A Computational Implementation of Jane Jacobs' Generators of Diversity

A Computational Implementation of Jane Jacobs' Generators of Diversity Part of the reason for the frequent recent mentions of Jane Jacobs on this blog is that I’ve been working on developing a ‘Computational Implementation of Jane Jacobs’ Generators of Diversity’ as part of my recently completed dissertation at CASA UCL. Jacobs (quite convincingly) argues that diversity fuels autocata ...

The Valuable Inefficiencies of Cities

The best solutions to problems aren’t always the most obvious. This is why we value creative thinkers and the odd-ball eccentric genius sorts who arrive at fresh new ways of looking at the world. Our cities work the same way. Let me explain. It is a natural inclination to want to build on what we’ve done before; to extend, to refine, to optimise. However, this is also a form of path dependence and [lock-in](https://en.wikipedia.org/wiki/Lock-in ...

An informational localised network centrality measure

I’ve been running some experiments with graph centrality indices in an attempt to find an effective method to describe Jane Jacob’s thinking behind her argument for ’the need for small blocks’. Centrality indices are a manner to identify the most important edges (links) or vertices (nodes) in a graph (network), and can tell you things like which people are the most influential in a social network, or which roads are the most likely to experience traffic and liveliness. In the case of street net ...

The Visualisation Landscape

I’ve spent the last several weeks investigating options for visualising spatial information. Lets just say its been surprisingly frustrating and rewarding at the same time. In a perfect world I’m looking for a visualisation package that is tightly integrated with code, allowing for dynamic user input and on-the-fly visualisation of computational processes as they unfold. Processing My journey started with the ‘ol classic: Processing. But its a bit of a love-hate ...

Measuring Urban Land-Use Diversity

I've been exploring ways to map urban land-use diversity, which is a rather tough nut to crack. The problem is that it requires a reliable source of high quality data that accurately classifies each building occupancy as a type of land-use. After some digging around, I learned that the [Ordnance Survey's OS MasterMap Address Layer 2](http://www.ordnancesurvey.co.uk/business-and-government/produ ...
