Commuting research often assumes that commuting is a daily grind that elicits stress and strain for travelers. Some scholars have identified evidence that supports the benefits of commuting, but research into this aspect is still relatively limited and does not make a strong connection with the body of works that view commuting as a stressor. This paper offers a more nuanced understanding of commuting

Investment in urban public transportation involves strategic decisions regarding the organization of transit lines in the urban space and the choice of their technology in addition to the size of both fleet and vehicles of each line, and their spacing (lines density). The parametric city model (PCM) of Fielbaum et al. (Transp Res Part B Methodol 94:298–338; Netw Spat Econ 17:343–365) was created to

Unmanned Aerial Vehicles (UAVs) have become integral to numerous applications, prompting research towards enhancing their capabilities. For time-critical missions, minimizing latency is crucial; however, current studies often rely on sending data to ground station or cloud for processing due to their limited onboard capacities.

In many cities, shared micromobility services (SMMS) have become popular. These services contribute to the popularity of car-alternative mobility by promoting the use of micro-vehicles. Bike-sharing and e-scooter-sharing systems are examples of these services. Despite their potential, the share of SMMS is still marginal. To unlock their full potential, policymakers and service providers need to comprehend

Given the increasing concerns about energy consumption and rising consumer social responsibility, firms producing brown products should consider transitioning to greener alternatives that are less harmful to the environment. To examine this, we employ a Stackelberg model to analyze the price and quality of brown and green products (e.g., gasoline and electric vehicles) across three product-line strategies:

Low-carbon technology sharing (LTS) is often viewed as a positive factor for enterprise operations, which can not only encourage the spread of low carbon technologies but also serve as a source of financing for capital-constrained manufacturers. However, it is not clear how LTS works in a capital-constrained supply chain. This study incorporates LTS into the design of supply chain finance schemes,

Micro-mobility is an emerging mode of urban transportation, particularly for its potential to reduce private car use and build sustainable cities. Bikes and electric bikes (e-bikes) are two common types of micro-mobility. Previous studies mainly analyzed the two types separately, failing to provide a comparative and systematic investigation of shared dockless bike/e-bike systems in different cities

This paper investigates a reliable ship fleet planning problem with the uncertainties of container shipping demand, transport costs and freight rates in liner shipping services, and this problem is formulated as a two-stage robust optimization model. In our model, the first-stage decision is to determine the types and quantities of ships, as well as their allocation to different routes, and the second-stage

This study investigates the disclosure strategies for quality information in a dual-channel supply chain comprising a manufacturer and a dual-purpose online platform focusing on both profit and consumer surplus. We elaborate on two disclosure formats: the P-C format, in which the platform discloses quality information, and the M-C format, in which the manufacturer discloses quality information. The

This study investigates a two-echelon supply chain comprising a retailer, who considers whether to sell products as online-exclusive (products available only online) versus hybrid (products available both online and offline), and a supplier, who considers whether to encroach the online market. Given that there are more product varieties online than offline and competitive online marketplace, it remains

Truck platooning is a promising technology for reducing energy consumption, increasing vehicle safety, and improving traffic efficiency. In this paper, we examine the cost-effectiveness of truck platooning from the perspective of a freight company fulfilling full truckload pickup and delivery requests over a transportation network. During transportation, trucks can form platoons on the traversed road

Container shipping demands are usually classified into long-term contract demands from large shippers and ad hoc demands from spot shippers. Compared with stable long-term contract demands, spot container shipping demands are often unstable due to their high frequent cancellations during the slot booking period and their uncertain arrivals even no-shows. This poses a challenge for shipping companies

Logistics service affects product sales and therefore plays a vital role in influencing the selling mode strategy. We investigate how two types of logistics service, namely third-party service and platform service, impact the selling mode choice between reselling and agency selling. We identify that the platform’s commission rate and product-service efficiency jointly shape the selling mode strategy

This study investigates an on-demand first-and-last-mile ridesharing service (FLRS) problem considering the time-dependent travel time for an operator who manage a heterogeneous vehicle fleet. The operator, aiming to minimize the total operational cost, needs to simultaneously serve both first-mile (FM) and last-mile (LM) trips around a public transportation hub, such as a metro station. To holistically

Massive COVID-19 vaccination can significantly reduce both mild and severe infection rates. Some governments have adopted mobile vaccination vehicles, offering a more convenient and flexible service compared to static walk-in sites.

This paper investigates two fundamental questions related to safety and insurance in the age of automation. First, we touch upon the question of safety and liability under infrastructure-assisted automated driving. In such an environment, automakers provide vehicle automation technology while infrastructure support service providers (ISSPs) provide smart infrastructure services. Additionally, customers

In maritime data collection scenarios, due to the constraints of wireless communication and environmental factors such as wave motion, sea surface ducting effects, and sea surface curvature, floating sensor nodes are unable to establish direct data transmission links with the base station. The advent of unmanned aerial vehicle (UAV)-assisted Maritime Internet of Things (MIoT) provides a feasible solution

This paper addresses yard template generation problem in automated container terminals when the vessel arrival schedule is uncertain. Since the yard is central to terminal operations, yard management directly affects the efficiency of most equipment. Yard template functions as a tactical-level yard management strategy, allocating yard space to vessels that call at the port on a weekly basis. By analyzing

Trade-in and resale programs are increasingly adopted by retail platforms, boosting sales and generating additional profits through the resale of used products. Consequently, manufacturers selling new products on these platforms should re-evaluate their selling strategies (wholesale or agency). We construct a game-theoretic model to examine when a retail platform should introduce trade-in and resale

The security issues in Vehicle Ad Hoc Networks (VANETs) are prevalent within Intelligent Transportation Systems (ITS). To ensure the security of vehicle-to-infrastructure (V2I) communication, extensive research on V2I authentication has been conducted in recent years. However, these protocols often overlook the limitations of communication range, leading to failures in V2I communication. Consequently

The profit-oriented bike-sharing industry, such as Mobike in China and Limebike in the USA, has widely adopted the free-float mode, which allows users to rent and return bikes without any restrictions with regard to stations. Compared to the traditional station-based mode, this new mode improves convenience and satisfies a variety of travel demands, but it also results in higher operating costs and
