文中选取北京市西直门换乘枢纽站内一条换乘通道作为研究对象,通过人工采集通道的相关数据,经整理计算,绘制出流量—空间关系图。在此基础上,利用元胞自动机模型进行该通道的计算机微观模拟,将得到的模拟结果与实测数据进行比较,有较大差异。通过调整原模型中的行人速度判断环节并重新模拟,将重新模拟得出的流量—空间关系与实测结果作比较,发现有较好的相似性。
In this paper, a transfer channel in Xizhimen Interchange Terminal in Beijing is selected as the research object. Through the data collected by the artificial channel, the traffic-space relation is drawn through the collation and calculation. On this basis, the use of cellular automata model for the channel of computer micro-simulation, the simulation results obtained are compared with the measured data, there is a big difference. By adjusting the pedestrian velocity in the original model and re-simulating the link, the simulated flow-space relationship is compared with the measured results to find a good similarity.
