An Optimal Integrated Real-time Disruption Control Model for Rail Transit Systems

摘要: Rail transit systems are subject to frequent minor disruptions caused by random disturbances. Although these usually last no longer than 10-20 minutes, they can degrade the level of service significantly on a short headway service. This paper describes an integrated real-time disruption control model, formulated as mixed integer program, for rail systems, which includes holding, expressing and short-turning strategies. model is capable dealing with multi-branch was applied scenario single line system first step. Two cases 10 20 minute duration tested. The results showed that holding strategies combined reduced mean passenger waiting time 35% in former case 57% latter case, compared not applying any Expressing provided only modest additional benefits. Sensitivity analysis used investigate impact deterministic assumption. solutions were fairly robust, but effectiveness quite sensitive accuracy estimate. In one scenario, increased 14% under estimate 50% less actual duration, result correct Problem instances without be solved 30 seconds computation branch-and-bound algorithm proposed solve this problem.
