This talk is based on a research study partially supported by an Alibaba Cainiao research grant. We consider the problem of designing a sparse subgraph that supports a large matching after some nodes are randomly deleted. It is motivated by how to balance the trade-off between transportation costs and network complexity in the context of middle-mile delivery operations. We study three families of sparse graph designs (namely, Clusters, Rings, and Erdos-Renyi graphs) and show both theoretically and numerically that their performance is close to the optimal one achieved by a complete graph. We test our theoretical results using real data and conclude that adding a little flexibility to the routing network can significantly reduce transportation costs. This is joint work with Yifan Feng (National University of Singapore), René Caldentey (Chicago Booth), Yuan Zhong (Chicago Booth), Bing Wang (Alibaba Cainiao), and Haoyuan Hu (Alibaba Cainiao).

Increased storm frequency and intensity, increased total precipitation, sea level rise and very high tides are among some of the concerns associated with climate change. With these impacts, more frequent temporary or permanent inundation of transportation system elements can be expected. This has important consequences for economies, needed response capacities and capabilities, and motorist safety. This talk describes a multi-temporal, stochastic optimization-based solution technique for long-term transportation investment planning in protective measures for safeguarding the performance of our roadway networks. The importance of explicitly considering the stochastic nature of future climate impact predictions and predictive accuracy to investment planning and enhanced system resilience is investigated. In events where pre-event investments do not suffice and significant inundation occurs, connectivity of the transportation network may be impacted, affecting the transportation system’s performance, and precluding needed access for restoring transportation services and services of other critical lifelines. This talk introduces a stochastic modeling approach that explicitly consider endogenous uncertainty for the problem of jointly prioritizing post-disaster roadway inspection and restoration actions.

Measuring the degree of competition in markets is important for setting competition and regulatory policy as well as developing management strategies. Commonly used structural indices, such as the HHI, overlook the way in which firms compete and, hence, set their prices in markets. We propose a new horizontal differentiation measure, which encapsulates firms’ portfolio of products as well as the degree of overlap and substitution between competing services. Applied to aviation markets, we term this measure Schedule Differentiation Metric, or SDM, and we demonstrate the significant importance of SDM in explaining price levels and structure.

Mega infrastructure projects, such as High-Speed Rail (HSR), have experienced rapid development in many countries in the world. But how could planners and decision-makers better understand the regional impact of the gigantic system to make rational decision-making for future investment and development remains a challenge. In this presentation, I will discuss the regional impacts of HSR using China as an example. The assessment covers a range of issues, such as land use, real estate, tourism, modal competition, regional economy, and the environment. The objective is to provide lessons learned for transportation planners and decision-makers in India with a holistic perspective to understand the benefits of HSR investment on regional development.

Fast-growing needs for urban mobility are worsening congestion, energy use, and greenhouse gas emissions. At the same time, the sector is being rapidly transformed by on-demand businesses and new vehicle technologies. Long-term sustainable mobility growth requires developing novel technology, business and policy solutions. This talk focuses on two such specific solutions. First, despite their various benefits, ride-hailing platforms like Uber, Ola and Didi have also been associated with increased road congestion and declining public transit ridership. In the first half of this talk we focus on the following question: Can public transit and ride-hailing co-exist and thrive in a way that enhances the urban transportation ecosystem as a whole? We develop a new mathematical model and a novel computational framework optimizing transit schedules, while explicitly accounting for their impacts on road congestion and passenger mode choice. We demonstrate that, through better alignment of transit services with passengers’ preferences and ride-hailing services, transit agencies can lower costs for passengers, operators and the system as a whole—a rare win-win-win outcome.
Second, electric vertical-takeoff-and-landing (eVTOL) vehicles enable a new form of transportation known as Urban Aerial Mobility (UAM). This second half of the talk focuses on optimizing the number, location and capacity of vertiports in a metropolitan area. We capture interdependencies between strategic vertiport deployment, tactical UAM operations and customer adoption. We develop an original exact algorithm based on adaptive discretization and provide a provable solution quality guarantee. Results indicate that the optimal UAM networks vary widely across metropolitan areas, as a function of geographic, urban and commuting patterns. Vertiport networks grow in a nested fashion, starting with a few “obvious” vertiports and adding vertiports as penetration increases. We uncover two potential use cases for UAM technologies: airport shuttle and long-distance commutes.

With the rapid development and popularization of mobile and communication technologies, dynamic ride-sharing platforms, as pioneers in a sharing economy context, provide on-demand shared mobility services and are disruptively changing the transportation industry. First, we study the coordination of platform demand and supply using prices and wages. We use a queueing model with endogenous supply and demand and present steady-state performance in equilibrium to determine the optimal price and wage that maximize the platform’s profit or social welfare. Second, we discuss the matching problem, in which the platforms match passengers and drivers in real-time considering multiple objectives such as platform revenue, pick-up distance, and service quality. We develop an efficient online matching policy and demonstrate its good performance through numerical experiments and implementation using real data.

The international transport of maritime containers employs multiple transport means, such as deep-sea vessels and trucks, or alternatively river barges and train sets. The planning and execution of combined transport operations is challenging, since resources are to be orchestrated efficiently while delivery of service must be reliable.
To address these challenges, the port of Rotterdam and its hinterland have become a living laboratory, where practitioners are performing pilot studies and academics develop new methods to put innovative logistics concepts to the test.
In the presentation, I will discuss how Synchromodal transport solutions offer mobility of freight instead of specific transport capacity. Containers that need to be transported are matched with transport options in a dynamic way. Practitioners have demonstrated the feasibility of the concept, while academics have elaborated on various decision models in support of e.g. network design, capacity planning, and routing. The living lab now progressively involves new modes of transport, such as semi-automated trucks that dynamically form platoons where consolidation is viable.
Advanced planning concepts, where multiple modes of transport are involved, tend to be more data intensive. However, the transportation industry is progressively recognizing the value of data as a strategic asset, not to be shared without compensation. Therefore, a proper understanding of what data is needed to enhance quality of planning is key. In some cases, a marginal improvement of data quality may already help create better prognostics and planning.
