CAPACITY VS. RELIABILITY IN RAILWAYS: A STOCHASTIC MICRO–SIMULATION APPROACH
Last modified: 2017-02-28
As a result, quantitative methods have to be used, which allow a precise capacity estimation, also considering different timetable scenarios, interlocking systems and infrastructure layouts. Moreover, since a high traffic reliability level has to be offered, the effects of increasing traffic on punctuality have to be taken into consideration while estimating capacity.
In this paper a methodology is presented, one which allows a precise estimation of the trade– off between capacity and reliability on railway networks and identifies the system bottlenecks. This methodology is based on stochastic micro–simulation of rail traffic, which has been calibrated using extensive real life data. The successful results obtained using the methodology in important sections of two Pan–European corridors are described and discussed in the second part of the paper. The first case study deals with the network between Trieste and Venice, on the Corridors N.5 and 23; it plays a crucial role at a continental level, since it represents the connection between Italy and all countries of Central and Eastern Europe. The second application focuses on the Croatian part of the X Corridor (Dobova–Zagreb–Tovarnik), which connects Germany and Austria with the Balkan Area.
