Topic: New factory and attraction disturbs player highways

[Ranran]

Hello.
I witnessed the road restrictions being rewritten when a factory was opened by chance. (´・ω・｀)
I think this is undesirable behavior.



As the factory connected the road, one-way was rewritten as two way mode.
As such, players are sometimes forced to implement public services.

Do you have road signs saying that that road is only one way?

Thank you for your advice. Certainly one-way signs seem to help prevent this. As pointed out in another thread, it means that oneway_mode and oneway sign exist independently and they are not linking properly.

Thank you for your report.

This is an inherently very complex problem to solve, as this would require a very deep pathfinding algorithm to check whether there are any other roads to connect to an existing city. The current system for connecting industries with roads relies on existing code from Standard, so this addition was intended to be lightweight.

If anyone can come up with a working solution to this, that would be splendid, but I expect that this would be a major project.

The main purpose of such roads is to allow players connecting the industries without expensively affording land for roads first.
A positive sideffect is commuters reaching industries by cars.

A very simple solution would be to retain the road mode of existing roads while using the exact same road constuction algorithm as now.

I am aware this is not a perfect solution, but it's simple and still much better than the obstruction caused by industy spawning at the moment.

I have now implemented this - I should be grateful if you could test with to-morrow's nightly build.
