摘要:
针对常用的公路交通流车速-流量关系模型不能进行交通流超饱和状态下交通分析的不足,本文首先应用大量的交通观测数据建立了各级公路车速-流量关系理论模型,通过对公路高峰小时超饱和状态下交通流消散过程的机理分析,研究了各级公路在不同交通负荷条件下的车速-流量关系通用模型的结构,并通过与大量观测数据的拟合,建立了各级公路在任何交通负荷条件下的车速-流量关系通用模型的函数表达式,提出了各级公路在不同设计车速下的实用模型参数.该模型成功地解决了高峰小时超饱和状态下的交通流速度预测问题,为公路网络规划类、经济分析类项目的开展提供了理论基础.
Abstract:
Aiming at the shortcoming in generally used speed-flow relationship model, the theoretical models of speed flow relationship for each highway class are established based upon a large number of collected traffic data. The speed flow relationship model structure under different traffic load conditions is reviewed by analyzing the traffic flow dissipation mechanism under peak hour over saturated traffic condition. A general speed-flow relationship model under any traffic load conditions is established through curve fitting of large number of observed data. The practical model parameters for each highway class under different design speed are also put forward. This model successfully solves the speed-forecasting problem of the traffic flow under peak hour over saturated condition.
