Functional analysis of web-based GIS tools for environmental justice assessment of transportation projects

Spriggs, A.M.S. (author), Rotman, Robin (author), Trauth, Kathleen (author)

Environmental justice – the concept that environmental amenities and burdens should be shared equitably among all races and socioeconomic classes – has gained diplomatic traction internationally, and political traction domestically in the United States, in recent years. In this paper, we focus on developing federal policy relevant to...

Tao, W. (author), Zhu, Man (author), Chen, Shengyong (author), Cheng, Xu (author), Wen, Yuanqiao (author), Zhang, Weidong (author), Negenborn, R.R. (author), Pang, Y. (author)

Vessels sailing in a single platoon could reduce resistance from the perspective of the whole platoon and the individual vessel, and contribute to improving energy benefits. Moreover, transportation energy costs and traffic efficiency are essential indicators for measuring waterborne transportation systems. We attempt to minimize...

Lock congestion relief in a multimodal network with public subsidies and competitive carriers: a two-stage game model

Yang, Lijuan (author), Lin, X. (author), Li, Eldon Y. (author), Tavasszy, Lorant (author)

Transshipment can be a detour for carriers to bypass congested locks. Therefore, the local government provides subsidies to carriers reluctant to adopt transshipment due to high costs. Using the Three Gorges Dam (TGD) as the subject, we address the interaction between the government and carriers and the rational routine choice for carriers...

Assessing the evolution of educational accessibility with self-avoiding random walk: insights from Helsinki

Aydin, N.Y. (author), Yigitbasi, Emre (author), Casali, Y. (author), van Wee, G.P. (author)

Rapid urbanization has posed challenges to accessibility to critical services that require in-depth analysis. Complex networks theory has been used to evaluate the evolution of network topologies or the overall accessibility of transportation systems. However, topological metrics to explain the temporal changes in accessibility levels do not...

Distributed Dynamic Coordination Control for Offshore Platform Transportation Under Ocean Environmental Disturbances

Du, Zhe (author), Negenborn, R.R. (author), Reppa, V. (author)

Transportation of a large offshore platform from inland waters to the open sea is a hazardous and challenging mission. With the development of the autonomous surface vessel (ASV), the problem of large floating object transportation has a chance to be solved by applying multiple physical-connected autonomous tugboats. This article proposes a...

Methods for increasing the potential of integration of EV chargers into the DC catenary of electric transport grids: A trolleygrid case study

van der Horst, Koen (author), Diab, I. (author), Chandra Mouli, G.R. (author), Bauer, P. (author)

The traction substations of urban electric transport grids are oversized and underutilized in terms of their capacity. While their over-sizing is an unfortunate waste, their under-utilization creates the major hurdle for the integration of renewables into these grids due to the lack of a base load. Therefore, integrating smart grid loads such...

An Adaptive Battery Charging Method for the Electrification of Diesel or CNG Buses as In-Motion-Charging Trolleybuses

Diab, I. (author), Eggermont, Rik (author), Chandra Mouli, G.R. (author), Bauer, P. (author)

The decarbonization of urban bus fleets can be made by their electrification as in-motion-charging (IMC) buses which can run as trolleybuses or in battery mode. The benefit is that IMC buses can use the existing trolleygrid infrastructure where their route overlaps with it to charge the battery and operate in battery mode outside of it....

Multi-Graph Convolutional-Recurrent Neural Network (MGC-RNN) for Short-Term Forecasting of Transit Passenger Flow

He, Yuxin (author), Li, L. (author), Zhu, X. (author), Tsui, Kwok Leung (author)

Short-term forecasting of passenger flow is critical for transit management and crowd regulation. Spatial dependencies, temporal dependencies, inter-station correlations driven by other latent factors, and exogenous factors bring challenges to the short-term forecasts of passenger flow of urban rail transit networks. An innovative deep...

Suitability indices for assessing functional quality of urban surface water

van der Meulen, E. S. (author), van Oel, P. R. (author), Rijnaarts, H. H.M. (author), Sutton, N. B. (author), van de Ven, F.H.M. (author)

Urban surface waters are used in many different ways. With increasing demand for human use functions, improved insight is required into the functional quality of these waters. A method to assess this functional quality in a systematic way and for a wide variety of use functions is not available. We propose to use suitability indices (SIs) for...

How to split the costs and charge the travellers sharing a ride? aligning system's optimum with users’ equilibrium

Fielbaum, Andres (author), Kucharski, R.M. (author), Cats, O. (author), Alonso-Mora, J. (author)

Emerging on-demand sharing alternatives, in which one resource is utilised simultaneously by a circumstantial group of users, entail several challenges regarding how to coordinate such users. A very relevant case refers to how to form groups in a mobility system that offers shared rides, and how to split the costs within the travellers of a...

Multi-stage optimal design of road networks for automated vehicles with elastic multi-class demand

Madadi, B. (author), van Nes, R. (author), Snelder, M. (author), van Arem, B. (author)

With the advent of automated vehicles (AVs), new infrastructure planning concepts such as subnetworks of AV-ready roads have been proposed to improve the performance of transportation networks and to promote the adoption of AVs. However, these subnetworks should evolve over time in response to the growing AV demand, which necessitates a multi...

Planning station capacity and fleet size of one-way electric carsharing systems with continuous state of charge functions

Huang, Kai (author), An, Kun (author), Correia, Gonçalo (author)

This paper presents a method for determining the deployment of one-way electric carsharing services within a designated region that maximizes the total profit of the operator. A mixed integer non-linear program model is built, with a strategic planning level that decides the fleet size and the station capacity and an operational level that...

Serious games as research instruments – Do’s and don’ts from a cross-case-analysis in transportation

Freese, M. (author), Lukosch, Heide (author), Wegener, Jan (author), König, Alexandra (author)

Serious games as research instruments are seen as a special type of participatory modelling, allowing a researcher to observe the behaviour and decisions taken by players. Yet, games have their own dynamics and come with certain challenges when used as a research instrument. This article reports on specific challenges in using games as...

Multi-train trajectory optimization for energy-efficient timetabling

Wang, P. (author), Goverde, R.M.P. (author)

This paper proposes a novel approach for energy-efficient timetabling by adjusting the running time allocation of given timetables using train trajectory optimization. The approach first converts the arrival and departure times to time window constraints in order to relax the given timetable. Then a train trajectory optimization method is...

Beyond Polycentricity: Does Stronger Integration Between Cities in Polycentric Urban Regions Improve Performance?

Meijers, E.J. (author), Hoogerbrugge, M.M. (author), Viseu Cardoso, Rodrigo (author)

A quarter of the European population lives in 'polycentric urban regions' (PURs): clusters of historically and administratively distinct but proximate and well-connected cities of relatively similar size. This paper explores whether tighter integration can increase agglomeration benefits at the PUR-level. We provide the first comprehensive...
