Smartphone Based Research of Measurement Indexes Related to Bus Riding Comfort

Abstract:

The purpose of this study is to quantitatively analyze the impact of ride comfort and the vibration state of the vehicle during the operation of the bus.The smartphone as a data collection terminal, The multidimensional variables characterizing ride comfort are constructed by statistical analysis of velocity and latitude and longitude data, and obtains the smooth comfort index by the principal component analysis; on the other hand, applied Fourier transform with acceleration data to build vibration comfort index. This paper makes up for past researchs that ignored the running state on the impact of riding comfort. Using smartphonebased acquisition data to constructed comfort measurement indexs is operational. Applied Logit regression model with cruising data and Results indicated that the comfort indexes can objectivity reflect the passenger subjective perception of bus running status.
