高速道路入口匝道通行能力研究

高速道路入口匝道的通行能力主要受３个因素的制约；干道最外侧车道上的车流特性；匝道车辆接受空档的特性；匝道车辆连续跟车行驶特性。因此运用平面优先交叉口通行能力的研究成果，根据高速道路匝道与干道结合部的交通流特性以及我国交通的混合交通流特点，建立了高速道路匝道通行能力模型，并对３个影响因素进行了讨论，最后对数值计算的结果进行了比较和分析。

Research into Freeway On - ramp Capacity

Freeway on - ramp capacity is restricted by three factors: the characteristics of trrffic flow on the outside lane of freeway; the characteristics of gap acceptance by ramp vehicles; the characteristics of continuous car following on a ramp. Borrowed from research achievements in the capacity of priority intersections and based on tLhe characteristics of traffic flow in the area which connects a ramp entrance to the outside lane of freeway and mixed traffic flow in China, the freeway on - ramp capacity model is established and three factors mentioned above is discussed in this paper. Numerical results about three factors are compared and analyzed in this paper.
