Actor Russell Crowe tweeted this out back in October while he was in Bangkok filming a movie:

It's a photo of the city's notoriously messy communication wires. As I understand it, many or most of these wires aren't even active. The telecom industry just has a very ad hoc approach to running new ones and there's also nobody responsible for removing any of the old ones.

In response to this tweet, the Prime Minster of Thailand, Prayut Chan-o-cha, has called for these utilities to be tidied up and put underground. No more mess! Who knows if it'll actually happen, but it's kind of cool to see what can be done with a single tweet.

I wish I could say that my tweets were also capable of inspiring such swift urban action.

Here is a recent research paper by Christopher Barrington-Leigh and Adam Millard-Ball that looks at the connectivity of local street networks across the world. They refer to this as "street-network sprawl" and they measure it using a Street-Network Disconnectedness index (SNDi).

This is important for many reasons. Compact street networks with shorter blocks and fewer dead ends are far more conducive to different forms of mobility, including transit. Street networks are also incredibly sticky. Once laid, they rarely change. And if they do, it's over very long periods of time.

The study period in the paper is 1975 to 2013. What they found is that in 90% of the 134 most populous countries in the world, the street network has become less connected since 1975. What this means is that we have been making it harder to service our communities with transit.

That said, there has been a reversal in "high income" countries, most notably in North America. If you take a look at the above graphs, you can see a fairly dramatic drop off, signalling a reduction in the construction of low-connectivity streets. Southeast Asia, on the other hand, is trending in the opposite direction. Note Bangkok in the upper righthand corner.

Many of you have probably visited or seen videos of the Maeklong Railway Market in Bangkok. (I've done the latter, not the former.) It is one of the largest seafood markets in Thailand and it is literally housed on the railway's tracks. Every time a train passes through, the entire market needs to be pulled up and relocated. Even the awnings that cover the market need to be collapsed. The videos I've seen have all been taken from grade. But the below video (via Vala Afshar on Twitter), showing the market in plan view (from what was likely a drone), is arguably even more impactful. There isn't a foot of wasted space.
