Abstract The majority of Australian adolescents are insufficiently active and becoming car dependent. Replacing short passive travel (i.e. car, public transport) with active travel could be an important potential strategy to increase physical activity. This paper aims to characterize adolescents’ travel patterns to various destinations, identify passive trips that could be feasibly replaced by active

Abstract E-commerce results in more last mile deliveries, increased freight traffic and potentially also higher CO2- emissions. This paper is a novel contribution to the literature in terms of investigating consumers’ willingness to pay (WTP) for climate-friendly last mile deliveries through reduced or no CO2-emissions from the delivery. 460 females between 18 and 70 years of age responded to an internet

Abstract This paper introduces a sub-leasing type of round-trip carsharing to enhance its efficiency for both customers and companies. This innovative type of carsharing provides new temporary stations and allows customers to access both vehicles in the company's stations and vehicles already reserved but parked and unused in other locations. The evaluation is performed using simulation with available

Abstract We investigated the asymmetric effects of energy consumption, car ownership and tourism activities on CO2 emissions in the UK. Empirical results from the Non-Linear Autoregressive Distributed Lag (NARDL) model reveal that in the UK, only car ownership has asymmetric effects on emissions with a magnitude of −1.428% (positive) and 10.108% (negative) shocks that highlight the impact of car ownership

Abstract Predicting the intention of mode choice is indispensable for policymakers to develop sustainable transportation in large cities. This paper constructs a conceptual framework and tests it in the travel mode sector to investigate the influence mechanism between commuter’s low-carbon literacy and intention of mode choice. Commuter’s low-carbon literacy (LCL) was assessed through four critical

Abstract The European transportation sector employs 10 million people and accounts for 4.6% of the European Union GDP. Due to climate change, this workforce is increasingly affected by high temperatures and radiant loads, particularly during summer. They rely on air conditioning (AC) to minimize heat inside the truck cabins, increasing fuel consumption and tailpipe emissions. Because sustainable transportation

Abstract With the accelerating pace of climate change, there has been no scarcity of research, in recent years, that assess climate risks and cost-effectiveness of adaptation measures in the transport sector. Nevertheless, existing literature associated with adaptation planning for climate change is still at an embryonic stage with little attention on certain potential dilemmas. Understanding such

Abstract This study explores gender differences in commute behavior with a focus on two-earner households using data from the 2001, 2009 and 2017 U.S. National Household Travel Surveys (NHTS). To understand whether gender differences are shrinking or persistent in terms of commute distances, we first analyze these differences by assessing descriptive statistics and t-test across multiple population

Abstract Greenhouse gases emissions modify the radiative balance of the Earth, causing changes in its climate. Climate Change is considered one of the greatest threats to economic and social stability. Aviation is responsible for around a 2.5% of greenhouse gases emissions. This contribution is steadily increasing, thus the interest of assessing the impacts that different policies might have on it

Abstract Freight transportation—specifically, fuel consumption during delivery operations—is one of the main contributors to global CO2 emissions. In this article, we study the effect of eco-driving practices (e.g., avoiding idling, keeping a steady speed) on fuel efficiency and CO2 emissions. We also explore the effect of a sustained intervention supporting eco-driving on the adoption of eco-driving

Abstract The significant positive and negatives effects of transportation systems (TSs) on the sustainability of cities and human life draw much attention from both researchers and managers. Constructing bus rapid transit (BRT) networks, or adding new lines to the existing ones, is one of the cheapest and easiest solutions to improve the performance of the urban transportation network (UTN). Often

Abstract Port activity brings economic benefits to port cities but also generates negative environmental externalities. These negative externalities derived from pollutants represent a social cost for port cities and coastal areas close to ports, and include costs derived from damages to urban buildings, damage to vegetation and damage to the health of the local population. This raises the question

Abstract Electric vehicles (EVs) attract increasing attention among consumers worldwide due to their innovative and environmentally-friendly properties. Buying an EV is not only an environmentally-friendly behavior but also an innovation-acceptance behavior. Accordingly, consumer propensities associated with environmental-innovative products—environmental propensity and innovative propensity—are expected

