Abstract: The existing ad-hoc train operational efforts have mainly emphasized on need-based criteria to serve passenger demand with travel time satisfaction. Although the mass transit system benefits a huge amount of vehicle fuel consumption reduction, the current train operations mostly reveal a lack of environmental consciousness resulting from their skip-stop operational schedules on unserved passengers. This study introduced a new model developed for optimizing and planning train skip-stop operations with its efficiencies in: (1) evaluating the impact of skip-stop operations on passenger travel time; (2) estimating the environmental impacts due to train energy usage and unserved passengers; and (3) optimizing train scheduling decisions to identify competent skip-stop pattern(s) that are simultaneously capable of minimizing total environmental impacts and average passenger travel time. The research methodology started from the data collection on passenger demands and trips to conduct the origin-destination (OD) matrix. Moreover, some other necessary data, such as train operational data and train characteristics, were gathered from the technical reports and past research studies. After that, the passenger travel time estimation and environmental impacts evaluation model were developed in order to estimate the average passenger travel time and CO2 emissions from train operations. Then, the sustainable train stopping pattern optimization model was developed with the aim for planning effective train skip-stop operations. The developed model and analyses were performed on the BTS SkyTrain Silom Line located in Bangkok, Thailand. A wide range of optimal or near-optimal stopping patterns for trains was provided with tradeoffs between the objectives of being environmentally friendly and having an acceptable travel time for passengers. Furthermore, the analysis showed a less significant impact of skip-stop operation for the environmental impacts of train energy usage than the number of unserved passengers. This research study significantly contributes train operation agencies in enhancing their effectiveness due to skip-stop operational schedules. It also benefits the environment toward sustainability in mitigating pollutants as well as the society toward passenger satisfaction and improve quality of service.
