Shipping activities emit pollutants such as NOX, SOX, and PM, which are detrimental to air quality and to the health of local residents. As one of the major shipping nations, China's population and port-related industries concentrate in coastal areas. However, an interesting phenomenon is that the average life expectancy of coastal port cities in China has not significantly decreased in the past few

Developing safe and efficient cycling networks is a vital part of creating more bike-friendly and, thus, more sustainable communities. To promote cycling effectively, continuously improving and expanding the cycling network is important. Yet, understanding and measuring the impact of newly developed cycling infrastructure is not always a straightforward task, which is often performed using limited-scope

The predominant mode of public transport in South Africa originates from the informal sector, specifically “paratransit”. Vehicles carry up to 23 passengers and are still propelled by internal combustion engines. We investigate the feasibility of using electric vehicles without negating the loss of opportunities by drivers and owners. We propose that scheduling of the electric vehicles is one important

Accessibility, the ease of interacting with potential opportunities, is an increasingly important tool among transport planners aiming to foster equitable and sustainable cities. However, in accessibility research there is a historical focus on employment destinations that is shaped by a masculinist transportation planning tradition. This paper aims to counter this gendered bias by connecting the Mobility

Spatial and temporal coordination of air-high speed rail (HSR) intermodal networks is important to reduce emission, improve service, enhance efficiency, and reduce costs in the provision of air-HSR integration. This paper constructs a hierarchical optimisation model that first considers a spatial scope to solve the problem of route allocation and frequency choice which minimises total environmental

Recent discussions on public transport as public space are particularly relevant in transit-oriented cities, where urban design profoundly shapes connectivity and pedestrian flow. Strategies such as destination consolidation, node manipulation, and privatized infrastructure, including walkways and transit systems, significantly influence these patterns. Assimilating ideas from nudge and practice theories

Assessing the coverage of metro stations is crucial for evaluating and guiding metro construction. Existing methods mainly rely on surveys to obtain the coverage radii by fitting the first-mile distance distribution of metro passengers, which is costly and time-consuming to capture the spatiotemporal heterogeneity at the urban scale. Daily generated multi-source mobility data offers the possibility

Origin-Destination (OD) flow, as an abstract representation of the object's movement or interaction, has been used to reveal the movement patterns of human activities and the coupling process of the human-land system. As a developing spatial analysis method, OD flow clustering can be used to identify the dominant trends and spatial structures of urban mobility. However, urban flow exhibits universal

In recent years, the 15-minute city has gained prominence as a vision for urban development, aiming to create attractive and vibrant neighborhoods where essential services are within a 15-minute walk. However, its implementation raises concerns about socio-spatial segregation, as the potential increase in desirability of these neighborhoods—combined with various underlying factors—can lead to increased

The concept of ‘distance decay’ curves is used in spatial interaction and accessibility analysis to represent the diminishing likelihood of visiting places with increasing travel impedance, mainly distance and travel time. The shape of the resulting impedance decay curves varies by several factors, but these influential factors are often dismissed in favor of just travel mode. In this study, we examine

Establishing a charging network is critical to support vehicle electrification. Determining the ideal locations of charging stations can be challenging due to conflicting stakeholder constraints. This study aims to identify the optimal number of on-route charging locations that can support the projected maximum charging demand of long-haul electric vehicles (LHEVs) in the Canadian province of Ontario

Transit ridership has long been studied, and the findings are elucidated by Taylor and Fink (2003) when they say, “to sum, transit ridership is largely, though not completely, a product of factors outside the control of transit managers.” Other than transit fare price, few studies have looked with much scrutiny at the factors that are within the purview of transit agencies. Transit service provision

The generation of daily activity patterns (DAPs) has gained considerable attention due to its capacity to capture the interdependencies among activities and underlying behavioural dynamics. Existing clustering methods often face limitations related to the aggregation of heterogeneous DAPs, leading to reduction in prediction accuracy. This study presents a novel hybrid approach that integrates “direct

Urban supply chain efficiency relies heavily on the location of logistics facilities in metropolitan areas and their proximity to the receivers of goods. This research uses centro-graphic metrics and spatial statistics to research the behavior of warehouses in the Greater Golden Horseshoe Area in Canada in the last decade. The research reported in this paper has four main results. First, it identifies

The impact of traffic on air quality has prompted many cities to implement policies such as driving and parking restrictions, congestion fees, or investing in public transport infrastructure. This paper focuses on the effects on pollution levels of a new cable car system in Mexico City, a very polluted megalopoly. This cable car system provides transportation to historically marginalized communities

