Reliability in port-hinterland interface

The main goal of the ToGRIP project is to develop a data-driven integrated traffic and logistics model that can be used to design interventions (executed by the Port, Road and other authorities) to combat travel time unreliability and to improve logistic operations. Before designing possible logistics interventions, we first need to understand the logistics operational details and the underlying behaviour. Portbase provided transaction data on arrival of container vessels, containers discharged and the (planned) loading time of these containers onto hinterland transport modes for the period 2015-2017. TNO analysed these data, describing distribution patterns and time series analysis (shifting patterns over the years), and derived metrics like the dwell time of containers being discharged (time the container waits to get picked up after being unloaded from the vessel) and the call size of a vessel (number of containers being unloaded during a port visit). These metrics provide the basis for more in depth analysis, like the correlation between high call sizes and long dwell times.
