While great progress in the development of a methodological approach to measure the accessibility of healthcare services has been made, the exclusion of the complex multi-mode travel behavior of urban residents and a rough calculation of travel costs from the origin to the destination limit its potential for making a detailed assessment, especially in urban areas. In this paper, we aim to describe and implement an enhanced method that enables the integration of multiple transportation modes into a two-step floating catchment area (2SFCA) method to estimate accessibility. We used a travel-mode choice survey, based on distance sections, to determine the complex multi-mode travel behavior of urban residents. Taking Nanjing as a study area, we proposed complete door-to-door approaches to determine every aspect of basic transportation modes. Additionally, we processed open data to implement an accurate computing of the origin-destination (OD) time cost. We applied the enhanced method to estimate the accessibility of residents to hospitals and compared it with three single-mode 2SFCA methods. The results showed that the proposed method effectively identified more accessibility details and provided more realistic accessibility values.

Abstract Rail-based transportation, namely trains, has an important role for communities in sub-urban areas. By using the train, communities no longer need to use their vehicles. They can change modes with two choice of ways to get to the station, park their personal vehicle or by using shuttle transportation. The concepts of the two-ways is a form of implementation of park-and-ride and kiss-and-ride. This study aims to identify the reasons why KRL users choose park-and-ride or kiss-and-ride facilities and the user spatial patterns of these facilities. The analysis uses the E2-SFCA (Enhanced 2-Step Floating Catchment Area) method by calculating the distance and ratio of station users and then produces an accessibility value. The results of the analysis that have been carried out indicate that the majority of park-and-ride users are spread out in zone 2 and kiss-and-ride users are spread out in zone 1. The catchment area from both stations are predominantly from areas with local road network characteristics. This road network has a high density but limited vehicle speed. The cost and origin of the distance from the place of residence affect the difference in the catchment area of the KRL station.

River Modeling

The quality of river water has been an important issue, due to its significant important function to the human being. In Asia, Malaysia is considered as one of the most speedily urbanizing countries and it’s facing huge environmental challenges. An increased pressure on urban areas has been generated by rapid manufacturing especially in the Penchala River Basin. Penchala River originates from Kiara Hill and passes through several important townships as it flows through residential and industrial areas before meeting with Klang River. Although the river is relatively short, with an approximately 12 km in length with a catchment area of 28 kilometer square, this catchment is noted to be under environmental stress emanating from storm water pollution, solid waste, sedimentation and micro-pollutant. To study the water pollution issue, it is always best if it is tied up with the geographic information system. The objective of this study is to use the GIS for preparing and organizing the geometric data to satisfy the water quality model requirements. As a result of this study, a digital map for Penchala River has been created.

Abstract Community senior centers are tasked with providing aging adults services and programs, congregate meals, and transportation, set forth by the Older Americans Act. The overall function of senior centers is especially critical for rural communities, as rural communities are home to a greater proportion of older adults compared to metropolitan and low-density urban areas. To assess the current needs of the aging population in rural Northwest, OH, a total of 9 focus groups were held (N=45) as part of a larger mixed-methodological study. Through this work, older adults identified limitations of the current senior center transportation. A lack of transportation and accessibility of current transportation were noted as barriers to full senior center use. Findings from this study confirm disparities in rural transportation; a lack of transportation is a major obstacle to program completion. Recommendations address the unique challenges and needs for transportation services for in rural communities are presented.

Urban Water Quality

In the world scenario the contamination of water due to the various reasons is one of the major problems in the urban and semi-urban areas which have both positive and negative impact on the existed environment and also on the quality of human life. The developing activities taking place in and around the urban areas covers soil with concrete which leads to reduced soil recharge capacity at one side and the other side releasing of untreated urban sewage in to nearby open water bodies without any concern became most practicing method in most of the urban areas. The new capital region of Andhra Pradesh is selected as study area which is rapidly developing with commercial and residential built-up area. Due to which the pressure on groundwater is increased rapidly with respect to its quality and the quantity to meet the requirement of the living as well as migrating people from all the corners to the newly developing capital region. If the similar situation continues there will be a severe and irreparable damage to the availability of groundwater for the future generation and also there will be a notable reduction in the living standards of urban people. The present study examines groundwater and surface water quality and compared with water quality standards to determine the status of water quality at study area. A total three samples were collected for three times in three consecutive months of study period and analyzed by using standard analytical procedures.Geo spatial technology was adopted to represent the statistical data of water quality in the form of GIS maps for more accuracy to identify the periodical changes in water quality at study area

