Last-mile logistics is an essential yet highly expensive component of city logistics responsible for many nuisances in urban areas. Mobile access hubs are flexible consolidation and transshipment points aiming at creating more sustainable city logistics systems by dynamically using urban space as logistics facilities. In this paper, we examine the potential of mobile access hub deployments for urban parcel logistics by identifying the impact of design parameters on economic and environmental performance. We propose a mathematical modeling framework and an integer program to assess the performance of mobile access hub deployments, and study the impact of a set of design parameters through synthetic cases and an illustrative case inspired from a large parcel express carrier’s operations. Results indicate design flexibility relative to the location of hubs and pronounced advantages in highly variable environments. The illustrative case shows significant savings potential in terms of cost and time efficiency as well as environmental sustainability. It emphasizes a trade-off between operational efficiency and environmental sustainability that can be balanced to achieve global sustainability goals while being economically sound.

Trees are essential elements of an urban space. The presence of trees in urban areas is not only appreciated as physical attribute, but beyond this, it serves a fundamental function in balancing and conserving urban ecosystem. Especially in tropical countries like Indonesia which receive high levels of solar radiation, trees contribute to the protection of urban areas from the impact of excessive micro-climatic conditions. But, the presence of trees sometimes resulted in the accidents for the residences because of broken branches and human injuries. This situation leads the city to prepare a tree inventory system, which is beneficial in giving the information about tree conditions and thus the information that would be useful for tree maintenance activities. The tree inventory on application for the city of East Jakarta was built for this purpose, comprising a tree inventory and easy access to the database. The application connects the database source with the GIS map, so that the users could retrieve information for each kind of data.

The Impact

The incorporation of sustainable design measures in urban planning and development has been steadily increasing in the recent years. Achieving a sustainable urban environment requires accounting for the economic, environmental and social impacts of the development involved. An important factor affecting the social and environmental sustainability of urbanised areas which is commonly overlooked in urban planning is the noise pollution level. Despite the proven impacts of noise pollution on the general wellbeing of individuals within an urban setting, there remains a lack of systematic methods to integrate the impact of noise within the design of urban areas. This chapter seeks to raise awareness of the issue of noise pollution in urban settings while proposing novel approaches for its incorporation as a design parameter in planning the layout of smart cities.

The Impact

Abstract A generalized nonlinear time-varying, planar dynamic model of bifilar centrifugal pendulum vibration absorbers (CPVA) is proposed. This dynamic model enables fast prediction of vibration reduction performance of any CPVA design considering the impact of absorber rollers, gravity, end stops and translational motion of the system. The modeling framework provides comparative, simultaneous simulation results for numerous different design possibilities, and thus can be used to optimize CPVA designs. The dynamic model is generic and can handle N individually designed absorbers on a rotor with numerous path options ranging from circular to cycloid. Absorbers can be designed to be equally or unequally spaced. In this study, first the dynamic model of the bifilar CPVAs is derived. Then, case studies are provided to showcase the capabilities of the modeling framework. Initially, maximum applicable dynamic torque to a CPVA and vibration reduction performance are investigated by considering the effect of tuning order and different absorber path options for different operating speeds. Then, impact of different modelling features on system frequency response and limit dynamic torque is investigated. Interactions between the important design parameters are highlighted. Finally, the influence of end stop positioning on the CPVA dynamic response is illustrated.

The differences in plant phenology between rural and urban areas are the subject of research conducted all over the world. There are few studies aimed at assessing the impact of the urban heat island on plant vegetation only in urban areas. The aim of this study is to assess the impact of the distance from the city center and the form of land cover on the phenological development of trees using the example of the horse chestnut (Aesculus hippocastanum L.). The research area covered the entire city of Wrocław. In order to best capture the impact of the distance from the city center on the rate of changes of individual phenophases, 3 areas were designated—at a distance of 1 km, 2 km and 5 km. The study assessed the average duration of individual phenological phases along with the variability characteristics for leafing, flowering and fruiting in relation to the designated zones and classified forms of land cover based on mean value (x¯) and standard deviation (±SD) in individual weeks of the year. For the leafing and flowering phases, the frequency of the occurrence of phases in individual weeks of the year was analyzed in relation to the designated zones and classified land use methods. The results obtained on the basis of phenological observations carried out in 2017 in Wrocław confirmed the extension of the period of vegetation in the city center in relation to its peripheries. Trees growing in road lanes entered the vegetation period later and defoliated faster, which confirms the negative impact of street conditions on the development of trees in urban space. Thus, the growing season in road lanes is shorter and due to the 1-year observation period, it is justified to conduct further observations.

