Modelling World 2016: Complexity in Land Use Transport Models


Giving a paper on Thursday 2nd June in London at Modelling World. Talking about Complexity in Land Use Transport Interaction (LUTI) Modelling, outlining very briefly our QUANT model for the Future Cities Catapult. This model is designed to simulate employment population and the interactions between and the constraints imposed on development for all of England and Wales at the scale of middle layer super output areas. There are 7201 such areas in E&W so to the scale is pretty typical of LUTI models. The model is web-based meaning that you can run it from anywhere and it is designed for anyone in E&W to explore the impact of changes in employment and population, networks time and costs and also land use constraints. Why only E&W? Well we are working in getting Scotland into it but the data is a little different when it comes to the journey to work and related census geographies.

It is early days as yet and we are still very much in the experimental stage of building this – it is in fact a proof of concept – to show we can build tools that are applicable to everywhere – and so far there are very few models like this one. We are stretching the state of the art in that the model, the data and the user(s) all interact with each other across servers and clients. The data and storage and speed implications of all this are pretty immense. More on this once we develop it further. I will post the talk after I have written it but before the session on June 2nd at 16-30pm at the Oval. Drill down for the content of the meeting etc. And here for my PDF of the talk which is hard to see in the meeting

Cities as Flows in a Circular Economy


Podcast: Cities as flows in a circular economy

Wrote a chapter in the new book from the Ellen MacArthur Foundation which I blogged about earlier – click here for details. But each of the chapters is accompanied by a podcast where Colin Webster asks the authors about their contributions. Here is mine – click on image above or here to listen.

How Disruptive is the Smart City Movement?


A couple of months ago I attended a meeting at Wilton Park in Sussex organised by the Uk Government’s Tech City Hub (http://www.techcityuk.com/) and a cloud computing company called Improbable (http://improbable.io/) specialising in massively parallel agent based modelling (for cities, transport, the economy, etc.) which focussed on how disruptive smart city technologies were likely to be. In fact the meeting concluded that the like of Uber et al were not likely to be anything as like as disruptive as first imagined but cybersecurity was likely to be much more disruptive on our way of life. In fact the many layers of digital infrastructure now being added could change the nature of disruption quite dramatically as the world becomes ever more complex. The implications are not as they were once seen and I wrote an editorial in Environment and Planning B sketching out come of the consequences.
