Pedestrian Interventions

Our project aims to recover a city designed for people, and not for cars. To achieve that, we started redesigning the public space and recovering the spaces that had been won by the car to be used by people now.

As far as a walkability plan is concerned, we put the pedestrians in the centre, and we try to give them the necessary protection to enjoy walking the city.

The aim of the Pedestrian Interventions is to change the design of the intersections to achieve a better organization of pedestrian and vehicular flows revaluing the streets of the City. The goal is to create a friendly and safe environment for pedestrians.

The design of these interventions is based on different concepts of urban planning. On the one hand, they take into account the interpretation of the desire lines at intersections or complicated corners. The pedestrian desire lines refer to the roads that lead you more directly to your destination. On the other hand, interventions incorporate elements of traffic calming.

Traffic calming strategies consist of the design and incorporation of elements (road narrowing, roundabouts, traffic islands, etc.) aimed at reducing vehicle speeds, which increase safety for pedestrians and cyclists.

The design of the intervention in turn is the result of the analyses of the conflicts and opportunities that occur at intersections. Specifically, we analyze where pedestrians cross, if the desire lines are respected, if they wait on the street or on the sidewalk and if they are visible to motorists. In turn, untapped spaces - excess asphalt- are detected to be recovered for pedestrians.

This approach would create shorter and visible crosswalks, which reduce the exposure time of pedestrians and the risk situations. It facilitates the reading of the intersection both for pedestrians and for drivers.


This type of intervention is done with reflective painting, recreating a different road to vehicular space. The new pedestrian areas, in turn, are marked with double white line for delimitation, flexible and reflective delineators and also reflective and solar studs.

In all these cases, new crosswalks are painted and existing crosswalks are enlarged following the pedestrian desire lines. These works incorporate vertical and horizontal signage, planters and street furniture.

The materials used have a fast and low cost implementation. The Interventions transform the space in an innovative and more efficient manner, without the need of large infrastructure projects.

The Interventions are located in three different areas of the city and they are organized in four different axes.

Citizen input

Once the project was finished, we carried out a survey to find out the general opinion. As a result, we fund a positive evolution with respect to the change produced by the interventions. The majority of pedestrians indicated that they are more safe crossing the street, and they noticed that the space is more friendly now. Finally, they expressed an interest on more of these types of interventions.
