Re: [sumo-user] Problem with Elevation

Hello Jakob,

 

Does this option influence the travel time of the vehicles?

I rebuild my network with this option. I get smaller but still high slopes in positive and negative (for example -30,87° this edge of my first message). Is there anything else I can do?

see https://github.com/eclipse/sumo/issues/13318

A workaround is to build (or rebuild) the network with option --no-internal-links, though this has the side effect of using a less detailed intersection model (https://sumo.dlr.de/docs/Simulation/Intersections.html#internal_links)

 

splitting the network would not help.

Hello Jakob,

 

 

I added elevation data to my net using Geotiff from NASA Earth Observation. 

 

Now I get implausible values for the slope. For example this edge. If the edge would rise linear between the two junctions, the slope would be 2,09°. But in my output file the values jump from -44,2° to 8,2°

 

How is the z value for edges between two junctions computed? Would it be helpful to split the edges to get more junctions?

 

I atteched my network. 

 

 

Thank you for your continuous support

 

Regards,

Florian
