IVA project: modelling gives a boost to passenger information

What if passenger information were able to adapt to passenger behaviour and thus anticipate flows during traffic disruptions? That question led to the IVA project launched a few months ago.

SNCF Innovation & Research and Transilien have been working for three years on the modelling and interpretation of passenger behaviour during train service disruptions in the multipartner MIC project supported by the Technological Research Institute SystemX. “In this project, we have demonstrated the need to work more specifically on the impact of passenger information and the general outlines of passenger behaviour. We are going to dig more deeply into this subject with the IVA project – that stands for Augmented Passenger Information – which begins this autumn with Transilien as the client”, explains Sabine Tréfond, project leader at Innovation & Research.

A closer look at passenger behaviour

For this new project, SNCF has teamed up once again with SystemX and STIF as well as with IFSTTAR, a research institute specialised in transport, which will validate the largest share of the scientific and technical work (including two theses supervised by the IFSTTAR in the project). “For SNCF, the main objective is to construct a tool to model and simulate passenger behaviour during traffic disruptions. The project will be focused more specifically on anticipating the impact of passenger information on flows in order to determine the most suitable information scenarios.” Among the expected outputs of the project is the production of a system to allow the operator to visualise conditions on the network.
“Scheduled for between now and June 2021, the IVA project will really get underway in September with the analysis of ticketing data supplied by STIF to estimate, predict, and visualise indicators such as the delay, load, and other factors”, says Tréfond. “The study of behaviour will start early next year with the construction of a qualitative survey protocol.”
