City Infinity is a sustainable mobility design consultancy founded by Mark Philpotts (@rantyhighwayman.bsky.social).

We're collaborating with our clients and partners to deliver better streets and places across the UK.

Do take a look at what we're up to on our website.

A drawing of a crossroads junction with a pink two-way cycle track running left right across the top and crossing the north arm of the junction. In brown, pedestrian crossings over all 4 junction arms are provided. A photograph of a little section of street with a kerbed and planted rain garden between the footway (left) and road (right). There are three small timber cube seats with green, blue and yellow sides. Someone sits on the green cube. A plan of the northern side of Hammersmith Bridge with a "podway", cycle track and a pair of footways meet the street and interact using various little zebra crossings. A tactile model of a T-junction with a continuous treatment made from black foam board as a base, white foam board for footways and the continuous treatment and buff rectangles of sandpaper for tactile paving on each side of the continuous treatment where people might encounter drivers crossing.

It's nice to get enquiries, but sorry "Rastari" we're not civil litigation experts for multinational chemical companies; we're not sure using a Gmail email address helps either!

However, we do know a bit about highway law and regulation which we're often drawing on for our work.

Last Friday evening, Mark spoke at CYCLEWight's AGM where he talked about network design in the rural context, along with some of the infrastructure changes needed to enable rural cycling and urban connections.

We're pleased to report on a project that Mark has been working on with Robert Weetman for Manchester City Council.

This post sets out some ideas that developed from this work and which will hopefully start to explain what "pedestrian-friendly" is, and how we can design better side road junctions.

For those who prefer the format of the original Ranty Highwayman blog, my work post on side road junction design is also there. It's the same piece of course!

which are essentially saying

"OK, you're choosing a standard design and you want some level of flow-focussed design; how far do you wish to go and who do you want to exclude?"

Equally, it can't be done in one go which is why your design shows people the direction of travel.

Hopefully is was a gentle enough critique!

We'll be writing posts about network design because as you know, it *is* challenging, but ultimately our approach is framed within the street conditions, design *and* traffic system.

It then asks awkward questions (maybe for councillors)

October Rides Month – Part 2. This time I cycle from Utrecht to Nieuwegein and Houten, showing clear contrasts in cycling quality between the three municipalities.
📹 New video and blog post now online:
October Rides Month – Part 2: From Utrecht to Nieuwegein and Houten
On this second Wednesday in October, it’s time for the second instalment of October Rides Month. This time, I cycle parts of two main cycle routes: one from Utrecht to Nieuwegein, and one from Utrecht to Houten. The ride was filmed in May 2025, starting around 16:15, so we can clearly see the beginning of the afternoon rush hour.

is going to be almost impossible to get designs to the pedestrian-friendly side of the line (and it is one junction).

But, as stand-alone junction, this is getting to the kind of thing we are talking about within standard design and so it is great to see an example like this.

It's not meant to be a criticism of what is on the ground there because that junction is so much better than most UK practice, but that main road needing traffic calming and a zebra crossing suggests it might be a bit busy?

Of course, if an individual project cannot include network design, then it

"The single most important behaviour, design or regulation for creating streets conducive to walking and cycling, was physical separation between the modes"

We've got a new study out, learning from a broad mixture of street users, planners and designers

www.sciencedirect.com/science/arti...
Highlights For marginalised street users mode separation is the key to human-scale movement. Streets conducive to walking and cycling have functional, safe and accessible design. Professionals must approach street design, regulation and user behaviour holistically. Combinations of influencing factors persuade people to either use or avoid a street. There are no easy fixes to the public realm that will work for all non-drivers.

We can be quite sure that too much traffic means they don't work, especially for the most vulnerable people.

Absolutely. And vice versa too.

It does hopefully mean that there's also an approach that allows difficult conversations with the public and councillors - "OK, you want a flow-focussed approach; who is on your list of people it's fine to exclude?"

It is also worth adding that pedestrian-friendly design also requires the widespread deployment of 20mph speed limits and the gradual design of streets to make them self-enforcing.

Not at all ;) Our view is that the network becomes a really important consideration.

Unless the planning and policy (political) side is addressed, the engineers cannot fully unleash their full design talents, but they can push standard design further.

But it is *also* true that a pedestrian-friendly layout cannot just be dropped into an existing situation without considering the network; there are subtly different jobs here which has made the whole investigation fascinating.

To some extent. We think they are one piece in the jigsaw, but best deployed through network design unless the conditions already support - there will be places where they can be deployed now.

On the flipside, LTNs are also key and if we don't touch the network, we'll always have standard designs.
