摘要
结合厦门市翔安隧道部分路段设置可跨越同向车行道分界线的做法,分析设置可跨越同向车行道分界线前后通行能力和交通事故的变化。针对规范笼统要求隧道设置禁止跨越同向车行道分界线的做法,提出隧道中间段满足一定长度时即可设置跨越同向车行道分界线的条件。
In this paper,the changes of the traffic capacity and accidents are analyzed,based on the setting of the crossable lane line in the same direction in some sections of the Xiang’an Tunnel in Xiamen City.The conditions which crossable lane line is suitable to use when the mid-section reaches a certain length in the tunnel are proposed,other than that is forbidden to do so according to the code.
