This study discusses capacity of weaving sections based on several observations on the Metropolitan Expressway. The study is divided into two parts : a macroscopic analysis of traffic flow conditions such as flow, speed, and density of traffic in a weaving section, and a microscopic analysis of each vehicle motion in order to develop a simulation model which can reproduce weaving capacity.For the macroscopic analysis, we first show that capacities of some weaving sections are lower than those of simple section by at most 26% and that the capacities vary depending on highway geometry and traffic conditions such as weaving lengths and volume ratios. Secondly, we compare values of weaving influence factor estimated by the 1965-HCM (Highway Capacity Manual) with the observed values. The estimates were found to be slightly smaller than the observed values. Thirdly, we examine applicability of four different existing methods for predicting weaving speed ; those are the 1985-HCM, JHK, PINY, a … More nd Leisch methods. The 1985-HCM method gives the best agreement with the observed speed but the PINY and Leisch methods tend to underestimate the speed.For the microscopic analysis, using vehicle trajectory data obtained from observations, microscopic variables such as relative position and relative speed of weaving vehicles are analyzed. Based on these data, a simulation model estimating weaving capacity was developed. It is considered that weaving vehicles are always selecting an optimum acceleration and the required time for lane changing corresponding to the aimed gap, and they adjust these variables until the weaving is completed. In this model, every vehicle momentarily updates such particular maneuvers precisely by predicting its condition at the moment the weaving is completed. The simulation model was validated at two congested weaving sections on the Metropolitan Expressway. As a result, the simulated values f capacity and speed fit well with the observed ones. Finally capacities at the weaving sections under various traffic and geometric conditions were discussed. Less

本研究根据对首都高速公路的多项观察，讨论了编织路段的容量。该研究分为两部分：宏观分析交通流条件，如迂回路段的流量、速度和交通密度，以及对每个车辆运动的微观分析，以开发能够重现迂回通行能力的模拟模型。对于宏观分析，我们首先表明一些迂回路段的通行能力比简单路段的通行能力最多低26%，并且通行能力根据高速公路而变化。 几何形状和交通条件，例如编织长度和体积比。其次，我们将1965-HCM（公路容量手册）估计的编织影响因子值与观测值进行比较。发现估计值略小于观测值。第三，我们研究了四种不同的现有方法用于预测编织速度的适用性；这些是 1985-HCM、JHK、PINY、a … More 和 Leisch 方法。 1985-HCM方法与观测速度的一致性最好，但PINY和Leisch方法往往会低估速度。在微观分析中，利用观测获得的车辆轨迹数据，分析了编织车辆的相对位置和相对速度等微观变量。基于这些数据，开发了估计编织能力的模拟模型。认为迂回车辆总是选择与目标间隙相对应的最佳加速度和换道所需时间，并调整这些变量直到完成迂回。在该模型中，每辆车通过预测其在编织完成时的状况来精确地即时更新此类特定操作。该仿真模型在首都高速公路的两个拥堵的编织路段进行了验证。因此，容量和速度的模拟值与观测值非常吻合。最后讨论了不同交通和几何条件下织造部分的容量。较少的
