Abstract Background: Urban public sports space, including parks and sports facilities, has captured much public attention because of its close correlation with public health. However, few studies have assessed the equity of accessibility to various types of public sports space comprehensively with a fine scale. Methods: This study proposed a spatial equity measurement method based on multi-source urban data and GIS network analysis. Residential buildings were taken as the minimum research unit to investigate the equity differences of residents' enjoyment of urban public sports space accessible by walking and public transportation. Taking Harbin, China as an example, in the concepts of life circle, this study calculated and visualized the equity of more than 12, 000 residential buildings to a variety of public sports space in the central urban area. Results: The results showed that: 1) There was obvious inequity of sports space in the central city. The results under classification varied sharply, while the overall results moderated to a certain extent. 2) There were sharp differences between different types of sports space, and square space had the worst structure of equity. 3) The results of the two traffic modes were significantly correlated, and the correlation coefficient of the comprehensive results was the largest. In areas with poor walking equity, the results of the bus mode were generally not high either. Conclusion: This study integrated multi-source data into the traditional spatial computing models and provided an important reference for the equitable planning of urban public sports space. Attention should still be paid to the characteristics of the population in the planning intervention, such as the preference for public sports space and the limitation of choice caused by age difference. The closer the research is to the human scale, the more scientific the planning may be.

Section 8 Housing

The controversial Section 8 Housing Choice Voucher program is the largest federal low-income housing program. Using GIS-based spatial clustering analysis (Getis–Ord’s Gi statistic) and multiple linear regressions, in this paper, the authors examine the locational patterns of more than 13,600 Section 8 housing units in Jefferson County, Kentucky, and explore key social, economic, demographic, and locational factors underlying the spatial distribution of Section 8 housing. The findings reveal that Section 8 housing continues to concentrate in the central city area with predominantly black residents, a high proportion of families in poverty, and abundant low-cost properties. The Section 8 voucher policy has failed to successfully de-concentrate poor families from these urban areas. Residential mobility of low-income families has been restricted by various factors, most important of which is the lack of accessibility to public transportation across the metropolitan area.

High residential living in Malaysia has not been widely given a significant emphasises in literature despite its increasing scale and significance in the real estate market. The significance of high rise is mainly due the increasing rate of migration from rural to urban. It is estimated a total of 77.2 percent of the Malaysian population lived in urban areas in 2020. Approximately, 30 percent of this urban population lives in strata housing. These percentages are predicted to continue to increase in the future. The emergence of high residential building has been argued as confronting various problems which has considerable impact on this life style. Satisfaction is an important outcome of living in one’s dwelling, although it is not the only consideration. High residential building in Malaysia encountered numerous problems in term of management aspects, legislation aspects, and residents’ satisfaction. The purpose of this paper is to investigate the tenants’ satisfaction living in high residential buildings in Klang Valley. The questionnaires survey is conducted amongst 276 tenants at low cost and medium cost HRB using random sampling in HRB located at areas under jurisdiction Dewan Bandaraya Kuala Lumpur (DBKL), Majlis Bandaraya Subang Jaya (MBSJ), Majlis Bandaraya Shah Alam (MBSA), Majlis Bandaraya Subang Jaya (MBSJ), Majlis Perbandaran Selayang (MPS) and Majlis Perbandaran Ampang Jaya (MPAJ). The result from this study shows that tenant in medium cost residential building are more satisfied in term of facilities and management as compared to tenants in low cost residential building. Tenants also not disclosed to the existing act and procedure related to high residential building. In conclusion, this study suggested the Local Authority to emphasise the role of tenant. These recommendation hopefully will increase the level of satisfaction amongst the residents in HRB.

