Abstract
Statistical analysis of vehicle loads on expressway in Dongying City in China was made to investigate vehicle loads on expressway in recent years. Results show that all the vehicle loads follow multimodal distribution, and cannot be described by a typical probability model. In this paper, the probability density function is simulated by a weighted sum of three lognormal distributions. The three peaks represent light, normal and heavy vehicles respectively. The multivariate extreme value distribution for heavy vehicles is simulated by the Extreme Value I Distribution. Finally the 0.95-fractals of maximum distribution of the three peaks are calculated for different time periods.
