Traffic accidents are the leading cause of death among young Mexican people. The crosses on the road serve as a reminder of a fatal accident and are clear evidence of a problem. On November 2nd, these crosses were intervened with handmade traffic signs made with the same craft as traditional “Day of the Dead”offerings. Using data analysis, we detected the areas with the highest rate of accidents, we located the crossroads in their surroundings, and we placed the signs to leave a warning message for everyone to see.
