摘　　要：本文以东钱湖大道—锁岚路交叉口为例进行研究,提出“隔离绕行+信号控制”的交通组织优化策略,并对比评估该交叉口改造前后事故率、平均延误等关键参数的变化。结果显示:该交叉口事故率下降85.3%、整体延误下降90.4%,平均延误时间下降至2.3 s。本研究对规范环形交叉口的交通秩序、改善其交通安全、提高其通行效率具有一定的参考意义。This paper takes Dongqianhu Avenue-Laolan Road intersection as an example,proposes the traffic organization optimization strategy of“isolation bypass+signal control”,and compares and evaluates the changes of key parameters such as accident rate and average delay before and after the intersection reconstruction.The results show that the accident rate of this intersection decreases by 85.3%,the overall delay decreases by 90.4%,and the average delay time decreases to 2.3 s.The research in this paper has certain reference significance to regulate the traffic order of roundabouts,improve its traffic safety and enhance its traffic efficiency.
