Seat capacity and hyperpath choice on-board: alight or remain seated?

Abstract

The rationale for the definition of a set of paths referred to as “hyperpath” is that some uncertainty (for example waiting time) means that the choice of a specific option is not being pre-determined. Rather the choice process is assumed to occur on two levels. At a “strategic level” a passenger defines a set of paths any of which might be potentially optimal, and at “a tactic level” a specific path out of these is chosen depending on events occurring en-route. This paper discusses that the same concept of hyperpath might also be true for passengers already on on-board a transit vehicle. The uncertainty in this case arises from the seat availability. The paper extends an earlier version of the frequency-based transit assignment model with seat capacity by Schmöcker et al (2009) to describe that passengers choose their alighting point depending on whether they have obtained a seat or not. This behaviour is compared to the “deterministic” case where passengers have decided their alighting point independent of whether they might obtain a seat or not during the journey.
