Re: [sumo-user] geometry.remove.min-length

[Lukas Ambuehl <kitatsuab@xxxxxxxxx>]

Thanks Jakob for the quick follow-up. 

Would that be a potential enhancement?

Similar to geometry.remove.width-tolerance, you could set a threshold? 

I am asking because I am using meso, and as discussed previously, short edges have adverse effects  (and this seems to propagate onto other edges as well).

Hello,

geometry.remove will never join edges that differ in the number of lanes. The option geometry.remove.min-length only applies to attributes such as speed, permissions and width.

regards,

Hi all

I am trying to reduce the number of short edges in my network.

I use the following netconvert options: 

     <geometry.remove value="true"/>

     <edges.join value="true”/>

     <geometry.remove.min-length value=“30"/>

     <geometry.min-dist value=“20"/>

     <geometry.remove.width-tolerance value=“2"/>

     <geometry.max-segment-length value="200”/>

I thought that geometry.remove.min-length  would control for the max. length of an edge being merged with another one and geometry.remove.width-tolerance for the difference in numbers of lanes allowed. However, when running this on an OSM derived network, some edges really do not want to merge with others. See attached screenshot of an edge < 30m, which doesn’t want to be merged. Does it somehow depend on the junction that follows or on the length of the other edges?

Any ideas on how to go about this? (I can also provide a MWE if needed)

Thanks

Lukas
