车头间距分布规律的研究

Study on the Distribution Patterns of Time Headway of Vehicles

摘要: 以我国混合车流作为高等级公路交通流的基本构成,分析了混合车流车型跟驶序列组合的概率;采用计算机模拟手段,得到了车头时距阈值与速度关系、不同跟车序列最小车头间距、车头间距与随机度关系和车头间距与流量关系;并通过随机度参数将微观和宏观参数整合为一体。以我国混合车流作为高等级公路交通流的基本构成,分析了混合车流车型跟驶序列组合的概率;采用计算机模拟手段,得到了车头时距阈值与速度关系、不同跟车序列最小车头间距、车头间距与随机度关系和车头间距与流量关系;并通过随机度参数将微观和宏观参数整合为一体。

Abstract: Taken mixed traffic flows as the basic constitution of high ways, the combinatorial probability of following sequences of mixed traffic flows is analyzed. The relationship between vehicle speeds and the maximumtime headway and that between the minimum time headway and randomness of traffic flows are obtained. Then the macro-parameters are integrated with the micro-parameters through randomness of traffic flows.
