To enhance the visibility of bridge frequencies, an effective filter is needed to filter out the vehicle frequency.
Stability maps for varying velocity of the vehicle, frequency and amplitude of the force oscillations are obtained.
When a linear vehicle model is used, vehicle Frequency Response Functions (FRF) facilitate the calculation of the axle loads [2, 3].
On the other hand, the vehicle responses are governed by five distinct frequencies that appear as driving frequencies, vehicle frequency, and bridge frequencies with shift.
One problem with this approach is that the vehicle frequency (undesired) usually appears as a dominant peak in the spectrum, making it difficult to identify the bridge frequencies (desired).
It is concluded that the point model tends to introduce some unrealistic high-frequency vibrations on the system responses, while underestimating the amplitude of vehicle frequency in the vehicle response.

The latter has implications for damage detection because if the frequency content of the 'damage' component includes bridge and/or vehicle frequencies, it becomes more difficult to identify damage.
These results clearly show the effect of size of beacon, velocity of vehicle and frequency of beacon.
It is noted that the thrust force reduces the vehicle natural frequency while mass consumption increases it.
Statistical models, such as Poisson or negative binomial regression models, have been employed to analyze vehicle accident frequency for many years.
The Fourier transform of the loading function describes how the passage of repeating vehicles within a train leads to spectral peaks at various multiples of the vehicle passing frequency.
