Understanding the dynamics by which urban areas attract visitors is important in today’s cities that are continuously increasing in population towards higher densities. Identifying services that relate to highly attractive districts is useful to make policies regarding the placement of such places. Thus, we present a framework for classifying districts in cities by their attractiveness to daily commuters and relating Points of Interests (POIs) types to districts’ attraction patterns. We used Origin-Destination matrices (ODs) mined from cell phone data that capture the flow of trips between each pair of places in Riyadh, Saudi Arabia. We define the attraction profile for a place based on three main statistical features: The number of visitors a place received, the distribution of distance traveled by visitors on the road network, and the spatial spread of locations from where trips started. We used a hierarchical clustering algorithm to classify all places in the city by their features of attraction. We discovered three main types of Urban Attractors in Riyadh during the morning period: Global, which are significant places in the city, Downtown, which contains the central business district, and Residential attractors. In addition, we uncovered what makes districts possess certain attraction patterns. We used a statistical significance testing approach to quantify the relationship between Points of Interests (POIs) types (services) and the patterns of Urban Attractors detected.

In developing countries, rapid urbanization has created an enormous pressure on land use, infrastructure and transportation. The fast growing ratio of motorized vehicles in urban areas is the main cause of environmental degradation. Almost 80% of the greenhouse gas emission is from vehicles in cities. In the city centers, on-street parking is considered the major cause of traffic congestion. The aim of this study was to evaluate the problems of on-street parking and disorderly parking at Central Business District (CBD) of Hyderabad city. The field survey methodology was adopted to perceive the current traffic problems in the city center and traffic count survey was carried out in both peak and off hours. The data was analyzed using descriptive statistics frequency analysis technique with the help of Statistical Package for the Social Sciences (SPSS). The findings revealed that increasing number of vehicles, on-street parking, improper parking, encroachment, inadequate parking space and poor condition of roads are the main causes of traffic congestion. The study bridges up the research gap of determining public views about on-street parking challenges in the context of Hyderabad, Pakistan and provides statistical results which may equally be adapted by policy makers and transportation planners in order to improve the traffic situation.

Different types of drivers and parking spaces delineate a heterogeneous parking market for which the literature has yet to provide a model applicable to the real world. The main obstacle is computational complexities of considering various parking restrictions along with traffic congestion on the road network. In this study, the heterogeneity aspects are considered within a Logit parking choice model. A mathematical programming problem was introduced to explicitly consider parking capacities and parking rationing constraints. The parking rationing is defined as any arrangement to reserve parking space for some specific demand such as parking permit, private parking, VIP parking, and different parking durations. Introduction of parking rationing in the presence of other constraints is a unique factor in this study which makes the model more realistic. The algorithm was tested on a central business district case study. The results prove that the algorithm is able to converge rapidly. Among the algorithm’s output are shadow prices of the parking capacity and parking rationing constraints. The shadow prices contain important information which is key to addressing a variety of parking issues, such as the location of parking shortages, identification of fair parking charges, viability of parking permits, and the size of reserved parking.

Abstract Due to the increased tendency to use private transport in urban areas of Manizales and Villamaría municipalities, it is intended to include alternative modes of transport that are more time-efficient and environmentally sustainable to improve the inhabitants’ quality of life. This article aims to analyse the inclusion impact of a sustainable public transport system, such as a new cableway line in the city connecting the Central Business District (CBD) with Ciudadela del Norte district, measuring overall average accessibility for the current and future scenario. This establishes the average travel time and the savings in terms of time shown as a percentage that these modes of transport would create in the population displacement and also which inhabitants are the most likely to benefit.

