Methodological Framework for Sustainable Transport Corridor Modeling Using Petri Nets

Current models for evaluating sustainable transport corridors often lack a comprehensive framework capturing the multifaceted performance measures vital for holistic assessment especially at the early stages of operation, when detailed information on the performance indicators of these transport corridors is not available. This gap motivates a Petri net-based modeling approach that integrates key sustainability indicators into a flexible simulation tool. This paper details a versatile methodology harnessing Petri nets, specifically Evaluation Petri nets (E-Nets), to assess corridor sustainability across environmental, social, and economic dimensions. The proposed framework equips planners and policymakers to explore diverse green corridor configurations under varying conditions. Case studies showcase the model's capabilities in analyzing real-world corridors, identifying performance bottlenecks, and comparing alternative solutions. The model provides a practical decision-support tool to strengthen strategies for efficient, socially responsible, and environmentally sound transport infrastructure. This research advances the theoretical foundations and demonstrates the practical value of Petri nets as an enabling methodology for modeling the intricate dynamics of sustainable transport corridors. This paper demonstrates how E-Nets provide a visual and quantitative representation of transport operations, enabling stakeholders to identify inefficiencies and potential improvements. This paper discusses the theoretical underpinnings of the E-Net modeling of transport corridors, the advantages and limitations of its application, and suggests avenues for future research to enhance the model's predictive power and real-world application. The paper concludes that the E-Net approach is a scalable, adaptable tool that can significantly con-tribute to the sustainable development of international transport corridors, providing a framework for continuous improvement in alignment with global sustainability objectives.
