Expressway section and expressway

ZHANG FENG

The invention provides an expressway section and an expressway, and the expressway section is characterized in that the expressway section comprises a starting end which is adjacent to an upstream expressway section; a pavement section which is connected with the starting end along the driving direction; a tail end which is connected with the pavement section along the driving direction and is adjacent to the downstream expressway section, at least two lanes which are arranged on the pavement section, wherein the starting end is provided with at least one entrance ramp, the entrance ramp is communicated with one lane and located on one side of the other lane communicated with the upstream expressway section in the driving direction, and the tail end is provided with at least one exit ramp,the exit ramp is located on the other side of the lane communicated with the downstream expressway section in the driving direction, and the entrance ramp is located on the upstream side of the lanein the driving direction relative to the exit ramp. Through the expressway, the driving efficiency of the lane on the expressway is only limited by the admitting ability of the exit ramp, the controland management of the traffic flow become convenient, and the occurrence rate of traffic accidents is reduced.

本发明提供一种高速路段以及高速公路，其特征在于，高速路段包括：起始端，与上游高速路段相邻接；沿行驶方向与起始端相连接的路面段；沿行驶方向与路面段相连接并且与下游高速路段相邻接的末尾端；以及设置在路面段上的至少两个车道，其中，起始端设有至少一个入口匝道，入口匝道与一个车道相连通并位于与上游高速路段相连通的另一个车道的沿行驶方向的一侧，末尾端设有至少一个出口匝道，出口匝道位于与下游高速路段相连通的车道的沿行驶方向的另一侧，入口匝道相对于出口匝道，位于沿行驶方向的上游侧。通过这样的高速公路，能够使得高速公路上车道的行车效率只受制于出口匝道的接纳能力，车流量的控制及管理变得方便，降低交通事故的发生率。
