ABSTRACT
Given demand and coordinated timetables, the next phase is to establish chains of daily trips or vehicle blocs. Each chain or bloc constitutes a vehicle’s schedule for a day. The problem of minimizing the number of chains and, at the same time, fulfilling agency requirements (refuelling, maintenance, etc.) is complex and cumbersome for medium and large-scale transit agencies. This chapter provides an overview of the problem, outlines specific solution procedures and tools, and describes some of the experience with a single transit agency.
