The calibration of trip distribution models
In this paper, model calibration is considered in terms of the evidence supplied by a survey to substantiate the distributional hypothesis implied by the model. By means of Bayes theorem, an evidence...
On the geometry of emergency service medical provision in cities
The enormity of many cities today poses special problems for authorities supplying emergency medical services. The scale of the emergency system and variations in the operating conditions rule out...
The city is not an undifferentiated terrain and travel does not occur along straight-line paths at constant velocities. Variations in travel velocities at different locations bend the minimum time...
This paper centres on the development of a geometrical representation of movement and spatial interaction in urban areas, as distinct from the network representation commonly used in modern studies....
