Demand Generation from census data
Hi, I'm new to MATSim, I'm a research intern who's currently working on traffic and noise pollution simulation. I found some problems with creating the plans input file for MATSim. I have a shapefile of my city of interest that has multiple zones as well as an excel file with statistics for each of those zones (Population count for each age goupe, gender, salaries...). I haven't found a way to create the proper plans file from this data, can anyone help me ?
It depends on what kind of MATSim simulation you plan to conduct. There are two options: either trip-based or plan-based. The former is relatively more accessible, which you can produce by creating some dummy agents with one leg during the simulated day. But I have never tried working with it.
Another option would be creating a plan-based file, in which you need detailed information about each individual's activities and travels within your study area (example: https://github.com/matsim-org/matsim-example-project/blob/master/scenarios/equil/plans100.xml). To the best of my knowledge, the existing method always requires additional data besides the census if you want to do it for a city. For instance, the plan of many MATSim scenarios in Germany is generated via mobile data and openly available. If you are in France, there is also a plan generation pipeline that uses open-source data in France (https://github.com/eqasim-org/ile-de-france). If you want to use it, you need to find some special data that tells the OD matrices of different purposes of activities (e.g. working, schooling) to the best of my understanding.
One can also use some local household travel surveys and translate them into MATSim demand. But some papers say the model generated via that will lose a bit of policy-sensitivity.
We here in Brussels also have an R pipeline that adopts ubiquitous data and produce MATSim plan file. But still, we also use another special data from local telecom provider :\ Although some other data can also be used as an alternative, again, you need additional data besides the census.
That's almost everything to the best of my knowledge for MATSim demand generation :) Others may know more.
Thank you for your answer, I'm actually working on québec city, canada so I don't have access to those pipelines. However I can get the OD matrices, is there any tutorial on how i can use the census data and the od matrices to createthe plans ?
Hi, a colleague of mine in Laval is working on MATSim Quebec city scenario. She has generated a population plan and calibrated it. I am not sure if it is publicly accessible, but I think she may have some leads for you on where to start. I will ask her if you want her contact.

You can reach her through this email if you want to talk to her: [email protected]