Abstract Background This paper provides insight into the opportunity offered by shared autonomous vehicles (SAVs) to improve urban populations’ spatial equity in accessibility. It provides a concrete implementation model for SAVs set to improve equity in accessibility and highlights the need of regulation in order for SAVs to help overcome identified spatial mismatches. Methodology Through the formulation of linear regression models, the relationship between land-use and transportation accessibility (by car and public transport) and socio-economic well-being indicators is tested on district-level in four European cities: Paris, Berlin, London and Vienna. Accessibility data is used to analyse access to points of interest within given timespans by both car and public transport. To measure equity in socio-economic well-being, three district-level proxies are introduced: yearly income, unemployment rate and educational attainment. Results In the cities of Paris, London and Vienna, as well as partially in Berlin, positive effects of educational attainment on accessibility are evidenced. Further, positive effects on accessibility by yearly income are found in Paris and London. Additionally, negative effects of an increased unemployment rate on accessibility are observed in Paris and Vienna. Through the comparison between accessibility by car and public transportation in the districts of the four cities, the potential for SAVs is evidenced. Lastly, on the basis of the findings a ‘SAV identification matrix’ is created, visualizing the underserved districts in each of the four cities and the need of equity enhancing policy for the introduction of SAVs is emphasized.

Building Energy Use

As the population of urban areas continues to grow, and construction of multi-unit developments surges in response, building energy use demand has increased accordingly and solutions are needed to offset electricity used from the grid. Renewable energy systems in the form of microgrids, and grid-connected solar PV-storage are considered primary solutions for powering residential developments. The primary objectives for commissioning such systems include significant electricity cost reductions and carbon emissions abatement. Despite the proliferation of renewables, the uptake of solar and battery storage systems in communities and multi-residential buildings are less researched in the literature, and many uncertainties remain in terms of providing an optimal solution. This literature review uses the rapid review technique, an industry and societal issue-based version of the systematic literature review, to identify the case for microgrids for multi-residential buildings and communities. The study describes the rapid review methodology in detail and discusses and examines the configurations and methodologies for microgrids.

Ongoing urbanization leads to steady growth of urban areas. In the case of highly dynamic change of municipalities, due to the rates of change, responsible administrations often are challenged or struggle with capturing present states of urban sites or accurately planning future urban development. An interest for urban planning lies on socio-economic conditions, as consumption and production of disposable goods are related to economic possibilities. Therefore, we developed an approach to generate relevant parameters for infrastructure planning by means of remote sensing and spatial analysis. In this study, the single building defines the spatial unit for the parameters. In the case city Belmopan (Belize), based on WorldView-1 data we manually define a city covering building dataset. Residential buildings are classified to eight building types which are locally adapted to Belmopan. A random forest (RF) classifier is trained with locally collected training data. Through household interviews focusing on household assets, income and educational level, a socio-economic point (SEP) scaling is defined, which correlates very well with the defined building typology. In order to assign socio-economic parameters to the single building, five socio-economic classes (SEC) are established based on SEP statistics for the building types. The RF building type classification resulted in high accuracies. Focusing on the three categories to describe residential socio-economic states allowed high correlations between the defined building and socio-economic points. Based on the SEP we projected a citywide residential socio-economic building classification to support supply and disposal infrastructure planning.

Acidification processes in western North America will probably increase in scope and visibility over the foreseeable future. Localized acidification seems more probable for the next few decades than does a generalized acidified deposition over the western States. At least part of current acid deposition downwind of urban areas is associated with automobile emissions. However, increases in coal combustion for power generation might be expected to increase sulphur dioxide concentrations, along with several related acidifying agents. Interactions of air pollutants with orographic precipitation and snowmelt may bring some areas to public attention much earlier than others, depending upon site-specific matters of climate, topography, soils, water-bodies, and biota. Lakes and streams on windward slopes facing large urban or industrial sources of sulphur and nitrogen oxides may be most seriously at risk.

