Countries all over the world especially most capital cities in particular, have been trying to overcome traffic problems for years. This is due to rapid economic and social growth. As the rapid growth in the number of cities increases so does the number of private vehicles, leading to traffic congestion, negative environmental problems like noise and air pollution and not to mention, the increase in the number of accidents. Traffic congestion is getting worse everywhere and sadly this does not just apply to the capital cities at rush hour. This book has been aimed at getting familiar with the concept of public transport systems and reviewing the application domain of the systems developed for traffic management, and advanced transportation information systems and also the advanced systems to control vehicle and safety; with a discussion of the importance of each and its relevance to the reality.
