Parking Guidance as ITS Support for Sustainable Traffic in the City of Zagreb

Road traffic, as one of the basic preconditions for the development of any city – metropolis, is entering ever deeper into a phase of failing to be sustainable. Thus, in the City of Zagreb as well, the number of vehicles in the recent ten years has doubled and is approaching the half-million figure, and the capacities defined by the urban space have remained the same. How to harmonize the supply and the demand in the field of traffic – this is the basic issue of the city development sustainability. The work presents the implementation of advanced telematic technologies (Intelligent Transport Systems - ITS) in the function of guiding vehicles to free parking spaces in the public garages (PG). The paper provides a proposal for the basic guidelines of functional specification with special development of the algorithm with real-time presentation of free spaces.
