Abstract
Recently, the number of traffic accidents is decreasing due to the development of safety technologies. However, it is difficult to select an appropriate speed to pass the unsignalized intersection without a regulation stop sign for elderly person. To support such drivers, this study aims to construct an expert driver model based on risk potential field. First, driving data of expert drivers are acquired by the experiment in the public road. Next, by optimizing the parameters of risk potential function in the framework of an optimal theory, the velocity profile of the expert driver can be estimated. Finally, the feasibility of the proposed model is verified by comparing the simulation results with the actual driving data by expert drivers.
