Changelog

All notable changes to this project will be documented in this file.

6.4 (2025-01)

  • Improved facility locations
    • OSM tag filtering has been improved to reduce number of wrongly assigned facility types
  • Update work location assignment within Berlin
    • Work locations now use weighted sampling during location choice
    • The weight is based on an attraction factor and zone specific probabilities determined from survey data
  • Updated GTFS schedule
    • The schedule is now based on the 2024-11-19
    • Note that there are major changes how stops and links between them are created
      • Stops having the same gtfs parent_id and route types are merged together, allowing agents to find better PT connections
      • The PT network is created with loop links (on each PT stop) instead of duplicating stops, which also improves connections
      • The Berlin Ringbahn is manually adjusted so that each train drives multiple loops the whole day
  • New income calculation
    • In previous versions income was used directly as household income from the survey data
    • Now, the income is calculated as personal equivalent income, which is the household income divided by equivalent household size
    • Corresponding attributes have been added to the population file
  • Bike mode updated and recalibrated
    • Bike is now routed on the network, which results in more realistic travel distances
    • Bikes are not simulated on the network, and no link events generated yet. This will likely be added in future versions.
    • The road network includes bike infrastructure and corresponding attributes
    • The bike infrastructure is not fully complete yet, and has to be carefully evaluated first for bike centric studies
    • The avg. bike speed has been set to match SrV2018 survey data (~10.3 km/h)
  • New dashboards
    • PT Transit viewer
    • Emissions
    • Noise

6.3 (2024-07)

  • Include additional trip analysis and updated dashboard
    • Mode share is now analyzed by age, income, employment, economic_status
  • Updated population, which now include reference modes for certain persons
  • The reference modes represent modes that a person has actually used in reality
  • Allows to evaluate the quality of the model in terms of mode choice
  • ReplanningAnnealer module is now activated by default

6.2 (2024-06)

  • Updated network and gtfs schedule
    • Network is now based on late 2022 osm data
    • PT schedule is based in mid 2023, earlier data of this feed was not available
    • The network conversion now uses a SUMO converter, a microscopic representation of the network will be available as well
    • Free speed of the network has been calibrated as described in the paper "Road network free flow speed estimation using microscopic simulation and point-to-point travel times"
  • Walking speed increased to match reference data
  • Recalibration of mode constants (ASCs)
  • Updated commercial traffic, especially the trip duration should be more realistic
  • Added a run class for DRT scenarios
  • Please note that the 6.3 version is released nearly at the same time
    • Because of that 6.2 was not calibrated to the same accuracy
    • Rather use the newest version, which also includes all features of 6.2

6.1.1 (2024-06-11)

  • Fix ASCs in tbe 6.1 config
    • The calibrated ASCs have not been correctly copied to the 6.1 config, this is now fixed.
  • All input files remain the same
    • The existing output remains the same as well, because this run was using the correct ASC values

6.1 (2024-04-17)

  • Trips from survey data are filtered slightly different

    • Previously, trips that did not have the flag E_WEG_GUELTIG, have been ignored.
    • However, this flag is not considered in SrV reports, or the Berlin website that reports the modal share.
    • To be more consistent with these reports, these trips are now considered as well.
    • This leads to slightly different mode shares compared to the previous version.

  • Commercial traffic was updated to include recent changes

    • Temporal distribution was updated according to survey data
    • Separated car and freight/truck mode

6.0 (2024-02-20)

Initial release of the updated MATSim Open Berlin scenario. For more information, see the paper (tba.)
