APPROACH METHOD FOR FLEXIBLE REALLOCATION OF RESERVED SEATS ON LONG- DISTANCE TRAINS

Finding a reserved seat on long-distance train travel is supported by aids on platforms and within the train in order to keep the passenger's journey as short as possible and to minimise unnecessary walking within the train. The allocation of a seat to a carriage number on the reservation and the consideration of the carriage position indicator devices on the platform provide the opportunity to wait for the arrival of the train on a section of the platform that is close to the reserved seat. Nevertheless, there are various situations in reality in which this can only be achieved to a limited extent. Varying carriage order, the provision of a replacement train or tight transfer connection can lead to the train being entered at an unfavourable position. This is followed by the passenger trying to find a seat on the train which can amount to considerable traffic. Equipped with a flexible seat reservation procedure, this kind of traffic could be drastically reduced. The solution provides the opportunity to reallocate reserved seats in order to minimize the way a passenger has to walk inside the train to his seat. By means of microscopic simulations, various boarding scenarios demonstrate the effectiveness of this approach. Less passenger movement on the train results in an increase in passenger comfort and reduces the space that is required for such movement, which could instead be used for other purposes. On the platform, this procedure means that passengers no longer need to wait for the arrival of the train at a location that is closest to the allocated seat. Instead, passengers can choose a place on the platform convenient to them, without this having a disruptive effect on system performance.