Abstract This paper proposes a general framework to explore the interaction between land use and transport systems. Hypotheses about those relationships are generated. A series of statistical tests are conducted to explain the co-development of land use and transit networks for metropolitan areas at a micro-geographic scale and to disentangle causes and effects. The specific case of Minneapolis - Saint

Abstract Despite their similarities, Scandinavian countries have adopted starkly different automobile tax regimes. The Danish system entails very high and convex tax rates with moderate CO2 differentiation. In Norway, tax rates are high and convex with strong CO2 differentiation and total exemptions for zero emission vehicles, even from value added tax. Sweden practices feebates – CO2 dependent subsidization

First, a multiregional hybrid life cycle sustainability assessment model is built to evaluate macro-level sustainability impacts of various

Abstract The supply of as well as the demand for carsharing has been increasing in recent years. Yet, these dynamics and carsharing's function as catalyzer toward a more sustainable transport behavior in German cities are still not fully understood. For this reason, we analyze supply data for 80 large cities in Germany regarding fleet numbers and supply densities. We combine this with analyses about

Abstract Since economic reforms in the late 1980s, Vietnam’s economy has grown rapidly, but transport activity has grown faster presenting a significant challenge for reducing transport related CO2 emissions. This paper explores this challenge by comprehensively evaluating decoupling in Vietnam’s transport sector over the period 1995 to 2017. Decoupling elasticities reveal that there is no decoupling

The survey questions were categorized into four latent variables through exploratory factor analysis and confirmatory factor analysis: road conditions

Abstract Staying within the 2 °C (preferably 1.5 °C) limit requires fast and fundamental system changes, also in urban passenger transport. Shifting car traffic to environmentally friendly transport modes is one central strategy to make urban transport more sustainable and climate friendly. However, in most cities car use remains high. Therefore, this paper analyzes what course change is needed regarding

Abstract Modern life requires increasingly complex and diverse travel behavior. We attend multiple destinations for multiple purposes, and trips are chained together as households negotiate the demands and opportunities presented by cities. To compete with the autonomy and flexibility of the private car, a successful public transport system should accommodate this complexity. Drawing from a series

Heavy vehicles are poised to potentially be one of the greatest beneficiaries due to their high operating costs. Here a facility location problem approach is adopted to analyze a sample of deidentified truck trip data, providing initial

Abstract A deep understanding of driver behavior is an important step to improve road safety and environmental performance. Volatility can be defined as the extent of variations in driving, which can be characterized by accelerations/braking, lane change, and unusual high speed for roadways conditions. There is a lack of knowledge on what concerns the relationship between driver’s volatility and exhaust

Abstract Cycling is a desirable mode of transportation in urban areas due to its environmental, social, and economic benefits. Design manuals are used as standardized references and guides to provide safe, functional, and convenient bicycle infrastructure. These guidelines usually provide best practice recommendations and refer to minimum requirements for dimensions (geometry) and materials. However

Abstract Despite a marked increase in electric bicycle (e-bike) research, few studies have looked at how parents or caretakers use e-bikes specifically to transport children. This is a missed opportunity, as parenthood often results in increased auto dependence. Getting more parents or caretakers on e-bikes or to continue biking would align with policies aimed at decreasing automobile dependence and

Abstract Annual emissions from commercial aviation are forecast to reach 1820 MtCO2 by mid-century, where carbon-neutral growth would demand near full substitution of petroleum-based aviation fuels with alternative jet fuels (AJF). However, the lack of dedicated policies and harmonized regulations has been perceived by stakeholders within the air transport community as the major contributor to shortfalls

Abstract The objective of this research was to map out the greenhouse gas (GHG) footprint of Ontario transit agencies. A system-by-system GHG emissions model was developed to determine which transit agencies are low, medium, or high emitters based on the metric tonnes of carbon dioxide equivalent (CO2e) emitted from mobile sources. A score card was created based on four preliminary indicators: (1)

Abstract Carsharing is becoming an important member of urban mobility systems. The relationship between carsharing and other travel modes, is the base for deciding the proportional role of carsharing. This article defines the relationship, competition or cooperation, based on whether carsharing strengthening or weakening the expected function of other travel modes from the transport system perspective

