While the local construction market has lost its steam in recent years, it is discussed that the overseas construction projects should be activated by using the Official Development Assistance (ODA) in terms of finding a new way. This study empirically identifies the relationship between ODA and the foreign construction orders, and discovers the ef...

This study aims to provide sustainable management strategies for rural communities by examining characteristics of a village hotel, Albergo Diffuso (A.D.), which has evolved through developing sustainable management and adapting to different regional contexts. While A.D. is widely recognized as a sustainable development tool for rural communities u...

The American Automobile Association (AAA) conducted a 1-year pilot study of running a self-driving shuttle bus in the old downtown of Las Vegas between November 1, 2017, and October 31, 2018. Using the 3-year business license data in the City of Las Vegas—1 year before, 1 year during, and 1 year after the operation, this study conducts a generalize...

In general, the same traffic information is provided to all drivers. This study investigated different responses to traffic information based on vehicle type on a local road. A living lab-based experiment was conducted in Seoul, South Korea. This experiment examined changes in approach speed and braking distances of vehicles in response to safety a...

Light Rail Transit (LRT) systems have been introduced across various regions of South Korea to address travel needs and promote sustainable urban development. Jobs-housing balance was one of the top priorities for city management in these schemes. However, a lack of an integrated plan for LRT and jobs-housing opportunities has resulted in excess co...

Introduction: Providing safe road infrastructure is increasingly gaining attention worldwide as part of the effort to reduce road deaths and injuries. Halving road fatalities by 2030 is one of the targets among the Sustainable Development Goals of the United Nations. This study aims to understand how road traffic conditions, including vehicle speed...

The development of public transportation systems, such as Bus Rapid Transit (BRT), has long been associated with changes in residential patterns and property values. However, less attention has been given to how public transit infrastructure impacts business performance, particularly in terms of sales. This study aims to fill this gap by examining...

Sustainability 2025, 17, 628. Abstract: Reducing vehicle lane widths has been proposed as an effective strategy to decrease vehicle speeds and enhance road safety. However,...

This study investigates the relationship among lane width, velocity, and accident rates to enhance understanding their impact on road safety and transportation. Analysis of data from 320 urban arterial sections in Utah indicated that narrower lane widths can improve road safety. Reduced vehicle speeds were related to narrower lanes on urban arteria...

This research investigates the lane width standards and guidelines implemented by various State Departments of Transportation (DOTs) to reduce vehicle speeds and enhance road safety. Lane width reduction is often perceived as a strategy to mitigate speed and improve safety. Still, its effectiveness and implications vary across different contexts, i...

Introduction: Introducing new public transit systems impacts the surrounding built environment, and changes in the built environment can affect travel behavior. Prior research has yet to thoroughly conduct a comprehensive exploration of the influence of new investments in public modes of transit, particularly streetcars, on motor vehicle crashes oc...

One major challenge of a public transit system is first- and last-mile (FLM) connectivity. With the advent of smart technology and on-demand transportation services, shared micromobility is believed to provide a low-cost solution for bridging the first- and last-mile gap. However, several studies have arrived at mixed conclusions about the FLM achi...

This research investigates the lane width standards and guidelines implemented by various State Departments of Transportation (DOTs) to reduce vehicle speeds and enhance road safety. Lane width reduction is often perceived as a strategy to mitigate speed and improve safety. Still, its effectiveness and implications vary across different contexts, i...

Reducing the lane width of urban arterials provides space for different street features, whereas selecting the appropriate lane width considering road safety is a concern. The major elements of this research are: a comprehensive literature review investigating the effects narrower travel lanes and other geometric designs have on speed, safety, and...

The COVID-19 pandemic has brought about significant changes across various sectors of our society. In particular, measures such as mandatory mask-wearing and social distancing have led to substantial reductions in traffic volume, while at the same time, dramatic increases in demands in food delivery orders. The changes in travel patterns have raise...

Despite the growing popularity and benefits of shared dockless e-scooters, there is controversy over whether this is an affordable travel mode for everyone. This paper explores the nonlinear relationship between shared dockless e-scooters and the location affordability of neighborhoods. By analyzing shared dockless e-scooter trip data collected bet...

Conventional corridor management has focused on travel speed and efficiency while ignoring interactions between highway corridors and surrounding areas. This study investigates the interaction between the corridor highway system and the built environment around highways by estimating sustainable mode choices with respect to the land use characteris...

Despite numerous studies on pedestrian safety, research on the impact of the built environment on pedestrian crashes have produced mixed results. This may be due to lack of understanding of exposure and risk factors in the built environment that could influence pedestrian safety. This study investigates the relationship between built environment ch...

Despite the growing popularity and benefits of shared dockless e-scooter, there is controversy over whether this mode is an affordable travel mode for everyone. This paper explores the nonlinear relationship between shared dockless e-scooters and the location affordability of neighborhoods. By analyzing shared dockless e-scooter trip data collected...
