Improvements of Dr.METRO and its Applications to Urban Railway Scheduling

초록

This paper addresses improvements of Dr.METRO and its application to examine a SKIP-STOP scheduling for a Seoul urban railway. It has already been introduced in two international conferences such as ‘COMPRAIL 2014’ in Rome and ‘UITP Asia-Pacific Assembly’ in Tokyo 2014. This paper presents four major improvements on the software program after the conferences. First improvement is upgrades in MIP model on infeasibility management and reducing variables. Second one is a heuristic train scheduling algorithm newly developed. Third is a re-optimization function to have users more satisfied to an outcome of train schedule. Last one is improvement in computation time and correctness of estimation of a schedule based transit assignment algorithm. In addition, this paper introduces an experience of examination on SKIP-STOP scheduling to operate express trains together with normal trains in Seoul urban railway Line #7.
