With daily commercial and social activity in cities, regulation of train service in massudrapid transit railways is necessary to maintain service and passenger flow. Dwell-time adjustment atudstations is one commonly used approach to regulation of train service, but its control space is veryudlimited. Coasting control is a viable means of meeting the specific run-time in an inter-station run.udThe current practice is to start coasting at a fixed distance from the departed station. Hence, it isudonly optimal with respect to a nominal operational condition of the train schedule, but not theudcurrent service demand. The advantage of coasting can only be fully secured when coasting pointsudare determined in real-time. However, identifying the necessary starting point(s) for coasting underudthe constraints of current service conditions is no simple task as train movement is governed by audlarge number of factors. The feasibility and performance of classical and heuristic searchingudmeasures in locating coasting point(s) is studied with the aid of a single train simulator, accordingudto specified inter-station run times.
