CH on the move: Introducing the Prototype Digital Twin of The Swiss Mobility System

Abstract

Mobility simulations are crucial for research, industry, and governance. However, sim- ulating mobility systems with reasonable accuracy requires large-scale efforts of data collection, data transformation, data analysis, and data visualization. The paradigm of the digital twin offers a novel perspective on how to manage the data efficiently and make the simulations available more steadily at a lower cost. We introduce the first prototype of the “CH on the move” digital twin that is designed to be openly available to all interested parties to enable a common baseline for transport research in Switzerland. This digital twin is based on the extensible Open Digital Twin Platform (ODTP) that uses containerization, loose coupling, and micro-services to provide dynamically composable digital twins. In its first iteration, “CH on the move” provides an easy-to-use version of the eqasim pipeline for MATSim making it possible to initiate simulations of Switzerland with one click. Future versions of “CH on the move” aim to include a rich set of relevant data sources and analytical pipelines related to transport and mobility and make them easily accessible to research, industry, and governance.
