Modified origin-based algorithm for traffic equilibrium assignment problems
Abstract：Key tactics of origin-based user equilibrium (OUE) algorithm was studied,which involved the algorithm procedure and several implementation issues.To speed up the convergence,update policies of flows,costs and bushes were proposed.The methods of step-size searching and bush construction are proved to be practical.The modified OUE algorithm procedure was also optimized to take the advantage of multi-thread process.Convergence performances were compared with those of other algorithms by different sizes of urban transportation networks.The result shows this modified OUE algorithm is more efficient and consumes less time to achieve the reasonable relative gap in practical applications. 作者： Author： ZHANG Tian-ran[1] YANG Chao[2] CHEN Dong-dong[3] 作者单位： Shanghai City Comprehensive Transportation Planning Institute, Shanghai 200040, China;School of Transportation Engineering, Tongji University, Shanghai 201804, ChinaSchool of Transportation Engineering, Tongji University, Shanghai 201804, China;Shanghai Municipal Engineering Design Institute(Group)Co., Ltd., Shanghai 200092, China 期 刊： 中南大学学报（英文版） EISCI Journal： Journal of Central South University of Technology(English Edition) 年，卷(期)： 2011, (5) 分类号： U491 Keywords： traffic assignment origin-based user equilibrium algorithm acyclic network 机标分类号： TU9 TP 机标关键词： problems urban transportation practical implementation methods of algorithms different update time take Key gap 基金项目： Modified origin-based algorithm for traffic equilibrium assignment problems[期刊论文] 中南大学学报（英文版） --2011, (5)Key tactics of origin-based user equilibrium (OUE) algorithm was studied,which involved the algorithm procedure and several implementation issues.To speed up the convergence,update policies of flows,co...【Modified origin-based algorithm for 】相关文章：
