wrist, 3: Pocket, 4: Foot, 5: Waist
