Aim of the Workshop

Public debate about the future of mobility and transportation is increasingly informed by predictions about the impact of Connected, Autonomous and Electrified Vehicles (CAEVs). As CAEVs are approaching market-readiness and are beginning to be deployed, there are still several socio-technical challenges to be addressed. Many of those are being identified as research topics in control systems, for instance:

  • How can we design profitable and sustainable mobility systems that leverage CAEVs?
  • What are the socio-technical challenges we are facing and how can control engineers contribute to address them?
  • How should we adapt our infrastructure to adequately accommodate future autonomous, connected and electrified mobility systems, whilst leveraging existing transportation modes?
  • How can we ensure that such technologies benefit all members of society, improving equity and fairness rather than undermining them?
  • How can we ensure that such technologies are leveraged to help meet sustainability goals?

This workshop will gather experts from control systems, transportation, mechanical, electrical, computer and civil engineering, robotics, and social science in order to:

  1. identify challenges and opportunities in control systems for the future of transportation that are triggered by the advent of CAEVs,
  2. identify modeling and control methodologies to address them,
  3. share insights from early deployments and turn such insights into an actionable research roadmap.

From a technical perspective, we will discuss socio-technical and control problems from the individual vehicle-level up to the transportation-system-level, ranging from human-robot interaction to incentive and tolling schemes, and from network control problems to the combination of new (and old!) technologies within sustainable and human-centered mobility systems. Overall, the goal of the workshop is to provide researchers in control with an overview of current and future mobility challenges to be addressed by our community, and, at the same time, exchange new research results, ideas and visions on how our control community can contribute to sustainable and human-centered mobility systems and, ultimately, our society.

Intended Audience and Expected Outcomes

This workshop is geared towards researchers in control and mobility, industry practitioners, and public officials whose work involves the design, deployment, operation, or regulation of mobility systems. The workshop will present a variety of control challenges, tools and studies that underpin future transportation systems and will hopefully prompt fruitful conversations from the variety of stakeholders in such a monumental transformation of our transportation infrastructure, ultimately providing inspiration and new, transdisciplinary research ideas to our control community.

Tools for Trustworthy: Human Modeling, Behavior Prediction, and Intuitive Inference
Autonomous systems, such as self-driving cars, are becoming tangible technologies that will soon impact the human experience. However, the desirable impacts of autonomy are only achievable if the underlying algorithms can handle the unique challenges humans present: People tend to defy expected behaviors and do not conform to many of the standard assumptions made in robotics. To design safe, trustworthy autonomy, we must transform how intelligent systems interact, influence, and predict human agents. In this talk, I'll present recent efforts on developing trustworthy autonomy that predicts likely human behaviors in "robust" ways and on how we can infer and incorporate hidden states (e.g., driver traits, pedestrian intent, occluded agents) into our predictions for improved downstream decision-making. These methods are used to generate safe interactions between humans and mobile robots (sometimes with guarantees), which are demonstrated on fully equipped test vehicles and mobile robots.

Data and experimental applications of the I-24 MOTION testbed to CAEV research
This presentation will describe applications of the I-24 MOTION open road testbed to the fields of traffic control and connected and automated vehicle research, leveraging the testbed's full roadway visibility and vehicle trajectory computation. The I-24 MOTION testbed is led by the Tennessee Department of Transportation and Vanderbilt University on Interstate 24 near Nashville, TN. The purpose of the testbed is to provide an open road experimental facility for testing traffic management and automated vehicle technologies in real freeway traffic. During normal operation of the testbed, it also provides an unprecedented amount of anonymized vehicle trajectory data that can be used to unlock new traffic science, safety improvements, and driver modeling. The testbed consists of nearly 300 pole-mounted 4K resolution video cameras providing uninterrupted coverage of the roadway. Video data is processed by a computing cluster in real time into vehicle trajectories for all vehicles passing through the testbed. The length of the testbed is 4 miles, leading to an annual generation of 200 million vehicle miles of driving data.

