基于道路安全评价的协同震荡模型研究

为了评价道路的安全性,运用高等协同学、种群动力学、系统工程学等理论,从汽车在不同的道路环境中行车时驾驶员心理-生理感受出发,借助动态的心理-生理检测设备,在大量的行车实验数据基础上,结合驾驶员的舒适性阈值,根据人、车、路、环境等交通因子对驾驶员心理反应程度影响,构建评价道路安全的协同振荡模型,并结合实际事例对模型进行了验证,运用协同振荡模型从驾驶员舒适性角度对我国山区双车道公路的安全性进行评价,同时提出了道路的改建措施.

The Study of Synergetic-fluctuation Model Based on Road Safety Assessment

In order to evaluate the level of road safety, this paper proposes a synergetic-fluctuating model which is derived from theories of higher Synergetics, population dynamics, and system analysis engineering. In this study, a great deal of field survey data is obtained via a set of physiological and psychological detection devices. By analyzing data combined with driving comfort threshold, a synergetic-fluctuating model is founded according to different effects, caused by traffic factors such as people, vehicles, roads, and environments which are imposed to drivers and induce various psychological responses to drivers. In addition, a real case study, which is maele on the proposed model to evaluate the safety level of mountain two-lane road in China, is presented. Through the case study the rationality and applicability of the model is validated. Thus a new research method for traffic safety and the further measures of improving road safety are provided.
