摘要：	Between 1955 and 1994, various successful development activities were carried out in Hungary in order to create several elements of a future bridge management system. In 1995 it was decided to adapt the American PONTIS bridge management system to Hungarian conditions. As an integral part of these adaptation activities also, the deterioration and the condition improvement matrices (Markov transition probability matrices) had to be transformed. When carrying out this adaptation, Hungarian time data series, Hungarian expert elicitation and the original American PONTIS matrices were utilized. Since the bridge elements in both countries are not identical, special rules had to be followed when the "do nothing" type matrix elements of various sources were combined. The creation of "do something" type matrix elements for the PONTIS-H (Hungarian) system was performed in a similar way, although the limited experience of Hungarian bridge specialists in the large variety of bridge intervention technique types caused some difficulties here. The term "environment" is interpreted more widely in the PONTIS-H than in the original version. The first approximation of the PONTIS-H deterioration and condition improvement matrix elements will be developed further in the future by comparing the actual and the long term condition distribution of bridge elements, as well as by the sensitivity analysis of deterioration matrix elements.
