From the introduction: "In planning our lectures for this seminar, my colleagues and I have decided that we present here an overview of the problems of cities today, of the role of public transportation, and especially high-performance public transportation, as well as some details of planning, and characteristics of modes, their design and operations. We will thus try to combine, as much as the time allows, a general overview with technical details which many of you will be facing when you will be planning and implementing your rapid transit project in the years to come."
