Road and Rail bug in NAM (2009)

[Tyro972 1]

I started using the recent NAM (April 2009) on my SC4 Deluxe version 1.1.638.0, and found that building railroads, elevated rails and monorails over roads effectivily cuts that road segment from the network. Automata will not drive over/under it, U-Dirve It mode ends when I try to pass over/under it, and most importantly this cuts actual access for the AI to its destinations. No-driveway icons appear if the rail passes over/on the only road to a desired destination.

I made sure this is a NAM issue by uninstalling it and building rails over and on roads without NAM, and the problem did not appear. I then re-installed NAM with different components deactivated (only diagonal roads and roundabouts active, automata and traffic set to standard; or only automata and traffic mods active and road add-ons disabled; and finally only core mod files active) but each time this issue appears.

Has anyone else encountered this? Is there a way to fix this (excluding NOT building rails over roads).

I've searched the forum and didn't see any reference to this type of problem, which means either no one has ever built a rail on or over all the roads leading to or from a certain destination (that is, there was always some road somewhere with no rail over it, allowing the AI to reach the destination while increasing commute time); OR that there's something unique in my installation of the game or something which causes problems.

I would suggest trying the latest NAM June 2009 and see if the problem still exists or has been fixed in the latest version

Make sure you select the same righhand/lefthand drive as you game in the options, when you install the NAM.

tungston, I dont understand. I dont check the lefthand drive when I install NAM and I never saw anything in-game that refered to lefthand\righthand requierments.

EDIT: I installed the June edition of NAM and this bug is still there. I installed only core NAM files to be safe, but no joy.

You got the answer. You were told to not check LHD when installing the NAM. This tells that it is related to left vs right hand driving. Your game is either right or left (we do not know), and the selection during NAM installation must be consistent.

If the problem remains, it means that you have an old LHD file (assuming your game is RHD) somewhere in your plugin folder. As test, install the NAM into an empty plugin folder. It will work. Then, search your original plugin folder for the culprit.

Yes, indeed I got my answer, though it took me a while to realize the European English version is a LHD version of the game. So I just checked LHD in the NAM installation and everything works fine.

Thanks for the help.

I'm not certain, but I seem to have the same problem with roads going under an elevated highway.

I have this same NAM problem in other cities of mine, but in the one I'm building right now (where I've avoided crossing roads and railroads), I've plotted residential and industrial zones on opposite sides of an elevated highway. The zones are connected by roads leading under the highway. They can also both be accessed from the highway itself.

But although I have huge industrial and residential demand, and both zones are almost full, with thousands of residents and jobs, nobody commutes across the highway, either by car, bus or train. I have residential districts emptying out because of unemployment and industries shutting down for "lack of demand".

I suspect this also is a NAM issue, but I'm not sure. Can anyone advise me?

Also, I have used a couple of NAM components in other cities. Will I have to demolish them before I take out the problematic NAM?

If you have a game that the direction of travel is in the lefthand lane, then when you install the NAM, you must choose the lefthand lane option.

Wizard of ID:  If you bought the game in the country that you live in, it is a game that has lefthand driving.

It has more to do with a programming error. For some reason, Sims don't use highways. Most likely, the entrance and exit ramps they use are too close.
