kit-ifv / mobitopp Goto Github PK

I cloned this git repository and – without changing anything – ran ./gradlew runPopulationSynthesis runSimulation in the project directory.

After going through the output and results folders I quickly identified results/simulation/demandsimulationResult.csv to be the output file of my interest. This file contains approximately 40.000 rows with each row describing one trip of one person including start time, end time, start geopoint and end geopoint.

However, after going through the first couple of rows of this file I quickly identified a problem: The start geopoint and the end geopoint always only lie a few meters apart from each other. To confirm this problem on a larger scale (I could not go through 40.000 rows manually), I imported demandsimulationResult.csv into Apple Numbers. Next, I added conditional formatting to the column distanceInKm to determine whether any trip has a distance of more than 1 km. As it turned out, no trip has.

If I understand mobitopp and its outputs right, this result is not intended: One trip should represent the way of one person from one place to another. Thus, trip distances of a few meters don't make any sense.

In conclusion, there are several possibilities why I experienced this issue:

1. I did something wrong using mobitopp. In this case, I would love to get some feedback.
2. mobitopp does not run out of the box and needs some more input files to work correctly. In this case, I would love to know what input files it needs.
3. This is an issue on the part of mobitopp.

In general, I am missing documentation for mobitopp. As stated in README.md, the outputs of mobitopp are quite self-explanatory. However, what is not self-explanatory are the inputs that mobitopp needs.

I am looking forward to an answer and attached my demandsimulationResult.csv file.
