Interested in people, places and planet. Spending time improving cities, supporting nature and decarbonising transport using data and insights.

Sheeeeesh this is dope

[New paper] Studies using street view imagery have been confined to driveable roads. We leverage the rarely explored subset of SVI data, e.g. taken in parks and footpaths, to assess the quality of public open spaces. Congrats to Shuting on her 1st paper! https://t.co/cHJ8plenh7

trying to make sense of the bigness of the Elizabeth Line so obviously had to move it north and make some maps (using correct geodesic transformation to account for shifting it northwards, obvs)

@SheffieldSW_LS How can we help get involved?

[Chris Stewart @walkenomics]

Great to see more local leadership pushing for more sustainable ways to get around South Yorkshire.

@thomasforth I am quite hopeful the current focus is to help rebuild LAs internal capabilities, as shown by recent announcements of £32.9 million for capacity building. https://t.co/bdTRQtY9yH

I've been using the `erase_water()` feature in tigris (#rstats) and pygris (#python) a lot lately to make more realistic-looking maps in water-rich areas like St. Petersburg FL

To learn how to use this feature, register for a free workshop with @UMSSDAN: https://t.co/yvCrvGCOre

@CarlinoDustin Loving the choice to include cross-boundary data!

[Chris Stewart @walkenomics]

@MeganStreb @zoe_billingham @IPPRNorth Would love to work with both of you on this and see how many other transport planners and active travel specialists I work with could help.

[Chris Stewart @walkenomics]

@ElaineStead This is excellent. I have literally struggled for years to find enough trained economists that focus on sustainability, environment, net zero and green finance.

[Chris Stewart @walkenomics]

This will literally save days of effort.

Healthy habits can last a lifetime. I’ve spent the morning with children at @LapagePrimary school in Bradford to launch our new early years walking programme in partnership with @livingstreets 🚶

@ArundelsofN @robinlovelace some excellent ideas here for ATIP

@Microlambert @CarlinoDustin @TfL @felt @willnorman @CycleIslington @camdencyclists Makes you think. It wouldn't be hard to export as one giant hi-res image to load into @felt.

I must admit I tried doing something similar pre-Christmas by screen shooting pdf CAD files.

Not pretty but was great for design collaboration meetings.

[Chris Stewart @walkenomics]

@AndyDAgorne @adamtranter I have some wonderful news!

You can find this in the first unit of the Department for Transport modelling guidance. It says in plain English (straight after recommending variable demand models) that modes that ignore induced demand are inadequate.

@thomasforth @openstreetmap Not going to say anything other than, I have a hometown advantage. I am responsible for ten (or so) of these dots.

[Chris Stewart @walkenomics]

@bricycle Have you ever thought about rendering the model in Blender for animation. P.s. not recommending throwing anything in a blender!

@JohnT__ Have a look at some nice infrastructure in Rotherham, on the way towards Meadowhall/Magna
