This is the only current and in print book covering the full field of transit systems and technology. Beginning with a history of transit and its role in urban development, the book proceeds to define relevant terms and concepts, and then present detailed coverage of all urban transit modes and the most efficient system designs for each. Including coverage of such integral subjects as travel time, vehicle propulsion, system integration, fully supported with equations and analytical methods, this book is the primary resource for students of transit as well as those professionals who design and operate these key pieces of urban infrastructure.in Figure 3.10, remain the same regardless of whether rheostatic or chopper controls are used. Compared to rheostatic DC motor control, SCREC choppers, now succeeded by GTO and IGBT electronic inverter controls of AC ... Generally, the reduction in energy consumption achieved by regeneration can be as high as 20% to 30% on urban lines with ... Lower maintenance costs of chopper and inverter controls result from the use of solid-state components instead of numerous movinganbsp;...
