In Mihajlo Pupin Institute the research in the area of traffic control and management has been carried out for more than 30 years. The conducted research can be divided into two main streams:

• Urban traffic control and management, and

• Motorway and highway traffic control and paytoll systems

The research concerned with urban traffic control deals with isolated intersection control, arterial control and area traffic control. Various methods of system analysis and optimization algorithms have been applied, resulting in original traffic control methods and computer programs. Mihajlo Pupin Institute, for example, was one of the first world companies having computerized traffic contol system applications.

In the area of motorway and highway control systems the research has been directed toward application of changeable traffic signs and paytoll systems. As for paytoll systems, IMP was one of the first companies in the world that designed, developed and implemented a paytoll system based on PC technology. From this system, the system for fare collection in garages and parking lots emerged. Since the first paytoll system, three generations of paytoll systems have been developed, so that nowadays IMP presents a distinguishable and competitive producer in this area in the world.

The latest research activities include the application of GPS technology for vehicle location services. Various systems have been designed, developed and implemented, for different investors, including open pit mines, public transport, communal organizations, military applications, etc.
