One of the main bridgework characteristics is the riding quality of bridge floor, determining traffic mode and conditions. The riding quality is estimated according to part wear of particular floor. The article describes the results of optimization work on wear determination and traffic condition estimation process. For this purpose the automated program was created which was aimed at labor coefficient reduction and lessening the qualification and subjective opinion impact of the expert, involved in the bridgework examination. On the basis of particular floor part wear one can also determine the main transport service bridgework indices: safe traffic speed, dynamic coefficient and traffic condition category. The riding quality estimation program enables to establish the kinds of maintenance required in the nearest future.
