Content available Sustainable construction supplies in modern cities
EN
The implementation of construction projects largely determines the development of modern cities. However, such projects impact both urban freight transport and residents. To reduce this impact, increasingly more attention has been paid to the issues of sustainable development. Sustainable urban freight transport has become a priority for European cities. It also contributes to construction supplies. This article presents the results of analyzing construction supplies and the assessment of their compliance with the principles of sustainable development using the example of the city of Szczecin. This allows for the diagnosis of problems in this area, and solutions in the field of sustainable construction are collected. The presented research includes unstructured observation of construction projects in progress, structured interviews with entities implementing construction projects in Szczecin, and additional expert research to identify solutions in the field of sustainable construction supply in cities. This enables the research objective to be achieved and conclusions to be developed.

Unloading bays are one of the most popular and simple to implement solutions to support development of sustainable urban freight transport systems. The solution is aimed at reducing congestion on busy city streets, which is often caused by freight vehicles that, in an attempt to load or unload their cargoes, park directly in traffic lanes. Where dedicated unloading bays are in place, the traffic is undisturbed, which helps to prevent extra consumption of energy and fuel, and thus extra pollution, and which also makes it possible to avoid wasting time in traffic jams and ensuing costs. Therefore, the major benefit derived from this solution is its contribution to reduction of traffic congestion, followed by a perceptible decrease in pollutant emissions. This article aims at developing an algorithm for recommended distribution of unloading bays based on the reported locations of delivery points and parameters related to varied quantities of goods and the number of available parking spaces in the vicinity of unloading bays. Additionally, it addresses the issue of using unloading bays as EV charging stations. The proposed solution was implemented on the basis of a dedicated road traffic simulator based on the original cellular automaton model..

Roads and parking areas represent a place of conflict between freight vehicles and other urban activities, especially on mixed residential and commercial streets. This conflict results in traffic congestion, illegal parking, pollution and road safety problems. The challenge is to allocate public space between the right operating activities, parking activities, public transport and so on. To address that, urban logistics delivery bays, also known as loading/unloading (L/U) zones, have become a real solution to facilitate the delivery and pick-up operations of urban freight vehicles, ensure accessibility for delivery drivers, reduce congestion and improve road safety. Therefore, this paper reports on planning and enforcement of urban delivery bays needs. It is part of the urban freight transport (UFT) surveys. This involves consolidating with new contribution the development, implementation and statistical analysis of a survey in order to quantify the need of delivery areas. Compared to the existing literature, this paper presents a mixed applied methodology which is divided into two parts : “Exploratory survey” and “Establishment vehicle observation” survey. These two surveys techniques were conducted to offer an overview of the freight vehicle delivery and pick-up frequency according to the daytime and weekdays and the operations related to the loading/unloading activities. This makes it possible to estimate the delivery bays requirement in the study area. The findings from a methodological and practical angle are illustrated through a real case study in a commercial street in Morocco. The findings suggest that 60% of deliveries are made between 8:00 A.M and 12 A.M, and the movements generated by each establishment are 257 movements. For this, the study zone requires the development of three loading/unloading (L/U) bays. The main contribution is to propose an approach that urban authorities can use to estimate urban delivery areas efficiently and thus allow simple replication of the proposed framework in other cities.

Transport towarów miejskich ma istotny wpływ na życie mieszkańców oraz funkcjonowanie lokalnej gospodarki. Wytwarza jednocześnie liczne problemy związane z oddziaływaniem na środowisko i otoczenie. Dystrybucja towarów w mieście ma więc znaczący wpływ na życie mieszkańców i na wrażenia turystów. Z uwagi na fakt, że 25 proc. emisji pochodzących z transportu w UE pochodzi z obszarów miejskich, miasta odgrywają kluczową rolę w łagodzeniu negatywnych skutków transportu. Wiele miast wdraża obecnie Plany Zrównoważonej Mobilności Miejskiej (ang. Sustainable Urban Mobility Plan, SUMP), które skupiają się na mobilności ludzi. W większości przypadków dystrybucja towarów nie jest poruszana w SUMP lub jest zdawkowo wspomniana. W przypadku braku jasnych wytycznych dotyczących rozwiązywania kwestii transportu miejskiego, niektóre miasta przyjęły różnorodne strategiczne dokumenty i środki. Przy braku standaryzacji dokumentów, trudno jest je porównywać i ustalać poziom zaawansowania miasta we wdrażaniu środków logistyki miejskiej. Aby przezwyciężyć ten problem, KE zainicjowała koncepcję Planów Zrównoważonej Logistyki Miejskiej (ang. Sustainable Urban Logistics Plan, SULP). W artykule zaprezentowano strukturę i plan wdrażania SULP.

Transport of urban goods has a significant impact on the lives of residents and the functioning of the local economy. At the same time, it creates numerous problems related to the impact on the environment and the surroundings. Thus, the distribution of goods in the city has a significant impact on the lives of residents and tourists' impressions. Due to the fact that 25 percent EU emissions from transport come from urban areas, cities play a key role in mitigating the negative effects of transport. Many cities are currently implementing Sustainable Urban Mobility Plan (SUMP) that focus on people's mobility. In most cases, the distribution of goods is not mentioned in the SUMP or is mentioned briefly. In the absence of clear guidelines for resolving urban transport issues, some cities have adopted various strategic documents and measures. In the absence of standardization of documents, it is difficult to compare them and determine the level of city advancement in the implementation of urban logistics measures. To overcome this problem, the EC initiated the concept of Sustainable Urban Logistics Plan (SULP). The article presents the structure and plan of implementing SULP.

