[sumo-user] Using TAZs for random trips

[Rohan Verma <rohanverma446@xxxxxxxxx>]

Dear community,

I created TAZs using netedit.exe. The TAZ file created has the following:

<tazSource id="-E11" weight="1.00"/>

<tazSink id="-E11" weight="1.00"/>

1. Does this mean that edge "-E11" is used as a source as well as a sink? Or does this mean that edge "-E11" is the source and its own sink?

2. Also, I want to create random trips from one TAZ to another. I want a random edge from one TAZ to be used as a source and another random edge from another TAZ to be used as a sink with random flow. Is this possible? If yes, please direct me on how to achieve this.

3. Can a stop also be assigned when using TAZs to generate trips?

4. Is it necessary to have an OD matrix to use TAZs?

5. To create a hypothetical OD matrix to be used in SUMO, what should be the format? Should we use nodes or lanes/edges? 

Thanks and regards,

Rohan
