Improving cleanliness in Metro and RER stations

The RATP wants to improve passenger satisfaction and optimize cleaning costs.The nudge approach based on the analysis of behavioral biases made it possible to identify several solutions to softly nudge passengers to change their behavior. Okoni designed, made, and installed the prototypes in three metro stations and one RER station for experimentation.The nudges use different mechanisms: gratification, the salience of places and equipment, the principle of reciprocity, ease of use, social norms, etc.

Results
