| 摘 要： | 对匝道车流与地面车流交织、相位绿灯损失以及邻接路口通行能力不足等问题进行分析;运用时空优化设计方法避免交通流交织与冲突,空间上对交叉口进口车道功能的置换设计,时间上根据车流饱和度均衡原则,提出信号组合相位的设计思想,减少路口有效绿灯时间的损失;最后,通过具体实例对优化设计方法进行验证.结果表明,优化后立交的通行能力提高,车辆的平均延误大大降低,匝道车流与地面车流之间的交织情况基本被消除,改善效益明显. |
| 关 键 词： | 交通设计 匝道 组合相位 交织段 车道功能置换 |

| Abstract: | Problems of vehicle interleaving between a ramp and a ground,the loss of green time,and the shortage of the capacity of adjacent intersections were introduced.Spatial-temporal design methods were applied to avoid interleaving and conflict,a lane functionality replacement was used for the import lanes of intersection in the space,and for the time according to the principle of saturation equilibrium in traffic flow.A design idea about signal combination phase was put forward,which can decrease the loss of eff... |
