Graph-Theoretic Optimization of Transportation–Communication Networks: A Mathematical and AI-Enabled Framework for Adaptive Intelligent Transportation Systems
Subject area: Science,Engineering and Technology · Area of research: Mathematics
Abstract
The rapid development of urbanization, smart cities, autonomous transportation, and connected vehicle technologies has transformed traditional transportation systems into highly complex cyber-physical networks. These networks integrate physical transportation infrastructures such as roads, railways, and intersections with communication infrastructures including wireless sensor networks, vehicular ad hoc networks, and cloud-based traffic management platforms. Efficient optimization of such interconnected systems requires advanced mathematical models capable of representing dynamic relationships, identifying optimal pathways, and improving network reliability. Graph theory provides a fundamental mathematical framework for analysing transportation communication networks by representing network components as vertices and connections as edges. This research proposes an advanced graph-based optimization framework that combines weighted graph modelling, shortest path algorithms, network flow optimization, spectral graph theory, and artificial intelligence-based graph learning methods. The proposed model considers multiple optimization parameters including travel distance, congestion level, communication latency, energy consumption, and network reliability. A dynamic weighted graph model is developed: where time-dependent edge weights enable real-time adaptation according to changing transportation conditions. The research formulates a multi-objective optimization function to minimize total transportation cost while maximizing communication efficiency and network resilience. Furthermore, Graph Neural Network (GNN) integration is investigated for predictive traffic modelling and adaptive decision-making. The proposed framework provides a mathematical foundation for intelligent transportation systems by enabling optimal routing, congestion reduction, efficient resource allocation, and improved communication performance. The study demonstrates that graph theory combined with artificial intelligence can support next-generation transportation infrastructures including smart cities, autonomous vehicle networks, and intelligent mobility platforms. Recent studies confirm that graph-based models and GNN approaches are becoming increasingly important in intelligent transportation systems because they can represent complex spatial and temporal relationships in traffic networks.
