Increased entrepreneurship and an influx of residents to urban areas requires the expansion of the housing and service infrastructure. However, at the stage of construction project implementation, the necessary technical, technological, and transport processes may significantly affect urban logistics and residents’ lives. A literature review showed that there is no exhaustive research on this topic. Therefore, the authors aimed to assess the impact of residential and non-residential (commercial) construction projects carried out in Szczecin on residents’ quality of life. The research process was based on an inductive approach, which enabled conclusions to be drawn in this research area. For this purpose, structured observations and expert consultations as well as surveys related to construction projects were carried out. The research result was the identification of areas related to construction project implementation that have a significant impact on quality of life, which may serve as a basis for preparing city development plans by local authorities.

The share of road vehicles in urban transport systems is a challenge for modern and dynamically developing urban areas in accordance with the concept of sustainable and Smart Cities. Increasingly, there is a need to promote and adapt urban space to the movement of vulnerable road users (VRU). As part of a clear emphasis on the issue of pedestrians and other vulnerable road users, the aim of the article is to define the typology and hierarchy of solutions contributing to the increase in VRU safety in cities. The research process was based on the use of grounded theory. In the adopted research methodology, the use of the Delphi method made it possible to identify the approach of various European cities to the use and implementation of technical, technological and organizational solutions affecting safety. The research made it possible to evaluate individual solutions in VRU safety management and to indicate a list of recommendations for improving security, taking into account the views of international experts. In addition, the results of this study may enrich the current literature, helping to understand the perception of solutions implemented in urban transport systems as a holistic set of interrelated elements supporting pedestrian safety and increasing their role in cities.

Modern cities are places where the ever-increasing human needs are met. This is possible through the creation of friendly living conditions and enabling economic exchange, as a result of which enterprises provide their clients with goods and services. Urban freight transport is an element that supports these processes. However, in addition to the benefits it delivers, its organization and impacts pose challenges in environmental, economic, and social terms. Implementation of construction projects is a determinant of the development of modern cities. However, this entails transport for supply purposes, which significantly affects the volume of freight transport in cities. Such a large share translates into a growing interest in the topic of using more sustainable ways of organizing and providing construction-related transport. The paper presents the first stage of research aimed at building a model for the implementation of good practices in the field of construction supplies. The aim of the paper was to analyze the transport of construction supplies in terms of compliance with the principles of sustainable development on the example of construction projects currently implemented in Szczecin. Furthermore, this paper is centered around collecting good practices in the field of construction transport. The goal was achieved using the analysis of the statistical data, non-structured observation, and surveys regarding construction projects being carried out in Szczecin, and also paper-and-pencil interviews with experts. It was possible to identify irregularities and gaps in knowledge in the field of sustainable urban freight transport for the implementation of construction supplies. The diagnosed current condition may be a significant source of problems in the future and clearly indicates the need for further research and action by both city authorities and enterprises in the direction of implementing measures for sustainable urban freight transport. As part of the paper, the possibility of using Petri nets in decision-making processes on the implementation of selected organizational solutions contributing to a more sustainable organization of construction supplies was also examined. The developed decision models were simulated in the HPSim software. Models created by the authors using Petri nets can be an important tool that clearly and transparently shows enterprises their possibilities in the implementation of good practices.

The development of modern cities is impossible without an increase in the number of construction projects implemented. However, in the conditions of limited spaces, local and national legal regulations, and logistic difficulties, their implementation is becoming a growing challenge. Construction supplies can pose a particular problem. Its planning, organization, and implementation have an impact not only on construction and assembly works, but also on the external environment of the construction site, of which traffic is an important element. The aim of the study was to analyze and answer the question of whether there is a connection between the implementation of construction supplies and the occurrence of road traffic hazards in cities on the example of Szczecin. In addition, the article aims to find solutions to reduce the number of road accidents and increase road safety. The conducted research also revealed the weak points of the system of collecting and analyzing data on road accidents. The research covered selected areas in the center of Szczecin, where construction projects have been implemented since 2016 and road accidents have occurred. The reference year is the year preceding the start of construction. The research on selected construction projects meeting the criteria, carried out in the article has shown that their implementation may have an impact on the level of safety in the areas adjacent to the construction site. However, the unequivocal statement of such relationship must be supported by extended research, covering a greater number of projects, additional consideration of the number of deliveries for supply purposes, and the characteristics of vehicles involved in road incidents.

The article discusses the process of shaping the quality of freight transport implemented for the needs of construction projects in the context of supply strategies selected by enterprises. Enterprises that carry out construction investments face different types of problems. One of these problems is the functioning of the supply chain. Building supplies as part of this chain are a weak point due to both organizational and quality problems. The article presents an analysis of solutions used in the implementation of construction supplies in the city of Szczecin and an attempt was made to analyze the process of shaping the quality of these deliveries.
