Dividing Journeys in Milestones – A passenger (agent) trajectory reference

Abstract

A journey is more than the connection between starting point and destination. Each person, each cargo passes through several stations until it reaches the desired destination. These stations can pass through similar processes despite the different transport modes and their dimensions (cf. Engler et al.). While the passenger waits at the airport security for the screening of the hand luggage, the cargo container at the port is also checked by customs officials. Both processes have the same objective, namely to investigate the traveling person and the container, for illicit items. It is evident that the start and end points of these processes should be given a similar designation. Dividing journeys in milestones frames a concept for research of interdependencies and interactions between planning and execution of travel chains from the infrastructure owner's and traveler's points of view.
