In our daily lives, we often have to face binary decisions where we seek to take the minority's choice, e.g., in traffic scenarios where we have to choose between similar alternative routes. We have studied agent coordination mechanisms in a binary decision model introduced in the literature recently: the Minority Game. Extending this model, we have introduced personalities, which model certain types of human behavior. Different populations of these personalities have been simulated. It was found that there is one personality, which performs better than the average: the wayward personality. We have also extended the concept of Hamming distance (a standard probabilistic measure for the difference between strategies) to account for our personalities; this notion is useful for qualitatively explaining or predicting results. Our work gives insights into the impact of commuters' behaviors and it addresses relegated issues in traditional traffic simulation.
