Data & Modelling: Winter 2010


 

The modelling world would seem to be suffering from something of a crisis of confidence at present. No longer is there a long string of articles in this supplement boasting of the immense potential for modelling to add value to the transport planning process (although there are still some in this vein). What the modelling community is currently talking about, apparently, is how we recognise the limits to modelling and ensure that, when models are used, it is just as important that we realise what they can’t do as what they can. So, for example, Robert Bain talks about the usefulness of peer reviews to keep modellers honest, and Mott MacDonald’s Chris White outlines his company’s ongoing attempts to minimise the risk inherent in trying to predict the future via computer modelling. But it is not all doom and gloom. Atkins’ Anan Allos and Somerset County Council’s Emma Cockburn, for example, outline ways in which the raw data upon which all modelling work is undertaken can be improved in the future. And surely this is good news for the modelling community – after all, without good data the whole modelling exercise is futile, remember.
