Latin American busways: Moving people not cars

The rapid growth of Latin America urban centres beginning in the 1970s placed a heavy strain upon urban transport service providers. Facing high population growth from a citizenry dependent upon public transport and having limited financial resources to develop car-based infrastructure, Latin American municipal planners were challenged to create a new transport paradigm. One ingenious response to this dilemma was the busway, a surface metro system that utilizes exclusive right-of-way bus lanes. The developers of the Latin American busways astutely observed that the ultimate objective was to swiftly, efficiently, and cost-effectively move people rather than cars. Examples of innovative busway systems are presented from Curitiba, Bogota, Porto Alegre, Quito, and Sao Paulo. The low cost, flexibility, and speed of the exclusive busways all contribute to extremely high levels of customer satisfaction. Innovative approaches to the design of busway loading stations and simplified ticketing have also helped to reduce operating costs and improve customer flows. Additionally, clear system maps, colour-coded routing, system safety and cleanliness, and superior customer service have helped direct consumer preference towards the busway. The success of busways has also proved that costly subway systems or uncontrolled sprawl are not the only options available to municipal planners. The Latin American busway corridors provide high peak capacities that permit busway corridors to serve the transit requirements of most medium to large-sized cities. When integrated with progressive land-use policies, busways can also form the basis of more sustainable urban design by encouraging development corridors with high-density, mixed-use land use. The environmental benefits and calming influences afforded cities by busway systems have translated into dramatically improved levels of quality of life indicators, including improvements in health, crime reduction, and poverty alleviation. The user-friendliness and cost-effectiveness of busway systems have convinced municipal leaders in North America, Europe, and Australia to develop similar systems of their own. Latin American busways thus provide a unique example of South to North technology transfer

Pedestrian demand modelling of large cities: an applied example from London

This paper introduces a methodology for the development of city wide pedestrian demand models and shows its application to London. The approach used for modelling is Multiple Regression Analysis of independent variables against the dependent variable of observed pedestrian flows. The test samples were from manual observation studies of average total pedestrian flow per hour on 237 sample sites. The model will provide predicted flow values for all 7,526 street segments in the 25 square kilometres of Central London. It has been independently validated by Transport for London and is being tested against further observation data. The longer term aim is to extend the model to the entire greater London area and to incorporate additional policy levers for use as a transport planning and evaluation tool

A review on available energy saving strategies for heating, ventilation and air conditioning in underground metro stations

Due to the increasing number of underground metro stations worldwide and the great energy consumption of heating, ventilation and air conditioning (HVAC) systems in underground stations, reducing the HVAC energy consumption while maintaining a hygienic and acceptable environment in underground stations is becoming an ongoing research challenge. This paper presented an overview of the strategies available for HVAC energy saving in underground stations. Firstly, the design features of the HVAC systems are summarized and issues affecting the HVAC systems’ energy efficiency are identified. Then, a thorough review of the energy-efficient HVAC strategies is presented. For each strategy, the principal application and the effect on energy saving are described, and the limitation is also analyzed. Lastly, the strategies are classified and compared from different perspectives and upcoming challenges are proposed. The authors hope that this study can promote the reasonable adoption of different energy-efficient HVAC strategies in underground stations, which could reduce the energy consumption of the HVAC systems in the long run

Mass transit options

Choices on public transit options are choices about a city's future. Will there be congestion? Will there be high levels of air and noise pollution? Will transport be affordable? Will services be available to all? The type of public transit system will have a big impact on the answers to these questions. This module aims to provide policy-makers in developing cities - and those advising them - with guidance on choosing appropriate Mass Rapid Transit (MRT) systems. The module begins by briefly describing some basic concepts and defining features of MRT in developing cities. Current applications of each of the main MRT options are then described, focusing on applications in developing cities. Since Metros and Light Rail Transit are still relatively uncommon in low income developing cities, most of this discussion focuses on the recent development of Bus Rapid Transit systems throughout the world

Automated Transit Networks (ATN): A Review of the State of the Industry and Prospects for the Future, MTI Report 12-31

The concept of Automated Transit Networks (ATN) - in which fully automated vehicles on exclusive, grade-separated guideways provide on-demand, primarily non-stop, origin-to-destination service over an area network – has been around since the 1950s. However, only a few systems are in current operation around the world. ATN does not appear “on the radar” of urban planners, transit professionals, or policy makers when it comes to designing solutions for current transit problems in urban areas. This study explains ATN technology, setting it in the larger context of Automated Guideway Transit (AGT); looks at the current status of ATN suppliers, the status of the ATN industry, and the prospects of a U.S.-based ATN industry; summarizes and organizes proceedings from the seven Podcar City conferences that have been held since 2006; documents the U.S./Sweden Memorandum of Understanding on Sustainable Transport; discusses how ATN could expand the coverage of existing transit systems; explains the opportunities and challenges in planning and funding ATN systems and approaches for procuring ATN systems; and concludes with a summary of the existing challenges and opportunities for ATN technology. The study is intended to be an informative tool for planners, urban designers, and those involved in public policy, especially for urban transit, to provide a reference for history and background on ATN, and to use for policy development and research

