عوامل موثر بر قابلیت اطمینان و ایمنی تراموا

The paper presents the factors have influence on the operation process safety of tramway rolling stock, and in consequence will have influence on service intervals. The main goal is to collect a set of factors, which will be important for planning of infrastructure and rolling stock operation research. After reviewing the state of knowledge, the paper presents a general analysis of the tram rolling stock subsystem. Then sources of data on the operation process were described. In later, processes occurring in operation and maintenance of tram vehicles were identified. Also influencing factors due to each process phase were described. Then a concept of operation research for a new rolling profile of wheels was introduced. The paper ends with a summary and further research perspectives.
