1. A vehicle transportation installation by cable, comprising:
a cable to haul a vehicle,
a frame mounted stationary,
a bull-wheel coupled to the cable and mounted rotatable on the frame so as to be able to drive the cable, and
a measurement device mounted on the bull-wheel and configured to measure at least one data item concerning movement of the bull-wheel,
wherein the measurement device comprises:
a gyroscope configured to measure at least an angular speed and at least an angular acceleration of the bull-wheel along a rotation axis of the bull-wheel and/or an accelerometer configured to measure at least a speed and at least an acceleration of the bull-wheel along a translation axis of the bull-wheel, and
an electronic control unit configured to develop parameters from the measured data, the parameters being braking parameters developed from the speeds and accelerations measured by the accelerometer and/or gyroscope, the braking parameters comprising at least one of a braking distance, a braking time, an initial braking rate, and a braking curve, the braking curve corresponding to the speeds of the bull-wheel versus time when braking takes place, the braking distance corresponding to the distance travelled by the cable when braking of the bull-wheel is performed.
