“…are also key research topics for the improvement of rail transport efficiency. It has to be noted that at the expense of the obvious energy cost increase of a train with its target speed [8,9], an excessively improved target speed will not contribute much more to saving the train travel time especially when the transport distance between neighbouring stops of the train is relatively short [9,10]. Rather than irrationally increasing the target speed of a train, improving the average speed of the train in its entire transport process is the key to the effective reduction of its passenger riding time [11].…”

Comprehensive effect of operational factors on transport efficiency of a high-speed railway train

Original scientific paper Based on computer-aided simulation studies, the comprehensive effect of target speed, Passenger Capacity Utilization Rate (PCUR) and formation of a High-Speed Railway (HSR) train on its transport efficiency is analysed in this research. It is found that if the target speed of a HSR train is no lower than approximately 80 % of its designed top speed, the time expense per unit of the passenger-kilometres completed by this train will be relatively very small when the PCUR of the train becomes more than about 60 %. From the perspectives of both efficiency and sustainability, it is suggested that the PCUR of a HSR ought to be over 60 % and, meanwhile, its target speed should be about 80 % of its designed top speed. In addition, the long formation of a HSR train is preferred if its PCUR can be kept over 60 %.Keywords: high-speed railway train; Passenger Capacity Utilization Rate (PCUR); simulation analysis; target speed; train formation; transport efficiency Sveobuhvatni učinak radnih čimbenika na prijevoznu učinkovitost vlaka velike brzineIzvomi znanstveni članak Na temelju računalnih simulacijskih analiza, u ovom se istraživanju analizira učinak zadane brzine, stope iskoristivosti kapaciteta putnika (Passenger Capacity Utilization Rate -PCUR) i formacije željezničkog vlaka velike brzine (High-Speed Railway -HSR) na njegovu prijevoznu učinkovitost. Ustanovljeno je da ako zadana brzina HSR vlaka nije manja od oko 80 % vršne projektne brzine, utrošak vremena tog vlaka po jedinici putnik-kilometri bit će relativno vrlo malen kad PCUR vlaka postane veći od oko 60 %. I sa stajališta učinkovitosti i održivosti, predlaže se da bi PCUR vlaka velike brzine -HSR trebao biti preko 60 %, a zadana brzina oko 80 % maksimalne projektne brzine. Osim toga, preferira se duga formacija HSR vlaka ako se njegov PCUR može zadržati iznad 60 %.Ključne riječi: formacija vlaka; prijevozna učinkovitost; simulacijska analiza; stopa iskoristivosti kapaciteta putnika; zadana brzina; željeznički vlak velike brzine

“…This proposal was known as the A/b skip-stop plan (see [2]). As illustrative examples, the skip-stop operation mode has been used (and/or is being used) in practice in Santiago de Chile since 2001 [3], in bogota's Transmilenio system [4], in Los Angeles's Metro Rapid system [5], in Singapur's Transit Link [6] and in the bus line that connects the East zone of Seville area with its historic centre [7]. Figure 1 shows four train services that run along a railway corridor with seven stations.…”

The deterministic form is derived from the description and analysis given by [13] in which stations along a line are classified into three groups, A, b and Ab.…”

In many transit systems, operators use skip-stop strategies to reduce travel time of particular train services by not stopping (skipping) at less densely populated stations. This decision of omitting some stops reduces the travel time for the users within the vehicle and increases the speed of operation, favouring the provision of new transit services where are more necessary. In this work, the best A/b stop-skip patterns for a set of transit services along a railway corridor are determined by means a three-phase methodology that includes the formulation of a nonlinear integer programming inspired in the multiple knapsack problem and the application of a heuristic algorithm based on mathematical properties (matheuristic).

This paper addresses recent restoration of skip-stop operation in the Korean urban railway. Most urban railways in Korea were constructed without consideration of skip-stop operation as many other foreign urban railways. The Korean government had been requested to improve service quality, especially in operational speed, and it announced a policy to restore skip-stop operation for the urban railway lines. This paper presents roles of a central government for restoration of skip-stop operation. Besides leading by research and development side in technical solutions, the roles of the government are very important to implement the restoration. As examples of government's roles, this paper addresses Korean government's recent policy to restore the skip-stop operations.
