In a pavement state determination method of the invention, the suspension pressure of a self-discharge tramcar (20) in running is detected, a detection value (FR,FL,RR,RL) of the suspension pressure, the maximum amplitude (PP) and the frequency (PPHz) in a given time are obtained, and the pavement state is determined based on the maximum amplitude (PP) and the frequency (PPHz).
