The Replan digital twin models the street network, timetable and population of a region: every simulated person plans a day and reacts again when lines, fares, zones or streets change.
A digital twin for transport planning is a model of the region on which measures are tested before they are built. Replan builds it from open data in one working day and calibrates it with your counts. Replan Transit plans the service on it, Replan SIM simulates the demand.
OpenStreetMap for roads, paths and footways.
GTFS for lines and departures, added to with your planning versions.
Census for residents and jobs, a synthetic population with age, household, income and car access.
MiD, SrV and Mikrozensus for trips, modes and daily schedules.
Counts, ticketing data and your current network calibrate the twin. No personal data is needed.
Existing traffic models are converted where suitable.
A first digital twin of the region runs, built from open data.
Timetables, planning versions, vehicle types and cost parameters from your current system.
Calibration against your counts, checks on cases your team knows. Every deviation is visible.
Four training sessions, a short guide, and the same team stays. Onboarding
Boardings and alightings per stop, loads per section, transfers.
Modal split shift per scenario, baseline against variant.
Who gains and who pays, by income, age and district.
Lines, timetable, blocks and cost in Replan Transit on the same twin. Transit service planning
| Macroscopic traffic model | With Replan | |
|---|---|---|
| Basic unit | Zones and matrices | People with a daily plan |
| Result | Loads per link and line | Loads and effects per person, group and time of day |
| Service planning | Usually a separate tool | Replan Transit on the same twin |
| Data | Surveys and counts | Open data, refined with counts and ticketing data |
| Access | Depends on the tool | In the browser, results as link, map, table and GIS layer |
Typical tool types, not single products. Many teams use both side by side.
MOIA (Hamburg), Klimaschutzrat Berlin, Netivei Ayalon (Israel), IZES (Saarbrücken) and HSU (Hamburg).
HAVAG (Halle), LVB (Leipzig), MDV (Mitteldeutschland), THÜSAC (Altenburger Land), NASA GmbH (Sachsen-Anhalt) and MUKMAV (Saarland).
A digital twin in transport is a model of a city or region with street network, timetable and population, on which measures are tested before they are built. In Replan every simulated person plans a day and reacts to changes in service, fares or streets.
A first digital twin of any German region is built from open data in one working day. Calibration against your counts and checks on known cases follow within a few weeks. Onboarding and training →
To start, only open data: OpenStreetMap, GTFS, census, MiD, SrV and Mikrozensus. Your counts, ticketing data and planning versions refine it. No personal data is needed.
On MATSim, an open simulation framework from TU Berlin and ETH Zürich. The twin is calibrated against passenger counts, and the method is peer-reviewed in Transportation Research Record 2025. MATSim explained in one minute →
The twin built for you is yours. It sits in its own tenant, encrypted and hosted in Europe, and can be exported in open formats at any time.
Get started
In 30 minutes we show a digital twin of your region and run one question: a line, a fare or a zone.
