Pavement roughness evaluation method based on the theoretical relationship between acceleration measured by smartphone and IRI

International Journal of Pavement Engineering, 2021
Smartphones have integrated various sensors (e.g. GPS, acceleration sensor) and can be used to evaluate roads roughness. In this study the theoretical algorithm, in which the vehicle suspension parameters were included, would be established to calculate ...

Evolution of Pavement Winter Roughness

Transportation Research Record: Journal of the Transportation Research Board, 2005
The functional service level of roads is quantified in terms of roughness. This parameter considers every road surface defect that causes passenger vehicle discomfort. Roughness is measured by a quality index, the international roughness index (IRI). Roughness gives an overall appreciation of road profile quality without, however, permitting a deeper ...

Development of a Simulated Three-Dimensional Truck Model to Predict Excess Fuel Consumption Resulting from Pavement Roughness

Transportation Research Record, 2021
Excess vehicle fuel consumption, the percentage change in fuel consumption caused by road roughness, is an important part of the environmental and cost assessment of a pavement’s life cycle.

Estimating pavement roughness using a low-cost depth camera

International Journal of Pavement Engineering, 2021
In a continuation of the Wyoming Technology Transfer Center (WYT2/LTAP) efforts to minimise the costs associated with the pavement condition assessment process, this study examined the capability of a low-cost depth camera (D435i) in measuring the ...

Investigation of the effect of pavement roughness on crash rates for rigid pavement

Journal of Transportation Safety & Security, 2015
ABSTRACTPavement roughness may have a significant impact on traffic safety, but its effect on the overall safety problem needs to be studied and quantified. This article investigates the relationship between International Roughness Index (IRI) and crash rates by looking into traffic safety performance over time under changing pavement conditions ...

Rough Set Theory in Pavement Maintenance Decision

2009
The decision tree models based on pavement experts' experiences are usually used to derive pavement maintenance decisions. Because experiences are very difficult to obtain completely, some importance condition attributes in decision tree model are easily to be lost.

Modeling for pavement roughness using the ANFIS approach

Advances in Engineering Software, 2013
The term ''present serviceability'' was adopted to represent the momentary ability of pavement to serve traffic, and the performance of the pavement was represented by its serviceability history in conjunction with its load application history. Serviceability was found to be influenced by longitudinal and transverse profile as well as the extent of ...
