  1. Since Brian is showing us his plan for the development of the city he is currently starting to build, I'd like to show the current state of one of the cities in my cluster, where I am not pleased with my initial design decisions. The city is Desognes, it is situated in the upper left corner of the cluster. Here is how Desognes is currently zoned; R1 was the first residential zone to be developed; fairly soon during the growth of the city I started the zoning of R2, the second residential zone, on the other side of the river, Similarily, I1 was the first industrial zone to be grown. As I didn't want it to become too large, and because I was still asked by the game to zone for more industry, I started the zoning of I2; I2 has remained rather modest in size, and at present I do not zone for more industry. C1 was the first commercial zone; i decided to place to the right (i.e. on the eastern side) of the citly tile. This was done because Desognes has links (highway and rail) with Marlande which is contiguous to Desognes on the eastern side. C2 is a very recent development, still modest in size, that will not be able to grow much, because of the terrain available. In retrospect,, C1 is too off-centered, relatively to the R areas, especially relatively to R2; Sims travelling from R2 to C1 must pass thru R1, and this generates an excess of thru traffic in R1. It is in order to alleviate this to some extent, that I decided, belatedly, to start the second commercial zone C2, closer to R2. All morning commute traffic to C1 comes from the west and the north, this tends to saturate the roadways and the public transportation (GLR/subway, local rail and buses). With these design flaws, the city has currently a population of 742'351 Sims. However, its growth has slowed down, and the traffic issues are getting worse. I'll continue to work on it of course, trying to compensate for the noted defects. This is in fact an interesting challenge, that is encountered in RL in many old cities (my home city of Geneva is a good example of that....). Some other cities in my cluster exhibit various other 'defects' and/or limitations due to the terrain, waterways, etc. I may document some of those later.
  2. This is, indeed, an interesting blueprint for the development of that rather linear city. I am curious about which method you use for land-filling the terrain that is under water. Do you go into god-mode for that?
  3. 'bben' pointed me today to your CJ. Congratulations for all your updates sofar! How many region tiles have you developed sofar? Keep up that good work!
  4. Here is another picture of the same train station, with the traffic query for it: When we add the figures for bus, train and 'elevated train' (which is in this case GLR) we get 112'435 - much less than the quarter million shown by the other query. But we would need to add the Sims on trains arriving from the bottom of the picture and passing thru the station, which are possibly not shown here. At an rate we can see that Sims arrive at the station from both directions, by GLR and by bus, and leave in the direction of Deramey and Cherenne; this is the morning commute. It is not easy to reconcile the figures. Also, queries on the rail tracks at the bottom of the picture show numbers, but no travel paths. It is possible that the traffic simulator has not yet completed its work since the upgrade of the train station. I'll keep watching that situation, while pondering the next upgrade steps.
  5. Upgrades attract traffic, it seems, and some parts of the rail system in the cluster are bursting at the seams. Here is an example, found in Arcens, the center city in the cluster. The rail station in the next picture got upgraded very recently. The statistics after a few months of gameplay are quite worrying: The pair of dual tracks going to the top of the picture link to the neighbor city of Deramey - quite exactly to the rail triangle that was recently upgraded in my recent CJ entries. The volume statistics on those pairs of tracks are also of great concern: On the left pair of tracks the volume is - unsurprisingly - 65535. This means that the link is saturated, which in turn explains the excessive usage rate of the train station. Aside from upgrading the station again, I could put in a third pair of tracks, but I find this rather unrealistic. Another option is to add one or more subway links. I am undecided at this point. What this tells me is that I am encountering more and more saturation issues in inter-city traffic, and it may put an premature end to my work with the cluster.
  6. The Rail Triangle Upgrade project in Deramey was finally brought to a satisfactory completion. It was not easy. Some citizens, supported by the Chamber of Commerce which complained about disrupting the commercial area next to the rail tracks triangle, proposed an underground solution, that got rejected mainly on account of the immense cost. Eventually a solution was proposed which was accepted by all parties concerned. Once the project was accepted, work proceeded swiftly and with a minimal amount of disruption. Only two commercial buildings needed to be demolished, and their owners were suitably compensated. Rail services had to be temporarily suspended and replaced by buses. The completed upgrade, with 3 commercial lots to be rebuilt, is shown in the following picture: The mayor inaugurated the new layout by riding on the first train using the upgraded rail triangle. Rail service resumed on the same day, with a new schedule featuring more trains.
  7. At first glance, relatively to both issues, it looks like the northern part of the highway is dimensioned too modestly, with simply a few MIS lanes. I think that this will require a solid expansion. Also, the link from the northern part of the highway with the CBD is underdimensioned. But of course, as we just discussed in chat, this was originally a test city, which wasn't meant to grow much. The fun of playing a city is to see it grow. Once all growth has ceased, it becomes sort of ho-hum. For me at least.
