ANTONIN Passenger Transport Model for Île-de-France (greater Paris area)
Significance has developed a new version of the ANTONIN model for the Île-de-France region. The Île-de-France region is diverse, encompassing the highly urbanized city of Paris, its suburbs, and more rural areas. The latest update is based on the EGT travel survey data from 2018-2019 and includes activities such as model design, demand model estimation, transport assignment, and software development.
| ANTONIN was commissioned and is owned by Île-de-France Mobilités, the authority responsible for public transport in the region. The first version of ANTONIN was created in the 1990s and the model has been continuously improved ever since. Significance has been involved in its development since the beginning. |
| ANTONIN is a comprehensive multi-modal transport model for the entire Île-de-France region (greater Paris). It integrates a custom demand model within the Cube software. This tour-based, disaggregated model distinguishes twelve travel purposes and includes various travel modes such as car driver, car passenger, motorbike, public transport (with access modes walk or drive), bicycle, and walking. Public transport path building and sub-mode choice, including train, metro, tram, and bus, are implemented in Cube. |
Key features of the updated model
| Demand Model Estimation: Ownership models for cars, public transport passes, and motorbikes; tour frequency models for twelve different travel purposes; and nested mode-destination choice models for each travel purpose. These were estimated using regional transport survey data (EGT). |
| Software Optimization: The demand models were implemented in custom software, optimizing calculation times by applying multi-threading and an efficient convergence method. The demand modules are integrated in the Cube software environment. |
| Public Transport Assignment: Extensive calibration and validation of sub-mode shares, number of public transport sub-modal trips, and elasticities of the public transport assignment model. This ensures accurate representation of public transport options and competition between lines and sub-modes. |
| Accessibility Measures: The composite cost option in Cube (similar to a logsum) is used to calculate accessibility measures in the assignment module, serving as input for the mode and destination choice module. |
This updated ANTONIN model provides a robust and efficient tool for planning and managing public transport investments in the Île-de-France region.
