Abstract
Keywords: urban trafic, optimization, mathematical model, procedure system identification
The utlization of some algorithms for street traffic optimization constitutes the first and the most important step in realization of efficient management circulation systems.
The processes which take place in this domain are complex, relying on the aleatory element, the mathematical models can be elaborated basing on data and information taking only. The procedures used with this purpose can be allocated to the procedures known as system identification. In concordance to this type of procedures relying on data analysing and processing one can obtain theoretical statements which constitute the mathematical models searched for.
The autors have been concerned with street traffic optimization on local, but also regional areas, realizing researches, carrying out studies and buiding appropriate mathematical models.
For a component of the central street network of Craiova town, with the input parameters signal periods, fazes, crossing time periods, intersection’s configuration, data about the traffic volumes, one can realize original mathematical models which allow the algorithmic approach of programming sequences in order to ensure maximun fluency and minimum pollution.
For models validation one resorted to the values of multiple correlation coefficient from the perspective of determinist connections.
