In this study, for the purpose of development of structural reliability evaluation method for highway bridges, traffic flow models are proposed, which are quite versatile to be applied to real traffic pattern. The proposed methods are found to be rational to evaluate the performance safety against cumulative fatigue damage as well as corrosion damage under vehicle loads. The sensitivity analysis on cumulative fatigue damage and reliability has been performed to assess the effect of important parameters, such as average daily truck traffic volume(ADTT), average daily traffic volume(ADT), characteristic of consecutive vehicle type, impact coefficient, corrosion parameters as well as bridge types (number of traffic lanes, number of girders, span length), etc. Based on the results the future direction of fatigue design practice has been suggested.
