Measuring Comparative Public Transport Accessibility for GB Cities

Posted on Monday 29 January 2024 by Duncan A Smith

While Greater London has a comprehensive transit network, this is not a fair representation of UK cities where underinvestment and privatisation has seen many bus, metro and rail networks stagnate in recent decades, falling well behind European and Asian peers. Improving public transport is an important aspect of addressing the UK’s high regional inequality and … Continue reading Measuring Comparative Public Transport Accessibility for GB Cities →

Spatiotemporal Variation in Travel Regularity

Posted on Tuesday 27 November 2018 by edmanley

It seems life and work is less than compatible with #content generation for this blog, so ‘why don’t I just’, I figure, ‘write a short piece about the research I have been doing in all this time’. I also figured this was a good idea, so here is the first in what I’m going to …

Understanding Cities through Individual-Level Data – Opportunities and Challenges

Posted on Wednesday 21 September 2016 by edmanley

As it’s been a while since I last posted, I thought I’d put up something I prepared for a Royal Society Smart Cities and Transportation workshop next week. I’ve focussed on data collected at the individual-level, and the opportunities the data present for better understanding cities, and the challenges the maximisation of these resources face. There are no …

Mapping Connected Places on London’s Public Transport Network

Posted on Wednesday 12 March 2014 by edmanley

I haven’t written much on this blog about the work I’m currently doing at UCL CASA. As a Research Associate working on the Mechanicity with Mike Batty, I’m tasked with drawing meaning out of a massive dataset of Oyster Card tap ins and tap outs across London’s public transport network. The dataset covers every Oyster …

Bike webs

Posted on Wednesday 11 September 2013 by Martin Zaltz Austwick

The paper we published in PLOS ONE last week covers bike share schemes from five cities: the large ones in London and Washington, DC, and smaller ones in Boston, Minneapolis, and Denver. It might seem odd that we’ve chosen these … Continue reading →

Identifying Communities in Traffic Flow

Posted on Monday 26 November 2012 by edmanley

Edit: See new Central London image below! One recent bit of research I have been working on has been looking at the application of community detection algorithms to traffic flow in London. The idea is that within the traffic system exist a number …

London 2012: Using Fear to Tame Transportation Demand

Posted on Monday 30 July 2012 by edmanley

One of the biggest advantages, I feel, about studying urban transport phenomena in London is the simple ability to be able look out of the window and see what is actually going on. This week, the Olympics and its (supposed) transportation chaos, c…

Navigating the City: Minimising Distance but NOT Minimal Distance

Posted on Wednesday 20 June 2012 by edmanley

I’ve always had a problem with the pervasive assumption in transportation research that everyone takes the shortest metric distance path when travelling between A and B. This idea doesn’t seem to have any solid foundations in research, and intuiti…

Modelling Movement in the City: The Influence of Individuals

Posted on Tuesday 1 May 2012 by edmanley

‘Modelling Movement in the City: The Influence of Individuals’ was the title of a talk I gave at the AGILE conference in Avignon, France last week. For the conference I actually initially prepared a poster that never ended up seeing the light of d…
