From “streets for traffic” to “streets for people”

Can street experiments transform urban mobility?

Despite their growing application and worldwide diffusion, the transformative potential of experiments aimed at achieving “streets for people” rather than “streets for traffic” remains largely under researched. There is little to no comparative assessment of already existing experiments, and no critical reflection on their specific added value for systemic change.

Building from a literature review and discussion, this paper aims to fill this gap by addressing the following questions: Which types of city street experiments have been undertaken in the pursuit of the vision of “streets for people” instead of “streets for traffic”? What are their backgrounds, main characteristics, and reported impacts? And perhaps most importantly: How can these city street experiments trigger systemic change in urban mobility?

These elements are detailed per experiment type, in order of ascending functional complexity: the re-marking of streets, the re-purposing of car parking, the re-purposing of sections of streets, and the repurposing of entire streets. Illustrative examples from practice include intersection repairs, parklets, the pavement to plazas programme, play streets, ciclovias and open streets.

The reviewed literature documents positive impacts on physical activity, active transportation, safety and social interaction and capital, and more mixed impacts on business activity. While street experiments aim to create fundamentally different arrangements of urban mobility, their potential as triggers of a greater systemic change is unclear.

This paper uses the defining characteristics of “transition experiments” – a concept derived from the field of transition studies – to develop and illustrate a framework to assess this transformative potential. In the conclusions, the review and assessment framework are used to sketch a research and policy agenda for this increasingly topical phenomenon.
