Water Supply And Sanitation

The sanitary problems promoted by the rapid urbanization process in developing cities are usually resulted from the absence of planning, high population concentration and inadequate water and wastewater infrastructure for low income people. Because the provision and planning of water supply and is a complex task, a modeling approach was used to enhance the understanding of the process and the aspects involved. In the development of a model, not only the technical aspects were taken into account, but other aspects related to the provision of drinking water and the water resources protection were also analyzed, such as institutional, financial, socioeconomic, environmental and public health. In the modeling process two different methods of conceptualization were used to describe the urban water flow through the water and wastewater systems linked to various aspects related to their implementation in large developing cities. The urban water systems of five large metropolitan areas in Brazil were also evaluated for the complete model. It is expected that the modeling approach developed in this paper consists of a valuable methodology for water supply and sanitation planning in Brazilian cities, and other developing cities with the same characteristics. The suggested conceptual model could, at least, provide more than a starting point for a useful urban water management tool.

In this work, we present a novel approach to understand the quality of public transit system in resource constrained regions using user-generated contents. With growing urban population, it is getting difficult to manage travel demand in an effective way. This problem is more prevalent in developing cities due to lack of budget and proper surveillance system. Due to resource constraints, developing cities have limited infrastructure to monitor transport services. To improve the quality and patronage of public transit system, authorities often use manual travel surveys. But manual surveys often suffer from quality issues. For example, respondents may not provide all the detailed travel information in a manual travel survey. The survey may have sampling bias. Due to close-ended design (specific questions in the questionnaire), lots of relevant information may not be captured in a manual survey process. To address these issues, we investigated if user-generated contents, for example, Twitter data, can be used to understand service quality in Greater Mumbai in India, which can complement existing manual survey process. To do this, we assumed that, if a tweet is relevant to public transport system and contains negative sentiment, then that tweet expresses user’s dissatisfaction towards the public transport service. Since most of the tweets do not have any explicit geolocation, we also presented a model that does not only extract users’ dissatisfaction towards public transit system but also retrieves the spatial context of dissatisfaction and the potential causes that affect the service quality. It is observed that a Random Forest-based model outperforms other machine learning models, while yielding 0.97 precision and 0.88 F1-score.

In many developing cities, the improvement of transport infrastructure is usually accompanied by major road construction and maintenance. This paper presents approaches and opportunities using peer-to-peer updating to improve spatial road networks undergoing construction and maintenance, which in turn will improve traffic flow and benefit cities overall. In many cities, the spatial road network requires maintenance, and these works often require traffic detours. With the current GPS (Global Positioning System) services, there is a noticeable delay in the updating of many spatial road networks. Thus, when a driver plans a trip to a certain location (such as Starbucks), his/her usual route may have changed, but the spatial road network in the GPS has not been updated. This can affect the user in many ways. For example, a trip that usually takes five minutes might now take half an hour, taking into account the additional time required to find alternative roads and possibly encountering more unexpected road closures, until the driver reaches his/her destination. This paper addresses this issue by proposing solutions that offer several advantages including a new peer-to-peer updating mechanism that helps to direct the driver to another route when road changes occur. Moreover, the peer-to-peer updating mechanism can enable the independent monitoring of road conditions and the updating of maps for newly-constructed roads, as well as the analysis of road congestions, traffic density, and people movements at certain times. Note that this work focuses on the conceptual ideas and approaches intended to improve independent maps, and the detailed algorithms have been left for future work.

Two Phases

The need for a mid-tier transit system and the opportunities created by 21st century transit technologies like Trackless Trams System (TTS) has been analysed in an earlier paper to show TTS could be a leapfrog solution for the future of sustainable urban development in developing cities. This paper outlines how the TTS can be created as a part of Transit Oriented Development (TOD). Informed by literature, this study identified four factors that are important for enabling transition towards TOD. Using three of these factors a framework for assessing and evaluating TOD is formulated. The study then applies the formulated framework to the potential corridors that could potentially enable a transition towards a successful TOD for Bulawayo and enable the TTS to be delivered in a partnership with urban land development. The findings do reveal that most of the station precincts that are closer to the CBD have a higher potential to enable transition to TOD. This could suggest that the TTS could be implemented in two phases, the first phase covering the high impact station precincts.

Public Costs

Public transport is recognized as a more environmentally friendly mode of transport than cars for the same number of passengers. Many countries are investing heavily in public transport to make it not only greener, but also more convenient, more attractive, faster, more competitive and more accessible. In order to promote a sustainable environment, private, public and non-motorized transport must functionally complement each other to form balanced integrated systems. There are currently two main forms of organizing public transport: a government-oriented service and a market-oriented service. Positive changes in the field of public transport are possible if in the process involves not only state and municipal institutions, but also infrastructure planners, passenger carriers and inhabitants. Public transport must be seen as a means of developing cities and regions. The aim of the article is to analyze the existing models of public transport organization and management, to compare them and submit a proposal, on the basis of which management model it would be possible to submit proposals for the improvement of the organization of Lithuanian public transport. Good foreign countries practice in the management and organization of public transport shows that in some countries public transport is already organized not by individual municipalities but by regions. Based on the achievements of foreign countries, municipalities are recommended to cooperate and share experience in creating a common public transport network. It is necessary to create a management scheme in Lithuania for the development of public transport services, which at the same time would reduce public costs.

The subject of this research is the problem of preservation of historical heritage aggravated to rapid urbanization, which is characteristic to many developing cities. Special attention is given to the existing trends of total destruction of historical and cultural monuments in the conditions of dense urban fabric. The relevance is defined by the dynamically increasing process of degradation, and at times, full destruction of environmental objects that are listed as state protected. The theoretical framework of this research is comprised of the system-environmental approach, which views the urban environment surrounding the landmarked object as a system that is in direct interaction with it. The novelty consists in practical application of theoretical provisions of the system-environmental approach to the specific conditions of Khabarovsk. Having explored over two dozen of landmarked buildings of the city, the authors reveal the contradiction between legislation intended for legal regulation of the protection and use of architectural heritage and the actual city practice of exploitation of historical buildings by the new owners of the landmarks. The study was conducted in cooperation and on behalf of Khabarovsk Regional Center for the Protection of Historical and Cultural Monuments. The results are used in practical activity of the center and in development of its strategic goals.
