This paper presents a evaluation method of the highway pavement performance. The highway pavement performance is affected by a variety of factors, the evaluations of which are subjective at the same time. Therefore, we propose a fuzzy comprehensive evaluation method, which can enable it that comprehensive evaluation of multiple factors is feasible. According to the highway pavement performance evaluation...
According to relevant factors including pavement condition index, structure strength index, subgrade condition index and other factors, a grey clustering analysis method was applied to evaluate the highway condition in this paper. Highway condition was divided into five grey sorts, such as excellent(A-level), good(B-level), average(C-level), sub(D-level) and poor(E-level). Base on the grey clustering...
In order to quantitative analysis the characteristic of drivers' visual search behavior, the paper proposed the conception of Visual Interesting Region(VIR), which includes area and barycentric coordinates two indexes. Firstly, the paper carried out the laboratory experiment and outdoor testing, and obtained the eye movement indexes. Secondly, the indexes of the area and the barycentric coordinates...
