Ozturker M. Methods for Urban Assessment of City Arterial Network’s Capacity (on the example of city Lutsk)

The object of study is city transport-planning system. The aim of the research is to develop a method of urban assessment of city arterial network's capacity using the methods and models of classical gas dynamics. Methods are based on: - analysis, synthesis, comparison, classification when processing the theoretical and practical background in urban planning, transport planning, organization and traffic management, mathematical theories of traffic flow and hydro/gas dynamics; - system-structural analysis of transport-planning system; - mathematical traffic modeling (graph theory, gas-dynamic analogy), equations of state, continuity, motion, Kirchhoff's laws, classical gas dynamics models. The most promising way to manage transport-planning system is the introduction of Intelligent Transportation Systems (ITS), the efficiency of which depends on the adequacy of the traffic flow model. The possibility and correctness of application of gas-dynamic analogy for assessing the capacity of arterial road network has been proven. The method of urban assessment of city arterial network's capacity has been developed on the basis of coordination method of gas distribution networks considering functioning specifics of transport-planning systems. The method gives the possibility to assess the current state of the system and the effect from the measures applied, is not dependent on the city size and takes into account city influence area.
