【摘要】 对于多因素问题的实验分析,正交试验设计(OED)是一种高效率的方法。本文提出了将正交试验设计方法应用于阻塞影响因素显著性分析,并归纳了城市道路信号控制交叉口群交通阻塞的影响因素。最后,以张家港市长安路交叉口群为实际分析案例,运用OED方法进行了该交叉口群阻塞影响因素的显著性分析,得到了流量与相序两个因素显著性最强的结论,并提出了针对性的交通改善建议。更多还原

【Abstract】 Orthogonal Experimental Design(OED) is an efficient method to the analysis of multi-factor problems.This paper applies OED method to the analysis of factors causing congestion.Then,the factors on urban signalized intersections are sorted into three categories.Based on traffic simulation software,the OED method is found feasible through a real sample of the city of Zhangjiagang.Also,it concludes that flow volume and phase plan are the most significant factors affecting urban congestions in the city of Zhangjiagang and,therefore,they should be taken into great consideration to relieve congestions.更多还原
