Available in PDF, EPUB and Kindle. Book excerpt: This Brief examines the impact of the Oxford Transport Strategy in central Oxford as a means of assessing the effect of reduced traffic congestion in the city centre on its sustainability. Air pollution (from vehicular traffic) has been monitored at three locations in central Oxford on the High Street, St Aldates and St Ebbes (background monitoring station). There is a further monitoring site situated in East Oxford, but this one is not considered to be central. Based on long-term monitoring at these monitoring stations, a deliberation of urban sustainability is presented. Implications are considered for long-term planning and green design in particular is part of the discussion. More specifically, urban greening strategies are presented as (soft engineering) approaches to controlling air pollution problems at this urban location. In the context of low carbon cities, green walls are assessed as they affect urban greening and energy conservation, as they enhance insulation on the exterior of solid wall buildings. Urban sustainability is best monitored using decades of data rather than just years. The Oxford Transport Strategy (OTS) was implemented in central Oxford, UK in 2001 and now a record of at least a decade of monitoring data is available for such a longer-term assessment. This work revisits the OTS from long after its implementation in the Oxford city centre and specifically examines the impact of reduced traffic congestion on sustainability. This includes address of traffic congestion, air pollution (from vehicular or traffic pollution) and the effects on the urban environment, including buildings. In parallel to this, the role of urban vegetation is considered as a sink for a variety of pollutants. Green walls, as part of urban greening, have implications for low carbon cities in the context of urban heat islands and global warming.

Available in PDF, EPUB and Kindle. Book excerpt: This book brings together the methods, models and formulae used for estimating air pollution concentrations in urban areas. From the ForewordThe visible effects of pollution in most cities in the developed countries have been reduced dramatically in the past thirty years. This has been achieved to a large extent by the replacement of most of the low-level sources, which burnt raw coal, by more modern appliances using gas, electricity or low-sulphur oil. The killer smog of 1952 could not be repeated unless there were to be a massive return to old-fashioned heating methods, due, for example, to excessive environmental constraints being applied to the more modern energy sources. It is important, therefore, to judge the impact of a new source in terms of its effect on the pattern of existing sources. One should also consider the environmental consequences of rejecting the new installation and examine the alternatives--that its product may either be denied to the community at large, produced elsewhere or produced using existing facilities. These facilities are probably less efficient and may therefore produce more pollution per unit of product than the new plant would. An objective, quantitative, urban-air-pollution model is clearly an essential component in such a decision-making process. Dr. Benarie has produced a distillation of existing modelling techniques which will, I hope, become the launching pad for many future models. As each city is unique, it will need its own tailor-made model, drawing on the best and the most appropriate techniques developed previously. Agreement with observations is the only real test of validity, because the physics and chemistry are so complicated that theoretical arguments are reduced to the role of assisting in the best formulation of the problem. Numerical precision must always rely on measurement. This is the approach that Dr. Benarie has adopted.--David J. Moore, Central Electricity Research Laboratires, Leatherhead, Surrey, UK.

This book was released on 2011-05 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the many processes that influence ground level concentrations of greenhouse gases and air quality pollutants is crucial to interpreting the impact of anthropogenic atmospheric emissions. In particular, characterising the role of the road transport sector as a major emission source enables improved assessment of the available abatement opportunities. The present study utilises both atmospheric modelling and monitoring to evaluate the current variation in carbon dioxide and nitrogen oxides across London and the wider UK. The potential benefits of future road transport scenarios are assessed through an Integrated Assessment Model. The analysis should be of interest to professionals concerned with the climate change and air quality benefits of adopting hybrid buses and fully electric vehicles in urban areas.

Download or read book Traffic Emission Modelling for Robust Policy Design in Connected and Electric Transportation written by Ran Tu and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traffic emissions such as greenhouse gases (GHGs, in CO2eq), nitrogen oxides (NOx), and traffic-related air pollution lead to global problems including climate change and public health issues. In order to mitigate the impacts of growing urban traffic on emissions and air pollution, travel demand management, driving operation control, and advanced technology initiatives have been implemented in many cities. The aim of this research is to realize robust transportation policy decisions with improved emission estimation approaches at local and regional levels. In the first module of the thesis, the emission factor (EF, in grams of traffic emissions per unit distance) within one traffic condition, which is commonly defined as a single value, is expanded to a distribution. A regional emission distribution is therefore established using the EF distribution, enhancing the robustness of policy analysis. Meanwhile, the identification of the EF variation leads to the development of a machine-learning based emission estimation approach, CLustEr-based Validated Emission Re-calculation (CLEVER). The CLEVER approach can accurately estimate regional traffic emissions without heavy data collection burden through refined traffic condition categories and representative EFs using traffic data of multiple resolutions. In the second module, several traffic emission control strategies are tested from perspectives of emissions, air pollution, and energy consumption. First, a travel demand management targeting on high-emitting trips is tested. Compared to a short-distance trip management, the proposed strategy is more effective on reducing GHG emissions and improving traffic conditions. Second, a travel-time minimized routing algorithm with connected automated vehicles is applied in an urban road network and the application causes potential increases of near-road NO2 concentrations. Lastly, electric vehicle charging schedules are optimized to minimize GHG emissions from electricity generation. The optimized plan demonstrates high potentials for reducing GHG emissions. However, trade-offs between emission reductions and charging facility costs are identified by comparing the optimized plan with non-optimized plans. This research achieves a reliable regional traffic emission estimation with much less data requirement. Based on that, innovative control strategies proposed in this research and their comprehensive evaluation process can contribute to a robust transportation policy decision.
Download or read book An Integrated Multi model Approach for Predicting the Impact of Household Travel on Urban Air Quality and Simulating Population Exposure written by Marianne Hatzopoulou and published by . This book was released on 2008 with total page 718 pages. Available in PDF, EPUB and Kindle. Book excerpt: The population and economic growth experienced by Canadian metropolitan areas in the past twenty years, has been associated with increased levels of car ownership and vehicle kilometres travelled leading to a deterioration of air quality and public health and an increase in greenhouse gas emissions. The need to modify urban growth patterns has motivated planning agencies in Canada to develop a broad range of policies aiming at achieving a more sustainable transportation sector. The challenge however, remains in the ability to test the effectiveness of proposed policy measures. This situation has led to a renewed interest in integrated land-use and transport models to support transport policy appraisal. This research is motivated by the need to improve transport policy appraisal through the use of integrated land-use and transport models linked with a range of sub-models that can reflect transport externalities. This research starts with an exploration of the transport policy environment in Canada through a questionnaire-based survey conducted with planners and policy-makers. The survey results highlight the need for tools reflecting the sustainability impacts of proposed policies. While the second part of this research explores sustainability indicators and recommends a set of social, economic, and environmental measures, linked with integrated land-use and transport models; effort is dedicated to estimate the environmental indicators as part of this thesis. As such, the third part of this research involves the development of an emission-dispersion-exposure modelling framework. The framework includes a suite of sub-models including an activity-based travel demand model (TASHA), an emission factor model (Mobile6.2C), a meteorological model (CALMET), and a dispersion model (CALPUFF). The framework is used to estimate link-based emissions of light-duty vehicles in the Greater Toronto Area under a base scenario for 2001. Dispersion of emissions is then conducted and linked with population in order to estimate exposure to air pollution.
