集装箱码头堆场道路交通的瓶颈往往在道路交叉口处,对交叉口交通状况进行仿真研究能够更加细致地发现道路规划中的问题。建立了规划中的中国某大型集装箱码头堆场的整体仿真模型,结合交叉口道路通行能力计算,辅助该码头堆场的道路规划。给出了模型的流程,通过仿真实验,获取高峰期瓶颈交叉口交通流量数据,与计算得到的信号控制下和无信号控制下的交叉口通行能力进行比对,发现无信号控制交叉口不能满足交通流量需求,对原始道路设计方案提出设置智能化全感应信号控制交叉口等改进建议,并验证了改进建议的有效性。
The bottlenecks of road traffic at container terminal yards are often found at road intersections. Simulation studies on the traffic conditions at intersections can identify problems in road planning more carefully. The overall simulation model of a planned large-scale container terminal yard in China is set up, and the traffic capacity at the intersection is calculated to assist the road planning of the terminal yard. The flow of the model is given. Through the simulation experiments, the traffic flow data at the bottleneck intersection are obtained, and compared with the calculated signal control and the traffic capacity under the no signal control, it is found that the signalized intersection can not be satisfied Traffic flow demand, the proposed design of the original road intelligent all-induction signal control intersection and other improvements, and verify the effectiveness of the proposed improvements.
