This paper presents a smartphone-based ride quality assessment conducted on a VIA Rail route in the province of Ontario Canada. The vibration data were collected by different smartphones placed in different locations on the train. The levels of ride quality were subsequently quantified by the two commonly used indices recommended in the ISO 2631:1-1997, and BS EN 12299:2009 standards. The results show that using smartphones for ride quality yields reasonable assessment in a low-cost and convenient manner and identify that the major poor ride quality values are recorded at stiffness transitions such as bridges, level crossing and switches. Limitations of smartphone sensors, and the future plan for improvement of the use of smartphones for evaluation of ride quality has also been discussed.
