Pilot för validering av nya datakällor för skattning av kollektivtrafikruttval (VaNDKoll)

Pilot for validation of new data sources for public transport route choice estimation

This pilot study aims at investigating both appropriate data and methods that will be used to estimate a route choice model for public transport. The project will mainly utilize two types of data, namely the travel diary data from the mobile app TRavelVU (Berggren et al., 2021) and SL Access-card data (Cats et al., 2019). SL Access-card data have a good representativeness of passenger travel flow and route choices but lack the information of access-egress trip legs. This project thus will develop method for modelling of access-egress trip legs with the help of TRavelVU data. The “complete” route observations with access/egress legs can be developed and used in the estimation of public transport route choice. The estimation results are expected to provide the preference parameters that can be used in the public transport assignment that in the current situation does not have a solid scientific ground. The estimated preference parameters will hopefully give more realistic passenger flow distributions between lines at certain stations/stops. The pilot study will serve as a base for the eventual PhD project that will evaluate the methodology developed in the pilot study and scale it up to the implementation in e.g. the Sampers SAMM model.