Wood fuel as a domestic combustible plays a major role for the Malian population (more than 90% of households depend on it for domestic cooking). It is used in rural as well as in urban areas. This paper focuses on assessing the energy source preference of households and stand diversity in Bamako catchment area. We have surveyed 200 households and 70 firewood and charcoal sellers in the District of Bamako. Forest inventory was carried out in Famana and Kassela within the Bamako catchment area where plots have been established (10 plots of 50 x 20 m per site). Plots were separated from each other by 50m. Results showed that the use of charcoal is higher than firewood in the urban households due to its availability and easy handling. 71.50% of households in Bamako use charcoal for cooking meals. Charcoal has become the most preferred source of energy for households in Bamako. The main factors for this trend are related to poverty, cooking habits of households, and urbanization. The two sites (Famana and Faya) are characterized by high diversity. Famana has a Shannon Diversity Index of 2.92 while Faya has 2.55. The study revealed a strong capacity of woody formations to provide species such as Combretum glutinosum, Combretum micranthum, and Lannea velutina which is very convenient for domestic combustion. These species have a rapid regeneration capacity and can grow in many types of ecological environments. Species such as Parkia biglobosa, Vittelaria paradoxa, Ficus gnaphalocarpa, and Khaya senegalensis (protected species) that are highly appreciated by households of Bamako have a great economic value and are constantly under threat. Households demand for these species exceeds the production capacity of forests. Immediate actions are needed to promote modern energy in order to ensure sustainable development.

The rapid spread of the new coronavirus across the world has raised concerns about the responsiveness of cities and healthcare systems during pandemics. Recent studies try to model how the number of COVID-19 infections will likely grow and impact the demand for hospitalization services at national and regional levels. However, less attention has been paid to the geographic access to COVID-19 healthcare services and to the response capacity of hospitals at the local level, particularly in urban areas in the Global South. This paper shows how transport accessibility analysis can provide actionable information to help improve healthcare coverage and responsiveness. It analyzes accessibility to COVID-19 healthcare at high spatial resolution in the 20 largest cities of Brazil. Using network-distance metrics, we estimate the vulnerable population living in areas with poor access to healthcare facilities that could either screen or hospitalize COVID-19 patients. We then use a new balanced floating catchment area (BFCA) indicator to estimate spatial, income and racial inequalities in access to hospitals with intensive care unit (ICU) beds and mechanical ventilators while taking into account congestion effects. Based on this analysis, we identify substantial social and spatial inequalities in access to health services during the pandemic. The availability of ICU equipment varies considerably between cities and it is substantially lower among black and poor communities. The study maps territorial inequalities in healthcare access and reflects on different policy lessons that can be learned for other countries based on the Brazilian case.

Runoff Quality

Diffuse pollution is a major source of contaminants to surface waters in urban areas. Land use activities and the degree of imperviousness have a strong influence on the pollutant loadings and the pattern and distribution of the pollutograph. Uncontrolled discharges of contaminated urban storm water runoff contribute to impairments of water quality in receiving waters. In this study, grab samples of storm water runoff were collected from a small high-density residential catchment area in Bucharest. The pollutant concentrations were analysed for several water quality physical and chemical parameters including pH, conductivity, oil and grease, nutrients, pathogen indicator bacteria and some heavy metals. The storm events were monitored through grab sampling. The sample results for this representative residential catchment area in Bucharest were then compared with data reported from other regions of the world. The analysis demonstrates that the characteristics of the urban runoff quality from residential areas in Bucharest were comparable with data obtained from other areas in the world.
