Abstract This global study simultaneously analyzes how land use differences between cities affect travel time and CO2 emissions. The land use–travel time–carbon emission relationship in which the time is specified as a mediator is analyzed at the city level on an international scale based on individually reported data by moving away from the tendency of conducting country-level, regional-scale analysis

Abstract This study develops a methodology to determine the optimal allocation position to deploy the bikes in a competitive dockless bike sharing market. The community structure approach in complex network theory is utilized to offer the bike allocation strategies to the market leader in two specific market regimes, with a potential competitor, and without a potential competitor. Two different heuristics

Abstract Monitoring pedestrian activities and understanding influential factors such as weather conditions and special events are important issues for urban planners who endeavor to foster a vital and sustainable urban environment. This study quantified pedestrian activity by developing pedestrian distribution indexes (PDIs) for the aspects of volume, space, and time, to clarify how PDIs were affected

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

Abstract The relationship between ambient conditions and light-duty vehicle energy consumption has been widely researched. Relatively little effort, however, has been dedicated to understanding representative ambient conditions a light-duty vehicle may experience. The framework introduced in this article provides a means of quantifying ambient conditions specific to light-duty vehicle operation by

Abstract The rapidly-increasing urban transportation contributes to a number of externalities such as congestion and pollution; moreover, environmental uncertainties widely exist and bring challenges to creating traffic emission control strategies. To address these problems, this paper proposes an inexact bilevel programming approach under stochastic and fuzzy uncertainties (BLP-SF) for a toll scheme

Abstract Plug-in hybrid electric vehicles (PHEVs) are an effective vehicle technology to reduce light duty vehicle greenhouse gas emissions and gasoline consumption. They combine all-electric driving capabilities of a battery electric vehicle with the engine downsizing and fuel economy improvements of a hybrid electric vehicle. Their environmental performance is predicated upon the metric utility factor

Abstract Shared e-mobility is a category of emerging mobility services that includes electric carsharing, e-bike sharing, and e-scooter sharing. These services are expected to reduce the negative externalities of road transport in cities, which is currently dominated by fossil-fuel-powered private car trips. In order to better inform the development and promotion of these services and indicate directions

Abstract A major challenge for humankind is to reduce global carbon dioxide (CO2) emissions to avoid the most harmful impacts of climate change. The transport sector is responsible for almost 1/4 of the world’s energy-related emissions, with road transportation representing around 1/5 of the fuel consumption. Electric vehicles (EVs) may help to reduce CO2 emissions, but their diffusion is uncertain
