Re: [sumo-user] Vehicle following list of lat longs
|
My only issue with the duarouter method is that it won’t map to latlongs for short distances on a long edge. For example, if I had a vehicle traveling on lat longs that only span 1/3 of an edge, it would map to the entire edge. This is what happens when I get the network from osm.
Following up on the other proposed solution, if I create a single edge with many geometry points, it would map the path the vehicle takes perfectly, but, I wouldn’t be able to control the vehicle speed over the path. For example, if I had data down to the second on vehicle speed and it’s latlong coordinates.
Any thoughts on another option?
The *lonLat attributes are only usable with 'duarouter' at the moment. This will generated a route with edges that you can run in sumo.
Are edges required? For example, let’s say I want to visualize a vehicle driving circles in a parking lot.
I found the fromLonLat and toLonLat attribute and was trying to use that but it seems the program doesn’t like that I have no edges.
“The route for trip t_0 has no edges”
The usual approach would be to match the points onto a road network (i.e. imported from OpenStreetMap).
However, if you don't care about road infrastructure at all, you could also define a single edge with as many geometry points as you have.
You could put the list of lon,lat pairs directly into the edge 'shape' attribute and then build the network with --proj.utm.
I have a large list of latitude and longitude points I want a vehicle to follow (over 1000). The points involve multiple turns along with other behaviors such as lane merging.
Is the best way to do this to create junctions for each point and then to create edges between every junction? (I.e. 1000+ junctions and edges) Is there a more streamlined way to do this?
Thanks,
Tom