Providing diverse modes of travel facilitates people's access to jobs, healthcare, critical activities, and other services. To assess the equity of access to transportation services, it is essential to consider different travel modes. In this study, we propose a concept called “multi-modal deserts” and develop an approach to identify them. Multi-modal deserts refer to areas with limited mobility options

Using data from Southern California, we examine the idea that rising housing prices in transit-rich neighborhoods contributed to pre-COVID declines in transit use. We merge ridership data from the Los Angeles region’s two largest transit providers with tract-level Census data on housing costs and other socioeconomic attributes. We show descriptively that a small share of Census tracts account for a

Newly constructed transport infrastructure may have varying socioeconomic effects across cities and regions. This study employs a spatial equilibrium model to examine how the development of expressways and high-speed rails (HSRs) may induce changes in employed residents, housing rents, and consumer surplus within China's Yangtze River Delta region. Empirical findings indicate limited effects of transport

Before 2018, Saudi Arabia was the only country that enshrined a legal prohibition on women driving. However, little has been done to empirically investigate the associations between female commute cost and labor supply before the driving ban was lifted. This is largely due to the data scarcity on disaggregated-level female mobility patterns and travel behaviors. To fill the gap, this study deployed

This study investigates the geographic and annual variations in carbon dioxide (CO2) emissions and fuel consumption generated by private vehicles across Australia's regions over an 18-year period (2002 to 2020). We examine the influence of vehicle numbers, geography, and time on emissions and fuel consumption using spatial analysis alongside panel regression. Emissions remain relatively high in North

Transportation economics studies show that the activity density, in particular, employment density, is influenced by availability and quality of transportation infrastructure and services, including public transit. These studies also show that businesses and economic activities may have unique requirements, preferences, and characteristics, which may lead to varying effect of transportation on different

In this paper we use complex network analysis to describe fossil fuel spatial flows among 132 places covering the entire United States in 2017 and in 2022. These spatial flows are for crude petroleum, gasoline, and oil fuels. The analysis shows that all three fuels have different network topology. For all six networks we find major hubs of crude petroleum and its products, gasoline and fuel oils, concentrated

Empirical studies of logistics location choice have largely focused on logistics as a single sector. This research attempts to address this research gap by analysing the heterogeneity in locational preferences of logistics across facility types and sizes. We estimate a multinomial logistic regression model to study the relative impact of various spatial drivers on logistics development in the Netherlands

Over the past two decades, the Canadian Arctic has experienced a marked reduction in sea ice extent, coinciding with a significant rise in ship traffic. This study explores the relationship between ship traffic, shipping accidents, accident rates, and diminishing sea ice from 1990 to 2022 during the shipping season. The findings reveal that ship traffic has increased substantially along major Arctic

Often promoted by planning and transportation authorities as one of the principal ways to reduce the impact of mobility on transportation gas emissions, carpooling practices have increased over recent decades for daily commuting as well as long-distance travel. However, mainly due to the lack of data, little is known about the geography of these trips. On the one hand, the intensity of supply and demand

Several countries have implemented designated school zones and installed traffic calming measures to enhance the safety of vulnerable pedestrians near schools. While macro-level built environment attributes (e.g., land use) have been widely acknowledged in relation to the role they play in urban traffic safety, the effects of micro-level streetscape characteristics on crash frequency have not been

There has been a global increase in investment in rail transit, driven by its potential to enhance transportation efficiency, reduce air pollution, and stimulate economic growth. Both cross-sectional studies and natural experiments have contributed to the growing body of evidence supporting these claims. While natural experiments are commonly preferred for evaluating the impact of rail transit, cross-sectional

In contemporary societies, public transportation holds paramount significance for fostering sustainable and equitable urban development. Concurrently, innovative mobility solutions, such as the integration of on-demand mobility services like Demand Response Transit (DRT) and Transportation Network Companies (TNC) with Fixed Route Transit (FRT) systems, are gaining prominence. On-demand mobility, with

Decades of research indicate that accessibility plays a fundamental role in the urban systems of cities by influencing land markets and household location choices. Accessibility is also often positioned as a policy tool in enhancing the well-being of disadvantaged population groups. Considered together, recent research into transportation equity underscores the need to critically investigate the distribution

