The Network Addon Mod, or NAM, is a modification for SimCity 4 Deluxe (or SimCity 4 with the Rush Hour Expansion pack), which adds a myriad of new transport network items, ranging from ground light rail, to fractional-angle roads, to roundabouts, and much more. It also includes bugfixes to Maxis items and a highly optimized set of traffic simulator plugins, improving pathfinding accuracy and performance.
The RealHighway Mod (RHW) has been a very visible and actively-developed part of the NAM ecosystem for over 15 years, under the auspices of NAM Team lead developer Tarkus. The RHW has provided users the ability to construct a dizzyingly complex highway systems--including those by popular SC4 YouTuber Haljackey. However, its widest network has topped out at 10 lanes (5 per direction) since 2009, when RHW Version 3.0 debuted as part of the NAM 24 release cycle. NAM 47 finally ups this limit, with addition of the long-awaited RHW-12S network, featuring 12 lanes (6 per direction), at ground level and two levels of elevation (Level 1/7.5 meters, and Level 2/15 meters).
Not only does this new feature provide wider highways, but it also brings with it the prospect of wider ramps. NAM 47 also marks the debut of two new types of ramp interfaces, Type A3 and Type D3, which add support for higher-capacity 3-lane ramps to branch off three of the widest highways in the RHW: the RHW-8S, RHW-10S, and the new RHW-12S. NAM Team member Ulisse Wolf's first "secret weapon" video for NAM 47 showcases all the features of these new wider highways and ramps:
On the complete opposite side of the spectrum, NAM 47 brings substantial new gameplay options for active transportation to the table. The NAM has included the Pedestrian Malls feature--PedMalls, for short--since NAM 6 was released, way back in July 2004, which provide the ability to build completely pedestrianized streets. However, aside from some minor additions in the early days, and the vastly improved ability to connect PedMalls to the sidewalks along one's surface streets in NAM 33, and the more recent addition of the Midblock Crossings in NAM 45, the pedestrian side of the NAM's transportation toolkit has not seen much development until recently. This was in part due to the game's long-running (and hardcoded) issues with being able to properly support RCI (Residential, Commercial, Industrial) zoning along completely pedestrian-based networks.
However, thanks to the efforts of Pedestrian Revolution Mod developers Lucario Boricua and Ulisse Wolf, this restriction has finally been lifted. NAM 47 marks the debut of the Draggable Classic PedMalls feature, which features 8 different styles of PedMalls, all getting arond the game's hardcoded limitations and providing proper pedestrianized RCI zone access--even for Residential zones. Ulisse Wolf's second "secret weapon" video for NAM 47 showcases this groundbreaking development.
As these development show, the NAM Team remains committed to providing a wide range of new options for SimCity 4 transportation, whether you want to add "one more lane, bro", seek to build the ultimate walkable city--or perhaps even both. In addition, the NAM Team has also added a number of other features and fixes for the game's transportation system. Here's the complete feature list from the NAM 47 release notes:

Additionally, for those seeking a lighter, more minimal NAM experience, the new NAM Lite package has been upgraded to Version 3, featuring a number of fixes over its predecessor, and also adding support for FLEX Road Overpasses, which allow users to easily cross over railways and other surface streets with their Roads, One-Way Roads, and Avenues.
We hope you enjoy this latest offering of the Network Addon Mod--and stay tuned, as we continue to add even more functionality on all fronts.

Is it possible to use this mod with either the Steam or GOG version for the Steam Deck? And if so, how would one go about installing it specifically for the Steam Deck?
That's a very good question, and one where I don't really have a definitive answer, as you're the first Steam Deck user I've encountered. Apparently, it is possible to use non-Workshop mods with Steam Deck, but I'd have to know more about the file/folder architecture of a SimCity 4 installation on a Steam Deck in order to even guess at how to pull it off.
is there a mac version?
The current download for the NAM is cross-platform, meaning it's the same download for Windows, Mac, and Linux.
32bit can use?
Yes, but it requires installing the LowRAM/NoRHW option for the NAM Controller, and does not permit one to run the RealHighway (RHW) features, which require the greater access to RAM that a 64-bit OS and the 4GB Patch provides.
I downloaded the NAM 39 mod for Simcity 4 steam edition, but it won't show up on my game. I tried doing the roundabout feature to test it out and it doesn't work. How do I get the NAM to actually enter my gameplay?
PS: what's the best way to get a shorter commute time using the NAM?
Make sure you run the installer (NetworkAddonMod_Setup_Version39.jar for the current version). Simply dropping the contents of the download into your Plugins folder will not install the mod, and nothing will show up in game.
The big difference between the NAM's Traffic Simulator Plugins and the game's default is that it causes the traffic simulation to look for the route that takes the shortest amount of time, rather than merely the shortest distance. For instance, the game will recognize that the Avenue you built has a higher speed/capacity and actually allow it to be utilized, rather than clogging a Street simply because it's two tiles shorter.
What new methods of transportation did you add? (And also ambient vehicles, like maybe hot air balloons?)
Also, how can I add it to my game? Under which files do I put it? (I'm running SimCity rush hour on windows 7)
The list of additions to the game's transportation networks is probably too long to list. Note, however, we did not add any new transit types per se, and ambient vehicles are more something we leave up to third parties.
The mod has an installer, which, since it's Java-based, is a .jar file and not a .exe file, and will need the Java Runtime Environment (JRE) in order to run. Also make sure you patch the game to be Large Address Aware (LAA) using the enclosed 4gb_patch.exe file, as this is a big mod that requires more access to RAM (and without the patch, the game will crash). Simply putting the files in Plugins without running the installer will have no effect.
