What Transit-Threads is for

Transit-Threads is the name I gave this blog because transportation is never one thing. A bus route is a thread. So is a rail corridor, a household travel diary, a flood on the State Railway, a land-use coefficient that only holds in the morning peak. Pull one and you find it stitched to housing, climate, party policy, and whoever owns the station.

I write from two cities. Bangkok is where I learned to count trips and argue about buses. Tokyo is where I now try to generate them. The blog sits between those places: not a lab notebook, and not a consultancy memo. Papers, slides, and the CV live on the research one-pager. Here I want room for the connecting tissue — what I actually think after the abstract.

What you will find

• Cities, mostly Bangkok, sometimes Tokyo, occasionally a Thai region that the national models forget.
• Models, from four-step sequential demand through geographically weighted regression to agent-based trucks and, now, generative mobility.
• Infrastructure that fails in the wet and the heat — railway floodplains, buckling rails — because climate is not a sidebar to transport in Thailand.
• Opinion, when a policy idea is fashionable and the implementation path is not.

I will not recap every paper. If you want the GWR on the MRT Blue Line, the flood-risk orals, or the buckling work, start at publications. If you want the thread that ties them together, stay here.

A note on tone

“Simple-minded” on the blog masthead is deliberate. Transport writing is full of frameworks that survive contact with no city. I would rather be clear and wrong in a way you can argue with. Comments are welcome; email is better if you want to actually change my mind.

The next posts are a map of the research, and an argument about privatization: if a government is going to sell the railway, it should look like JR, not like a franchise painted on rotting track.
