Spatiotemporal Modelling of Transport Demand

Urban Freight Transport Demand Modelling: a State of the Art

The paper provides a review of freight transport demand models for applications in urban and metropolitan areas. The perspective adopted is the short-term one of public decision-makers involved in transport planning and traffic management. The paper recalls the general methodology to be used for assessing the city logistics scenario and the features of models in relation to the planning horizon...

Modelling Public Transport Corridors with Aggregate and Disaggregate Demand

Traditional microeconomic modeling of public transport (usually a single line) has been based on aggregated demand description, that is, total ridership along a line and average journey length. This way, aggregation is spatial rather than temporal, as most public transport systems are designed for the period of largest demand. With this approach, various authors have formulated optimization mod...

Modelling of Sediment Transport in Beris Fishery Port

In this paper, the large amount of sedimentation and the resultant shoreline advancements at the breakwaters of Beris Fishery Port are studied. A series of numerical modeling of waves, sediment transport, and shoreline changes were conducted to predict the complicated equilibrium shoreline. The outputs show that the nearshore directions of wave components are not perpendicular to the coast whic...

Modelling Spatiotemporal Information: The Spatiotemporal Object Model

Many of the data-models developed for temporal databases are extensions of existing non-temporal models. However, to create models which complies as much as possible with the behaviour of phenomena in the real world, we have suggested using an ontological approach using conceptual modelling techniques. The spatiotemporal object model (STOM) introduced in this article is developed using object-o...
