This paper focuses on Vietnam and Thailand, where traffic safety has become a problem due to the rapid increase in the number of motorcycles, and describes local surveys that were performed to study issues relating to traffic accidents and safety for which there are insufficient statistical materials. The problems that were identified by the surveys included those of excess speed, operation of motorcycles in excess of riding capacity and non-usage of helmets. The dynamic characteristics of motorcycles when operated in excess of riding capacity have not been the focus of previous studies, since the non-linear characteristics of this problem are not ideally suited to model-based calculation. Consequently, this paper describes data related to braking and steering characteristics obtained in actual vehicle tests in this state. These results are then used to form proposals for educating riders about safe riding in line with local conditions of motorcycle usage.

The educational systems for driving vehicle are recently progressing every year like aircraft simulator. To know the learning process of training are very important for designing total education system. Therefore this research considers the methodologies of measuring human learning process when the beginner rider practicing by using motorcycle simulator. Here, a motorcycle needs the proper manipulating practice in the event of first riding because the manipulation use both hands and feet with keeping balance. For this reason in this paper it is considered the methodologies of measuring rider learning effectiveness by recording rider behavior and motorcycle movement.

1 Generally speaking, it is considered that the motorcyclist's mental stress is kept higher than driver's, because two-wheeled vehicle is emphasized it's disadvantageous to the people. But the authors had doubts about reliability. And for finding out the original sources of motorcyclist's mental stress, and the simplified running courses are set up and experimental research of motorcyclist's mental stress is performed. On the other hand, the experiments with the driver of four-wheeled vehicle are made also in the same way, and mutual comparisons are made. Consequently, it is found that motorcyclist's mental stress is lower than driver's in some situations. Especially, in the situation of leading the vehicle along the course, it is found that motorcyclist's mental stress is kept lower than driver's.
