机非混行交叉口右转机动车通行能力研究

针对机非混行交叉口，为了定量计算不受信号控制的右转机动车道的通行能力，以右转机动车和直行自行车的冲突机理为基础，应用间隙理论，分别建立两相位和四相位信号控制交叉口右转机动车道通行能力计算模型，并应用石家庄市两相位信号控制交叉口的实际调查数据，对模型进行验证，结果表明，误差在可接受范围内，该模型可靠。本文结论为通行能力计算提供新的思路和方法。

Research on the Capacity of Right - turn Vehicle at Vehicle - bicycle Mixed Intersection

In order to compute the capacity of right - turn vehicle without signal control quantitatively at vehicle -bicycle mixed intersection, the conflict mechanism between right - turn vehicle and straight bicycle is researched as basis. The computer model for capacity of right - turn vehicle is established at signal control intersection with two -phase and four - phase respectively using gap theory. The model is validated by practice survey data of two - phase signal control intersection for Shijiazhuang. The result showed that the error is acceptability and the model is credibility. The conclusion provides the new idea and approach.
