Re: [sumo-user] Crowding at bus stops

Dear Jakob,

 

Thank you for your swift response.

 

Attached you find the stop-file and the config file I used, which only creates empty files of no type.

 

Thank you.

My apologies for suggesting the wrong tool. It's description has been extended to clarify the ambiguity in what is being counted.

W.r.t. computePassengerCounts.py, this tool is working in our tests and counts the number of passengers aboard vehicles. Feel free to provide your stop-output file to check why the results come up empty.

Upon further consideration, stop-output is not well-suited to analyze crowding since it only records the number of passengers at vehicle arrival but doesn't track the number of persons who enter / leave a stop between vehicle arrivals (any given person might either continue with walking after having arrived or continue to wait for a continuation ride).

A better output would be tripinfo-output since it records the start times of rides as well as the prior waiting time.

There is currently no tool in SUMO that would perform the aggregation. Pull requests are welcome.

 

regards,

Jakob

Thank you for pointing out this tool.

 

I tested it on my stop-output. Unfortunately, the output only shows the time and number of buses occupying a stop, but not the number of passengers waiting/arriving at the stop.

I also tested the tool computePassengerCounts.py to analyse the stop-output, however, this tool just creates empty files, when the parameter for csv is set to “False” or no files, when it is set to “True”.

 

Is there maybe another way?

 

Thank you.

The python tool output/computeStoppingPlaceUsage.py analyzes crowding at bus stops based on stop output and might fit your needs.

see https://sumo.dlr.de/docs/Tools/Output.html#computestoppingplaceusagepy

Hello,

 

is there a more convenient way to analyse the crowding at bus stops than using the stop_output and counting the number of arrived passengers before each bus departure?

 

Thank you.

 

Kind regards,

Frederik
