AI-Driven Optimization of Urban Logistics in Smart Cities: Integrating Autonomous Vehicles and IoT for Efficient Delivery Systems

1. Introduction

Urban logistics, which involves the transportation and delivery of goods within city environments, is a crucial aspect of contemporary urban planning and management. Effective logistics largely contributes to the success of business through quick deliveries in minimum time and cost [1]. As urban populations increase, the demand for efficient logistics rises, leading to challenges such as traffic congestion, pollution, and inefficient resource utilization. Smart cities aim to address these challenges by leveraging advanced technologies to create more efficient and sustainable urban environments. In this context, integrating artificial intelligence (AI), autonomous vehicles, and Internet of Things (IoT) technologies offers a promising solution to optimize urban logistics.

The rapid advancement of AI has enabled significant improvements in data analysis, decision-making, and automation. Mohsen [2] reported that AI can be used to optimize logistics, such as transport routes, and scheduling of production and delivery, reducing costs and improving efficiency. AI algorithms can process vast amounts of data in real-time, providing insights and predictions that enhance the efficiency of urban logistics operations. For example, AI-driven traffic signal control systems can dynamically adjust signal timings based on real-time traffic conditions, reducing congestion and improving the flow of delivery vehicles [3]. Similarly, AI-based adaptive traffic management strategies can respond to changing traffic patterns and delivery demands, optimizing the routing of delivery vehicles [4].

IoT technology complements AI by providing the necessary data inputs. IoT sensors deployed throughout urban infrastructure collect data on traffic conditions, vehicle locations, and environmental factors. This real-time data is crucial for AI algorithms to make informed decisions. The development of IoT technology paves the way for the more thorough fusion of digital and physical systems. Over time, data intelligence and pattern analysis allow for exact forecasts and action in the case of incorrect operations [5]. For instance, IoT-enabled smart transportation infrastructure can monitor and manage traffic flows, enabling more efficient and timely deliveries [6]. Furthermore, integrating autonomous and connected vehicles into the urban logistics network can significantly enhance delivery efficiency and reduce human error [7].

The use of Big Data in supply chain activities significantly enhances efficiency, particularly in logistics [8]. Big data analytics, a crucial element of smart urban logistics, utilizes machine learning techniques to examine extensive datasets and generate actionable insights. By analyzing traffic data, delivery patterns, and consumer behavior, big data analytics can optimize delivery routes, shorten travel time, and decrease fuel consumption [9]. Additionally, AI-powered smart parking solutions can manage parking spaces for delivery vehicles, ensuring quick access and reducing idle times [10].

Sustainable transportation policies are integral to developing smart cities. AI-driven approaches can promote eco-friendly logistics practices, such as using electric vehicles and optimized delivery schedules, to reduce the carbon footprint of urban logistics [11]. These practices align with the broader objectives of smart city initiatives, which aim to create more liveable, efficient, and sustainable urban environments.
