Re: [sumo-user] distribute flows on 2 or more lanes

[IT Tech <aekralem21@xxxxxxxxx>]

If I understand it correctly, you have an edge with one lane and then another edge with 3 and the last is only one lane,

Maybe you can set departLane in the second edge as random.

Hi, thanks for the answer.

Maybe I haven't clearly explained the problem.

I've got a single departure lane and I must force different flows to distribute in a homogeneous way on a road of three different lanes. 

Also arrival Lane is only one.  

The problem is that these flows occupy only the rightmost lane.

I realize that I haven't explained the problem very well and I apologize.

Hi, Luca

You can use this code to distribute the load on the different lanes you have : 

here the code distributes 300 vehicles over three lanes equally but you can distribute the load however you want. 

<flow id="f" type="" departLane="0" arrivalLane="current" number="100" from="edge" to="edge"/>

<flow id="f1" type="" departLane="1" arrivalLane="current" number="100" from="edge" to="edge"/>

<flow id="f2" type="" departLane="2" arrivalLane="current" number="100" from="edge" to="edge"/>

Hi, 

i'm using Sumo to simulate multi-modal traffic within a port. 

The problem that's occurring most frequently is that flows using only the rightmost lane, when instead they could use also the other two lanes and therefore distribute in a more heterogeneous way. 

This thing creates an unrealistic traffic of queued vehicles which actually could use very well the other available lines.

To resolve this problem I thought to assign for each flow an "arrivalLane" but, for a series of problems, i can't use this method anymore. 

I think that I need a dynamic distribution of vehicles according to the available space. 

Any advice is welcome. 

Thanks.
