Probabilistic analysis of live load for highway bridges is made by applying vehicle load models measured on an urban expressway. In the analysis, the probability distribution of lifetime maximum response is estimated numerically by convolution integral based on combination of target vehicle on viewed point and train of congested vehicles. Additionally, the stochastic properties of live load are examined theoretically by using truncated exponential distributions for each vehicle load, and results show that upper bounds of vehicle loads especially of large size trucks and trailers are dominant to the lifetime maximum response and that the extrapolating mutiplication of powered probability distribution can not be sufficiently applied to estimate it.
