数字化城市过江通道选线研究及重要节点分析

Study on Route Selection and Analysis on Important Nodes of Digital Urban River Crossing

基于规划开发及设施供给上位规划,从省域、同城化、市域三个层面对过江通道的交通流量进行预测,城际间跨江通道的建设代价较大,首先需要考虑交通功能。过江通道一般位于城市区域,建筑密度大,利用BIM和无人机倾斜摄影技术进行现状分析可以为选线提供更为直观的数据分析,从而为线位的选择提供数据支撑。对于多岔路交叉的重要节点,应简化立交形式,着重便利主流交通,通过多个节点互补的形式解决交通问题,尽量不要集中一点解决,避免形成交通拥堵黑点。

Based on the planning and development,and the facility supply upward planning,the traffic flow of the river crossing is predicted at three levels of province,urban integration and municipal area.The construction of intercity river crossings is costly.Firstly,it is necessary to consider the transportation function.The river crossing is generally located in urban areas with high building density.The status quo analysis using BIM and drone tilt photography technology can provide more intuitive data analysis for the selection of alignment so as to provide the data support for the selection of alignment.For the important nodes crossed by multiple forks,the form of interchanges should be simplified.The mainstream traffic is specially solved.The traffic problems are solved through the form of multiple nodes complementing each other,which try not to focus on one point to solve the problem,and avoid the formation of traffic congestion black spots.
