| 摘要： | Wheel wander, or the lateral distribution of wheel loads, is a natural phenomenon observed onpublic-access roadways. Various vehicle types, individual driving habits, wind effects,mechanical alignment of trailers and other factors all contribute to the randomness of wheeltracking (Buiter et al., 1989). Further, Blab and Litzka (1995) identified lane width, vehiclespeed, existing cross-sectional rut-depth and vehicle width as critical factors in the amount ofwander. Figure 1 illustrates an example of a normally-distributed wheel wander pattern collectedin Michigan, which is representative of many open-access facilities (Stempihar et al., 2005). |
