I have no experience with the carsharing contrib, so I cannot comment on the first question.
How is the score for stuck and abort determined or calculated?
see ScoringParameters.java, L161-164
abortedPlanScore = Math.min(
Math.min(marginalUtilityOfLateArrival_s, marginalUtilityOfEarlyDeparture_s),
Math.min(worstMarginalUtilityOfTraveling_s-marginalUtilityOfPerforming_s, marginalUtilityOfWaiting_s-marginalUtilityOfPerforming_s)
) * 3600.0 * 24.0;
So it is essentially a very bad (a very negative) score value that gets added to the already accumulated score of the stuck agents.
Hi @mrieser, Thank you for the reply. I will go through the ScoringParameters to further my understanding.
Dear everyone, I tested a carsharing scenario using Sioux Falls. I created 40 stations, and in each station there are 120 oneway-vehicles, 80 twoway-vehicles, and 80 parking spots (fleet size is 8000 vehicles). I randomly assigned carsharing membership to 16822 agents (20% of total population). For agents with membership, I modified their attribute
carAvailability
from always to never. Further, if those agents have car asleg mode
in their plan, I modified it from car to walk.I noticed in the scores figure that the plan's average and average worst score appear to be diverged from the average best or executed scores after the strategy innovation is disabled. I analyzed the event output file and used the stuck agent analysis in VIA for further understanding. I found out that 82% of all stuck agents (197 agents) are the agents with carsharing membership.
Here comes my questions regarding the divergence (the decline) in plan's average and average worst:
Any lead or help is immensely appreciated. Thanks
For your reference, please have a look at the strategy setting below:
