Abstract
We have proposed an instruction system for improving the parking operation by elderly drivers with the use of the trajectory of each driver at a parking lot. Experiments on the evaluation of the system with 18 elderly drivers were conducted. The results of comparison between the trajectories before and after the instruction show that the average precision of parking trajectories was improved. In addition, with questionnaire on the system concept, the use fee, the impression and so on, we classified the drivers into several classes by the method of the standardized driving style questionnaire. Results of the experiments and questionnaire show that the gender, a driving style, and use fee are the factors much influencing the proposed system.
