I am "planning."
Exact placement and size of various districts subject to change of course, but that's the rough idea.
Airport is in; cargo hub (rail and sea) at the top on the river is in, with rail that links to all three external connections; tourist port is in, with a small road to a nice bay-side hotel (tourist attraction) that overlooks the bay bridge.
Cargo hub will link to a smaller cargo rail station (or two) somewhere near downtown to try and avoid too much cross traffic, and hopefully if my road skills are up to it there will be a ring road to get goods where they need to be. Top 'villages' residential will feed the industrial area with workers hopefully, and no goods vehicles will be allowed in. There might be a secondary touristy commercial area in the south, to the right of the lower 'villages' area. 'Downtown' and 'offices' will likely flip to be horizontal rather than vertical as I have represented them here, so offices are in the north along the highway, and downtown is in the south with the prime coastal real estate.
I'm going to attempt more internal rail connections this time, but will likely lean heavily on metro systems since they're the simplest to deal with. Buses freak me out, I can never work out where they are best used - probably a loop or direct service to get people from one side of a district to another, rather than to go between districts? I'm not sure what the deal with the new taxi ranks is, I guess within the downtown area to let tourists visit different attractions? I like that when you put in bike lanes you see a considerable increase in bike traffic. I wish there were roads that still had nice greenery as well as the bike lanes (I have that extended network connections thing with extra roads but there aren't any included in that).
I wonder, if I extended that larger island out in the sea would it push a load of water inland or will it disperse into the sea? I'd love to have one or two nice tourist attractions on there and have it as a little island retreat. I generally don't like using the terraforming tools anywhere near water because the knock-on effects are usually disastrous, but maybe it's not as bad out in the ocean?
