You're not doing anything wrong. With Simulator Z, traffic always slows down at heavily used intersections, simulating stop lights (at least to some extent) or stop signs. This is implemented by using the intersection effect, which has always existed in SC4, but not at levels that made any difference. Unfortunately, when it is used at meaningful levels, congestion results at the affected intersections. You can see this in the way congestion shows up around the intersections. Using the Ultra version of Simulator Z will definitely reduce this effect drastically, if not completely, due to the simulator's higher capacity. Although the TSCT has been discontinued, you can still select the usual simulator capacities in the installer. As for the traffic advisor, he doesn't know about the intersection effect, so you'll just have to ignore him.

I was a little surprised you recommended the 12600K instead of the 13600K, until I looked around a bit in the Canadian stores and couldn't find the 13600K. It's still a fairly new CPU, so that's probably why it's a bit hard to find. I thought that that was why you recommended the 12600K. I agree that the 13600K is the CPU to get if you can find it at a reasonable price. Windows 11 is necessary in order to take full advantage of the features of these CPUs. @Haljackey, the "K" at the end of its name means that the CPU is unlocked, which means you can overclock it. I've been overclocking my CPUs for decades; it's not hard, and it's completely safe if you follow the directions. Overclocking essentially gives you a speed boost for free, something that comes in handy while you're waiting for the NAM traffic simulator to run. If this interests you and you get the 12600K CPU, you'll need to get a motherboard with the Z690 chipset (such as the one I recommended), as that's the only series that supports overclocking. If you get the 13600K CPU, you can either get a Z690-based motherboard (which would require a simple BIOS update) or a Z790-based motherboard; either would work fine for you. As for a basic summary of the difference in Intel chipsets (i.e., Z-series vs. B-series vs. H-series), I'd recommend the Intel document How to Choose a Gaming Motherboard. This document also contains useful information about a variety of motherboard basics. I should have figured that if anyone had a bigger monitor setup than me, it would be you... An ultrawide monitor might be the perfect upgrade from your setup, especially since these go all the way up to 49". Many of these come in 1440p resolutions, but some of them also offer 5120 widths. This is twice the width of my monitor, so it's perfect for someone used to having two monitors. The common term for these monitors is "double QHD". Here are the command line arguments I use for my copy of SC4: -CustomResolution:enabled -r2560x1440x32 -f -Intro:off -CPUCount:1 -d:DirectX All of these options (except the -Intro:off) are necessary to get the display to work properly at 2560x1440. If your display doesn't work properly with these arguments, you probably need a better graphics card. This has always been true. The DatPacker program, available on the LEX, can eliminate the majority of these delays.

I think the most meaningful upgrade you can make that will enhance your whole SC4 experience is to get a 32" QHD (2560x1440) monitor. I've had my current one for five years, and there's no comparison to my old 24" monitor. SC4 will run at that resolution out of the box (it's the highest resolution that will work without a wrapper), and you just get to see a lot more real estate at a reasonable size, with no display lag. I'm partial to HP monitors, as I find they tend to offer the best price/performance, and you can get essentially the same monitor I have: HP 32-inch 165Hz QHD HDR at Amazon. At CA$441 it's not exactly a bargain, though; this same monitor has been on sale in the US recently for as low as $165. I'd recommend waiting for the upcoming sales. You can recoup a lot the cost of this monitor by cutting back on the video card in Shadow Assassin's recommendation, which is way overkill if you're just playing SC4. I got a Radeon RX 570 for a little over $100 a few years ago, and it drives my monitor flawlessly. Prices are higher today, but you can still get a ASUS Dual AMD Radeon RX 6500 XT OC Edition 4GB GDDR6 Gaming Graphics Card for $241; this is also a newer generation. The CPU that SA selects seems to be the best balance between affordability and power available right now, at least in Canada. The B660 chipset motherboards aren't really the best for gaming. Instead, I'd recommend the ASUS TUF Gaming Z690-Plus Wi-Fi D4 ATX LGA 1700 Motherboard at the same price. As for memory, you can get the excellent Corsair Vengeance RGB DDR5 32GB (2x16GB) 5200MHz C40 Intel Optimized Desktop Memory, which should be at least as good as G.Skills, and save over $100 in the process. The other items look reasonable to me, although with the exception of the SSD, I haven't looked into them in detail. If you add up all the changes I suggested, your total price should be about the same, plus you get the nifty 32" monitor in the deal.

Your version of SC4 is the latest and should be completely compatible with the NAM. Why you're having these problems is a mystery, but rest assured that the NAM Team is looking into this.

