1. A vehicle information estimation system comprising:
at least one sensor configured to detect elastic waves generated from a structure and output an electrical signal representative of the detected elastic waves;
an electronic signal processor comprising:
an electronic filter configured to eliminate noise components from the electrical signal output by the at least one sensor and output a noise-eliminated electrical signal; and
a vehicle count estimator configured to estimate the number of vehicles that have passed through on the structure using the noise eliminated electrical signal output by the electronic filter.
