So i added a passenger and car ferry, then added a bus stop in front of it. Everything is normal, all peds took the bus, road getting congested, income from mass transit getting doubled as you can see here
But then, since the road getting congested, i replaced the bus stop with subway. the subway has the same amount of usage as the bus stop, but the income from mass transit didn't get increased. And looks like the problem is from the ferry, it only has few hundreds usage.
Don't know what to do now, whats your guys opinion? currently on El Capitan and using NAM 36
