Process-Oriented Dynamic Route Choice Model

The deliberation process is rarely considered in conventional route choice models.In this paper,the decision field theory (DFT) is used as the theoretical basis to develop a framework and to model the process-oriented vehicle dynamic route choice.The interactions of driver psychology,road conditions,and decision-making time are taken into account,and the travel time,distance,as well as the number of intersections are set as the main attributes in the model.In this way,the model is closer to the actual decision-making process.The model simulation results show that incomplete traffic information leads to "certainty effect",and cannot guide the driver effectively.The drivers' route choice decisions and processes depend on the drivers' characteristics,uncertainty of road conditions,as well as the time pressure which reduces quality of decision-making and cause "reversal phenomenon".
