| 摘 要： | 为了分析车队离散模型在实际中的适用性,首先剖析Roberston模型存在的不足,考虑左转影响下车队的离散特性,建立左转影响下直行车的离散模型.以北京市调查数据为基础,利用实际数据对离散模型进行验证,结果表明,A取0.1与实际数据比较吻合,左转影响下的离散模型预测的效果更佳.

| Abstract: | To analyze the applicability of the platoon discrete model in practice, Roberston＇s platoon discrete model was dissected to discover the deficiencies. Considering the influence of the left turning, a new straight pla toon discrete model was established based on the characteristic of platoon discrete. The new platoon discrete model and discrete coefficient were validated by the traffic flow actual investigation data in Beijing city. It is proved that discrete coefficient A equal to 0.1 matches the actual data better and the established model is char acterized by better predictive effect. |
