A number of physical methods are used to survey railway track ballast to assess its degradation as a function of deposition. Simulation tests on track models are also conducted. These testing methods, which are generally labour-intensive and expensive, provide an accurate understanding of the extent of ballast degradation. However, the impact of inadequate maintenance can be observed, even on the...
Urządzenia sterowania ruchem kolejowym odpowiadają za bezpieczne i sprawne prowadzenie ruchu kolejowego. Mimo ciągłego rozwoju tych urządzeń, podobnie jak inne urządzenia techniczne, ulegają one uszkodzeniom. Ze względu jednak na fakt, że urządzenia sterowania ruchem kolejowym są związane z bezpieczeństwem, wymaga się od nich nie tylko określonej niezawodności, ale również braku niedopuszczalnego...
The paper presents possibilities of application of genetic algorithms in design of public transport network. Transportation tasks such as determination of optimal routes and timetable for means of transport belong to difficult complex optimization problems, therefore they cannot be solved using traditional search algorithms. It turns out that genetic algorithms can be very useful to solve these transportation...
