Abstract
In this paper, we have represented a fundamental framework of a decision making model focusing on consecutive information reference processes under multiple information sources. The information value having been evaluated with the conventional aspect of behavior profits is formulated by regarding the information value as a variation for the maximum opportunity loss of expectation from the aspect of decreased uncertainty in decision making. Furthermore, a consecutive information reference model and a route model considering information reference processes are presented; thus the case study was conducted using actual behavior data. As a result of the model estimation, we have found that the drivers who have higher uncertainty in decision making tend to have more opportunity to refer to the traffic information and that such uncertainty in decision making is considerably reduced upon the provision of multiple information sources.
