Abstract:
In accordance with the existing problems, that current analysis methods for vehicle loads using an approximate distribution obtained by fitting as a base distribution of extreme value estimation, which might cause a significant error for extreme values, new methods for extreme value statistics were introduced, including threshold model, order statistic measurement model and point process model. In order to obtain the probability distribution tail and the maximum value distribution of heavy truck loads, these new models were respectively adopted to analyze the samples of type 5 vehicle weight on Guangzhou North-ring Expressway. The comparisons between results from the new extreme value statistic models and those from the current method were carried out. The results show that the estimations from the threshold model and the point process model are more consistent with the measured samples, whereas the results from the current method show errors. Moreover, to a certain extent, the value of estimation load from the current method undervalues the extreme value of vehicle loads.