First of all, continuity of the confounders is assessed. Results indicate that all the confounders are continuous at the cutoff. Then, the impacts

Abstract Electric vehicles (EV) are widely seen as a sustainable alternative to gasoline vehicles to decrease emissions and dependence on fossil fuels. However, range anxiety, limited range, long charging time, and insufficient charging infrastructure have affected EVs’ adoption. High-end batteries and chargers can decrease the charging demand and charging time, respectively, and increase the EVs’

Abstract Car sharing represents a promising solution for sustainable transportation. Considering that there are already many cars that are not used to their full capacity, car sharing communities, whereby a group of people share access to a car, represent a sustainable alternative. However, sharing a car within a community results in the challenge of shared contributions and shared requests and thus

Abstract With the introduction of the carbon emission cost system initiated by the Carbon Offsetting and Reduction Scheme for International Aviation(CORSIA), the improvement of fuel efficiency in flight operations will have higher impact on airline profitability than before. In-flight fuel consumption is somewhat influenced by pilots’ technical actions when maneuvering aircraft during flight. This

Abstract Active mobility offers an array of physical, emotional, and social well-being benefits. However, with the proliferation of the sharing economy, new nonmotorized means of transport are entering the fold, complementing some existing mobility options while competing with others. The purpose of this research study is to investigate the adoption of three active travel modes—namely walking, cycling

Abstract Private Autonomous Vehicles (PAV) and Shared Autonomous Vehicles (SAV) are known to improve safety, mobility, roadway capacity, driver productivity and reduce parking costs (due to better utilization of space and self-parking to less expensive spots). However, the increased vehicle miles traveled (VMT), might increase overall emission production, system travel time, and operating costs. Also

Abstract This study empirically investigates the causes of urban traffic congestion to bring into focus the variety of beliefs that provide support for policy interventions to mitigate traffic congestion in USt cities. We use a structural equation modeling (SEM) framework and position the analysis at the meso-scale (i.e., neighborhood shapes, sizes, density, land-use mix, street design, distribution

  The transport sector needs to become sustainable and public transport has an important role to play. Green public procurement has proven to have great potential to influence the transition to a sustainable public transport sector. Sweden is a good example of a country that uses public procurement in the public transport sector to a large extent and has at the same time come far in the transition

Abstract The increasingly widespread use of vehicles has intensified fuel consumption and hence the emission of air pollutants, causing a negative environmental impact on both human health and climate change. It is well known that vehicle fuel consumption depends on several factors such as engine and vehicle technology, road characteristics, traffic conditions, and driver ability. Although the relationship

Abstract Street attributes are thought to play an important role in influencing pedestrian route choices. Faced with alternatives, pedestrians have been observed to choose faster, safer, more comfortable, more interesting, or more beautiful routes. Literature on pedestrian route choice has provided methods for assessing the likelihood of such options using discrete choice models. However, route choice

Abstract A higher Body Mass Index (BMI) is often associated with higher risks for health-related issues (e.g., arthritis, cancer). Lifestyle behaviors (e.g., healthy diet) are believed to be important factors closely related to people’s BMI and health. Among the behaviors, active travel modes (e.g., walking and bicycling) may be an important factor correlated with BMI. Such travel behaviors can somehow

Abstract The improvement of pedestrian mobility through the use of on-street vertical facilities, i.e. escalators, moving sidewalks, lifts, funiculars and gondola lifts, is becoming increasingly important in many cities with steep slopes that hinder walkers’ transit. However, studies on the acceptance, profitability and demand for these facilities are still scarce. The present paper proposes an assessment

Abstract Mobility in metropolitan rings is often more car-dependent than in urban cores. Buses are emerging as an efficient option to promote sustainable mobility in metropolitan corridors, although they are perceived as being less reliable than rail or the car. The adoption of real-time information (RTI) tools for passengers can mitigate this issue. This paper aims (i) to explore the potential bus

Abstract The most important reason for the rapid increase of global warming and the occurrence of related climate changes is the contamination caused by greenhouse gases released into the air. Whereas air pollution affects human health significantly, it also threatens the lives of plants and animals. As it is known, the majority of the human population contemporarily lives in cities. In these circumstances