Depth Interviews

This research is motivated by the many irregularities that occur in urban areas such as the city of Semarang, for example the number of street children. This observation is done by jumping directly to the destination that is on Sambiroto Street, Semarang. There are various kinds of jobs for street children who sell newspapers, provide services to wipe the windshield when passing on the street and sell newspapers. The purpose of this observation is to find out what lies behind these children or adolescents as street children, and to study and analyze internal factors, such as within the scope of the family that makes them street children. To find out their work while on the streets, whether they work for themselves or told by others. The method used in this observation is using qualitative methods. Data collected by in-depth interviews, observation, and documentation. After the data has been collected, data analysis is carried out through the stages, namely data reduction, data presentation and conclusion drawing. The results of these observations show that the main factor that caused them to go to the streets is because of the family's economic limitations, so they voluntarily or with their own initiative to go into the streets by working on the streets. While on the road they often interact with other street children so that they eventually form a group or even a community. Interaction is woven for a specific purpose such as working together when plunging into the road.

Cities in Indonesia were initially formed through the transformation of various influences of power and power. Strength as an identity that can attract the outermost area to come to an area, while power lies in the personal strength of man as the leader of a region. These conditions have an impact on the development of the world of industry in the country. Transforming traditional city structures into a modern city, not only physically but also a basic transformation towards the concept of urbanity of its citizens. The urban village as an element of the city which is the identity of a region, still holds a traditional urbanity value system that is different from the conception of modern urbanity. This condition affects the development of industrial zones, such as what happened in Bajera Village, Selemadeg District, Tabanan Regency. The heterogeneity of the population of Bajera Village is one of the biggest indicators of the formation of an industrial zone. The existence of a transportation mode that connects the outermost areas of Bajera with the Core of Bajera Village is another driving factor that influences the growth of industrial estates. This study tried to explain descriptively qualitatively, a fact of regional development based on Asiatica Euphoria McGee's theory. The special attraction in the core of Bajera Village encourages residents in the outermost areas of Bajera to migrate to the core areas of Bajera Village with the aim of staying temporarily and to settle for long periods of time. This phenomenon is in line with the theory put forward by McGee, that the CBD (central business district) is formed due to the attraction of the core (core) and the ease of modes of transportation from peri urban areas to the CBD. This condition makes Bajera village the center of industrial and trade areas in the Selemadeg Barat region, Tabanan, Bali.

Urban areas experience exacerbated impacts of the regional climate variability because of their form characteristics such as imperviousness of surfaces, building density and distribution of open spaces. These are further confounded by geographical aspects such as topography, soil types, and vegetation types. Nairobi city is increasingly exposed to flood and heat risk as an aggregation of its urban form and the changing global climate. The paper sought to establish the influence of Nairobi’s biophysical characteristics on its vulnerability to both flooding and heat risks. The paper used a descriptive research design augmented with Geographic Information Systems to spatially model the landcover, soil drainage, topography, green space networks, and population density characteristics at the sub-location level. Vulnerability indices were developed using the expert ranking system and used to determine the vulnerability of the different sub-locations. The findings revealed a vulnerability pattern close to the historically segregated planning of the city. The central and eastern parts of the city exhibit high vulnerability while the western, northwestern, and southern parts of the city display moderate to low vulnerability. The paper recommends that adapting existing neighbourhoods and proactive planning of new neighbourhoods uses the ecosystem-based approach. This to entail decentralization of smaller green spaces, redesign of road medians for water management, re-specification of street vegetation species to incorporate a mix of deciduous and evergreen trees and incorporating eco-roofs and walls in high-density developments like the Central Business District.

