London Bike Hire Journeys – 29th April 2011

The most recent MRes Processing assignment was to show the flow of journeys from a day of London bike hire usage. My previous Processing visualisations have all been quite dynamic, the kind that run through data on their own. For this one I decided to take a different approach. It’s an interactive visualisation where the user can click on any of the bike hire stand locations to see where the journeys went to from that stand.

The when the app starts it looks like this

London Bike Hire Flows 1

The size of the stand locations shows the number of journeys from that location. Clicking on a stand then shows which other stands those journeys went to

London Bike Hire Flows 2

The brightness of the line indicates the number of flows from the clicked stand to the stand the line goes to.

Some of the stands didn’t have any journeys made from them – I assume that the stand existed but wasn’t fully open on the day the data is taken from.

If the user prefers to have more of an idea where the stand locations are, pressing space will display a map background instead of the more basic one

Overall I’m really pleased with how it has turned out. I think it’s quite useful for seeing the journeys made from each of the hire stands, and I like the way it looks.

Here’s a video showing the app in use

The UCL Hand-drawn Map of London

This is about two months late, but better late than never surely.

At the end of November I spent a week hanging around various places on the UCL campus with Alistair Leak (@Alistair_Leak / cartopedia.co.uk), and by the end of that week we had a collaborative hand-drawn map of London.

We started with a canvas that we had traced the outline of Greater London, the Thames, the Lee and a few of the larger parks on, to give people something to relate to. We then spent about 15 hours over the course of the week inviting passers-by to add something to the map. This could be anything we said – something famous, their favourite place, where they live, anything. The map ended up with all those things and more, including many pointers towards other countries where international students and tourists had come from.

One of the things I really enjoyed about was seeing where people placed things. There were those who were very confident, and got things very wrong, and then those who spent so long thinking about it just to make sure they got it right. And then what happens when one person gets something wrong? In the case of Hackney Empire people then, understandably, added things in relation to that. And a new Hackney appeared, about 5 miles away from the old one. (You can see the, traced, River Lee just to the west of it.)

In the case of UCL we ended up with two of them.

I also learnt things I didn’t know about London, like Lewisham being known as the blue borough. It’s because all the bins are blue.

We’d love to do another version of the map and have been given many suggestions including at the main train stations of London or in other cities. Both are ideas we’ve thought about doing, if anyone else is interested in this please do get in touch.
