Sustainable urban logistics encompasses a rational movement of goods via various modes of transport, as well as the management of warehouses, warehouse complexes, and delivery networks. Urban postal logistics is becoming gradually more important as the urban population and e-commerce are increasing. Efficient and sustainable delivery management in narrower city cores is important for the alleviation of traffic congestion, air pollution, and carbon emissions. In addition, it plays a crucial role in enabling fast and reliable delivery of goods to end users and companies. Some key challenges in urban logistics include limited room for warehousing and distribution, traffic congestion, pollution, noise, and gradually shorter expected delivery times. To tackle all these challenges, urban logistic solutions can include alternative transportation options, route and delivery optimization, as well as the application of smart technologies and data analysis. AR (augmented reality) has the potential to make postal-logistic operations more efficient, economical, and safer through the use of real-time data, visualization, and remote assistance. On the road to sustainability, the visualization of operations can be especially useful. This allows logistics managers to better understand the flow of goods and make timely decisions. Equally important is the education of personnel through simulations of technological processes or their parts, and remote assistance, which can engage users through an interactive experience and improve customer satisfaction through a 3D representation of goods in their environment.
