I have an older city which runs pretty well. They all use public transport and let their cars at home. I should raise the transport fee (every transport line set to zero right now) and see what happens.
But I'm very satisfied with the sim speed for now. My city has 475k pop and sim speed is about 2x...2.5x
 
In my opinion, improving performance means increasing boredom with simulation cuts. I prefer a vibrant town to a city with performance but no life. I've set the Realistic Travel mods and Traffic Simulation Adjuster to 0. Now I have a more realistic city, with its traffic jams and challenges.

Realistic Trips is a necessary mod imho, it makes the game so much better and immersive.

I've noticed the same thing after patch 1.2, but I also felt like with every patch I have less and less traffic in my city.
So I have city with 280k population and I know for sure about multiple bottlenecks mainly on highway exists to city center and they were bothering me all the time before. Now I don't have any traffic problems at all. Some people said that it's because of good public transportation so I decided to do a test. I've used Sim Census mod to see how many cars were active before I removed all public transportation lines and after and I was shocked but those numbers. I let it run for some time after I removed it.

I had ~240 personal cars active before and approximately ~800 after. Those numbers are just hilarious for a city that big. Can you imagine having 244 personal cars in a city of 280k pop? This is absolutely ruined my experience with the game. So much for 'pathfinding optimisations' in the last patch.
So, I posted earlier about having very little traffic. I've checked again after some time has passed in my city since the anniversary patch 1.2.5, and it's much better now. I have around 2,000 personal vehicles and about 4,000 in total, which is a significant improvement. And those numbers are with existing public transport network.
Overall, my city no longer feels deserted—I actually have traffic jams now!

Moreover, performance now is much better. I don't know what they did and how, but it's a game changer for me.

For my part, I also confirm a clear improvement in my new city now 350,000 inhabitants, since patch 1.2.5.
The roads and motorways are once again lively, which finally revives the challenge of traffic jams and life.
But why do we have to wait for a patch to hear back?
Why didn't a moderator simply report that the problem had been reported?
There, yes no problem, a little communication much appreciated

And every police car is on patrol! I already had to rebuild 3 quick fix interchanges due to bottleneck, so if you wanted traffic I say it’s back above 40% sometimes as high as 60% of a bustle. I will give the economy a year and homeless a few more months to shuffle.

I just cleared all cims and parked cars then removed obsolete to ensure the patch and traffic starts from scratch. Anyone with an existing but small city try this (dev mode simulation tab)?

I did the same with a city of 300k (dunno where that lands for you as big or small) and it's been running great. More traffic than I used to see which is neat. I'm actually struggling with parking as all my cims seem to prefer to own and use cars. Public transport network gets decent usage but still seems under-utilized even when setting ticket prices to 0 and parking prices are sky high.

Newest problem is that job levels seem to have stagnated even as I zone more. I've seen other folks say the dreaded 5-worker office bug is back -- haven't had a chance to reconnoiter yet but will next time I play.

Hmm, not sure - in my city it seems reasonable. Don't forget that the price should not be the only factor in C:S2 compared to C:S1 (in which case it was even more just distance). Contributing factors of the usage of transportation services are:

- speed (for which also complexity is taken into account - stop signs, traffic lights and congestion are factors)
- comfort (relies on the citizens age mainly - seniors are looking for more comfortable means of transport, so rather often cars win, teens look for cheap solutions and don't care much about comfort, so your free bus wins)
- price (obviously depending on the wealth level)

So it's a bit hard to tell if something is right or wrong, however my freshly build tram line seems to be quite successful (rush hour is just over) ;)

Ah, gotcha. You and I have different ideas of successful -- I see similar utilization for trams in my city but it's lower than the numbers I was seeing before their December patch a few months ago, so that's the baseline I'm using. Buses seem to get even heavier weighting. Would like to see higher percentages for trains and ships. Haven't bothered with an airport yet since when I've built one in the past, the usage rates are always exceedingly low.*

*in my estimation, ofc

Trains are similar utilized as trams in my case, I mainly use them for longer distances and to connect the city to the outside. Also I see a good utilization of aircraft (at peak hundreds of citizen queue at the gates). As on the map I play is not much of water I didn't bother with ships instead ;)

For ships and aircraft to be utilized realistically I think a fair amount tourists are still missing, not necessarily ones traveling into your city but ones going through your hubs, traveling from one destination to another and switching public transport options. That would also provide some good income.

I _think_ you see public transport less utilized because since the last patch in general more vehicles spawn, so also more cars - at some point that number was either intentionally or not reduced which forced more citizen to use public transport it seems.
 
I noticed more traffic with one of the patches that limited the age of residents. I had more people moving into my city at different times of day because they died faster.

BUT my trams/bus usage went down alot. I find busses a feasible option now in my city of 250K. Before i needed trams and had to get rid of busses.

Yeah sadly what players of this game need is not tips from other players on how to navigate around (or worse, to blithely accept) broken systems, but rather for the devs to fix the broken systems. If you're only getting hundreds of cims to use air travel then it would again appear that you and I have different definitions of success. I have that many cims using air travel as well, it's just way too low for the size of city and the capacity of airports/planes.

I do agree with your second paragraph.

Ah that's interesting to hear, thanks for sharing. How much vehicles did you have before the patch?

And do you notice a rush hour again? In my city, the traffic flow graph did not have a spike in the morning and evening anymore.
 
I tested my previous archive again. With 310000 people and an astonishing 12000 active vehicles, there are lively traffic jams everywhere, with simulated speeds fluctuating around 0.21. However, after a period of simulation, the vehicles quickly dropped to 4100, and the simulated speed naturally increased to around 0.81-0.87 fluctuations. It is obvious that CO did not cause the game's vehicles to return to their previous state.

Thanks! But do you notice a difference compared to pre-patch?