Some traffic congestion with the Low traffic simulator at these population levels is normal, and should not cause a problem. If you think there is too much congestion for your taste, try a higher capacity simulator. You have to reinstall the NAM to do this. When you install the NAM, you are given the choice of different capacity simulators. In order of increasing capacity, these are Classic, Low, Medium, High, and Ultra. The Low capacity simulator is recommended for most people. Generally, cities don't need additional parking, as there is implied parking at all commercial and industrial buildings. Adding parking to a city will generally have no effect in the way that the city runs. RTMT is by far the most comprehensive solution here. You will need the base pack ROAD TOP MASS TRANSIT as well as the add-on pack RTMT Add-On Pack V3.60 . RTMT v4.0 should be coming out in the next few months; this contains a lot more stations, and it is considerably easier to install.

I notice that you're running the Classic capacity simulator. I would strongly recommend upgrading to Low. As an alternative, you could build up your subway network. Your usage and congestion are not at all unusual for your population level using the Classic simulator. I was able to create a city with 4.129 million Sims with this simulator. It worked fine, but everything was congested, even with a huge subway network.

The first post of this thread has been updated with more accurate values for the TSECs. The new values are within 4% of the old values, so it's not essential that current stations be updated, as the effect of the new values are minimal. However, if you are building new stations, please use the new values.

This is true only for stations that support large numbers of networks (typically more than three) passing through them. For other types of stations, the HSRP transit switches will either be excessive, will reduce the functionality of the station, or simply will not work properly. To find the correct TE switches for a given station, find the NAM station that most resembles it and copy the TE switches from the NAM station, adjusting them if necessary. Paying attention to the number of networks supported by the station is key, as is whether the station has networks passing through them or just adjacent to them. In the latter case, the BriPizza stations work as an excellent template. (Note: When I say "networks passing through them" (the TE lots), this is technically not correct, as networks don't pass through lots. But it appears as if they do, and this terminology is fairly intuitive.)

Before NAM 43, there had been no modifications to the traffic simulator for many years. The modifications to the traffic simulator in NAM 43 (which I gather was not where your problem occurred) were merely minor bug fixes. @gviper, the behavior you describe sounds like that of the old Maxis traffic simulator. The only way you would get such a simulator in your game would be if you accidentally deleted the NAM traffic simulator. In your Network Addon Mod folder, there should be a subfolder named "9 Traffic Simulator", and this subfolder should contain the traffic simulator and the traffic data volume view. If it doesn't, please try reinstalling the NAM, and then checking that folder again.

@The Angry Convert The log file is very useful; it is telling you that the TSCT can't find your traffic simulator files. You are indeed running an older version of the NAM, and it appears that that is what is causing your problem. If you look in the main Traffic Simulator Configuration Tool folder, you will find a subfolder named "data". Inside this subfolder is a file named "TSCT.conf". You need to edit this file. Depending on which version of the TSCT you have, there will be a couple of lines that reads something like: # pathTS is the path to the TrafficSimulator pathTS=C:\Users\Name\Documents\SimCity 4\Plugins\Network Addon Mod\9 Traffic Simulator You need to replace the part of the line following the "pathTS=" portion with the actual path to the folder containing your traffic simulator. In your case, this path would end in the string "Dokument\SimCity 4\Plugins\Network Addon Mod". Once you do this, save the file, and everything should work.

Yes. You need to have the NAM installed, and then you need to use one of the Subway to Underground Rail Connector (SURC) pieces that exist at the bottom of the Misc Transit menu.

I found out why I couldn't fix my prop pox. This particular city also suffered from two versions of the phantom slider bug - one in which the sliders of all the police stations would gradually drop to zero (along with their coverage), and one in which the health facilities didn't have their individual sliders drop, but the global slider dropped over time. This led to complaints that my health facilities were underfunded, even though the individual facilities had sufficient funding and coverage. As the way I got to this situation was a bit different from the standard way of generating phantom slider problems, I had to generate my own solution, which was actually a bit simpler than most solutions for dealing with these problems. Once the phantom slider problems were fixed, the standard fix for the prop pox worked, and the city has been running completely healthy for many decades now. From my experience, both here and in one other case, it appears that the phantom sliders can affect the prop pox. In cities where both problems are present, fixing the phantom sliders first and then the prop pox should end up fixing both problems permanently.

I guess that's me... 1. z 2. Male 3. Pisces I'm adding a BMP-formatted square icon just in case that works better than what you've got. z.bmp
