Re: [sumo-user] Influencing route-selection

[Jakob Erdmann <namdre.sumo@xxxxxxxxxxxxxx>]

Hello,

- the via element defines mandatory edges

- the preference for paths with intersections is a known bug: https://github.com/DLR-TS/sumo/issues/752

possible solutions besides using via:

1) load fully defined routes into the simulation. You could get these by loading trips into duarouter. To influence route choice you can load custom edge-weight files that penalize the paths across the intersection (or rather the edges leading into the intersection). Note, that this is deterministic

2) influence route choice within the simulation. See http://sumo.dlr.de/wiki/Simulation/Routing

The 'routing device' approach also allows non-deterministic route choice

3) artificially lower the speed limit on edges leading into the intersection

regards,

Jakob

Hi,

I have a simulation where I have two possible ways between two points of the map.

The first one is going through a difficult intersection with traffic lights.

The other one is an overpass, a much easier and faster way in the real life.

I found out that while there are no congestions around the intersections, the flow prefers this way. I however want to influence them to use the overpass. Is there any way to do that (besides the "via" parameter of the flow)?

If the "via" parameter is the only way to do that, is it mandatory for them? Or simply a probability variable of some kind?

Thanks for you reply in advance!

Best regards,

Levente
