Abstract
In this paper an operation mode, which is based on the determination of some
patterns for train timetables, is analyzed. For this purpose, a new mathematical
model is proposed to reach the optimized timetable patterns. In real-world
applications, a small deviation from traffic analysis is acceptable, where
passengers should stand more tightly inside the train. As a result, to reach a more
practical and flexible solution, a fuzzy approach is utilized. At the end, a metro
line is studied and the optimum patterns are presented and analyzed. It is found
that in the stop-skipping approach, in comparison with the conventional all-stop
approach, the number of stops reduces by 39%. By this new method, the number
of trains that stop at stations differs according to the traffic that is usually
measured by Passenger per Hour per Direction (PPHPD). Moreover, the
commercial speed increases, and therefore, the number of required trains in
operation reduces. However, this method results in a marked increase in the
passengers’ average waiting time at non-crowded stations.
Keywords: stop-skipping approach, train timetable patterns, fuzzy mathematical
model.
