Structured Questionnaire

The main objective of present study is to evaluate private vehicle commuters’ knowledge and concern about health and environmental impact of transportation related air pollution in Klang Valley, Malaysia. Data were collected using structured questionnaire and interviewing 450 car commuters in five main areas of Klang Valley. The Results indicated that majority of respondents (58%) have knowledge about deteriorating effect of transport on society’s health and welfare. While, only 36% of them were concern about the transport related environmental problems. This study suggest that government intervention through increasing toll, parking fee and introducing congestion fee together with providing more efficient public transport can reduce more than half of travels by car.

Malaysia governments are seeing that the future of transportation to be creating an environmentally clean and sustainable for the benefit of the people.A huge amount of investment has been made by the governments towards a public transportation sector by expecting that the infrastructure and sustainability of transportation could change the number of modal share gradually. However, the numbers of modal share has not increased compared to private vehicle usage of Kuala Lumpur, Malaysia. Therefore, a study on the travellers (both public and private vehicle users) attitudes is important to help understand the similarity or differences that could explain the modal share. The purpose of this study is to compare the attitudes of travellers in the Kuala Lumpur city centre by analysing the similarities and differences of attitudes among Public Transport users (PT) and Private Transport users (PV). The attitude being studied is about travelling without any specification of modes, thus examining 1790 KL dwellers objectives and provide the basis for fair and just comparison with regard to PT and PV. The attitudes towards travelling were measured by a 5-point Likert scale using a structured questionnaire, and statistically analysed by applying factor analysis provided in SPSS. The study found that six attitudes define the attitudes of PT traveller towards travelling, and three attitudes were influencing PV travellers toward travelling. Based on this outcome, the key attitudes that influence travellers’ willingness to use public transport were discussed and identified. The results lead to understanding the attitudes of people towards travelling from the eye of public transport and private transport users. The understanding forms concrete basis for government to plan on strategies to shift private vehicle users and promote usage of public transport. For operators, the understanding also provides invaluable input for strategic planning of marketing effort/public policy.Keyword-TravellerAttitude,Age,Gender,Incomelevel,PublicVehicle,PrivateVehicle

The paper intends to assess the impact of the odd–even scheme on the travel pattern of the daily commuters in Delhi. The objective of the paper is to assess the impact of the odd–even scheme on mode choice for daily work trips, shift in travel patterns – before, during, and post-implementation – of the odd–even scheme, and to understand people perception regarding the odd–even scheme. Based on the primary survey, the paper concludes that the odd–even scheme brought a significant impact in the travel pattern in terms of occupancy, travel cost, travel time, and modal shift, and statistically not so much on the air quality gain. It was observed that the scheme helped increase the occupancy rate in cars as well as ridership of buses and Delhi metro. The scheme had a huge impact on congestion, which was evident from both perception analysis and the change in travel time. The modal shift, with an improvement in public transport services and a reduction in car users, is one of the key successes of the scheme resulting in decrease in air pollution caused by private vehicles. To improve the outcome of the odd–even scheme on air pollution, two-wheelers should not be exempted going forward.

Developments in the field of automated mobility will greatly change our mobility and the possibilities to get from one place to another. This paper presents different scenarios for personal mobility in Austria, anticipating the possibilities and developments in the field of automated vehicles (AVs). The scenarios were developed using a systematically formalized scenario technique and expand the social and political discourse on automated mobility, which is currently characterized by a lack of experience and visibility as an established transport service. Using system dynamics modeling techniques, i.e., the Metropolitan Activity Relocation Simulator (MARS), impacts of the scenarios on the Austrian transportation system are estimated. The simulations show that, without suitable transport policy measures, automated mobility will lead to a significant increase in the volume of individual traffic and to modal shift effects with lower traffic volumes for public transport, walking and cycling. In addition, without a link between AVs and post-fossil propulsion systems, increases in pollutant emissions can also be expected. In contrast, the simulation results of an increased use of AVs in public transport show positive effects for the support of a more sustainable mobility. Hence, transport policy measures accompanying the introduction and development of automated vehicles will be needed in the future to reach a sustainable development.

