Demographic forecasts indicate that the world population will reach nine billion by 2050, with 70 percent living in urban areas. One challenge resulting from such population growth is an increasing need for high quality mobility solutions. Another is related to logistics and supply chain management. The 4th NYUAD Transportation Symposium will provide a forum for learning about recent developments in smart cities, traffic modeling, control, and logistics and supply chains with the aim of addressing challenges of fast urbanization, as well as the emergence of new technologies and data sources.

Increased computing power and the explosion of data have created opportunities for the OM profession to analyze data to identify new models and approaches to drive decisions and actions. In this talk, we develop a real-time resource deployment approach to match supply/capacity with demands, incorporating multiple and possibly conflicting objectives in the system. In this way, we relate the service performance of the supply chain with the resources/capacities needed at each stage, based on the optimal allocation policy deployed. We show that a data-driven approach can be used to guide the system to allocate resources so that the performance attained has the smallest deviation away from a utopia point for the system. We evaluate the performance of this approach using synthetic data, and also data from a ride-sharing company.

This talk will discuss opportunities and challenges related to the development and application of operations research techniques to transportation and logistics problems in humanitarian and non-profit settings. Much research has been conducted on transportation and logistics problems in commercial settings where the goal is either to maximize profit or to minimize cost. Significantly less work has been conducted for non-profit applications. In such settings, the objectives are often more difficult to quantify since issues such as equity and sustainability must be considered, yet efficient operations are still crucial. This talk will present several research projects that introduce new approaches tailored to the objectives and constraints unique to non-profit agencies, which are often concerned with obtaining equitable solutions given limited, and often uncertain, budgets, rather than with maximizing profits.

Further increasing urbanization and changing customer expectations in e-commerce and last-mile delivery pose disruptive challenges to the design and operation of logistics systems for metropolitan areas, in parts reversing what was believed to be optimal designs for urban logistics for a long time. To address these challenges, various technological and organizational solutions are currently developed and implemented. The success and diffusion of solutions will heavily depend on the availability, analysis and use of smart data to make the best matches between supply and demand in a dynamically changing environment of logistics 4.0
The presentation highlights ongoing research on data-driven logistics analytics for the design and operation of urban logistics from the perspective of different stakeholders. New organizational concepts like crowd-logistics and platform solutions as well as multi-tier city logistics concepts will be discussed and the potential of artificial intelligence and machine learning be investigated.

We study network models where flows cannot be split or merged when passing through certain nodes, i.e., for such nodes, each incoming arc flow must be matched to an outgoing arc flow of identical value. This requirement, which we call no-split no-merge (NSNM), appears in railroad applications where train compositions can only be modified at yards where necessary equipment is available. We propose modeling approaches to represent the NSNM requirement. In particular, we give a linear formulation of the requirement on a single node that describes the convex hull in a lifted space. We present a cut-generating linear program to obtain valid inequalities in the original space of variables, and introduce a polynomial-time procedure to lift strong inequalities of lower-dimensional models into strong inequalities of the original model. In addition, we identify an exponential family of facet-defining inequalities that can be separated efficiently. To evaluate our results computationally, we study a stylized unit train problem. We compare a solution approach based on our results with one that relies on column generation. We then show that our results significantly reduce relaxation times and gaps when compared to leading commercial branch-and-cut software.

Flight scheduling, fleet assignment, and aircraft routing are the three most prominent decisions in airline planning as they contribute towards a majority of the costs and revenues of an airline company. These decisions have to be made 10-12 weeks prior to the flight date as mandated by labor unions in order to accommodate cabin crew scheduling requirements. In this study, we develop a two-stage stochastic programming model for the integrated flight scheduling, fleet assignment, and aircraft routing problem. We extend the model to include propagated delay, which is a serious matter to consider in airline planning because it results in huge costs and inefficient utilization of aircraft and crew. Additionally, codeshare agreements were considered to test the effect of expanding the airline's outreach network while retaining low costs. Sample average approximation (SAA) algorithm is used to tackle the uncertainty in the demand while column generation is used to solve the resulting highly complex problem. Computational experiments conducted on a real-life airline company's flight network show that modeling the stochastic problem with 100 scenarios is sufficient to capture the effect of demand and fare uncertainty and to provide a solution with an optimality gap less than 1% within a reasonable computational time. Furthermore, the results show that column generation can solve the model in a fraction of the time a commercial solver takes. A sensitivity analysis on different parameters of the model was carried out and points out the applicability of the proposed model and solution in practice.

