摘要

高速公路的反复拥堵是城市交通系统中造成交通拥堵的主要原因，而合并路段是高速公路上拥堵最严重的路段。由于科技大学场地存在严重的拥堵，本研究旨在发现该场地的交通特征，以确定适当的解决方案。因此，本研究选择Mohammed Al-Qassim高速公路上的一段合并路段，研究伊拉克这段合并路段的一些特点。从这个地点收集了4小时的现场数据。这些数据是通过安装在巴格达市高速公路沿线的摄像机收集的，这条高速公路被称为Mohammed Al-Qassim高速公路。这些数据显示了上游和坡道的流量。采用先进的城市和非城市网络交互微观模拟器(AIMSUN)程序，对当前情况下难以获得的其他特征，如速度和占用率进行了研究。结果表明，模拟数据与实际数据吻合较好。在本研究中，AIMSUN程序通过使用Geoffrey E. Havers在交通工程、交通预测和交通建模中使用的两组交通量比较方法获得认可，并通过增加匝道计量和循环(绿)时间控制来加强道路管理。

Investigating traffic characteristics for merging sections in Iraq

Abstract Recurring congestion on highways is the primary cause of traffic congestion in the urban traffic system while jams on merging sections are the worst section along the expressway. Due to the presence of heavy congestion in the site of University of Technology, this study aims to discover the traffic characteristics of this site to determine the appropriate solutions. Therefore, this study selects a merging section on Mohammed Al-Qassim expressway to investigate some characteristics of such a section in Iraq. Field data have been collected from this site for 4 h. The data were collected from video cameras installed along the expressway in Baghdad city which is called Mohammed Al-Qassim Expressway. These data present flow of upstream and ramp. The Advanced Interactive Microscopic Simulator for Urban and Non-Urban Networks (AIMSUN) program was also adopted to investigate other characteristics which are difficult to get such as speed and occupancy for the current case. The results showed that the simulated and real data significantly corresponded. In this study, the AIMSUN program received recognition by utilizing Geoffrey E. Havers a method for comparing two sets of traffic volumes that are used in traffic engineering, traffic forecasting, and traffic modeling as it was discovered to be comparable to reality, and the road management was then enhanced by the addition of ramp metering and cycle (green) time control.