Gelendzhik is the resort town, there aren't a lot of industrial enterprises here. The main pollutant is transport. The work purpose is the assessment of a condition of the artificial landings of a pine located along the Federal highway "Don" and landings, which is nearly the sea coast. Researches were conducted to a standard technique of the General vital state (A. S. Bogolyubov). The assessment of a condition of pines was carried out during 6 years: from 2010 to 2015. For carrying out research we used 6 experimental grounds on the Markotkhsky spine and 2 control grounds within the town. We investigated 24 trees on each platform, middle age of the trees were 30 - 40 years. Results. 1. The condition of trees in the pine forests located in immediate proximity with the Federal highway "Don" (No. 1, 2, 3) is unsatisfactory. As even weak influences of the majority of atmospheric gaseous pollutants (sulphurous gas, nitrogen oxides, etc.) give effect of a necrosis and hloroz of pine needles, the condition of pines is connected with technogenic pollution. So near the Federal highway "Don" the air environment is strongly polluted by exhaust gases. Information of 2012 confirm that negative influence of the route on Markotkh's vegetation decreases at reduction of load of the route. 2. On the sites located above on a slope (No. 4,5,6) thanks to remoteness and the wind mode intensity of influence of pollutants is lower and a condition of pines the quite satisfactory. 3. Trees on the sites located near the sea (No. 7,8) are in a good shape. Small deterioration of a state is noted in very droughty years. Conclusion. Results of six years' research show that the condition of the plantings which are in close proximity with the road worsens. It is explained by increase in intensity of the movement on the road, especially during a resort season. Gelendzhik is the city with a good ecological shape, but the damage to environment is already caused. If not to take measures, we can lose a unique part of the nature in the future, recreate it will be impossible. Measures of reduction of negative impact of exhaust gases were offered. Results of researches are transferred to ecological department of the City administration of Gelendzhik.

As a promising topic of research, Vehicular Cloud (VC) incorporates cloud computing and ad-hoc vehicular network (VANET). In VC, supplier vehicles provide their services to consumer vehicles in real-time. These services have a significant impact on the applications of internet access, storage and data. Due to the high-speed mobility of vehicles, users in consumer vehicles need a mechanism to discover services in their vicinity. Besides this, quality of service varies from one supplier vehicle to another; thus, consumer vehicles attempt to pick out the most appropriate services. In this paper, we propose a novel protocol named RSU-aided Cluster-based Vehicular Clouds protocol (RCVC), which constructs the VC using the Road Side Unit (RSU) directory and Cluster Head (CH) directory to make the resources of supplier vehicles more visible. While clusters of vehicles that move on the same road form a mobile cloud, the remaining vehicles form a different cloud on the road side unit. Furthermore, the consumption operation is achieved via the service selection method, which is managed by the CHs and RSUs based on a mathematical model to select the best services. Simulation results prove the effectiveness of our protocol in terms of service discovery and end-to-end delay, where we achieved service discovery and end-to-end delay of 3 × 10−3 s and 13 × 10−2 s, respectively. Moreover, we carried out an experimental comparison, revealing that the proposed method outperformed several states of the art protocols.

Abstract Introduction Cervical cancer and its etiopathogenesis, the age of women in whom it is diagnosed, average life expectancy, and prognosis are information widely covered in scientific reports. However, there is no coherent information regarding which regions—urban or rural—it may occur more often. This is important because the literature on the subject reports that people living in rural areas have a worse prognosis when it comes to detection, treatment, and life expectancy than city dwellers. Material and methods The subjects of the study were women and their knowledge about cervical cancer. The research was carried out using a survey directly distributed among respondents and via the Internet, portals, and discussion groups for women from Poland. Three hundred twenty-nine women took part in the study, including 164 from rural and 165 from urban areas. The collected data enabled the following: (1) an analysis of the studied groups, (2) assessment of the respondents’ knowledge about cervical cancer, and (3) comparison of women’s knowledge depending on where they live. Results The average assessment of all respondents’ knowledge was 3.59, with women living in rural areas scoring 3.18 and respondents from the city—4.01. Statistical significance (p < 0.001) between the level of knowledge and place of residence was determined. The results indicate that an increase in the level of education in the subjects significantly increases the chance of getting the correct answer. In the case of age analysis, the coefficients indicate a decrease in the chance of obtaining the correct answer in older subjects despite the fact that a statistically significant level was reached in individual questions. Conclusions Women living in rural areas have less knowledge of cervical cancer than female respondents from the city. There is a need for more awareness campaigns to provide comprehensive information about cervical cancer to women in rural areas. A holistic approach to the presented issue can solve existing difficulties and barriers to maintaining health regardless of the place of life and residence. Implication for cancer survivors They need intensive care for women’s groups most burdened with risk factors.
