Challenges and opportunities in building a centralized data science environment for the public transport industry [philipp.baumann@allianceswisspass.ch](mailto:philipp.baumann@allianceswisspass.ch)

https://allianceswisspass.ch --- ## Agenda - Why a centralized data science environment? Teams and roles - Infrastructure: deploy FLOSS-based services in Azure - Integrating full stack data science stacks and tooling --- ## Data Strategy

https://strategie.allianceswisspass.ch/main/ --- ## DSE Overview

--- ## ASP DSE Documentation

Access: Continuous work on integrating overarching data infrastructure and project tooling

--- ## Infrastructure as Code

Open-source infrastructure provisioning — used to manage compute, storage, and networking resources in the DSE. --- ## Centralized DSE:
Philosophy

The Data Science Environment (DSE) provides a centralized platform for data analysis, collaboration, and deployment at Alliance SwissPass. Each project receives its own set of resources all managed through infrastructure-as-code.

- Git repositories - CI/CD runners - Compute environments - Storage Containers --- ## Container-based CI/CD ```yaml when: - event: manual evaluate: 'task == "docs"' - event: pull_request - event: push branch: - ${CI_REPO_DEFAULT_BRANCH} steps: astro-build: image: docker.io/oven/bun:1-alpine pull: true commands: - bun install --frozen-lockfile - bun run build 'Move to host': image: docker.io/library/alpine:3.23 volumes: - /mnt/dse-doc:/mnt/dse-doc commands: - apk add -q --no-cache rsync - rsync -a dist/* /mnt/dse-doc/ when: - event: push branch: - ${CI_REPO_DEFAULT_BRANCH} ``` --- ## R and Python

### R Rich package ecosystem. Use for revenue distribution redesign. Embed python modules?

### Python uv and polars. Integrate container and storage access tools.

---

### Roles of Alliance SwissPass organization - Coordinate tariffs and regulations across all providers - Data role and analytics needs for projects at the headquarters: - Drive innovation (e.g., **myRIDE** pilot project) - Renovate Revenue distribution: flat-rate subscription (like General Season Ticket)

### Context - Industry body for Switzerland's entire public transport network - Multi-lingual (DE / FR / IT) - Strategic framework: **Strategie 2035**
