Multi-Objective Optimization of Train Timetable with Consideration of Customer Satisfaction

This paper presents a multi-objective optimization framework for mainline train timetabling with consideration of customer satisfaction. The customers’ perspectives considered include their perceptions of service punctuality, waiting times, and comfort of journeys. The optimization formulation is subject to constraints representing operational requirements and signaling systems. The optimization model is applied to the Brighton main line network in south-east England as a case study, and the results demonstrate how the proposed optimization framework can help government and train operators to derive more effective and equitable timetables with consideration of customer satisfaction.
