Heavy Traffic Congestion.... Help!

[ivanwong1989 0]

Hi,

 

 

 

 

 

 

In this city, I plopped down full streetcars and buses. Streetcar usage stands at 11k with waiting times of 25minutes. Bus usage stands at a meagre 3k with waiting times of 56minutes... Why isn't it working?

 

 

Any ideas or comments?

You have too many interjections! Eliminate some and the traffic flows better. You can use tunnels (if possible) or bridges to create over-/bypasses. Hope it helps.

how come this kind of city has too many intersections?!?! lol

i know what you mean, but seriously, how many is too many? 3?

this game is weird sometimes.

 

though you're right: building tunnel directly connecting ind and res should relief traffic problems...

 

but also, don't bother about wainting time on streetcars and buses: there's never enough wagons and buses for a 100k city. You can plop 3 streetcars garages and still you'll get long waiting times.

Yep, streetcar and bus capacity is quite limited. Here is my city of 650,000 ("Actual" population mod installed)

So even with a very extensive mass transit system, only 20,000 of 75,000 will use it. (The streetcar usage varies between 2 and 20k on a day to day basis, quite odd, but bus usage will take an almost 1:1 hit, so usage overall on mass transit 17,500-25,000)

 

 

 

Now for your road design, here is my input:

Actually, the original road intersections does not have that many dirt roads connecting between avenues. I plopped them down to ease some traffic, but no use.

I thought waiting times is related to how many will be using the transit system?

Now for your road design, here is my input:

 

 

The city started of in the left hand corner (yellow circle). In there exists some residential and also commercial mixed together.. Generally traffic is quite fluid there....

Then the city expanded in radial direction to the right. To 2 avenues of residential and services, followed by one avenue of commercial(the middle 4 way intersection), then one avenue of industrial mixed with residential.

So is it because of the basic design itself? of is it because i clustered commercials on one avenue? As I understand from your post, you said that zones on avenues are not good?(I thought to have the highest density buildings, one have to zone it on avenues?)

Ah, ok. Well, (unless I'm totally mistaken) it looks like there are a few more commercial buildings there than there "should" be. When planning my city above, I just zoned one large park worth of space commercial per "block" which I'm defining as "area surrounded by roads". In reality my blocks are kinda big, so I needed to add more to areas that abandoned due to lack of parks/shops. This reduces traffic a bit. 

 

I see how it expanded and its pretty neat. However, yes, you should not zone on avenues. There are only 3 density types (Low/Med/High).

 

High Density Road, High Density Avenue, High Density Streetcar avenue -- All "high"

Medium density road/avenue -- "medium"

Dirt/Low density road -- "low"

 

A cluster of commercial isnt a terrible thing if its done fluidly. I dont know how good the shopper AI is, but if they dont avoid driving to a shop that is out of goods, then small clusters should perform better than non-calculated randomly zoned commercial. I dont know if they do that or not though.

 

I'm gonna guess the biggest design flaw in the city is the avenues being zoned on.

 

But im not an expert!

You are completely right, you should never zone on your avenues except it is planned. Avenues are the veines of your city. Keep them free of traffic. Feed them with normal streets and leave space between interjections to have "buffer" zones for traffic. Short streets tend to jam fast!
