Empowering Multimodal and Intermodal Accessibility Analysis //

Ein multi- und intermodales Erreichbarkeits modell für Arbeitsstandorte

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

First results

Our first results from a data analysis of 996 workers who have changed their workplace location while maintaining the same residential locations provide evidence that the workplace location alone has a huge impact on the modes used on the daily commute, as well as on the car ownership of workers. This emphasizes the importance of workplace locations and their accessibility, while demanding further investigations on the accessibility of these locations in order to create knowledge that will help planners and decision-makers to plan better accessible workplace locations than foster sustainability.

Current status & next steps

The project runs from January 2019 to December 2021, so currently we are right in the middle of the project. A first paper about our data analysis will be published soon, a second one about the methodological concept of the accessibility model will follow.
The focus in the last project phase starting in January 2021 will be the application of the model and its policy implications.

EMMA's conference presentations this summer

During the summer, we had the chance to present EMMA at two wonderful online conferences. While most in-person events have been cancelled during the COVID-19 pandemic, these virtual events are a great way to ensure fruitful discussions and collect feedback, which is crucial for all kinds of research.

Temporal accessibility of workplaces by time of day

The release of the official nation-wide GTFS dataset for Germany has been a game changer for all kinds of public transport analysis recently. Within EMMA, we use a filtered version of this dataset for the region in OpenTripPlanner.

First EMMA workshop at TUM

December 10, 2019 was a special day for Maximilian Pfertner’s PhD project EMMA – “Empowering Multimodal and Intermodal Accessibility Analysis”: Seven international experts joined us for the first expert workshop within our project funded by Deutsche Forschungsgemeinschaft (DFG) - German Research Foundation.