<p>Car use is engrained in our culture. Changing behaviour towards using more sustainable travel modes such as public transport is notoriously difficult, despite the increasing awareness of environmental problems caused by car use. Integrated ticketing is a policy measure more recently used in strategies towards achieving integrated and sustainable transport systems. It allows a passenger to travel with one public transport ticket throughout a region. This research uses a mixed method approach to assess how integrated ticketing may affect public transport use in Greater Wellington. The psychological constructs determining decisions to use public transport are tested using an integrated environmental behaviour model proposed by Bamberg and Möser (2007). The results support the integrated modelling approach. Intentions to use public transport are indirectly affected by awareness of environmental problems caused by car use mediated through social norms, guilt, perceived behavioural control and attitude. The intention to use public transport explains 56% of the variance in public transport behaviour. Integrated ticketing presents an opportunity to increase the ease and convenience of travel, shown to be important in the model. The majority of survey respondents perceived that they would use integrated ticketing in Greater Wellington and that it was important both on a regional and national scale. Achieving an effective integrated ticketing system in Greater Wellington will be conditional on firstly improving public transport service reliability and stakeholder communication. Integrating fares across the region and across modes will also be crucial to the success of the system.</p>

The environmental problems accompanying concrete come from cement. This means that the final product i.e., concrete is an environmentally sociable material by itself. This guides us to play on the concrete constituents which cause the largest environmental impact, which is cement. Therefore, if we can abate cement amount and increase cementing materials which can substitute cement for concrete, we will be able to minimize the concrete impact on the environment. The saving of cement quantity in concrete can be realized by substituting it with diverse extra cementitious materials which are a by-product of another industry and waste of agriculture.

This study assesses changes in mobility behaviour in the City of Barcelona due the COVID‐19pandemic and its impact on air pollution and GHG emissions. Urban transport is an important sourceof global greenhouse gas (GHG) emissions. Improving urban mobility patterns is therefore crucial formitigating climate change. This study combines quantitative survey data and official governmentdata with in‐depth interviews with public administration officials of the City. Data illustrates thatBarcelona has experienced an unprecedented reduction in mobility during the lockdown (a 90%drop) and mobility remained at comparatively low levels throughout the year 2020. Most remarkableis the decrease in the use of public transport in 2020 compared to pre‐pandemic levels, whereas roadtraffic has decreased to a lesser extent and cycling surged at times to levels up to 60% higher thanpre‐pandemic levels. These changes in mobility have led to a radical and historic reduction in airpollution, with NO2 and PM10 concentration complying with WHO guidelines in 2020. Reductions inGHG emissions for Barcelona’s transport sector are estimated at almost 250.000 t CO2eq in 2020 (7%of the City’s overall annual emissions). The study derives policy implications aimed at achieving along‐term shift towards climate‐friendlier, low‐emission transport in Barcelona, namely how torecover lost demand in public transport and seize the opportunity that the crisis brings for reform byfurther reducing road traffic and establishing a 'cycling culture' in Barcelona, as already achieved inother European cities.

The concept of circular economy supports mitigation of climate change and other environmental pressures to the planet. Circulating materials in anthropogenic processes come with the risk of accumulating hazardous substances and compounds. In this concept, waste incineration or waste-to-energy (WtE) is a necessary technology to remove these compounds from the life cycle. In this mini-review, contaminants of major importance in the flue gas from waste incineration plants and their environmental impact are discussed. Air pollution of WtE is often seen as the most relevant environmental impact of this treatment option. The emission values parameter set for different countries is presented and compared. The most stringent legally set of emission values could be found in parts of Europe and South Korea. Japan also permits similar strict values when authorising individual incineration plants. In North America, the values are partially less strict as the best available technologies in Europe suggest being possible. Emerging economies, such as India and China, have shown efforts to improve their environmental protection standards but still have room to improve. This could be set in relation to other industrial emitting processes and therefore could be used to assess the relevance of this industry sector to the national emission inventories.
