A personal project for more sustainable car tips.

The problem

How can we make private car trips more sustainable in Barcelona? Each day 1,140,490 private cars enter and leave the city. Many of those vehicles have one single occupant and will keep driving despite traffic restrictions.

Drivers don’t want to waste time. Drivers and locals take the private vehicle to go to areas where train, bus or subway takes twice as much as the car. Although thoses drivers know the mobility apps, they prefer the private car for ease.


A collaborative mobile application for the Barcelona metropolitan area. A platform where you pay a fair to share everyday car trips.

My role

It was a personal project. Based on the user analysis, I knew that we had a problem and it was necessary to design a solution that was easy to use.


These are the tools I used for design and validation.




By gathering the experiences, I defined one persona that represented the highlights of a user with both passenger and driver profiles.

Draw It

The home screen allows you to search by address or, by clicking on the location icon, enter the map and draw the area of influence. Map search, Google maps API, integrates the ability to draw an area of influence, where the app will calculate a central point to enter an approximate postal address.

The app calculates the areas of influence of other users to facilitate collaborative use based on the area drawn. The steps are repeated for the destination area. We also complete periodicity details. The role that the user plays in this trip will determine the following navigation steps.

However, if the user configures a trip as a driver, the trip will simply be stored and he will not receive any more warnings until he is notified that someone has contacted him.
