Vibration problem of contemporary timber houses caused by traffic disturbance is investigated based on microtremor measurements. The fourteen measurement sites are selecdet in Utsunomiya-city. Displacement records are obtained in these sites and houses in case of calm time and in case of time when cars pass along the roads near these houses. After comparing the dynamic characteristics of these houses and near fields of each time mentioned above, the following results are obtained. The vibration caused by cars mainly consists of Rayleigh type wave. Such waves of frequency range of two to three Hz don't decrease easily, but waves frequency range of more than ten Hz rapidly decrease. The higher the mass ratio (m_0/m_1), aspect ratio (H/R), rigidity ratio (ωR/Vs) and the length of share wall of contemporary timber houses, the higher the natural frequency and the damping property of these houses.
