| 摘 要： | 城市高架快速路是改善城市交通环境的重要手段之一。在城市建成区内,高架快速路匝道建设受到现状路网制约较多,匝道布置从区域路网交通分析来看,满足交通功能的前提下,可供选择建设地点一般建设条件有限,一般匝道落地点距离地面平交口较近。该文分析交织段的交通行为,辅以工程实例,探讨快速路匝道与地面平交口之间的配合问题,提出从改善交织区的交通通行能力方面进行工程及控制措施,提高快速路与地面平交口的匹配能力。

| Abstract: | The urban elevated express road is one of the important means to improve the urban traffic environment.The construction of elevated road ramp is more restricted by the present road network.By analyzing the traffic of the areal road network and under the premise of satisfying the traffic functions,the general construction conditions of the position able to be selected for the ramp layout is limited.The ramp landing point is generally closer to the ground intersection at grade.The article analyzes the traffic... |
