中文摘要：

以便与分支道路的合理利用减少城市的动脉的道路的交通压力，没有划分小巷的分支道路上的车辆会议行为被描述，并且细胞的自动化( CA )模型被介绍会议行为反映在安全会议速度和道路宽度之间的关系提出。数字模拟结果描绘在道路节能力，在交通流动的不同方向性的分布下面的速度和道路宽度，以及在主要、次要的方向浸透流动，速度和道路宽度之间的弯曲之间的几关系弯曲。这些关系特征显示除了仍然保持未改变的单程的道路节能力和速度，在不同方向性的分布下面的另外的道路节能力和速度随道路宽度的增加增加。在狭窄的道路上，双向交通能力和速度是单程的交通的不到那些；在宽道路上，双向交通能力加倍单程的交通的，但是他们的速度是几乎一样。作为到 50/50 的平分布的方向性的分发行动，主要方向浸透象次要的方向速度一样流动并且加速趋于死亡，当次要的方向浸透流动趋于增加时。

英文摘要：

In order to reduce the traffic pressure of urban arterial road with the rational utilization of the branch road, the vehicle meeting behavior on the branch road without divided lane was described, and the cellular automation （CA） model was put forward by introducing meeting behavior to reflect the relation between safe meeting speed and road width. The numerical simulation results depict several relation curves between road section capacity, speed and road width under different directional distributions of traffic flow, as well as the curves between the major and minor direction saturation flow, speed and road width. These relation characteristics indicate that except the one-way road section capacity and speed remaining unchanged, other road section capacities and speeds under different directional distributions increase with the increase of road width. On narrow road, the two-way traffic capacity and speed are less than those of one-way traffic; on wide road, the two-way traffic capacity doubles that of one-way traffic, but their speeds are almost the same. As the directional distribution moves to an even distribution of 50/50, the major direction saturation flows and speeds as well as the minor direction speeds tend to decease, while the minor direction saturation flow tends to increase.
