摘　　要：为解决车道变换行为对道路通行能力影响的定量分析难题,从观测数据的整理分析结果出发,揭示了车道变换行为与交通流流率的关系。定性分析车道变换行为和交通量的关系,发现当交通量过大或过小时,车道变换行为发生的概率较低,当交通量适中时,车道变换行为发生的概率最大。基于道路通行能力和道路空间占有率的关系,提出车道变换行为对道路空间额外占有度的计算方法,构建了车道变换行为对道路通行能力的影响模型,并进行参数标定。提出车道变换行为对道路通行能力影响修正系数的计算方法,最后以两车道和三车道为例进行修正系数的计算方法,并给出应用案例。To solve the problems of quantitative analysis the impact of lane-changing to traffic capacity, based on the analysis of observation data, revealed the relationship between lane-changing behavior and traffic capacity, found that when heavy or mild traffic, the probability of lane-changing behavior occurrence was low, moderate traffic when the lane-changing situation, the probability of occurrence of acts was greatest. Based on the relationship between traffic capacity and the share of road space, put forward a calculated method and model of lane-changing about it’s effected to additional road space, and calibrated the parameters, the correction factor is calculated. At last, two-lane and three-lane road as an example for the correction factor was calculated, and given an application of the case.
