Urban Transport Strategy. Management in Developing Countries John A Cracknell, страница 3

The question was posed to the Review as to "what measures work best" in developing cities.  A response in the form of general guideline is not possible.  Traffic management measures:

♦       are highly city-specific, depending on city size, level of development, level of traffic congestion, traffic characteristics, ability to enforce etc and measures which are successful in one city may not be appropriate or successful in another;

It is fundamental to the development and implementation of a successful traffic management program that there exists, or is created:
