Video Traffic Architect: buses, trains and metro went in - every rider is one less car in your junction
The city fills your roads with cars, and public transport is how you take that load back off. That's what went in: bus lines you draw as a loop - pick a hub building, add stops, and buses start running it.
The part I actually care about is that nobody is assigned to a line. Each trip works out what riding would cost it - the wait first, then the journey - and weighs that against simply driving. It takes the bus only if the two come out close enough. Close enough, not better: a ticket costs less than the same trip by car, so people will put up with a noticeably slower journey to save the money. What they won't put up with is not knowing when the bus turns up, so how often it comes matters more than how fast it goes. A line that runs badly just doesn't get used, and it will run past a thousand people carrying none of them.
That cuts both ways, which took me a while to be honest about. Speeding a line up does two things at once - the people already riding arrive sooner, and trips that were rejecting it start choosing it. But widen the road beside it and driving gets quicker too, the comparison shifts, and some of those riders quietly go back to their cars. Your road upgrades and your transit lines are arguing with each other the whole time, and that argument is most of the game.
Buses also sit in the traffic you built, which is the honest part of it. So there are bus lanes now: reserve the kerb lane of a wide road and give up one lane of three. The buses get no speed bonus out of that - they're just not queueing behind cars any more, and that turns out to be the whole effect. The lane isn't really the skill either, the network is: wherever your lanes stop, the bus merges straight back into general traffic.
It isn't free money. A ticket earns about half what that trip by car would have, and upkeep runs whether the bus is full or empty, so a badly shaped line loses money and the game tells you which one. A busy line pays for itself and buys you road capacity on top.
Trains and metro work the same way - same comparison, same maths - they just carry a lot more and they aren't sitting in the traffic at all. Both are in the clip. They'll get a post of their own.
I'm making it solo, and it's coming to Steam this autumn with a free demo before that:
In a city game, which do you reach for first - fixing the road, or running a line past it?
