Abstract

This paper describes the development of a profile-based ride measure, denoted Heavy Articulated Truck Index (HATI) to highlight road sections providing a poor ride to occupants of heavy articulated trucks. The paper also describes the validation of HATI and the assessment of its effectiveness in highlighting poor sections in different regions in comparison with other ride measures. The study results showed that, for the sections tested, HATI is better than the other measures in highlighting sections with characteristics that excite vertical, lateral, longitudinal and rotational responses of an articulated heavy vehicle body. The findings help asset managers better understand the characteristics of pavement surface roughness and road geometry elements that affect a truck driver's perception of pavement rideability and identify candidate sections for improvements.
