摘　　要：以宏观交通流理论为基础,分析了公交站点位于交叉口进出口不同位置时,交叉口对停靠延误时间的影响,建立了不同情况下公交停靠延误时间模型;分析了速度密度之间的关系,利用Lo-gistic模型对速度密度进行拟合,计算出了路段平均速度.实例验证表明基于宏观交通流理论的行程时间估计方法具有较高的精度,可以满足站点间行程时间预报要求.Bus operation process is analyzed between bus stops, and the estimated travel time is divided into two parts, stopping delay time and link travel time. The impact of intersection on stopping delay is analyzed and the stopping delay models are established with macroscopic traffic flow respectively when bus stops are located in entrance and exit of intersection. The relationship between the speed and density is analyzed and the logistic model is used to fit it to calculate the average speed. The ex- perimental data show that the estimation method based on macro traffic flow has high precision to meet the forecasting requirement for travel time between bus stops.
