Re: [sumo-user] SUMO default parameters
|
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.
This is an error in the schema files (now corrected). Please try with
lcOvertakeRight=0 and sumo option --xml-validation never.
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_RoutesSUMO 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
