A method to calculate the benefits of urban traffic management system implementation

Urban traffic congestion is a problem in almost all big cities around the world. Traffic management systems have been implemented in various forms, based on different algorithms, each one trying to achieve better performances than the others having the goal to improve as much as possible urban road traffic. In most cities new modules are added on top of the existing ones, trying to improve their performances. Bucharest is a special case, due to the fact that a modern traffic management system was put in place from zero, thus creating a very good opportunity to calculate the benefits such a system can obtain in comparison with the previous situation, where no centralized traffic management system existed.
