ABSTRACT The European Air Traffic Management Network is unique in its complexity due to numerous stakeholders, airspace configurations and accommodated traffic volumes. Such complexity challenges both tactical visibility and network resiliency in general. Therefore, we review different perspectives of resiliency and robustness to explore advantages of performance variability in understanding network

ABSTRACT At the interface between airport airside and landside operations, the assignment of flights to gates is key to ensure efficient operations and a high quality of service for passengers. We propose a mixed-integer linear program for an integrated flight-to-gate assignment that considers both airside as well as landside constraints on the capabilities of facilities such as check-in, security

It aims to allow at least 50% of passengers to experience the new optimum LOS range while cutting off LOS values during peak and off-peak periods. The simulation also helps to

ABSTRACT Understanding the value of travel time for mobility concepts based on self-driving vehicles is crucial to accurately value transport investments and predict future travel patterns. In this paper, we carry out a morphological analysis to illustrate the diversity of mobility concepts based on self-driving vehicles and the complexity of determining the value of travel time for such concepts.

Both subjective and objective measures of discretionary trips are analyzed. A number of attributes such as smartphone use for different purposes, individuals’ perceptions and attitudes towards smartphone use and travel, and built

ABSTRACT Over the past 20 years, shared-mobility services have become important transportation options, as they provide on-demand, door-to-door mobility without requiring vehicle ownership. Although low-income communities may benefit especially from the services due to their lower vehicle ownership and high dependency on public transit, scant research has been conducted exploring how frequently these

ABSTRACT New mobility services, including carsharing and automated vehicles (AVs), are changing mobility. Gathering evidence on the prospective adoption and uncertainty surrounding new technologies is critical, but technological changes outpace the speed with which planners can inform policy. This study demonstrates the feasibility of bridging planners’ programming and experimentation responsibilities

ABSTRACT Tradable credits for congestion management are a novel policy concept that is receiving increased interest in transportation research. This interest is mainly driven by the belief that the concept can count on stronger social support and hence has a better prospect for implementation than charging-based instruments. This paper is the first to provide an analysis of the social, political, economic

ABSTRACT Parking charges are considered to be a powerful tool for managing transport demand, as parking price is one of the most important factors impacting the travel decision-making process. This paper examines and quantifies the parking price impact on parking demand due to an increase in initial parking price as well as due to the real price decrease (inflation-adjusted) over time. Revealed preference

ABSTRACT Past decades have seen a ‘peak car’ phenomenon which is indicated by a decline in vehicle kilometers traveled (VKT) in many countries. Although the determinants of VKT have been widely discussed, the theoretical arguments remain unresolved, particularly on the role of transport policies, socioeconomic factors and the built environment. This paper aims to contribute to new evidence for these

This study investigates mobility and environmental impacts of CAVs on signalized intersections. With I2V communication capability, CAVs are able to receive the real-time traffic signal

ABSTRACT Algorithms for optimizing traffic operations at a single intersection consider mostly one objective function (often vehicle delays). Such an approach can lead to long pedestrian waiting times as well as reducing safety conditions at the intersection. In this paper, a multicriteria optimization approach to the single intersection traffic control problem is presented. The trade-off algorithm

ABSTRACT Positive impacts of car-sharing, such as reductions in car ownership, congestion, vehicle-miles-traveled and greenhouse gas emissions, have been extensively analyzed. However, these benefits are not fully effective if car-sharing subtracts travel demand from existing sustainable modes. This paper evaluates substitution rates of car-sharing against private cars and public transport using a

ABSTRACT Liberalised railway markets bring into play the economic interactions amongst three dominant interest groups: passengers as system users; public entities providing the track; and private firms operating the trains. Problems that arise are multi-criteria with multi-decision-makers who may be in conflict. Our approach to this problem is similar to that of a cooperative game-theoretic non-transferable

ABSTRACT Where private ridesharing companies such as Uber and Lyft are transforming the transit sector by making flexible transit cheaper and more readily available than ever before, it may be beneficial for public transportation agencies to adapt to the changing marketplace and provide flexible bus services in low to mid-demand density areas such as suburban or rural areas. This paper proposes an

Firstly, the probability of performing different types of activities around transit stops is calculated considering available land use types, distance to stops, and size of related facilities. Secondly, the temporal distribution of sociodemographic

ABSTRACT In the United States, planning and design efforts to generate bike-friendly environments through the greater provision of safe, low-stress bike infrastructure in our cities continue to advance. In Cambridge, Massachusetts, construction of the Grand Junction Pathway – an envisioned shared-use pathway – is at the heart of a citywide effort to enhance its active transportation system. However

ABSTRACT Considerable observational evidence indicates that travel time, averaged across a population, is stable at about an hour a day. This implies both an upper and a lower bound to time that can be expended on travel. The upper bound explains the self-limiting nature of road traffic congestion, as well as the difficulty experienced in attempting mitigation: the prospect of delays deters some road

ABSTRACT Over the last two decades, motorcycle and motorised three-wheeler taxis have become important means of transport in many sub-Saharan African countries, including in rural areas. However, the emerging role of mobile phone technology in improving mobility in rural areas is currently under-explored in the literature.

ABSTRACT In this paper, commuters’ travel mode and departure time choice behaviors on a bottleneck-constrained highway with a peak-only bus lane (PBL) are investigated. The PBL occupies part of the capacity of the bottleneck when it is open. The capacity of the bottleneck for both auto and bus modes is time-varying. As the total number of commuters grows, we consider three regimes with different equilibrium

ABSTRACT The Transit Network Design and Frequency Setting Problem (TNDFSP) can be defined as the creation of effective routes in a public transport network and the determination of relevant frequencies. Generally, the TNDFSP problem is in the same category as the Traveling Salesman Problem (TSP), which is known to be a non-deterministic polynomial-period (NP-hard) difficult problem. This study consists
