Selected modern traffic management centers (TMCs) illustrate how large cities and their regional surroundings manage the increased vehicle volume and complex traffic structures safely and efficiently, while providing comprehensive and reliable traffic information to road users. The two editors, both recognized traffic experts, have succeeded in compiling a comparative overview of the different approaches to information management, equipment, and strategies for metropolises such as Frankfurt, Stuttgart, and Berlin. In addition to the various organizational and operational forms, the traffic engineering system components and the necessary management processes are particularly highlighted. The authors, all senior staff members in the traffic centers and leading service providers, present situations from their practical experience.
