Abstract

Pavement smoothness is one of the main factors affecting riding perception. There are two kinds of theories on how road surface smoothness affects riding perception: one is the widely accepted vibration acceleration (VA), and the other is gyro angular velocity (GAV) of passengers around X, Y, and Z axes. The amplitude and frequency of VA usually cause discomfort in the human skeletal, muscular, and internal organs, while GAV around X, Y, and Z axes causes neural perception discomfort in passengers. This study mainly explores the impact of GAV on riding perception, introduces inertial navigation systems to test GAV, and uses a laser road condition detection vehicle to test international roughness index (IRI). The experimental process selects four roads with significant differences in road conditions, aiming to highlight the impact of rotational movement (RM) on riding perception and to explore correlation between GAV and riding perception, especially for those related to car sickness symptoms such as dizziness and nausea in passengers. Based on three-axis GAV and IRI obtained from on-site test, characteristic value of RM represented by GAV₀ affecting riding perception is calculated. The subjects’ answer to questionnaires are used as neural perception data of dizziness and stomach discomfort.Correlation between GAV₀ and riding perception data is analyzed, confirming that: for subjects with car sickness symptoms, their dizziness symptoms intensify with the increase of GAV0 values. This conclusion can provide a theoretical basis for intelligent driving and policy-making for road maintenance management.
