Abstract
Errata: Communications - Scientific Letters of the University of Zilina, 21(1), 2019, Passsenger Ride Comfort and International Roughness Index Specifications in the Slovak Republic, p. 15-22.
Highlights
Authors have identified incorrect results in their paper [1]
The comparison is influenced with an unequal number of segments N in groups and higher mean speed by 30 to 40 km/h on motorways on the section of the same road class
For the same IRI road class, the median total passenger vibration was about 10-20 % higher on motorways
Summary
Authors have identified incorrect results in their paper [1]. Trend removal of measured acceleration signal in Matlab code was inadvertently not turned on. Whole-body vibration and IRI road classes ... Median av value (P50) exceeds the lower bound of expected “fairly uncomfortable” human reaction (av = 0.5 m/s2, Table 1) for two IRI road classes (#2 and #3) and motorways and three IRI road classes (#3–#5) for the 1st and 2nd class roads (Table 4).
