Work zones widely exist on urban roads in many countries and have a significant negative impact on traffic. Few studies have focused on modeling the traffic flow of the work zone on the urban arterials, especially on the work zone at the intersections. In this paper, a microscopic model based on the social force theory for the traffic flow of the intersection with a specific work zone, called straddling work zone, is proposed. The model can capture the no lane division and irregular boundary characteristics of the traffic of the intersection with a straddling work zone and also can reflect the interaction of the intersection traffic flows from the two opposite directions. The proposed model is calibrated and validated using the real work zone data, and the results display that the MARE values are all less than 10%. The factors affecting the traffic flow in the straddling work zone are analyzed through simulation. Our study reveals that the distance from the lower edge of the work zone to the median divider of the road and the proportion of large vehicles in the work zone have the greatest impact on the signalized intersection, which provides a reference for the future traffic control at the intersection with the straddling work zone.

跨工作区的城市信号交叉口交通流建模

在许多国家，工作区广泛存在于城市道路上，并对交通产生严重的负面影响。很少有研究集中于对城市干线上工作区的交通流量进行建模，尤其是在交叉路口的工作区。本文提出了一种基于社会力量理论的微观模型，该模型用于交叉路口与特定工作区的交通流，即跨界工作区。该模型可以捕获交叉工作区交叉口交通的无车道划分和不规则边界特征，还可以反映来自两个相反方向的交叉路口交通流的相互作用。使用实际工作区数据对提出的模型进行校准和验证，结果显示MARE值均小于10％。通过仿真分析了影响跨工作区交通流量的因素。我们的研究表明，从工作区下边缘到道路中间分隔线的距离以及工作区中大型车辆的比例对信号交叉口的影响最大，这为将来的交通控制提供了参考与跨工作区的交叉点。
