Borough Update Meanwhile, the borough-by-borough rollout of dockless in London continues. Wandsworth has a forthcoming pilot, and has published the responses to a questionnaire given to six potential operators. Nearby Richmond is also planning on trialing dockless “by April”. Redbridge is bringing Ofo and Urbo in on 2 March. This will give Urbo a contiguous … Continue reading Bikeshare in London – Borough Update →

The GLA published an interesting report last week: Future transport – How is London responding to technological innovation. It focused mainly on drones, driverless cars and app-based services (as an example, CityMapper’s experimenting on turning its huge desire-line dataset, created from the data of its millions of users and their journeys, into a group-based taxishare … Continue reading Future Transport Report and Dockless in London →

It looks like Brent will be the next London borough to get dockless bikeshare, with Mobike likely to be setting up in the borough within the next few weeks. The operator is not confirmed, although strongly hinted at, including by the council themselves. The choice of Mobike makes sense, as the operator already has a … Continue reading Dockless Continues to Expand – Here’s the Data →

The ORR publishes station entry/exit numbers on an annual basis, on a “best guess” basis, using ticket sales, gate information and modelling. The data is split by ticket type – full fare, reduced fare (off-peak tickets, tickets bought with railcards, advance tickets, child tickets etc) and season tickets. They make this data available as an … Continue reading Railway Station Numbers →

Following Ofo’s recent expansion to Islington and the City of London, Mobike has today also expanded to Islington and the City – here’s a set of operator-placed bikes outside Cally Road tube station: This presumably means that you can now cycle from Acton in Ealing, the original London location for Mobike, to Islington, for 50p/half … Continue reading Three Bikeshare Systems now Competing Directly in London →

My latest London data visualisation crunches an interesting dataset from the Department of Transport. The data is available across England, although I’ve chosen London in particular because of its more interesting (i.e. not just car dominated) traffic mix. I’ve also focused on just the data for 8am to 9am, to examine the height of the … Continue reading Evolution of London’s Rush Hour Traffic Mix →

There was a time when Google Maps was an ugly ducking. It started life as a road map, and its grey background was decryed at a memorable keynote at the British Cartographic Society annual conference 8 years, contrasting with the classic Ordnance Survey Landranger maps where the spaces between roads were normally full of “something” … Continue reading Putting Cartography Back on the Map – Google Maps Getting Prettier →

The ONS publish small-area population estimates annually, for England and Wales, and the NRS similarly do for Scotland. By taking two of these datasets, we can see how the population of Great Britain is changing – births, deaths, internal and international migration and military deployments/homecomings all act to fluctuate the population. I’ve taken the 2011 … Continue reading Population Change in Great Britain 2011-14 →
