[sumo-user] Modifying network

[Rohan Verma <rohanverma446@xxxxxxxxx>]

Dear community,

I have a randomly generated road network saved as .net.xml. Each of the edges is a single lane in this network. And guessing of opposite direction lanes usable for overtaking is enabled. I want to convert all the edges to two lanes. Since it is not a small network (consisting of 212 edges), I do not wish to use NETEDIT GUI. Is there another way to do it? 

I tried inserting the second lane directly in the XML file (example given below), but this creates a problem with lane connections at junctions and with overtaking connections.

<lane id="1_1" index="1" speed="13.89" length="175.24" shape="501.60,310.40 501.60,485.64">

            <neigh lane="112_1"/>

</lane>

Kindly suggest a more suitable approach.

Any help is greatly appreciated.

Thanks and regards,

Rohan
