Abstract
This study, from the operator's viewpoint, combines the advantages of the headway adjustment models in both Middle and Heavy Rapid Transit systems in Taipei to develop a hat-curve straightening model to deal with the headway recovery problems when train delays occur. In the first step, a dynamic objective schedule is generated automatically for all service trains to catch up with. The model then updates the objective schedule step-by-step in order to gradually make the system recover from the delay situation.
