Re: [sumo-user] flow vs trips
And when creating the Vehicle Type Distributions entry, I would have there the probability of distribution. Do I still need probability entry in the flow entry?

Best regards,
José

I just found out that the newTrips.trips.xml have the flow, but only if I have --period and --binomial parameters set, If those are not present then I get only trip entries.

Thanks for all the help!

the flows are inside the file newTrips.trips.xml.
You can load that directly into sumo.
The route file is generated by duarouter in the background and that always expands flows into vehicles.
You should define the vTypeDistribution in an extra file just as it is explained in the wiki (use a distribution instead of vType 'myType' as in the example).

Hi Jakob,

When I run randomTrips.py -n NETCONVERT.citycentreV2.net.xml -o newTrip.trips.xml -r newRoutes.rou.xml --weights-prefix=NEW --fringe-factor=100 --flows 100 --validate
I get inside the newRoutes.rou.xml file just route entries, is there an option to generate the flow file?

If that is supposed to be the file, then to that I should add the entries of vType and define the probability and distribution?

Or am I missing something?

Best regards,
José

Thanks Jakob I will take a look at it

When you set option --flows 100, the randomTrips should 100 flow entries.
If you want to change the type proportions manually, then use a vTypeDistribution and generate trips / flows that reference the distribution.
You can then adapt the type probabilities in the distribution before you start the simulation:

But with that option I do not have a flow entry.
I want to be able to tell to have a flow with 200 vehicles, where 10 percent are of Type A, 90 percent are Type C, and be able to change those values every time.

randomTrips.py supports option --flows

Great! Thanks Jakob, and do you know if as for Trips, is it possible to generate a flow file in the same way with a script from the sumo tools directory or alike?

Best regards,
José

Hey everyone,

I was using some flow entries to define the amount of vehicles taking certain route.
When creating a trip file with randomTrips, is it possible to tell how many vehicles do I want to be generated in the network? This to simulate heaving, medium and low traffic.

Best regards,
José
