Abstract
In recent years, there are many game genres called open world racing games. In this game genre, it is a racing game with the feature that you can explore a vast map and race and time attack in various places. In this game genre, there are general vehicles that run according to the traffic rules in the game. The traffic flow formed by general vehicles is different from the traffic flow formed by automobiles in the real world, and there is no difference in traffic flow between developed cities and rural towns. There is a problem that the traffic flow does not change according to the change of the map environment, so it cannot play a role as a part of the landscape. Also, by assuming multiplayer, it is difficult to make adjustments by simply adding or deleting general vehicles because there are multiple players’ fields of vision. Therefore, In this research, we aim to propose a traffic flow adjustment method for general vehicles considering the visibility of multiple players.
