In a navigation system, which consists of linked relationships with a 'ship-human-environment', to assess the safety of marine traffic, it is needed to evaluate latent environmental stress, stress absorption value and residual environmental stress. By employing real time ship-handling simulator to evaluate residual environmental stress, due to the small sample size and the variance of human factor, the universality of the evaluation result is not so good. Therefore, in order to develop a methodology to estimate residual environmental stress from latent environmental stress, which can be easily evaluated, the authors have carried out a series of research on the relationship between the latent environmental stress and residual environmental stress. In the present paper, as the third report of this research, by employing marine traffic simulation technique, an investigation into the relationship between residual and latent environmental stress in congested traffic is carried out. And based upon the results of these series investigations, an estimation formula of stress ratio is also given. In a given condition, by using the stress ratio, the residual environmental stress can be estimated from latent environmental stress.