The Living Bot is a project where future residential buildings will adapt to the times. In the coming year, the human population will continue to grow, so that it will use the land as a place for various needs such as shelter, activities, and other things. Along with this increase in human population, the land will also shrink while the land itself is needed so that humans can meet their food needs either from farming (plants), or through livestock (animal). Therefore, The Living Bot created a system in which human implementation begins to adapt to the life in which they live by implementing a residential system that can produce their own food with plantings that maximize vertical land. This form of shelter can be used as a system so that its application can be carried out. Adaptations that are carried out are by changing the lifestyle of humans to the use of technology. The lifestyle that must adapt is by farming, assisted by A.I. technology. because humans in urban areas do not have a background in growing a food crop. Therefore technology is present in helping urban communities, also assisted by modern planting methods such as using hydroponics, aquaponics, aeroponics, and indoor planting techniques assisted by artificial light such as LEDs. Keywords: Adaptation; Techonology Abstrak The Living Bot merupakan sebuah proyek dimana bangunan hunian pada masa depan akan beradaptasi dengan perkembangan zaman. Pada tahun yang akan datang, populasi manusia akan terus bertambah, sehingga akan menggunakan lahan sebagai tempat untuk berbagai macam kebutuhan seperti tempat tinggal, aktivitas, dan hal lainnya. Seiring dengan pertambahan populasi manusia ini, lahan juga akan semakin menyempit sedangkan lahan sendiri diperlukan agar manusia dapat memenuhi kebutuhan pangannya baik dari hasil bertani (tumbuh-tumbuhan), ataupun melalui peternakan (hewani). Maka dari itu The Living Bot membuat suatu sistem yaitu dimana implementasi manusia mulai beradaptasi dengan kehidupan tempat tinggalnya dengan menerapkan sistem hunian yang dapat menghasilkan makanannya sendiri dengan penanaman-penanaman yang memaksimalkan lahan secara vertikal.Bentuk hunian seperti ini dapat dijadikan sebuah sistem sehingga penerapannya dapat dilakukan di berbagai hunian Adaptasi yang dilakukan adalah dengan mengubah gaya hidup manusia sampai kepada pengunaan teknologi. Adapun gaya hidup yang harus beradaptasi adalah dengan bercocok tanam, dengan dibantu oleh teknologi A.I. karena manusia yang ada di perkotaan tidak memiliki latar belakang dalam menanam sebuah tanaman pangan. Maka dari itu teknologi hadir dalam membantu masyarakat kota, juga dibantu oleh metode menanam yang modern seperti menggunakan hidroponik, akuaponik, aeroponik, dan teknik penanaman indoor yang dibantu oleh cahaya buatan seperti LED.

<p>The present paper relates to the design of a cable-stayed footbridge, composed by ready made elements and with span suitable to various urban and building areas. At present, in order to find a solution to traffic problems, local governments look for many ways to alleviate city’s main roads, increasing public transportation and designing dedicated underground pedestrian routes. Although this subways already built are not really used by pedestrians, which prefer wide-open spaces, such as skyways also designed for people with reduced mobility. In this context the described footbridge, with access ramps designed in accordance with accessibility standards, represents not only a good solution for cycle and pedestrian mobility problems, but it is also easy to transport and to be installed, due to its modular elements. The access ramps are suspended to pilons with inclination depending by the required bridge lengths and they can be assembled in different configurations in order to be well integrated also in limited space areas. Finally a particular focus is dedicated to cables, with dismountable end terminations designed to reduce transportation space and costs</p>

AbstractWhen a disaster such as a large earthquake occurs, the resulting breakdown in public transportation leaves urban areas with many people who are struggling to return home. With people from various surrounding areas gathered in the city, unusually heavy congestion may occur on the roads when the commuters start to return home all at once on foot. In this chapter, it is assumed that a large earthquake caused by the Nankai Trough occurs at 2 p.m. on a weekday in Osaka City, where there are many commuters. We then assume a scenario in which evacuation from a resulting tsunami is carried out in the flooded area and people return home on foot in the other areas. At this time, evacuation and returning-home routes with the shortest possible travel times are obtained by solving the evacuation planning problem. However, the road network big data for Osaka City make such optimization difficult. Therefore, we propose methods for simplifying the large network while keeping those properties necessary for solving the optimization problem and then recovering the network. The obtained routes are then verified by large-scale pedestrian simulation, and the effect of the optimization is verified.
