Abstract
This paper describes a design of a riding simulator for two wheeled vehicles which is used to analyze the human factor of riders. In order to construct the simulator, the relationship between the movement of the rider and behavior of the two wheeled vehicle is inquired with experiments on a proving ground. Based on the results, we produce the simulator system and construct the algorithm. Then, we conduct several ratings to validate and examine the simulator which is constructed. From the results, it is shown that the simulator possesses high utility for analysis of human factor of a rider.
