Re: [sumo-user] Question about smoothing edges

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Think of the corners as 'Bézier control points' rather than as points that the road must pass through (i.e. make them stick out further than the curve you actually want).

Hi Jakob,

Thanks for your reply. It seems we can't anchor some geometry points when smoothing edges. If a corner angle is not sufficiently large, then the related edge will be straightened.

Best,

Yu

The following works for me in 1.13.0  (and should work for you too)

1. create an edge

2. use move mode to create a geometry point that forms a corner in that edge (i.e. a 90 degree bend)

3. (optional) create further geometry points

4. (optional) use F10 -> Formats -> opendrive.curve-resolution setting to configure the spacing of added geometry points

5. right-click on edge and select 'smooth shape'

Hi all,

I tried to use “smooth edge” to smooth curved edges, but it resulted in directly straightening the edges even though I have set geometry points. Can anybody kindly show me how to address this problem?

Best,
Yu