Bus rapid transit

Effective public transit is central to development. For the vast majority of developing city residents, public transit is the only practical means to access employment, education, and public services, especially when such services are beyond the viable distance of walking or cycling. Unfortunately, the current state of public transit services in developing cities often does little to serve the actual mobility needs of the population. Bus services are too often unreliable, inconvenient and dangerous. In response, transport planners and public officials have sometimes turned to extremely costly mass transit alternatives such as rail-based metros. Due to the high costs of rail infrastructure, cities can only construct such systems over a few kilometres in a few limited corridors. The result is a system that does not meet the broader transport needs of the population. Nevertheless, the municipality ends up with a long-term debt that can affect investment in more pressing areas such as health, education, water, and sanitation. However, there is an alternative between poor public transit service and high municipal debt. Bus Rapid Transit (BRT) can provide high-quality, metro-like transit service at a fraction of the cost of other options. This document provides municipal officials, non-governmental organizations, consultants, and others with an introduction to the concept of BRT as well as a step-by-step process for successfully planning a BRT system

Smart Computing and Sensing Technologies for Animal Welfare: A Systematic Review

Animals play a profoundly important and intricate role in our lives today. Dogs have been human companions for thousands of years, but they now work closely with us to assist the disabled, and in combat and search and rescue situations. Farm animals are a critical part of the global food supply chain, and there is increasing consumer interest in organically fed and humanely raised livestock, and how it impacts our health and environmental footprint. Wild animals are threatened with extinction by human induced factors, and shrinking and compromised habitat. This review sets the goal to systematically survey the existing literature in smart computing and sensing technologies for domestic, farm and wild animal welfare. We use the notion of \emph{animal welfare} in broad terms, to review the technologies for assessing whether animals are healthy, free of pain and suffering, and also positively stimulated in their environment. Also the notion of \emph{smart computing and sensing} is used in broad terms, to refer to computing and sensing systems that are not isolated but interconnected with communication networks, and capable of remote data collection, processing, exchange and analysis. We review smart technologies for domestic animals, indoor and outdoor animal farming, as well as animals in the wild and zoos. The findings of this review are expected to motivate future research and contribute to data, information and communication management as well as policy for animal welfare

Water infrastructure and social housing in Bogotá: an intersection between modern water management and social housing production

En la actualidad Bogotá afronta la presión de construir viviendas sociales en ecosistemas frágiles, áreas rurales o zonas propensas a las inundaciones, y al mismo tiempo proteger estas áreas para asegurar la capacidad de resiliencia del medio ambiente. Ante esta contradicción, la pregunta de investigación es: ¿Cómo se pueden modificar las tendencias de urbanización para crear una interacción que favorezca el manejo sustentable del agua? Con el fin de responder esta pregunta ésta comunicación presenta un análisis histórico de planes de alcantarillado y control hidráulico desarrollados desde 1990, junto con una revisión de proyectos de vivienda social representativos, e investiga la interacción entre estos dos campos. El análisis permite definir diferentes etapas en la transformación física del sistema hídrico que se basan en los cambios universales de paradigma en la gestión del agua e ilustra diferentes construcciones socio-culturales en torno a la naturaleza, además analiza la producción de vivienda en relación a la transformación del sistema hídrico.Currently, Bogotá faces the pressure to continue to urbanize fragile ecosystems, rural lands and flood prone areas with low-cost housing projects and simultaneously protect these areas to ensure environmental resilience. Given this contradiction, the question is how urbanization trends could be reversed into a constructive interplay with a revised water management? In order to that, this paper provides an historical analysis of representative water infrastructure projects, urban plans and housing projects in Bogotá developed after 1900 and investigates the interplays between this two realms. The analysis allows to define different stages in the physical transformation of the water system that are based on universal paradigm shifts in water management and illustrates different socio-cultural constructions around nature. It also analysis the production of social housing in relation to the water system transformation

Adaptation of Urban High-density Neighbourhoods in Nodes of Sustainable Intelligent Mobility Condensers

In Europe and since the early twentieth century, municipal mobility policies have provided underground parking and public transport to many of the rapidly built social neighbourhoods between 1960 and 1980, which were planned lacking them. However, the climatic emergency requires new approaches that reduce CO2 emissions. This paper sets out the steps for the implementation of an Intelligent Mobility Condenser (IMC) in an existing neighbourhood. IMCs combine connectivity to public transport, together with the creation of a transport cooperative that meets the mobility needs of its neighbours without the need to own a private car. Similar to car-sharing, the IMC offers hybrid, electric, solar cars, along with motorcycles and electric bicycles. This together with a digital platform that facilitates the management of their needs. On the other hand, IMCs are automatic surface parkings, with solar collection and urban gardens, which, being high-access nodes in the neighbourhood, allow the incorporation of community, social and commercial spaces. The paper discusses the results based on the economic and environmental benefits of the model, and the threats of its implementation due to the difficulties of giving up the private car.Universidad de Málaga.
