一般来说，新手驾驶员在不熟悉的交通环境中驾驶往往会感到不安。日本于2011年11月修订了道路交通法。该修订授权了环形交叉口的运营，这是一个无交通灯的交叉口。环形交叉口在欧洲已经得到了广泛的应用，而日本人对环形交叉口并不熟悉，尤其是新手驾驶者容易产生恐慌。因此，本文的目的是驾驶行为建模，以支持操作的新手司机。此外，我们还研究了新手驾驶员在环形交叉口的导航效果。首先，使用UC-win/Road构建了环形交叉路口的驾驶模拟环境，收集了新手驾驶员在有导航和无导航的情况下的驾驶日志。然后，我们将驾驶日志分类为一些离散的驾驶状态（即，基于高斯混合模型（GMM）的离散驾驶状态（直行）模型，绘制离散驾驶状态的状态转移图，对驾驶员行为进行建模。通过上述方法得到的驾驶员模型在仿真环境中反映了新手驾驶员的驾驶行为特征。
Generally, novice drivers often feel uneasy about driving in unfamiliar traffic environment. In Japan, the road traffic act was revised in November, 2011. This revision authorized the operation of the roundabout intersection which is a traffic-lights-free intersection. The roundabout intersection have been widely spread in Europe, on the other hand, Japanese people are unfamiliar with the roundabout intersection, and especially novice drivers may panic easily. Thus, this paper aims for modeling driving behaviors to support operation of novice drivers. Moreover, we examine the effects of navigation at the roundabout intersection for the novice drivers. First, we built a driving simulation environment for roundabout intersection by using UC-win/Road, and we collect driving logs of a novice driver who drives with navigation or without navigation. Then, we classify the driving log into some discrete driving states (i.e., go straights) on the basis of Gaussian Mixture Model (GMM) and plot state transition graphs of the discrete driving states to model driver's behavior. The driver model obtained by above method showed the characteristic driving behaviors of novice drivers in the simulation environment.
