From the perspective of traffic safety, interactions between cars, bicyclists and pedestrians that lead to crashes comprise the largest part of all crashes. One major cause is missing or inadequate communication. This results in inadequate understanding and anticipation of what the other is going to do. Additionally, communication could further cooperation which leads to positive emotions and a better traffic climate. Within the project KOLA (Kooperativer Laserscheinwerfer; cooperative laser beam), we first examined needs in traffic which lead to positive emotions (positive arousal, being thrilled and feeling close to others) when fulfilled, and negative, if denied (being irritated, annoyed, horrified and feeling hostility). With regard to communication messages, explaining one’s intentions and actions and thanking others was identified as the most relevant topics. Prototypical messages were designed and evaluated in two driving simulator studies using light which was projected from a car as the medium of the messages. We found that expressing one’s intention in a specific situation furthers understanding and prosocial behavior of others, which leads to positive emotions on both sides. Explaining one’s unusual behavior works similarly to increase understanding and further positive emotions but seems to require specific information about the causes of the behavior. Enabling drivers to thank others encourages prosocial behavior and leads to positive emotions. Thus, light-based communication is an excellent way to further communication, cooperation and positive emotions in traffic. The studies presented provide a sound starting point for further research and development.
