摘要
针对中新天津生态城彩虹桥路网,存在的交通拥堵问题,设计了一种中新天津生态城彩虹桥并线设计方案.首先,分析彩虹桥周边路网情况,确定彩虹桥路网拥堵存在的问题:信号灯控制方案和彩虹桥道路并行设计.然后,分析彩虹桥路网存在的问题.并根据中新天津生态城彩虹桥并线设计原则,实现彩虹桥并线方案设计.最后,利用实验验证本文方法的交通拥堵解决效果.通过对比本文方法与传统方法在不同时间段通过彩虹桥的车辆数量,得出本文方法能通过更多的车辆.实验结果表明本文设计的彩虹桥并线方案,能改善中新天津生态城彩虹桥路网状况,具有较好的应用意义.
Aimingat solving the traffic congestion problem in the existing Rainbow Bridge Road Network in Sino Singapore Tianjin Eco-city,this paper proposes a design scheme of Rainbow Bridge Parallel Line in Sino-Singapore Tianjin Eco-city.First,the road network around the Rainbow Bridge is analyzed,and two aspects of the congestion problem of the rainbow bridge road network are identified:the signal control scheme and the parallel design of rainbow bridge road.Then,the existing problems of the rainbow bridge road network are analyzed.According to the design principle of rainbow bridge in Sino Singapore Tianjin Eco-city,the scheme design of rainbow bridge is realized.Finally,an experiment is conducted to verify the effectiveness of the proposed method.By comparing the number of vehicles passing through the Rainbow Bridge in different time periods between this method and the traditional method,it is concluded that this method can pass more vehicles.The experimental results show that the rainbow bridge parallel scheme proposed has good application significance,and can effectively improve the situation of the Rainbow Bridge Road Network in the Sino-Singapore Tianjin Eco-city.
