Re: [sumo-user] conservation of vehicles to one edge to the following?

[Natalia Liora <lioranat@xxxxxxx>]

Hi Michael, 

thank you. I mean that in case I define at the rou.xml file that in specific edges (e.g. from="1" to=“5")  I have a certain number of vehicles per hour (e.g. vehsPerHour=“100”) this should finally mean that in an one hour simulation the total number of vehicles counted in the specific edges (1, 2…) would be the same (for each edge). Is this right?

Also, in case I define the output file for the traffic measures in the additional file, this would be something like this?
<edgeData id='ed1' file='edge_all.xml' begin='0' end='3600' >

Could I get an output file for each vehicle type? In that case , should I define the vTypes above (similarly to the emissions output files?)

Thanks a lot.
Best regards,
Natalia