Statistical modeling of ridership over both space and time provides valuable insights on transportation planning and policies. Existing spatiotemporal studies, however, predominantly focus on analyzing a single type rather than multiple types of ridership, thus cannot leverage the correlation between different types of ridership. This study proposes a Bayesian multivariate spatiotemporal statistical

Transport equity, which emphasises fair and equitable distribution to reach various significant activities and opportunities such as work and healthcare, has greatly interested researchers and practitioners. Enhancing first-mile and last-mile travel and commuting experiences augment an individual's travel satisfaction. However, challenges with first-mile and last-mile travel lead to social exclusion

The COVID-19 has led to significant changes in urban travel behaviors, with commuting being one of the most affected travel modes. Commuting cycling by bike-sharing systems (BSS) is regarded as a new transportation mode that is low-carbon and low-cost. However, its dynamic changes and spatiotemporal characteristics in different periods of COVID-19 still lack exploration. Therefore, this study adopts

Globally, women encounter physical and social barriers that challenge their mobility. This review explores the barriers affecting women's mobility, in the first- and last-mile stretches, in low- and middle-income countries and their consequences on accessibility, availability, affordability, and acceptability of public transport. This review includes 42 studies on mobility, accessibility, safety, travel

Bus and metro are the two primary modes of public transportation in many megacities worldwide. Understanding their cooperation is crucial for the integration of the public transportation system. Despite extensive research on public transportation demand, studies focusing on bus-metro cooperation remain limited. Intermodal transit demand directly reflects the level of cooperation between the two modes

This paper explores the travel behavior of older adults in comparison to younger adults using the 2017 U.S. National Household Travel Survey Georgia Add-on. We employ a discrete mode choice model to examine how the relationships between travel outcomes and socioeconomic, trip, and built environment characteristics vary by age. Travel modes are categorized into automobile, public transit, and non-motorized

The high penetration of e-activities (e-working, e-shopping, e-leisure) has empowered people to overcome space-time constraints in daily routines, and this trend is growing. Accordingly, new knowledge is sorely needed to incorporate e-activities into accessibility planning and to define new conceptualizations, methods, and quantifiers that recognize digital and in-person accessibility in real life

Accessibility is a widely used concept across various disciplines to evaluate the degree to which individuals can reach desired destinations. Conventionally, accessibility is determined by the attractiveness of a destination and the associated travel cost to reach it. However, existing place-based accessibility measures do not differentiate between destinations accessible to individuals from a single

Although the transport assimilation experiences of various East-to-West immigrant groups have been studied, those of international students have received little attention. This study explores the transport assimilation process of Hong Kong students in Taiwan, with a focus on their transition from a public transport-orientated society to one centred on motorcycles. Data were collected through secondary

Street classification is crucial in urban and transportation planning. Conventional approaches prioritize car movement, while recent ones emphasize sustainable modes like walking, cycling, and public transport. However, the literature on sustainable street classification remains limited. Hence, this study aims to develop a method for reformulating and evaluating street classification in an urban municipality

This paper extends previous research that has examined the impact of banning (super) short-haul flights on climate change. Looking at all scheduled passenger flights worldwide, our results confirm that policies focused on super short-haul flights would have very limited climate benefits. Flights of less than 500 km account for 26.7 % of flights but only 5.2 % of fuel burnt, while flights of 4000 km

Walking is essential for environmentally friendly transport, vibrant street life, and public health. Due to the short distances, small cities should have great potential for walking; however, the car still dominates in many places. Moreover, whether and how conditions related to a Northern European location play a role in perceived walkability and subsequent walking behaviour in small cities has rarely

Transportation accessibility, or the ease of reaching valued destinations, is a critical determinant of a person's ability to satisfy their essential needs. A lack of accessibility can result in travel burdens such as high transportation costs or unmet needs and adversely affect well-being. Prior research establishes the inverse relationship between travel burdens and access to transportation options

The recent developments in regionalization have redefined the concept of jobs-housing relationship, calling for reexaminations from the regional perspective. This paper studies the temporal and spatial features of jobs-housing relationship and their relations with regional mobility and regional structure in 2258 Quxians (urban districts or rural counties) across China based on 49 months of cellular

The rapid growth of dockless bike-sharing services (DBSs) in recent years has provided a new potential technological solution to the critical last mile problem of urban mobility and is thus considered a complement to public transit. However, there is little causal evidence of such technology-enhanced DBSs complementing public transit. To address this research gap, this paper empirically investigates
