采用交通流理论分析旧路中央分隔带开口处车辆行驶特性,并据此计算中分带开口长度;分析中分带开口处车辆受力情况,并评价中分带开口单路拱断面能否满足车辆稳定性要求。
The traffic flow theory was used to analyze the driving characteristics of the vehicle at the opening of the central roadway in the old road, and the opening length of the middle sub-zone was calculated accordingly. By analyzing the vehicle force in the opening of the sub-zone and evaluating whether the single- Vehicle stability requirements.
