Re: [sumo-user] stop output and trip output do not match
When I run your simulation (run.sumocfg), I get 2341 loaded/unloaded persons in stop-output.
I used attributeStats.py -e stopinfo -a loadedPersons stops-out.xml -p 5
and this gives 622 stops with an average of  3.76367 loaded/unloaded

At the end time of 36000 there are still 28 persons in the simulation according to the log.
You can also check this by comparing the input count (9000 persons) to the tripinfo output count (8972 persons).

Looking at the simulation reveals that these persons are waiting at a busStop after all buses have already left. Some of them such as person 6064 have already used a bus by that time which creates a discrepancy between loadedPersons and ride count in tripinfo-output.

The pedestrian collisions are (among other things) caused by vehicles that drive on the sidewalks due to being configured with vClass="ignoring".
The pedestrian jamming (which could be caused by mis-dimensioned sidewalks/crossings) could be responsible for persons missing their buses.

Jakob

Hello,
"tripinfo-output only contains persons that have completed their whole itinerary (all walks and rides)"
The above may be true, but your later statements explain the issues partially. I changed the time from 3600 to 36000, and also, restored the bus route input file. However, I still find that stop-output contains 2318 boarding and alighting, whereas trip-output contains 2310 trips for passengers. I suspected that maybe those 8 passengers are stuck in jams and/or collisions. To my surprise, I found that the number of jams and collisions are certainly more than 8 (at least 5 times of it). Then, what is the reason for having such a gap between stop-output count and trip-output count.

When I ran the same simulation using TraCI, I found that total trips on buses 2341.

I am attaching the latest network which I used for simulation in the command line as well as in TraCI. Please recheck, there might be some issues in the software itself ( I am using a version which was updated on June 25, 2020).

Since your configuration ends the simulation at step 3600 it will prevent output of all persons still travelling at that time even though they already rode a bus and thus show up in the stop-output.

Hello,
Again, I tried this with the latest development version of SUMO which was updated on June 25, 2020. However, the same issue continues, i.e., the number of boarded and alighted persons in stop output is more than the number of records in trip output.
Kindly, look into it at earliest.
thanks and regards,

Hello,
Recently, I implemented public transit lines in SUMO. I encountered that the number of passengers boarded at a stop according to stop output, does not  match with the number of passengers making successful trips according to trip output. I was assuming that every passenger who boards into some bus at any stop has an entry in trip output as well. I tried with TraCI as well as a simple command line, but in either case, I found that the passenger count varies. Typically, the total number passengers boarded (as per stop output) is greater than the total number of passengers in the trip output. However, when I extracted additional data through TraCI, then I found that the number of passengers at various stops as per stop output is the same as the extracted information about each passenger through TraCI.

I am attaching my network along with TraCI code (demo-i.py) to be tested by others. Also, I am attaching a few csv files which I have extracted from the xml output files for easier reference.

Please clarify if the stop output count of passengers has to be the same as the number of trips as per trip output or not.

thanks and regards,
Dillip Rout
