Short abstract:

Tracing data journeys in the context of traffic transformation in Frankfurt, we explore the intricate data supply chains involving municipality, enterprises, and citizens. We examine the multifaceted roles those actors obtain in data trading, shedding light on forms of data valorization at play.

Long abstract:

Urban traffic infrastructure matters for a variety of actors: the municipal administration, private enterprises, and most numerously, citizens. Just as manifold as the relations between these actors are the traffic data they generate for different purposes at different locations, and the evolving supply chains.

This presentation is based on an ongoing research project on data politics in the proclaimed “sustainable traffic transformation” (Verkehrswende) of Frankfurt, Germany. We use the concept of data journeys (Bates et al. 2016) to trace how data is produced, processed, and shared within the complex networks at play.

Many actors obtain ambivalent roles in this entanglement: Citizens are simultaneously customers, objects of datafication, data consumers, or sometimes even data manufacturers, while the municipality acts as both a key data provider and a customer. In addition, relevant legal regulations and political interests contribute to a mixture of commodification logics and practices. As a public actor within private markets, the municipality finds itself in various double binds.

We will illustrate the diversity of data trading practices on two examples. While the data purchases involved in the development of a new municipal traffic model follow traditional logics of marketization, other constellations elude those. In the case of pedestrian counters that were installed in Frankfurt, the agreements are based on an exchange of various services and mutual data provision instead of monetary payments. Attending to those diverse forms of bargain allows us to investigate the multifaceted practices of data valorization involved along different stages of the supply chains.
