[sumo-user] More randomly spreaded traffic

[Alex Cerioni <cerio_alex@xxxxxxxxxx>]

Hi,
I'm using activitygen with a statics.stat.xml file generated by me with this specifics:
-inhabitants = 5000
-households = 5000
-carRate = 1
-unemploymentRate = 0.12
-freeTimeActivityRate = 0.6

-uniformRandomTraffic = 0.2
-departureVariation = 0.6
//- each edge has the attribute "population" between 0 and 10 and "workPosition" between 0 and 2.
//- no busses[. . .]
To generate the trips.trips.xml file I use this command

activitygen -n network.net.xml -s statitic.stat.xml -o trips.trips.xml --random

Then I run:

duarouter -n network.net.xml -r trips.trips.xml -o routes.rou.xml --random --ignore-errors

THE QUESTION IS: how can I prevent those traffic jams (see attached photo) that are in the simulation? I would like vehicles not taking only shortest path, but a more spreaded and random routes from home to work and vice-versa.
I tryed using duaiterate.py (https://sumo.dlr.de/wiki/Demand/Dynamic_User_Assignment#Iterative_Assignment_.28Dynamic_User_Equilibrium.29)
but it gives me this error

"-------------------------------------------------------------------------------

['duarouter', '-c', 'iteration_000_trips.duarcfg']

Loading configuration... done.

Error: No connection between edge '4018838#0' and edge '168773942' found.

Error: Mandatory edge '168773942' not reachable by vehicle 'randUni2046:1'.

Error: The vehicle 'randUni2046:1' has no valid route.

Quitting (on error)."

Sorry for the long mail but I tried being more specific andmore synthetic as possible.

Thanks.

Regards,
Alex
