No Road Connection in all residential buildings

[Angry_Bubble 52]

Guys, a city here is the following problem: every residential building that is ready is marked "no road connection" and in minutes she is abandoned. How to fix?

[rsc204 21,866]

Are the residential buildings you refer too being grown or being plopped? If you are using ploppable residential, then that is your problem, it simply doesn't work and will always abandon as the sims will have no working road connection to leave the building from.

Grow

A picture of the area might help.

 

If all the residential buildings have the no road zot there are too possible reasons (and they were not plopped as rsc204 stated)

 

1) They have no access to a road

2) They can't find a suitable route to a job.

 

I would trace out your roads and make sure they connect to commercial and industrial areas so the sims can find jobs.

If you have loaded extracheats select Drawpaths (right click) to check if paths are working properly.

Grow

If u can give us a pic it would help a lot.Im guessing maybe the problem is you zoned next to rhw?

I think the problem is with jobs

[A Nonny Moose 8,262]

You are probably correct.  One must build evenly. 

 

I always start with either I-A or C$ lots, then add enough R$ to fill the jobs available.  This works for me.  You  could also start with I-D followed by R$ then build (slowly) from there.  I am generally in profit by the end of Sim-year 2.  Don't forget the fixed ratio of the game of Sims:Jobs::2:1.

 

Perhaps you have zoned too many R lots for the jobs available.  Remember that there must be a road connection to the jobs (or rail for that matter) as the pathfinder will flag lots for which a job cannot be found with a No Job Zot (NJZ).  One thing you could do to check on this is to load the 'extra cheats dll' then use the drawpaths command to see the results from the pathfinder.  (Turn this off with hidepaths.)

No, this particular phenomena has nothing to do with the existence, or lack thereof, of jobs. If there are no jobs connected to the road system, no residentials will grow. As described, it has to do with how SimCity 4's engine puts things together.

 

SimCity 4 allocates a certain amount of CPU cycles connecting lots to the road system. This value decreases the more the game engine has to simply maintain what already exists. The larger the city in terms of number of lots, and the more lots the game has to connect, the worse the issue becomes.

 

Eventually, SC4 will get around to connecting these lots. Unfortunately, this can be well past the time the residential lots give up and abandon (3 months). There's not much you can do to prevent this, save perhaps zone less areas as to minimize the problems when things abandon. One would think the faster your processor is the less an issue this would be, but perhaps not. What I offer is based on a tremendous amount of observation, not an understanding of the game's code.

 

No, it's not logical that SC4 will allow residentials to grow when it may not actually get around to connecting them to the road system before they abandon. "It made sense at the time," surely.

The "game engine" doesn't really exist in the terms of a singe magic piece of code.  It is in at least three parts: the pathfinder which hunts for routes to jobs, the builder which builds on lots that have been designated to build, and the overall simulation of the city which plays with the variables such as the budget.  There is no telling without access to the source how many parts there actually are nor how they interrelate.

Interesting discussion

[DavidB_ 83]

In several of my cities I've had the same problem, including one I'm working on right now. I upgraded several roads to avenue or Tram-in-Avenue, which has led to several of my north-south corridors causing abandonment of my high-density residential zones ("no road connection") but only on one side of the road!

 

As far as I can see, there's no problem with jobs, it's only happening on a few avenues built directly on a neighbour connection. Have let the game run for a few in-game years, no change. If there's any chance of a solution or just advice, I'll be happy to put up some screenshots.

[rsc204 21,866]

Honestly I've never come across this, other than a breif moment whilst the game is thinking, it always works before any abandonment, perhaps you are misinterpretting what the game is trying to tell you, that sims of that wealth type have no jobs they can reach from that location? Yes I play on a fairly decent machine, but I also have some not so fast machines I use in testing, never once have I found a bug here with the game.

edit: - Thinking about it, have you properly installed the I-HT fix, without it this problem is bound to happen as R$$$ sims can't get jobs in I-HT which really messes with the simulation. -

TIA is a little finicky, are you sure the zones are facing the TIA? Usually you need to hold CTRL when zoning next to Avenue or this won't happen.

How can I build (rebuild) an operative (I can see the traffic) road/street/one way road connection to a lot/buliding in lot editor?
