The results of an experimental road research project are presented which demonstrate the existence of spatial repeatability and show patterns of axle impact forces along a pavement. As part of the project, a section of highway near Paris, France, was instrumented with 18 weigh-in-motion sensors. Data was collected for a large number of vehicles over fourteen days between June 1994 and May 1995. For all the vehicles the impact factors were calculated, and typical graphs are presented which show… Expand
A statistical spatial repeatability algorithm for multiple sensor weigh in motion
The use of an array consisting of multiple WIM sensors is well established as a means of increasing the overall accuracy of in-motion axle weighing. This paper proposes a new algorithm for processingExpand

The use of Bayesian statistics to predict patterns of spatial repeatability
Statistical spatial repeatability (SSR) is an extension to the well known concept of spatial repeatability. SSR states that the mean of many patterns of dynamic tyre force applied to a pavementExpand