The aim of this paper is to assess the relationship between the price of accommodation and the urban space and character of the place. The price and spatial connections (together with the quality of the provided services) become an important motive for clients when choosing a concrete accommodation establishment. As the competition is very difficult in the field of accommodation establishments and the supply multiply surpasses the demand, there is an intensive search for miscellaneous strategies of engaging in the competition. The built-up territory of the town České Budějovice was chosen as a model territory. The prices of the summer season 2012 have been entered into the analysis. The impact of the location was assessed on the level of the type of land-use. The distribution of the accommodation establishments in the studied is highly uneven, without any more significant tendency to the creation of the spatial clusters. It is fundamentally influenced especially by the distance of the historical center. A price map was formed identifying the zones with the above-average prices, as well as the zones with the highly below-average prices.

The present sustainable metropolitan cities and the urban planning procedures in Libya are mainly aimed at reducing the impact on the environment due to the use of resources and improving life quality. Thus, the primary objective of this investigation is to create a model that focuses on reliable and valid urban planning of sustainable development, which highly reflects the Islamic way of live concerning the Libyan cities. The projected study model was tested experimentally using a review of 307 suitable samples, which included urban planning associated parties/industries, like the governmental institutions, academic research institutes, developer consultants, and planning and design engineers. Moreover, evaluations were done using the statistical software package Smart-PLS 2.0. The outcome shows that Libyan urban cities should comprise four major elements: social sustainability, environmental sustainability, economic sustainability, and institutional markers. The indicators for every element are studied in detail later in this investigation, which contributed significantly to gaining a better insight into the model for urban planning of sustainable development concerning the Libyan cities. The results provide useful insights for the urban planning industry in order to introduce the UPSD (Urban Planning of Sustainable Development) model, which is helpful as a strategy for Libyan organizations, urban planning contribution, and development to improve Libyan cities. Also, UPSD can be used to assess developed urban areas to analyze the quality of those areas and finally indicate the areas of enhancement.

The Impact

Urban landscape is largely characterized by high degree of built space, high share of artificial surface material and the reduction of green areas, which leads to changes in the microclimate and the deterioration of thermal comfort in out-door urban space. One of the most important roles of urban greenery is the impact on the reduction of air temperature due to less heating of green space com-pared to paved surfaces and due to tree shading. The paper analyses the influence of urban greenery on temperature reduction. Aim of the study was to measure the difference in warming up of grassy surfaces and paving materials commonly used for public areas and to evaluate the impact of tree shading on the surface cooling during the day. For this purpose, measuring of surface temperatures was performed during the summer months in 2015 in the central city zone of the city of Nis. The measuring included: grass, asphalt as most commonly used paving material, and concrete tiles commonly used for pedestrian areas. Results show the temperature of grass is significantly lower than the temperature of paved surface at any time of day. In the case of paved surfaces, temperature of shaded or partially shaded material is lower than the temperature of surface exposed to sunlight during the whole day, a temperature difference exists even after nocturnal cooling. The results indicate the importance of green areas for cooling of urban spaces, due to their lower warming and surface shading from tree canopy.

The Impact

Consumers in large cities are projected to contribute 81% to global consumption in 2030 with B2C e-commerce sales growth projected to increase globally by 24% in 2020. The inquiry of the present study is to understand the impact of this growth on the urban landscape. Three key areas influenced by e-commerce which in turn impact the urban landscape, city logistics, warehousing, and retail experience. Rising home deliveries impact city logistics where delivery trucks contribute to traffic congestion and environmental hazards. E-commerce influences locational demand for warehouses differently, depending on the section of the logistic chain. The positive gains include reduced damage to road infrastructures and higher valuation of logistics real estate in urban areas. The final area, retail experience, influences the sustainability of malls in urban areas. Malls in urban centers could remain relevant by reconfiguring retail spaces to accommodate temporary guide stores and pop-up stores instead of anchor tenants.
