曲线组合是一种常见又比较复杂的道路线形组合形式之一。符合设计标准的平、纵组合路段线形指标是驾驶员安全行驶的保障。因草原特殊的地形特点，其公路平、纵面线形的技术指标大小不均衡，影响了其线形的平顺性，使曲线组合成为草原道路行车的一个不舒适和不安全点。本文采用时、频域相结合的研究方法，对草原公路曲线组合段驾驶员心率变异特性进行研究。驾驶员在实验曲线组合路段行驶时，其心率变异指标也呈现不同变化规律。本文通过比较驾驶员在曲线组合路段时、频域指标得出：时域分析方法较频域分析方法更适于对驾驶员在曲线组合路段心率变异性的分析。本文初步探讨了不同曲线组合路段对驾驶员的疲劳影响，期望能为草原公路设计者提供有价值的理论依据，以提高草原公路的交通安全水平。

Curve combination is a common but complex form of road linear combination. The standard that meets the flat, vertical road linear combination is the guarantee for drivers. Grassland highway curve combination has an uncomfortable and unsafe point because of the uneven level and longitudinal linear combination indicators and its special topographical features. The article obtains the law that the heart rate variability indexes are in different sections of grassland highway curves through studying the method of time domain and frequency domain combining. Meanwhile, the article gets the conclusion that the time domain analysis method is more suitable to drivers than the frequency domain analysis approach. Preliminary, the studies is about influence of fatigue driving on the Grassland highway curve combination. It hopes to provide valuable theoretical basis for designers of grassland highway, which can improve traffic safety level.
