Analysis, Modeling and Simulation of Traffic Flows in Petrosani City in Regard to Optimizing Urban Mobility and Ensuring Road Safety

The paper examines the general characteristics of the analyzed area, data collection, transport model, structure, dynamics and current problems of urban mobility in Petrosani city, with a focus on identifying efficient solutions to reduce congestion and improve accessibility. The study is based on an integrated approach, combining traffic data analysis with modern modeling and simulation techniques, using dedicated software tools to replicate the real behavior of road flows. The diagnostic analysis highlights the critical points of the transport network, the causes of traffic jams, the temporal distribution of traffic and the interaction between mobility modes. By building a model calibrated on real data, the research tests different intervention scenarios – optimizing traffic lights, reorganizing traffic, expanding infrastructure, introducing dedicated public transport lanes and promoting alternative mobility. The simulation results show the significant potential of the proposed interventions to reduce travel times, fuel consumption and pollution levels, contributing to increasing the quality of urban life. The paper provides a coherent set of strategic recommendations that can support the local administration in planning the sustainable urban mobility in Petrosani city, aligned with European standards and policies regarding sustainable transport.
