Abstract

Fundamental changes in urban mobility patterns have led to an unpredictable and non-stationary surge in vehicle volume, driven by Work From Anywhere policies and a significant increase in private vehicle usage and ride-hailing services. Consequently, a new paradigm integrating artificial intelligence with advanced computing infrastructure is required. This study constitutes a literature review aimed at providing a comprehensive critical analysis of Deep Reinforcement Learning models and Edge Computing schemes within the context of Adaptive Traffic Signal Control, with particular focus on implementation challenges in the new normal mobility era. The findings reveal four primary insights. First, Multi-Agent Deep Reinforcement Learning architectures incorporating communication mechanisms based on Graph Neural Networks demonstrate superior performance in multi-intersection scenarios, yet remain vulnerable to distributional shift phenomena caused by non-stationary travel pattern changes. Second, Edge Computing theoretically reduces latency and enhances system resilience to network failures, although its deployment is constrained by computational resource limitations and energy consumption issues on edge devices operating in extreme intersection environments. Third, an overreliance on simulation data from SUMO or VISSIM introduces significant validity gaps when models are applied to real-world mobility dynamics influenced by heterogeneous data sources such as probe vehicles and loop detector sensors. Fourth, implementation barriers are multidimensional, encompassing computational complexity, susceptibility to adversarial attacks on DRL policies, and regulatory and interoperability gaps with legacy infrastructure. The practical implications of this research emphasize the development of compact DRL models leveraging knowledge distillation for low-power edge devices, alongside technical interoperability guidelines to facilitate gradual transition from conventional systems.

Abstract

This study addresses the critical issue of escalating traffic accident rates in Indonesian urban areas, which recorded 101,904 cases as of September 2024. Current conventional methods for identifying accident-prone areas (blackspots) remain primarily reactive and lack the capability for early risk prediction. Conversely, while Digital Twin and Big Data Analytics technologies offer transformative potential for real-time road modeling, their integration into road engineering for the proactive prediction of accident blackspots in Indonesian urban contexts has not been systematically elaborated. This research employs a qualitative-descriptive library research approach, utilizing data sources that include academic books, scientific journal articles, and research reports. The collected data were analyzed using thematic content analysis techniques. The findings of this study reveal four primary conclusions. First, Digital Twin technology enables a virtual representation of road networks integrated with real-time sensor data, thereby creating a cyber-physical system capable of simulating diverse traffic scenarios. Second, Big Data Analytics possesses the capacity to process vast volumes of heterogeneous data including GPS, telematics, CCTV footage, and social media inputs to identify accident risk patterns that typically elude conventional statistical methods. Third, the integration of Digital Twin and Big Data Analytics facilitates the development of a risk prediction platform capable of proactively identifying accident blackspots with significantly higher accuracy than traditional approaches. Fourth, the implementation of these technologies in Indonesian urban areas encounters substantial challenges, notably limited data infrastructure, insufficient human resource capacity, and inadequate regulatory frameworks. This study concludes that the utilization of Digital Twin and Big Data Analytics in road engineering constitutes a highly promising strategy for the early prediction of urban accident blackspots. The implications of these findings underscore the necessity for targeted investments in data infrastructure, human capital development, and the formulation of regulatory frameworks that support the gradual and context-specific adoption of these technologies.
