Re: [sumo-user] netgenerate : grid network , customising parameters for certain edges and junctions
Dear Jacob, thanks a lot for your help.
As per your suggestion, I explored netedit and in the documentation It is mentioned that netedit can do anything that netconvert does.
Accordingly, I tried to create multiple grid networks (a higher speed TL controlled network, and two lower speed unregulated networks with x,y displacement) and merge them using netconvert. However, few edges and junctions overlap. Is there any option to  keep only one  edge/junction of the overlapping ones? 
Or the manual approach as suggested by you in the earlier email would be better?  In that case, what is the selection file template? Please help.

Regards,

Manish

build a grid with netgenerate, then use netedit to select some of the edges and change all of their attributes at once.
If the network is large you could even prepare a selection file outside of netedit and then just load that selection to avoid the need for selection-by-clicking

Dear Jacob, thanks a lot for your reply.

Actually, I do not want to randomize the number of lanes or TL deployment in grid network. 

Instead, I need a grid in which the parallel roads have different configuration: e.g. a Major roads (3 Lane, TL controlled, higher speed) and the parallel low capacity road (e.g. 2 lanes, unregulated, lower speed).

Is it possible to do this using netgenerate? Can you suggest some alternatives?

Regards,

Manish

1. you can randomize number of lanes (for all network types) by setting options
--default.lanenumber MAXNUM --rand.random-lanenumber

The latest development version also supports option --random-type (together with option --type-files)

2. You can use option --tls.guess --tls.guess.threshold FLOAT. This uses the sum of incoming lane speeds to decide whether an intersection gets a tls or not. Together with random lane numbers or speeds (via random types) you will get random traffic lights.

Jakob

Dear SUMO users,

1) I am trying to design a Grid network which should have  two-three  different types of edges  (having  different properties e.g. number of lanes and speed limit).

I checked the template file of netgenerate but did not find any option for the customization. I encountered a link about  Edge type but I have no Idea whether it can be used with netgenerate.

Please suggest a way out for this.


2) In the Grid network, I want a few main junctions to be TL controlled, and others should be uncontrolled/unregulated.
 
In the template file, I found the tag <unregulated_nodes> with <keep-nodes-unregulated.explicit value="STR[]"> . I do not understand how to use this feature  to declare a few junctions as Unregulated (How can I know the junction IDs before the network is created?). Am I missing something? Please suggest.

Best Regards,

Manish