This talk investigates Lagrangian (mobile) control of traffic flow at large scale (city-wide, with fluid flow models) and local scale (vehicular level).
For large scale inference and control, fluid flow models over networks are considered. Algorithms relying on convex optimization are presented for fusion of static and mobile (Lagrangian) traffic information data. Repeated game theory is used to characterize the stability such flows under selfish information patterns (each flow attempting to optimize their latency). Convergence to Nash equilibria of the solutions is presented, leading to control strategies to optimize the network efficiency.
At local scale, the question of how will self-driving vehicles change traffic flow patterns is investigated. We describe approaches based on deep reinforcement learning presented in the context of enabling mixed-autonomy mobility. The talk explores the gradual and complex integration of automated vehicles into the existing traffic system. We present the potential impact of a small fraction of automated vehicles on low-level traffic flow dynamics, using novel techniques in model-free deep reinforcement learning, in which the automated vehicles act as mobile (Lagrangian) controllers to traffic flow.

I am the William Patterson Junior Professor chair at Northwestern's Department of Civil and Environmental Engineering since 2014 and a faculty affiliate of the Transportation Center and Spatial Intelligence and Learning Center. Before this, I was a research fellow at EPFL and I received my Ph.D. in Transport Economics from the University of Trieste in 2012.
My lab studies 'human' aspects of sustainable mobility systems with a focus on transformative sharing and on-demand systems. We develop data-collection tools and develop innovative models to understand the lifestyles, values, and attitudes of citizens and communities that participate in these new techno-social systems. My research typically combines methods including discrete choice and other behavioral modeling, statistical analysis, factor analysis, and other unsupervised learning methodologies, qualitative data collection such as focus groups, as well as large-scale surveys and network data. The lab is engaged both in developing methods to collect data and in specifying mathematical models of behavior that can account for factors that are not dealt with in economic choice models (such as social determinants, environmental concern, user experiences/engagement, simplified decision rules).
The continuous transformation of innovative mobility services prompts the research community to revisit existing travel demand model formulations. The evolving mobility landscape includes bike-sharing (including dock-less), car and scooter-sharing and short-term rental, ride-sourcing with sharing options and e-hailing, and crowd-shipping, with automation on the horizon. These emerging mobility solutions are likely to, over time, alter vehicle ownership, urban travel dynamics, and patterns of land use, generate new markets and economic opportunities and affect mobility externalities. This talk explores user-motivations and functioning of innovative mobility services drawing on micro to large-scale data.
This research will enable smarter designs of emerging systems to maximize acceptance and trigger their positive potential linked to decreasing emissions, promoting multi-modality and transforming urban systems.

The talk will be divided into two parts. During the first part, we will provide a general overview of the European Project TRANS-FORM "Smart transfers through unravelling urban form and travel flow dynamics". It is a cooperation between universities, industrial partners, public authorities, and private operators, that aims to develop, implement, and test a data driven decision making tool to support smart planning, and proactive and adaptive operations. The objective of the project is to better understand transferring dynamics in multi-modal public transport systems and develop insights, strategies, and methods to support decision makers in transforming public transport usage to a seamless travel experience by using smart data.
The second part of the talk will "zoom in" a specific aspect of the project: the management of pedestrian flows. Exploiting the full potential of pedestrian infrastructures in order to satisfy the demand induced by public transport modes is key to achieving good level-of-service for passengers during transfers. High temporal variability in demand can lead to high congestion and possibly dangerous situations while the infrastructure is underused moments after. In order to improve the level-of-service experienced by pedestrians, two management strategies will be investigated.

