Demand and supply parameters are modeled using fuzzy logic to incorporate the inherent uncertainty of

Shared parking allocation effectively enhances the utilization of parking resources by implementing a staggered sharing system. The price attached to allocated parking spaces plays a crucial role in determining the interests of both the supply and demand sides, as well as the platform involved. Existing models ignore the lost benefits to demanders after secondary or multiple allocations. This paper

This paper presents an approach to use GPS-based travel behavior surveys to determine who is being served well and who is being served poorly by the transport system. We draw on the extensive literature on travel behavior, which has shown that people’s travel behavior is at least in part shaped by the travel barriers they experience. Starting from this basic insight, we define 17 parameters that may

In this study, the transportation network design problem (NDP) is investigated by integrating geometric and topological indices—continuity, regularity, betweenness centrality, and closeness centrality—alongside the traditional total travel time minimization objective. Each index is individually optimized within a bi-level optimization framework, enabling a comprehensive assessment of its impact on

Out-of-school time (OST) activities are essential for students’ educational achievement and workforce development. However, economically disadvantaged youth have far less OST access compared to their wealthier counterparts. In sprawling, low-density metropolitan areas, a lack of reliable and cost-effective transportation services constitutes a considerable barrier to OST participation for youth from

As a newly emerging mode of shared micro-mobility, the e-bike sharing system (EBSS) is increasingly establishing more stations to meet rising user demand. Due to the vast number of stations and the limited space available on urban streets, the operation of the EBSS largely relies on the platform’s battery swapping. This paper, for the first time, models the EBSS battery swapping problem as a variant

This study addresses the problem of robust train composition and carriage arrangement for the mixed transportation of passengers and freights in a high-speed railway (HSR) network. Specifically, a network-based robust optimization (RO) model

Hemodialysis centers use session-based scheduling to provide regular treatments for chronic hemodialysis patients. Optimizing the use of hemodialysis machines is crucial to managing daily patient loads, which requires the timely initiation of parallel sessions. Many centers offer transportation (shuttle) services to ensure punctual patient arrivals. However, post-disaster scenarios pose significant

This paper studies the relative performance of congestion pricing versus tradable permits for a congested bi-modal transport system with traffic externalities, that affect passengers only, and societal externalities that go beyond the passengers. The point in this case is infection risks, as in the pandemic. We study this relative performance for the case where there are uncertainties on both traffic

The COVID-19 pandemic has heightened the need to better understand travellers’ preferences for reduced crowding in public transport. Using panel data from repeated choice experiments with a large sample of Norwegian metro and train users during and after the pandemic, we investigate how the marginal valuation of travel time varies depending on crowding levels and passengers’ positions when sitting

Autonomous vehicles (AVs) may exacerbate traffic congestion due to zero-occupant cruise to avoid parking and save parking fees. Congestion pricing strategies are considered as important solutions to reduce traffic congestion. However, there is still insufficient research on the congestion pricing strategy on zero-occupancy AVs, which we refer to as the cruise pricing strategy. Therefore, this paper

This paper examines the optimal design of dynamic pricing strategies for a coupled ride-hailing market with the coexistence of ridesharing and non-ridesharing services. Riders may switch between ridesharing and non-ridesharing alternatives to maximize individual utility, which results in demand diversion. Due to the imbalance between demand and supply, riders may become impatient towards long waiting

Investigating and simulating the impact of floods on crowd dynamics at evacuation bottlenecks is essential, given the increment of the intensity of these disasters due to climate change.

Under dynamic traffic demand conditions, two issues must be addressed when perimeter control is implemented for congested areas of a road network. The first is to avoid intersection spillback at the boundaries and expansion of the congestion, and the second is to improve the output traffic efficiency of the congested areas to quickly relieve traffic congestion. To address these two issues and solve