  8. The rail specialists at Deramey have asked for more time to refine their proposal; this request has been accepted, even when rail travellers have sent a petition with several thousands of signatures to request more capacity on the trains. ------------ Meanwhile, another issue has been noted, on the RHW-6S highway linking Marlande and Arcens: This is a congestion view taken in Marlande. Aside from the connecting tile on the side of the RHW-6S highway where the measurement is taken. the highway shows only a medium level of congestion. Has anyone else already seen more than 50'000 bus travelers on a highway? Can I claim a record here? In RL, standing passemgers are not allowed on buses running on highways (at least in most western European countries) . They must all be seated. A standard bus has a seating capacity of about 50, If we apply this rule in the game (and I am inclined to do so), this means that we need a bit over 1100 buses per day to carry the commuters coming from Arcens. That's a lot of buses, especially if it all has to happen during the morning commute.. In the other direction the stats show 9528 cars, 1216 buses and 148 trucks - nothing to worry about...
  9. Congratulations then, Brian, for both the quarter million milestone in The Isles, and your long-lived region, which will be 10 years old next year and we will have another occasion to celebrate!
  10. The first plans shown by the railway specialists to resolve the triangular junction issue in Deramey were turned back by both the city authorities because of the impacts on the area, and the TRC (Talaran Railway Company) because of the insufficient capacity. The engineers were asked to return to their desks and come up with something better. Meanwhile, there was expansion in other cities. The total population of the 9 cities has now reached the total of 5 600 224 Sims.
  11. I think that you still have a major point of congestion, about at the middle of the two previous pictures, where there is a single road crossing the main arteries coming from the highway and distributing the traffic into both sides of the CBD. At rush hours you have probably a massive traffic jam building up there. You may need more accesses to the CBD local road network, in order to distribute the traffic more evenly and avoid congestion.
  12. Thanks for your encouraging words! I didn't specifically plan to have such an amount of rail traffic in my cluster of cities, but I think that this is a result of my encouraging too much usage of public transit in the various cities, by providing a generous amount of bus, tram and subway connections, linked of course with the railway stations. Well, I am 'stuck', in a way, with that situation, and now I have to make the best of it and develop solutions to keep things moving. It is, needless to say, just the type of challenge that I wished to have to deal with when embarking on this cluster project. Returning to the rail triangle I was showing in my previous post: in order to get more information about the volumes on the various branches of dual tracks, I took measurements and summarized them in the following drawing: The city in which the rail triangle is located, is Deramey. The numbers are supplied by the volume query. As can be seen, the tracks on the right of the drawing connect with the neighbor city of Arcens; those at the bottom of the drawing connect with Cherenne. On the top of the drawing, the right pair of tracks lead to Deramey's main station (and further, to another local station in Deramey), The left pair of tracks branches, on the right to the main station, on the left to other local stations in Deramey. All track pairs show heavy usage. The exception is the 'little corner', the pair of tracks linking the left vertical tracks to the bottom horizontal tracks, where the volume is only 18970. The two dual tracks going to Arcens have a total volume of 52799 + 18970 + 50543 = 122312; this is still less than 2 times 65535, but the loads are not balanced between the two pairs of tracks. There is still some capacity on the left tracks going to Cherenne. As an immediate measure, the link shown as a dotted red line should be added, to help balancing the load between the dual tracks to Arcens, and make use of the reserve capacity on the left track to Cherenne. In order to keep with the current practices in RL, this cannot be implemented at surface level, because of the conflicts at the intersection of tracks. A flyover solution needs to be put in place. Due to the relatively cramped conditions of the area, this will be difficult to realize. The city authorities have already declared that tearing down the Congress Center and rebuilding it elsewhere is out of the question. The project is being tendered with the hope that several engineering firms will respond with solutions acceptable both financially and urbanistically.
  13. Here looms the next issue to address: saturation on a pair of rail tracks, in a situation where the trackage was already doubled to cater to the heavy usage of rail: The second pair of tracks, next to the one showing saturation, still has a bit of capacity, but not a lot (the number, which I forgot to record, is around 50'000). It will take me a while to figure out what to do in order to alleviate that situation.
  14. I agree: this is a nice update, Brian. I like your use of condos - something that I haven't considered at all sofar. I don't remember downloading any of these lots when I prepared for CAM. They do cram a lot of Sims on a small surface. Then you have to give work to these people - well, to about half of them, but still... I will be interested to watch your highway upgrade, from RHW-4 to, I guess, RHW-6, which will entail changing the at-grade crossings by overpasses, ramps, etc. I don't doubt that you will handle that upgrade in a masterful way..
  15. Brian, thanks for your advice, which allowed me to resolve that issue. I use the Ultra setting, so I searched for a file called NetworkAddonMod_Volume_Data_View_Z_Ultra.dat - and didn't find it in the main NAM folder! In fact, there was no Volume Data View file at all there, which explains why my volume view reverted to the old Maxis volume view, by default. It turns out that the file (which was of course present in my old NAM environment, prior to the upgrade) gets removed from the NAM folder during the Cleanitol phase of the upgrade. Why that file is being removed, I don't know. Maybe it is meant to be replaced by a 'newer' file (which would be the exact same file since the Traffic Simulator is stable since many years....), and that replacement isn't done. I moved back the file to the main NAM folder, and I get again the proper color scheme in the volume views.
