Empowering Multimodal and Intermodal Accessibility Analysis

Within the project EMMA, we are building a multimodal and intermodal accessibility model for workplace locations in the metropolitain region of Munich, enabling new analysis that will contribute to a better regional understanding and planning of workplace locations and their impacts on the daily commute of its workers.

EMMA is a DFG-funded project at the Chair of Urban Structure & Transport Planning at Technical University of Munich. It is part of the Research Group Accessibility Planning at the Chair.

Our Accessibility Model

The model is multimodal in a sense that we look at the most important modes of transport in parallel (Public Transport, driving, cycling, and walking). It is also intermodal, because our methodology allows the analysis of combined trips, such as Bike&Ride, which play an increasingly important role in times of the intruduction of new mobility services that aim at complementing public transport rather than replacing it.

Tools & Data

EMMA is built 100% on open source tools. We use

  • OpenTripPlanner for routing and isochrone calculations
  • PostGIS to store and query our spatial data
  • R & RStudio for scripting, data analysis, and putting it all together.

Open data is the foundation of our analysis. Mainly
