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.
This paper proposes a comprehensive framework integrating AI, IoT, and autonomous vehicles to optimize urban logistics in smart cities. The framework includes intelligent traffic signal control systems, real-time traffic monitoring, adaptive traffic management strategies, and big data analytics for traffic prediction and optimization.

Barcelona, Spain
Barcelona has implemented smart parking solutions using IoT and AI to manage parking spaces and reduce traffic congestion. AI algorithms analyze real-time data from parking sensors to guide drivers to available parking spots, reducing search time and traffic. Increased parking efficiency, reduced vehicle emissions, and improved urban mobility for both residents and visitors.
The high-tech advancements throughout Barcelona provide a compelling model for other cities aiming to enhance their technological infrastructure. Barcelona has introduced a sensor system to help drivers locate open parking spots. These sensors, embedded under the asphalt, detect available spaces and notify drivers, reducing emissions and congestion by directing them to vacant spots. Within the first year of implementation, the city issued 4,000 parking permits daily. Additionally, there is an online payment option for parking fees [13].
The Transports Metropolitan de Barcelona (TMB), the city's transport system, has implemented a new orthogonal bus network consisting of diagonal, vertical, and horizontal lines. This network is designed to be more frequent, user-friendly, and faster. The goal is for travelers to make only one transfer between any two points in the city for 95 percent of their journeys. The bus transit system also promotes urban sustainable mobility by reducing emissions through the use of hybrid buses. Furthermore, it features smart bus shelters equipped with solar panels and screens that display waiting times [13].

Copenhagen, Denmark
Copenhagen utilizes AI-powered bike-sharing systems integrated with IoT to promote sustainable transportation options. IoT sensors track bike availability and user data, while AI algorithms optimize bike distribution and maintenance schedules. Enhanced bike-sharing program usability, increased ridership, and reduced reliance on traditional vehicular transportation in urban areas [14].
Copenhagen's commitment to sustainable commuting is exemplified by its diverse transportation options. With over 49% of residents preferring bicycles as their main mode of transportation, the city's public transport system complements this biking culture seamlessly.
Copenhagen's public transport system, which includes buses, regional and local trains, and the metro, forms a well-integrated network operated by entities such as DSB, Movia, and Copenhagen Metro. This interconnected system reduces the need for private vehicles, making sustainable commuting choices more accessible. The Copenhagen Fingerplan, developed in 1947, is a significant urban development initiative that advocates for a decentralized city structure. It introduces "fingers" of green spaces extending from the city center, such as parks and forests, strategically designed to guide the city's growth while preserving its natural surroundings. This plan aligns perfectly with Copenhagen's strong biking culture [14].
The efficiency and reliability of Copenhagen's public transport system are crucial in encouraging residents to choose greener alternatives. Regular schedules, punctual services, and well-connected routes make public transport a compelling choice for daily commuting. For example, Implement Consulting Group has noted how a reliable bike solution has helped their employees increase productivity and reduce time spent in transit.
