This discussion of the contribution to be expected from a comprehensive application of modern automation and computer technology in the solution of serious urban traffic problems, pays special attention to the new possibilities provided by recently developed LSI (large scale integrated) electronic systems for control, computation and communications, especially by so-called mini-computers and and microprocessors. It is shown that computerized urban traffic control systems play an important role in the improvement of existing transportation systems, especially of urban railway systems and freeway and street transportation systems. Demonstration projects in different countries indicate that automation and computer control may provide the possibility of fundamental changes in existing in existing urban transportation systems during the next ten years. However, problems and conflicting opinions exist regarding the safety and reliability of totally automated systems, cost benefit analysis, risk evaluation, public acceptance, and the prediction of the effects of introducing new modes of transportation on the quality of urban living and city development. At present there is no certainity that automated transportation modes now being developed will bring the needed breakthrough to better urban transportation. However, there is a strong motivation to to proceed in the development of new demand-responsive urban transportation systems. Concepts for the reduction of urban traffic problems are discussed and include control of demand and supply. Freeway and road traffic control, traffic control in urban street networks, and integrated urban automobile traffic control systems are discussed, urban railway systems control and new modes of urban transportation are considered.
