Abstract: A system and method for monitoring personal mobility vehicles in urban environments, comprising a double magnetic coil (1), disposed at an area of personal mobility vehicle traffic, and connected to an oscillator circuit (2), a phase-locked loop (3), a signal conditioning circuit (4) and a signal processor (5); where the signal processor (5) is configured to calculate the temporal variation in voltage (V(t), V?(t)) produced in the phase-locked loop (3) and due to a variation in the oscillation frequency of the double magnetic coil (1) when at least one personal mobility vehicle passes said double magnetic coil (1); and to establish the type, speed, direction of travel and length of the personal mobility vehicle that has generated the variation in the oscillation frequency of the double magnetic coil (1).
