Im using REALISTIC TRIPS mod, and it made much better the traffic, but impacts a lot on performance, even worse than pre-Economy 2.0, so you get to be careful
Yeah, I started using Realistic Trips in my new city the other day and that + Realistic Parking is making things very interesting. Especially now that we have the routing tool view in vanilla we can see where everyone is going. I also build a lot of parking... if you want them to use a car, they need somewhere to park... (both at home and at work(!) and I make it free of charge because I want as much incentive to own a car as possible.
Your goal is to provide enough parking for every building so everyone can drive there if they want. So, if a factory has 80 workers, make sure to have enough parking for at least 60-80 and watch them fill up and enjoy. I so love to see a sea of cars near the places the cims are currently at wherever that may be. If you build things "right" you can certainly get some car/delivery traffic going in this game.
For example, I have two residential buildings, they both together have 240 households. I've put enough parking around those buildings so they can accommodate 190 cars (parking lots & the new road parking roads) and usually those parking spots are about 95% full during night (see above mentioned mods).
When a new day arrives, they all head out to work, school, etc and empty out the parking lots so they are 90% empty and I can see where all those cars go. They go to local workplaces, shopping, leisure, school and some leave my city to go work there etc.
It's working fine. Now, I just started experimenting with a new city, so only around 5k population, but so far so good. I'm loving the lunch hour rush as well. I only have like 4-5 commercial building in the whole city just to see what happens and they get busy! That's for sure; hordes of people go there, and I can see the goods they hold dwindle down fast as people enter the buildings and buy things and I see delivery van's spawn all the time to refill the depleted stores.
Interesting enough if I have more customers in a store then there are gods (they ran out while everyone is there) all the cims exit the store and stampede to another commercial location that has goods. By car (if they had one) or walk etc.
I'm enjoying those two mods a lot, so far! We'll see what happens when my city grows. Either way, with those two mods and the latest Detailer's patch I'm enjoying SC2 a lot. Let's hope they keep bug fixing etc. and we'll get there eventually and then wallets will open.