Automating vehicle lane changing and cooperation compliance
We present an optimal control framework for a Connected Automated Vehicle (CAV) and cooperating neighboring CAVs to carry out lane change maneuvers consisting of a longitudinal phase where the CAV properly positions itself relative to the cooperating neighbors and a lateral phase where it safely changes lanes. The optimal policies ensure that the fast-lane traffic flow is minimally disrupted (through a properly defined metric) and that highway throughput is improved by optimally selecting the cooperating vehicles.

We show that analytical solutions for the optimal trajectories can be derived and are guaranteed to satisfy safety constraints for all vehicles involved in the maneuver. We also address the question: “if vehicles include human drivers that make decisions to cooperate or not in such maneuvers, how can we ensure that they are cooperation compliant?” We propose a general framework for such cooperation compliance that avoids explicit incentives or pricing schemes.

Operating a Shared-ride Automated Mobility-on-Demand Service with Walking Legs and Virtual Stops
Decreasing fleet vehicle distance traveled per customer served in mobility-on-demand (MOD) services has become a regulatory goal and an operational challenge for service providers. Compared to ride-hailing MOD services where vehicles serve passenger trips sequentially, shared-ride MOD services can serve multiple traveler requests simultaneously. However, shared-ride services also incur detours when routing to/from traveler origins and destinations on minor arterials and local streets. To address this shortcoming, a few MOD service providers and several researchers propose having travelers walk a short distance from their origin to a pickup location and from a drop-off location to their final destination.

We propose a modeling and solution approach for the highly complex dynamic vehicle routing problem associated with the shared-ride automated MOD service with walking legs operational problem, where the operator decisions include i) assigning traveler requests to vehicles, ii) assigning traveler requests (and their assigned vehicles) to pickup and drop-off locations, iii) sequencing pickups and drop-offs for requests assigned to a vehicle, and iv) scheduling the pickups and drop-offs. To address this stochastic and dynamic problem for a large vehicle fleet (2000+ vehicles), we introduce and compare novel optimization-based operational policies that sequentially solve the four decision problems in different orders. Finally, we test the operational policies in a high-fidelity, high-resolution agent-based transportation system model, known as POLARIS, where network congestion is endogenous and travel times are stochastic.

Two birds with one stone: optimal approximation for integral routing and congestion pricing
Motivated by fleet management in autonomous mobility, we consider the classical problem of minimizing total congestion in integral multicommodity routing, and, more generally, in congestion games.  For this well-known class of problems, we present a comprehensive set of results providing tight hardness of approximation and a polynomial time algorithm with optimal approximation. As the algorithm we propose is based on the utilization of carefully designed taxes, our work shows, perhaps surprisingly, that indirect interventions are as good of a mechanism in approximating the optimal allocation as any other centralized approach. Three technical contributions underpin this conclusion. First, we show that minimizing the total congestion is NP-hard to approximate within a given expression depending solely on the class of admissible resource costs. Second, we design a tractable taxation mechanism whose efficiency (price of anarchy) matches the hardness factor. As these results extend to coarse correlated equilibria, any no-regret algorithm inherits these same performances, allowing us to devise polynomial time algorithms with optimal approximation. We conclude by showing that, although worst-case, the approximation factors we obtain are near optimal (i.e., close to one) for many real-world instances of interest.

15:00 – 15:30

Mahnoosh Alizadeh

Ride Pricing and Competition in Autonomous Mobility on Demand Platforms
In the first part of the talk, we will look at the joint routing, battery charging, and pricing problem faced by a profit-maximizing transportation service provider that operates a fleet of autonomous electric vehicles. We will showcase the potential benefits of our real-time policy for optimizing dynamic ride prices jointly with routing and charging decisions and its effectiveness in controlling customer wait times for rides. In the second part of the talk, we discuss the effect of competition between profit maximizing ride operators, where we present new mathematical models of platform competition and discuss universal lower bounds for the effect of competition on customers' surplus and the platforms' profits.
