本文试图通过分析行车间距与车速的关系 ,以新的理念和方法确定道路通行能力 .首先综合分析了行车间距的特征 ,内容包括安全间距和期望间距等 .前者取决于对安全程度的要求 ,后者则取决于驾驶员的行为特征 ,也可以说是交通流的模式 .安全间距和期望间距都是速度的函数 ,根据它们的曲线形状 ,可以找到二者的交叉点 ,这个交叉点就是道路通行能力值所在 ,它代表了满足最小安全度要求的最大流率
This paper attempts to determine the capacity of the road through new ideas and methods by analyzing the relationship between driving distance and speed.The first comprehensive analysis of the characteristics of driving distance, including the safety distance and expected spacing, etc. The former depends on the degree of safety requirements, the latter Depends on the driver’s behavioral characteristics, it can be said that the traffic flow model.Security spacing and the desired spacing are a function of speed, according to their shape of the curve, you can find the intersection of the two, the intersection is the road traffic The ability value is where it represents the maximum flow rate that meets the minimum safety requirements
