| 车行道隔离设施 Roadway Isolation Facilities 1．车行道隔离设施是用来分隔对向或同向行驶的交通流，并有禁止车辆左转进出行驶和行人任意穿越道路的作用，一般设置在道路中心线上或车道分隔线上。车行道隔离设施分为车行道中心隔离设施（分隔对向）和车行道分界隔离设施（分隔同向）。 1. Traffic Lane isolation facilities are used to separate opposite or co-directional traffic, and have the www.hupomoju.cn www.lujianbanmoju.cn www.paomoqiegeji.com.cn www.lianjieqi.org.cn www.baowenganggua.cn www.duihanfalan.com.cnfunction of forbidding vehicles to turn left into or out of the road and pedestrians to cross the road at will. They are generally set on the central line of the road or on the lane separating line. Roadway isolation facilities are divided into central isolation facilities (opposite separation) and boundary isolation facilities (same separation). 2．车行道隔离设施主要采用三种形式：绿化分隔带、隔离护栏、混凝土防撞墙。在市区范围内，优先选取的形式依次为绿化分隔带、隔离护栏；在市郊范围内，优先选取的形式依次为绿化分隔带、混凝土防撞墙、隔离护栏。 2. There are three main types of roadway isolation facilities: green partition belt, isolation fence and concrete anti-collision wall. Within the urban area, the preferred forms are greening partition belt and isolation barrier; in the suburban area, the preferred forms are greening partition belt, concrete anti-collision wall and isolation barrier. 3．同一道路上应设置统一样式的车行道隔离设施。 3. A uniform type of roadway isolation facility should be set up on the same road. 4．符合下列条件之一的新建、改建道路可设置车行道中心隔离设施： 4. New or reconstructed roads that meet one of the following requirements may be equipped with isolation facilities at the center of the roadway: （1）道路中设有高架道路、大型桥梁墩柱的地方又无其它隔离措施的。 (1) Where there are viaducts and large bridge piers in the roads, there are no other isolation measures. （2）桥梁、高架道路、立交、隧道双向交通的出入口与地面道路连接的路段。 (2) The section connecting the entrance and exit of two-way traffic of bridges, viaducts, interchanges and tunnels with the ground road. （3）高等级道路与一般道路双向交通连接的过渡路段。 (3) Transition section of two-way traffic connection between high-grade road and general road. （4）车行道四车道及以上的单幅城市道路。 (4) Single urban road with four lanes or more. |
