Bus rapid transit (BRT) systems are found in cities throughout the world. Their operating flexibility and their ability to be built quickly, incrementally, and economically underlie their growing popularity. The systems vary in design, operations, usage, and effectiveness. Collectively, the case studies on BRT provided on the CD-ROM accompanying this volume give a wealth of information on BRT and how it should be planned and implemented. This report draws on the experiences of 26 urban areas in North America, Australia, Europe, and South America. Most of the BRT systems reviewed are in revenue services, and a few are under construction or development. Information was assembled for each case study on institutional arrangements, system design, operating practices, usage, costs, and benefits.
