时空重塑与科技赋能下的交叉口拥堵治理策略

Management Strategies for Intersection Congestion under Spatiotemporal Reshaping and Technological Empowerment: A Case Study of Chuangxin Avenue - Yunfei Road Intersection in Hefei

摘要:

城市道路交叉口作为交通流转换的关键节点，其运行效率与安全性直接影响城市交通系统的整体性能。以合肥市创新大道与云飞路交叉口为研究对象，针对其在慢行路权、空间尺度、交通组织、信号控制等方面存在的典型问题，提出“时空重塑+科技赋能”的系统性治理思路，综合运用交叉口压缩、慢行路权明确、右转半径优化、交通渠化调整、自适应信号控制等手段，显著提升路口通行效率与安全性。研究结果表明，“时空重塑+科技赋能”的治理策略可有效破解城市复杂交叉口拥堵难题，可为同类型交叉口精细化治理提供可复制的实践经验。

Abstract:

As key nodes for traffic flow conversion, the operational efficiency and safety of the urban road intersections directly affect the overall performance of the urban traffic system. Taking the intersection of Chuangxin Avenue and Yunfei Road in Hefei as a research object, aiming at the typical challenges in slow-traffic rights, spatial scale, traffic organization, and signal control, a systematic management idea centered on "spatiotemporal reshaping and technological empowerment" is proposed. By comprehensively applying measures such as intersection compression, clarification of slow traffic rights, optimization of right-turn radius, adjustment of traffic channelization, and control of adaptive signal, the traffic efficiency and safety at intersections are significantly enhanced. The research result indicates that the governance strategy of "spatialtemporal reshaping and technological empowerment" can effectively resolve the congestion at the complex urban intersections, providing the replicable practical experience for the refined governance of similar intersections.
