摘　　要：针对道路环形交叉道口不同行车规则对其通行能力的影响进行了研究。首先对四叉口环交禁止换道和允许换道不同的通行规则建立了模型,并研究了不同的车道负载分配情况下的通行能力,推广到多叉口环交,得到n叉口对称环岛通行能力的普适模型,在此基础上提出了环岛行车规则设计建议。To study different impact on roundabout capacity under different traffic rules, we first establishes model on different traffic rules ： lane - changing forbidden and lane - changing allowed of a 4 - lag roundabout. And then disscuss their capacity under different traffic flow allocation among inner lanes and outer lands. We also extent our basic models to multi - lag roundabouts. Finally we get the universal model of n - symmetric roundabout capacity and propose suggestions of traffic rules applied to roundabouts.
