matsim-vsp / matsim-python-tools Goto Github PK

Hi,
Thanks for the interesting project!
I was wondering if you intend to also include python tools for tasks beyond data analysis?
Writing XMLs for example: https://github.com/eqasim-org/ile-de-france/blob/develop/matsim/writers.py
In the link above, the code is perhaps specific to one use case but it could probably be well generalizable.
Kind regards, Davi

Fresh installation of matsim-tools throws this error:

If this call came from a _pb2.py file, your generated code is out of date and must be regenerated with protoc >= 3.19.0.
If you cannot immediately regenerate your protos, some other possible workarounds are:
 1. Downgrade the protobuf package to 3.20.x or lower.
 2. Set PROTOCOL_BUFFERS_PYTHON_IMPLEMENTATION=python (but this will use pure-Python parsing and will be much slower).

We might want to update the generated protobuf files.

Hello,

Now, I have a project, in which I need to analyze the output files and obtain some useful data.

I hope to obtain the map data and the state of each edge in the map at every time. More detailly, I want to obtain the data that for each time point, how long a vehicle will take to traverse a route (edge).

May I ask if it is possible to implement by using this python-tools.

Thanks!!!

Best,

In xml, we have

	<person id="01067005_518">
		<attributes>
			<attribute name="age" class="java.lang.Integer">45</attribute>
			<attribute name="district" class="java.lang.String">Dresden</attribute>
			...
		</attributes>
	</person>

How to you get to, say, age?

Hi!

I'm using the plan reader to analyze the plan file. But I have met some problems here. I can't filter the plan file after I got the matsim.plan_reader generator. For example, I want to get all legs with mode= pt in the plan file and no matter what trip type it was. And I use the code as follows:

for person, plan in plans: pt_activities = filter( lambda e: e.tag == 'leg' and e.leg['mode'] == 'pt', plan)

It seems that I didn't filter the activities I want.

How should I work with that? I attached the plan file that I am using now.

Thanks a lot for the help!

Hello, I'm trying to run geo = net.as_geo() but I get this error:

CRSError: Invalid projection: Atlantis: (Internal Proj Error: proj_create: unrecognized format / unknown name)

could you please let me know how can I solve it?

Thanks

I just tried reading the episim input plans ... that uses up time (so it is going through the file) ... but it does not return any material.

Reason, as far as I can tell, is that persons without plans are not read.

In this case, however, we need persons without plans, since we store the person attributes in those persons.

Could you please change that? Thanks.
