Re: [sumo-user] SUMO default parameters
The lcOvertakeRight error is a bug (https://github.com/eclipse/sumo/issues/5991). We're  planning a hotfix release tomorrow, so just upgrade to that.
There is currently no way to get the default values for all attributes. I've updated the documentation though:

Thanks, Jakob.

by setting xml-validation to never, this new error will raise:
'''
Error: Invalid Lane-Change-Model Attribute lcOvertakeRight. Must be greater than 0
Quitting (on error).
'''

As you guessed right, I've used multi-vehicle classes in defining vehicle type distribution. by correcting the "speedDev" attribute for each class the results are now closer to the first run but it stills not the same. is there any way to get SUMO default values in the output?
the results are attached.

With Best Regards,
Mohsen

This is an error in the schema files (now corrected). Please try with lcOvertakeRight=0 and sumo option --xml-validation never.
Also, if you define a vtype with vclass truck,trailer,coach or delivery, they will get a default speedDev of 0.05.(https://sumo.dlr.de/wiki/ChangeLog#Other_6)

Hello,
I've created a scenario with 3 replications with a set of seed numbers. whenever I run the simulation model with SUMO default parameters for car-following and lane-changing models for twice and more, I get the same results, as expected.
but the problem is when I try to manually set those parameters to their defaults, the results considerably will change.

these are parameters that I've tried to set it manually to their defaults:
['speedFactor; 1.000', 'speedDev; 0.100', 'minGap; 2.500', 'accel; 2.600', 'decel; 4.500', 'sigma; 0.500', 'tau; 1.000', 'lcSpeedGain; 1.000', 'lcKeepRight; 1.000', 'lcOvertakeRight; 0.001', 'lcSpeedGainRight; 0.100', 'lcAssertive; 1.000']

source: https://sumo.dlr.de/wiki/Definition_of_Vehicles,_Vehicle_Types,_and_Routes
SUMO version: 1.3.0

also in the source link, it states that the default "lcOvertakeRight" parameter is 0 but if I manually set it to 0 SUMO will raise the error below:
'''
Error: value '0' must be greater than or equal to minExclusive facet value '0'
 In file '...\315701.vtype.xml'
 At line/column 5/133.

Quitting (on error).

With Best Regards,
Mohsen
