ABSTRACT

The vibration level depends on road/railway performances (roughness, structural condition) and on traffic characteristics (speed and vehicle weight). Traffic vibration frequencies recorded by Barneich (1985) in different spots with different road/railways and traffic conditions are presented in Table 1. Figure 1 displays the vibration tolerance thresholds recommended by Standard DIN 4150 (1999), upon which the curve of the car and bus traffic vibration measurements carried out in Bogotá is superimposed (Caicedo 2007). Here bus and car traffic generates vibrations standing principally within the limit considered as “troublesome to persons” but which may occasionally reach the “severe to persons” threshold.