Transport is one of the main sectors of the economy, which has a significant impact on the economic development. Efficient transport systems are the basis of economic competitiveness. However development of transport, especially in the case of road transport, results many inconvenience, like negative environmental impact, accidents or increase of congestion in cities. From the perspective of sustainable development the most important one is pollution. Depending on the type of emitted substances, transport pollution is of local or global nature. Considering the emission of pollutants in urban areas, emitted toxic compounds mainly impact the local pollution the environment. This paper is focused on utilization of Internet tools for visualization of data regarding local pollutions in urban transport systems. This is the example of tool, which could be helpful in analysis of present functioning of UFT

The paper addresses the problem of the reconstruction and allocation of delivery positions in the urban area. The aim is to achieve the optimal reorganization of urban freight transport in old town core in the municipality of Celje. Optimal allocation relies on optimization based on the Monte Carlo simulation and represents a first stage of a two-stage optimization approach to re-design the existing urban freight transport. The number of optimal delivery positions is required to be as minimal as possible, which can still assure a maximal service area within the prescribed radius, while keeping the minimal walking distances of delivery personnel between the nearest delivery position and the customer’s physical location. The main issues of the used heuristic allocation algorithm and the presentation of calculated results are provided. In the near future, the calculated delivery positions are going to be used for the purpose of physical implementation in order to improve the existing delivery transport.

Postęp cywilizacyjny, otwarcie granic oraz globalizacja przyczyniły się do rozwoju procesów urbanizacyjnych. Obecnie w miastach europejskich zamieszkuje ok. 40% ludności. Przewiduje się, że do 2050 roku na świecie miasta zamieszkiwać będzie ok. 2/3 całej populacji. Rosnąca liczba mieszkańców miast prowadzi do zwiększenia zapotrzebowania na przewozy różnych towarów, m.in.: surowców, półfabrykatów, wyrobów gotowych oraz odpadów przemysłowych i komunalnych. Miasta są miejscem pracy, zamieszkania, wypoczynku, dokonywania zakupów, a także korzystania z dóbr kultury. Powinny mieć zatem, oprócz ekonomicznego, także wymiar społeczno-kulturowy i ekologiczny. Za najbardziej efektywne działania zrównoważonej polityki transportowej uważa się te, które godzą te trzy aspekty równocześnie, minimalizując koszty związane z osiągnięciem oczekiwanych celów [...] Odpowiedzią na te problemy stały się liczne projekty realizowane przez Unię Europejską, zajmujące się inicjowaniem zmian oraz rozpowszechnianiem wiedzy z tego zakresu. Jednym z nich jest projekt C-LIEGE, którego ogólnym celem jest określenie wspólnej polityki i działań na rzecz efektywności energetycznej transportu towarowego w miastach. Jest on oparty na współpracy między podmiotami publicznymi i prywatnymi, której celem jest zmniejszenie zużycia energii w transporcie towarowym w miastach i regionach UE. Propozycje przedstawione w referacie są rezultatem wstępnych prac badawczych autorek, związanych z realizacją wspomnianego wyżej projektu. Badania są ukierunkowane na podwyższenie jakości życia mieszkańców miast oraz poprawienie warunków funkcjonowania podmiotów gospodarczych poprzez eliminację zbędnych przewozów. Celem artykułu jest ukazanie przykładów, które pozwolą zapewnić nie tylko ekonomiczny, ale także ekologiczny rozwój regionu m.in. dzięki adaptacji rozwiązań już sprawdzonych w Europie.

The development of civilization, free cross-border movement and globalization contribute to development of urban processes. In European cites live c.a. 40% of population and forecasts say that in the year 2050 urban population will grow to the 2/3 of the whole. The result of growing number of metropolitan citizens are growing transportation needs according to materials, semi-finished products, goods, and wastes. Cites are places of living, working, resting, purchasing, and also important places for the culture. We may stand out three the most important aspects: economic, environmental and social. There are many problems connected with them. In economic aspect the most important are: congestion and low efficiency of investments. In environmental: pollution and carbon dioxide emission (increased fossil fuels consumption generate growing number of wastes e.g. tires or gas oils) In the social aspect the most important are healthy problems of population caused not only by pollution but by road accidents as well. They are closely connected with transport infrastructure development. The most effective sustainable freight policy is the one which enables to com.in. all these roles and get expecting results. There are many European projects which try to initiate positive changes in that field by taking innovating actions and ideas diffusion. The example of such program can be the C-LIEGE project whose general aim is to establish a common policy due to improving energy efficiency of urban freight transport. A cooperation between public and business institutions is crucial here. The main goal of the paper is to show examples enabling economic and ecological region growth. To that end in the article authors present an initial researches related to C-LIEGE project which are concentrated on improving lives comfort of metropolitan population and elimination of unnecessary freight transports.

Today, many cities in the world struggle with an increasing demand arising from quick population changes. Most European big cities experience congestions, pollutions, saturations, uncollected waste, public dissatisfaction, and unpleasant environment to work and live in. In order to respond properly and effectively to these phenomena, city authorities are forced to take speedy and right decisions of ensuring good living conditions for all the residents. Reorganizing, rebuilding and enlarging cities is a difficult task which in many cases is on the boundary of impossible because of historical reasons, heritage and preservation of environment. Urban Consolidation, however, might be a good solution. In this paper we introduce urban and urban freight consolidation concepts, where our aim is to identify and reveal missing knowledge to the current state of the art.
