This paper discusses two urgent problems that need to be solved in fully automatic operation (FAO) for urban rail transit. The first is the analysis of safety in FAO, while another is the analysis of efficiency in FAO. Firstly, this paper establishes an operational safety evaluation index system from the perspective of operation for the unique or typical risk sources of the FAO system, and uses the analytic hierarchy process (AHP) to evaluate the indicators, analyzes various factors that affect the safe operation of FAO, and provides safety management recommendations for FAO lines operation to maintain the FAO system specifically. Secondly, taking the Yanfang Line as an example, this paper uses OpenTrack software to analyze the efficiency of FAO operation, and conducts simulation calculations for key links such as the mainline tracking interval, train entry and exit, and return limit interval. The fault impact surface of the FAO trains is simulated and discussed to verify whether FAO can meet the long-term operation requirements of Yanfang Line. Finally, this paper compares the simulation data of FAO on the Yanfang Line with manual operation (MO) to verify the advantages of FAO and guide the engineering construction of subsequent fully automated driving lines.

“…Publications in the field of railway transport research are usually focused on railway line technology or on railway stations. The paper [2] follows line technology and it searches for balance between train speed, travel time and energy consumption by riding between two stations. Example dealing with stations is [3], which considers using of hybrid Petri-net for simulation of railway station operation.…”

Rail transport plays an important role in the vision of the development of mobility in the European Union. This is reflected in modernisation projects that include not only railway lines, but also station layouts. Unfortunately, many examples in the Czech Republic and Poland show that the 'rationalization' of the number of tracks and switches often leads to situations in which the station is no longer useful for rail traffic that would be even slightly different from the assumed standard. Currently, a simulation model is being developed to assess the modernised stations in terms of their usefulness for rail traffic. This article presents the so far solved problems related to the aspect of time, as well as track prioritisation when accepting various types of trains. It also contains the currently tested version of developed algorithm, which allows simulating the operation of stations in random traffic conditions.

“…As for the research trainsets, the 151.0 engine with 7 Bmz coaches, Škoda 109E with 7 Bmz coaches, Siemens Viaggio Comfort non-traction unit with Taurus engine and multiple units of the 680 ČD "Pendolino" series, AVE, and ICE 3 were chosen. For a more detailed description of the model, see previous article [19].…”