She is a member of the scientific council of technology companies such as Gran Data, PTV and the Pecan Street Project consortium.
I present a review on research related to the applications of big data and information technologies in urban systems. Data sources of interest include: Probe/GPS data, Credit Card Transactions, Traffic, and Mobile Phone Data. I present a multi-city study to unravel traffic under various conditions of demand and translate it to the travel time of the individual drivers. First, we start with the current conditions, showing that there is a characteristic time that takes to a representative group of commuters to arrive to their destinations once their maximum density has reached. While this time differs from city to city, it can be explained by the ratio of the vehicle miles traveled to their available street capacity. We identify three states of urban traffic, separated by two distinctive transitions. In the second part, I present Computational Social Science methods that use Credit Card Transactions to Uncover different habits on social groups, based on their mobility, their communication and daily purchases. Finally, I suggest how to use these methods to enhance the behavioral changes and recommendations in Social Networks to improve Cities.

New general purpose technologies developed in the categories of machine intelligence, distributed ledgers, and the internet of things (IoT) have launched our global society onto a digital path. These technologies are still new and inchoate. Even so, individuals, companies, and governments are rapidly thrust into circumstances requiring decisions that will influence how a digital society develops without a complete understanding of how the interaction of these technologies will develop. Mobility, or how individuals have moved around, is one of the first areas to be materially changed by these new technologies. In this presentation, I will discuss the mobility-related issues policy-makers, executives, and researchers should be addressing to ensure we end up in a sustainable version of possible digital societies in which all of us want to live.

Transportation is undergoing deep and significant transformation, seeking to fulfill the promise of connected mobility for people and goods, while limiting its carbon footprint. Autonomous vehicles are potentially changing the economics ownership and use of private automobiles, likely accelerating trends towards greater use of app-based ride hailing and/or sharing by private TNCs (Transportation Network Companies). Several potential business models with varying degrees of ride sharing and public vs. private involvement in the delivery of mobility as a service are presented. Algorithms for shared autonomous fleet management are discussed and illustrated. These are integrated in an intermodal dynamic network modeling framework, which incorporates an agent-based microsimulation of a transit urban network system with shared-ride autonomous vehicles (SAV) as first-mile feeders. The integrated mode choice and dynamic traveler assignment-simulation modeling framework is applied to the Chicago region to evaluate the mobility impact of new services. Implications for the evolving role of public transit in the future urban mobility landscape are discussed.

His research interests focus primarily on transport planning and operations, particularly in the areas of highway traffic, public mass transit and systems that jointly serve multiple travel modes.
Discussion focuses on ways of metering vehicle inflows to cordoned neighborhoods, to reduce vehicle hours traveled (VHT). Means entail the re-timing of ordinary traffic signals that reside along the peripheries of those neighborhoods. Metering rates for those peripheral signals are optimized with the aid of neighborhood-wide traffic models, as is now popular in the literature. The first part of the presentation describes how the neighborhood models can be adapted in a simple way that adds physical realism. Computer simulations show that the adapted models produce time-varying cordon-metering rates that are more effective in reducing neighborhood VHT. The second part of the presentation explores how the cordon-metering plans can be further improved with machine-learning techniques. Reinforcement Learning is used to redistribute spatially-uniform rates generated by an adapted neighborhood traffic model, such that metering rates optimally varying along the length of a cordon line.

The Macroscopic Fundamental Diagram (MFD), and its multimodal extension, the 3D-MFD, have received significant attention over the last few years. However, our ability to predict either of them in the presence of limited information or complete absence of empirical data is still quite limited. In this presentation, we will discuss multiple complementary techniques and research findings that can inform the shape of the 3D-MFD for different levels of information availability.

A high-resolution (HR) data system for an intersection collects the location (lane), speed, and turn movement of every vehicle as it enters an intersection, together with the signal phase. Some systems also provide video monitoring; others measure pedestrian and bicycle movements; and some have vehicle to infrastructure (V2I) communication capability. The data are available in real time and archived. The data are processed to produce important performance metrics; compressed to provide a compact description of the trends in traffic; and to predict the traffic several hours into the future. Lastly, a suite of algorithms is described to generate good signal control schemes. Empirical results are presented to illustrate the use of HR data.
