Re: [talk-au] Melbourne Intersections with duplicate ways and turn lanes

2021-09-14 Thread me

Thanks Andrew,

I've reached out to the user on a changeset, and will hopefully have a 
good conversation about it.


In the meantime, I've found about 30-50 intersections with these 
duplicate ways and lanes. Would it be useful to add notes, or fix me 
tags to those intersections? I'm wary about flooding any feedback 
channels with many instances of the same problem, but it could help keep 
track of where work is needed?

Thanks I see what you mean by these changes (much easier to visualise 
in OSMCha).


Usually I see this as an older style mapping, before turn lane tagging 
was more common and sometimes done for routing so that people were 
warned earlier. But these days it's much better to use turn:lanes 
tagging and only split the way at the point where you can no longer 
physically change lanes.


It's possible to revert changesets, but it's not always 
straightforward.


Leaving a changeset comment is the best first step, as they might not 
be aware of standard practice and other tags like turn:lanes.

Thanks Andrew, that was my last understanding as well. In particular, 
modeling right hand turns as separate, curved ways when there is no 
separate roadway.


Here are of changesets which introduce the types of issues I mentioned. 
They mostly seem to be around dual carriageways.

I haven't been able to find an example of where it was an issue, but 
generally the rule of thumb is only using separate ways when they are 
physically separated, so sometimes you're splitting into two parallel 
ways for either direction, but not usually for each lane of the road in 
a single direction.

Hi,

I'm relatively new, but I wanted to bring something g to your

I came across a couple of intersections that seemed overly complicated; 
they had lots of turn lanes drawn and were very messy. I created an 
account, learned the standards for intersections and tried my best to 
fix them. I started at Heidelberg Rd/Chandler Hwy, and then found more 
on Punt Road/Hoddle St. I changed those as best I could as well. Then I 
saw more, and more. Once I started looking, it was everywhere; 
intersections with multiple ways for lanes, two or three turn lanes 
with broken restrictions. The West Gate has some sections of parallel 
lanes as ways for a few hundred meters. Whenever I try and route using 
one of these intersections, there are multiple confusing steps and 
"forks" that don't exist in reality


Almost all the edits have been from one user; I've sent them a message 
on their most recent change set, but I'm daunted by the scale of the 
fixes required. Does this group have any suggestions on where and how 
to start?
