Gravity Core, Suppression Zone and Leapfrogging… the basics of spatial economics

Let’s continue with urban mathematics shall we? If you are fascinated with cities as I am it’s a path worth taking. This is the ‘WHY’. The deeper understanding of why the city behaves the way it does.

Let’s see what the model I have developed is actually teaching us. As a reminder, the model progresses up to “Nash equilibrium” for one product, with equal distribution of suppliers and customers. The model illustrates how a market failure was created, similarly to the model of the ice-cream vendors. In this article, I would like to show examples of the phenomena that the model produces.

Pedestrians, Robots and MaaS… oh my!

We hear many bold claims coming from tech companies these days, boasting about how safe their autonomous cars will be and how much they will save us from those dreadful traffic jams. So many PR statements and so little common sense. It’s not that I do not trust autonomous cars, computer manufacturers or robots, those will work just fine. It’s us humans that will screw the whole thing up.

The hard stuff

OK, here it is, the most complicated part of the book. I’ll try to explain this urban mathematics thing as clearly as I can, but I guess I’ll need to re-write it few times. This article would probably be tricky to follow but fortunately, there are pictures.

So, deep breath…

My goal here is to find the mathematical equivalent of (don’t panic) Nash equilibrium on a large scale with many players. Just as in the example of the ice cream vendors, I am looking for the easiest way to explain why businesses are clustered in the city, using the simplest possible algorithm.

Hmm, sounds reasonable so far. Are you with me? let’s go.

How did Waze increase traffic jams?

Is it possible that a technological solution to one specific transportation problem will result in another, different problem being created? How does Waze and other GPS tools contribute to traffic congestion and what does it say about the autonomous cars?

Pedestrians, Scooters and MaaS, oh my!

Well, I’ve just been registered as a speaker on MOVE “The world’s most important mobility event, where disruptive technology and innovation drive much needed change”, ExCeL London, 12-13 February 2019

I’ll have 20 min so if you plan to be around, look me up.

This was the “abstract” I’ve submitted …
