Can I change the setting after I have created the save?

Just like: pay for total distance
I don't want there are negative income on my buses.

You can, follow the instruction in the other thread. (This works not on online games or locked games.)

However, your income is positive; just the cost of driving makes in negative. Use slower buses and waiting times will help more.

No, I do not mean total income, but after my buses arrive the station, it actually earns an negative amount of money and reduces my income.
