Route choice refers to the decision-making process that individuals undergo when selecting a specific path or route to reach a desired destination. This research area is focused on understanding the factors that influence people's decision-making when it comes to selecting a route, such as cost, travel time, congestion, safety, and personal preferences. Researchers in this field may use various mathematical models, behavioral studies, and data analytics to study and predict route choice behavior, with the ultimate goal of optimizing transportation systems and infrastructure to improve efficiency and reduce congestion. Additionally, route choice research may also examine the impact of new technologies, such as GPS navigation systems and real-time traffic updates, on decision-making processes.
