124.1 r11272 pak64; overbuilt city streets keep their 50km/h speed limit

[FLN]

Former city streets keep their old speed limit of 50km/h after being overbuilt with an higher speed road type.
Overbuilding it twice, while also changing the road type again, will rectify this issue.

Is this behavior intentional? May it be some kind of result of this 2017 patch discussion?

To me it's not a biiig issue, probably it is not even a bug (if intentional), but it's just an odd, unexpected behavior and i wonder if it is an attempt to enforce lower speeds in urban areas or something similar...

it is

Ok    Thank you!

It's been a mild annoyance to me for many years, but an intentional design feature. lol

Well, I think it's a Royal PITA! Just because some Simumorons build their hovels next to a highway shouldn't mean that the local authorities downgrade the legal speed just to suit them.

Wellcome to Germany, and building near a road with a hamlet has a mandatory speed limit. There is a sign announcing the name of a town and it comes with 50km/h speed limit.

Be happy, we do not enforce the historical speed limit in Britain until 1904 in the game (4 km/h inside and 8km/h outside towns).

Sorry, I just realized that I am taking about a slightly different thing - when the town population expands my carefully placed rural roads get clobbered.
IMO, in this situation, the game should not build new buildings next to existing high speed ways.

... [EDIT] unless there is absolutely no where else that the building can be built and no other directions in which the town limits could expand.

[Oldie]

In this example Singlet has grown in an easterly direction and clobbered the existing highways (circled) when there is plenty of unused land both south and north of the town. Why? Is this accidental or a "deliberate attempt by the town to destroy infrastrucure"?

You are free to tweak the city building rules. But usually, new houses pop up next to roads and these roads were already within the city limit. There are fences for highways to prevent exactly this (or you could use tracks on either side for the same purpose).

To prevent this, you should build a dirt road to the left and right of the motorway.
In reality, Highways are also accompanied by access roads.

Cities grow along roads.

Aww yeah, the good ol' days! When automobiles where a rarity, didn't have anything, that we today would classify as breaks and scared to death the then ubiquitous horses, with the cracking and popping noises they made. Marvelous!

Did you know that back in 1900's London a pedestrian had to walk in front of every automobile as to pace their speed to this walking pace? Also anyone might be interested in taking a look at the Motor Car Act of 1903.
Enjoy, lol!

Where are this fences to be found?
I only know of this addons, "gauthier" our French fellow Simutrans player and forum moderator posted.
And once i used a nice green fence, I found on the the huge Japanese Simutrans community addon collection

a dirt road to the left and right of the motorway.

Note that some paks have fences available, which were added for, among other possible uses, this exact case.

I always use fences around my highways and freeways that require higher speeds. Which unfortunately does mean 3-4 tiles wide for roads that require such things.

People had bicycles back then, typically cruising at 15-20 km/h on level roads. Of course, horses don't care much about cyclists. We meet each other all the time in the more touristy places in the Netherlands.

Exactly what happens in real life: towns grow, speed limits are reduced where the road gets in the town.

In the modern day, we (or at least the Dutch government) make a distinction between 3 classes of roads, 1st, 2nd and 3rd. Each class has its own guidelines; only 2nd class can connect both to 1st and 3rd class.

	Speed (km/h)	Limited access?	Access to property?
1st rural	100-130	fast only	no
1st urban	80-100	fast only	no
2nd rural	80	sometimes 🚜, no 🚲	no
2nd urban	50-70	no 🚲	no
3rd rural	60-80	full access	yes
3rd urban	30-50	full access	yes

These are just guidelines, not rules. Municipalities interpret them differently. If the speed limit changes without any obvious reason, it's because you cross a municipal border. When a town expands, roads that turn urban don't change class, except during major reconstruction.

In reality, Highways are also accompanied by access roads.

Or there's a single row of city buildings along the motorway, then a city road, with the city road providing access to the city buildings.

Which unfortunately does mean 3-4 tiles wide for roads that require such things.

There's some fairness in that. Your typical motorway is 40 metres wide (including soft shoulders), I know one example 100 metres wide. Your typical double track railway is 15 metres wide. It's fair when the Simutrans motorway ends up much wider than a railway.
