短连线交叉口群通行能力计算方法研究

针对短连线交叉口群的通行能力计算提出了相应的理论和方法。文章首先从不同角度对短连线交叉口群进行了界定，然后利用波动理论和车流运行的时空图，建立了短连线通行能力和损失的通行能力计算模型，并采用数学方法建立了通行能力及其损失量随着各个影响因素变化的图表。从中得出了一些重要的结论，且在信号协调控制方面提出了一些建议。

Methods to Calculate the Capacity of Short-link Grouped Intersections

A relevant theory and method of model to calculate the capacity of short-linked grouped intersections is proposed in this paper. At first, the paper gives the definition of short- linked grouped intersections from multiple aspects. Then, a model to calculate the short link capacity and the lost capacity is built by using wave theory and time-spaced diagram. A series of diagrams are acquired in the approach of numerical experiment, showing that the short-link capacity and the loss capacity vary according to the respective variable group. In the end, the authors make some useful conclusions and give some suggestions in coordinated signal control.
