The Modus project addresses the topic SESAR-ER4-10-2019 "ATM Role in Intermodal Transport". The main objective is the analysis of the performance of the overall transport system by considering the entire door-to-door journey holistically, and assessing the role of air transport within an integrated, intermodal approach. For this purpose, Modus identifies and assesses (future) drivers for passenger demand and supply of mobility in terms of their impact on passenger mode choice. This enables the development of multiple scenarios of future mobility paths, taking into account aspects such as new regulatory contexts meeting new environmental standards, or new transport operators' business models, covering a time horizon of 2030+.

An integrated modelling approach which includes the development of data-driven models of air and ground passenger transport in Europe is implemented to assess the impact across these scenario on airside and landside processes and capacities. This provides detailed insight in the impact a complementary intermodal alignment or competition may have on the air transport sector.

Using this insight into and modelling results of the future transport system, both quantitative as well as qualitative analyses, including a set of performance and connectivity indicators with specific business and operational targets and constraints, are applied to identify and assess the main gaps and barriers in achieving European (air) mobility goals. Based on these analyses, potential solutions in regard to processes, technologies and changes required to meet high-level European transport objectives are proposed, including, for example, recommending ways how air transport can evolve by efficiently connecting information and services with other transport modes to achieve the e.g. 4 hours door-to-door goal.
