Methods for a determining a normalized lane occupancy and for monitoring signal quality for a vehicle detection system. Such methods include, in one embodiment, measuring a speed of a vehicle with an inductive vehicle detector, measuring an on-time for the vehicle crossing a wire loop sensor of the inductive vehicle detector, determining an inductive length of the vehicle from the measured speed, and computing a normalized on-time by subtracting a longitudinal length of the wire loop sensor from the inductive length and dividing the difference by the measured speed.
