摘要:
常规环形交叉口能够有效避免交通冲突，但随着机动车数量的增加，出现了通行能力不足的问题．提出一种新型立体环形交叉口，通过设置上下两个环圈来解决环形交叉口通行效率较低的问题．利用VISSIM仿真软件，从通行效率和行车安全方面进行模拟，发现相较于常规环形交叉口，新型立体环形交叉口使路网的平均延误降低91.78%，冲突总次数降低73.4%；与简易立交对比发现，新型立体环形交叉口除东西直行方向的通行效率降低外，其余方向均有所提高．进一步分析新型环形交叉口的适应交通量表明，当各入口的交通量小于2 000 pcu/h时，立体环形交叉口能有效提高通行能力，随着右转比例提高，左转比例降低，通行效率的提升更加明显．结合建造成本、占地规模及建造可行性，分析了立体环形交叉口的适用性．在交通量需求较大、相交道路没有主次之分、工程预算不足以修建立体交叉以及可利用土地范围有限等情况下，通过新建或改建成立体环形交叉口可以有效改善路网的运行效率和行车安全．
Abstract:
The conventional roundabouts can effectively avoid traffic conflicts. However, as the number of vehicles increases, insufficient capacity begins to appear. To solve this problem, a new type of roundabout is proposed by setting lane roundabouts on two levels with right-hand turning bypasses. By using VISSIM software, the stereo roundabouts are compared with the actual conventional roundabouts and simple interchanges. The evaluation results show that compared with the conventional roundabouts, the stereo roundabout reduces the average delay of the road network by 91.78%, the total number of conflicts decreases by 73.4%. Compared with the simple interchange, the efficiency of the stereo roundabouts is improved in all directions except the east-west direction. Through further analysis of the traffic volume that stereo roundabouts can adapt to, it shows that the stereo roundabout can effectively improve the traffic capacity when the traffic volume at each entrance is less than 2 000 pcu/h. As the right turn ratio increases and the left turn ratio decreases, the improvement of traffic efficiency is more obvious. Besides, the applicability of stereo roundabout is also analyzed based on the construction cost, floor space and construction feasibility. Under certain circumstances with large traffic demand, no distinction between primary and secondary roads, insufficient project budget for the construction of interchange, and limited land available, the operation efficiency and traffic safety of road network can be effectively improved by building or rebuilding stereo roundabouts.
