Distributed traffic guidance and surveillance system

A traffic guidance system comprising at least one server configured to monitor traffic on a road system in a defined geographical area, wherein the server is configured to receive Global Position System (GPS) data from respective cars together with a unique internet address of respective cars,

• the at least one server is configured to select a set of cars driving in a same direction on a road based on respective GPS positions of the cars, the at least one server initiates a measurement cycle comprising sampling GPS positions from the set of cars with a sampling frequency being a function of an average speed of the cars in the set of cars,
• wherein when a defined number of samples has been acquired a process of investigating a development of distance change between respective cars is performed by the at least one server, identifying if there is a consistent increase or decrease of distance between cars in the defined number of samples,
• if a consistent decrease in distance between cars is detected a probable traffic congestion is upcoming,
• if a consistent increase in distance between cars is detected a traffic congestion is probably dissolving;
• wherein the GPS data together with the unique internet address has the format:
• ‘country-code.city-code.district-code.user-ID.current-GPS’.
