Transportation https://doi.org/10.1007/s11116-018-9895-2 A subway planning bi‑objective multi‑period optimization model integrating timetabling and vehicle scheduling: a case study of Tehran 1 1 2 Mitra Heidari · Seyyed‑Mahdi Hosseini‑Motlagh · Nariman Nikoo © Springer Science+Business Media, LLC, part of Springer Nature 2018 Abstract Due to the interaction among different planning levels and various travel demands during a day, the transit network planning is of great importance. In this paper, a bi-objective multi-period planning model is proposed for the synchronization of time- tabling and vehicle scheduling. The main aim of the problem is to minimize the weighted transfer waiting time in the interchange stations along with the operational costs of vehi- cles. In order to demonstrate the effectiveness of the proposed integrated model, a real case study of Tehran subway is considered. The proposed model is solved by the ε-constraint method and some outstanding results are achieved. Keywords Timetabling problems · Vehicle scheduling · Multi-period planning · Subway network Introduction The subway transit network is known as a reliable and energy efficient transit system. To reduce the traffic congestion and the associated environmental pollutions, the subway net - work plays a key role in many large cities over the world (Kang et al. 2015a, b). The transit network incurs crucial drawbacks due
