Abstract: Transportation-related air pollution, GHG emissions and energy problems are a significant issue in the U.S. and across the world. The World Health Organization estimates that urban air pollution causes 200,000 deaths per year worldwide. How do we meet the mobility needs in urban transitions without sacrificing environment sustainability and global health? In this talk Dr. Gao takes a systems approach to study the nexus of transportation and environment/health systems. We’ll examine the broad spectrum and necessary depth of models, tools, and insights for trans-disciplinary systems research in support of integrative transportation, environment, and health systems planning and finance/policy innovation such as public private partnership.

Prediction/Causality Tradeoffs and Data Size Issues in Transportation Modeling: The Example of Highway-Safety Analysis

Fred Mannering
Associate Dean for Research, College of Engineering
Professor of Civil and Environmental Engineering
University of South Florida

 Abstract: The analysis of transportation data is largely dominated by traditional statistical methods (standard regression-based approaches), advanced statistical methods (such as models that account for unobserved heterogeneity), and data-driven methods (machine learning, neural networks, and so on). In the analysis of highway safety data, these methods have been applied mostly using data from observed crashes, but this can create a problem in uncovering causality since individuals that are inherently riskier than the population as a whole may be over-represented in the data. In addition, when and where individuals choose to drive could affect data analyses that use real-time data since the population of observed drivers could change over time. This issue, the size of the data (which can often influence the analysis method), and the implementation target of the analysis imply that analysts must often tradeoff the predictive capability (dominated by data-driven methods) and the ability to uncover the underlying causal nature of crash-contributing factors (dominated by statistical and econometric methods). However, the selection of the data-analysis method is often made without full consideration of this tradeoff, even though there are potentially important implications for the development of safety countermeasures and policies. This talk provides a discussion of the issues involved in this tradeoff with regard to specific methodological alternatives, and presents researchers with a better understanding of the trade-offs often being inherently made in their analysis.

Deployable Decentralized Routing Strategies using Envy-Free Incentive Mechanisms for Connected and Autonomous Vehicle Environments

Srinivas Peeta
Frederick R. Dickerson Chair and Professor,
School of Civil and Environmental Engineering,
H. Milton Stewart School of Industrial and Systems Engineering
Georgia Institute of Technology

Abstract: Routing strategies using dynamic traffic assignment have been proposed in the literature to optimize system performance. However, challenges have persisted in their deployability and effectiveness due to inherent strong assumptions on traveler behavior and availability of network-level real-time traffic information, and the high computational burden associated with computing network-wide flows in real-time. To address these gaps, this study proposes an incentive-based decentralized routing strategy to nudge the network performance closer to the system optimum in a traffic system with connected and autonomous vehicles (CAVs). The strategy consists of three stages. The first stage incorporates a local route switching dynamical system to approximate the system optimal route flow in a local area based on vehicles’ knowledge of local traffic information. This system is decentralized in the sense that it only updates the local route choices of vehicles in this area to circumvent the high computational burden associated with computing the flows on the entire network. The second stage optimizes the route for each CAV by considering individual heterogeneity in traveler preferences (e.g., the value of time) to maximize the utilities of all travelers in the local area. Constraints are also incorporated to ensure that these routes can achieve the approximated local system optimal flow of the first stage. The third stage leverages an expected envy-free incentive mechanism to ensure that travelers in the local area can accept the optimal routes determined in the second stage. They prove that the incentive mechanism is expected individual-rational and budget-balanced. The study analytically shows that the proposed incentive-based decentralized routing strategy can enhance network performance and user satisfaction in a connected and autonomous traffic environment.

The Various Silver Linings of the Impacts of the Pandemic on Traffic

Fraser Shilling
Co-Director, Road Ecology Center
University of California, Davis

In US states, mitigation of the spread of COVID-19 has been implemented by cities, counties, and governors’ offices through “shelter-in-place” and “stay-at-home” orders and related actions. The Road Ecology Center carried out three primary types of investigation into the traffic reduction that resulted from these orders and the corresponding “silver linings” that emerged for driver safety, climate change, and nature.
Traffic Safety: Using observations of reported traffic incidents in our real-time “California Highway Incident Processing System” (CHIPS), the Road Ecology Center found a ~50% reduction in injury and non-injury crashes, on state highways and rural roads that resulted from Governor Newsom’s “shelter in place” order, from ~1,000 crashes and ~400 injury/fatal crashes per day to 500 and 200 per day, respectively. These reductions have resulted in a savings to the public of about $40 million/day, or $1 billion since the order went into effect.
Climate Change: In the US, transportation, including personal vehicles, releases about 29% of the greenhouse gas (GHG) per year. We found that estimated emissions had declined by >50% following the various government stay-at-home orders. This puts the US on track to meet its annual goals for GHG reduction under the Paris Climate Accord.
Impacts to High traffic volume is a primary contributor to wildlife-vehicle conflict (WVC) and wildlife mortality on roads. Using traffic and collision data from four US states (California, Idaho, Maine, and Washington), we found a 34% reduction in WVC. This reduction in mortality would potentially equate to 10s of millions fewer vertebrates killed on US roadways during one month of traffic reduction, representing an unintentional conservation action unprecedented in modern times.

Bio: Fraser received his Ph.D. from USC and has three main project areas in transportation ecology: 1) finding out how environmental disruptions (e.g., climate change, pandemics) impact transportation and other systems, 2) studying how traffic noise and light impacts wildlife use of habitat and wildlife crossing structures, and 3) studying the interaction of transportation systems with natural processes. He is the lead organizer for the International Conference on Ecology and Transportation (ICOET) and co-organizer of the Global Congress on Linear Infrastructure and the Environment (inaugural congress in 2021).

Dynamic Driving and Routing Games for Autonomous Vehicles on Networks: A Mean Field Game Approach

Xuan (Sharon) Di
Associate Professor, Department of Civil Engineering and Engineering Mechanics, Smart Cities Center, Data Science Institute
Columbia University in the City of New York

Abstract: As this era’s biggest game-changer, autonomous vehicles (AV) are expected to exhibit new driving and travel behaviors, thanks to their sensing, communication, and computational capabilities. However, a majority of studies assume AVs are essentially human drivers but react faster, “see” farther, and “know” the road environment better. We believe AVs’ most disruptive characteristic lies in its intelligent goal-seeking and adapting behavior. Building on this understanding, we propose a dynamic game-based control leveraging the notion of mean-field games (MFG). Prof. Di will first introduce how MFG can be applied to the decision-making process of a large number of AVs. To illustrate the potential advantage that AVs may bring to stabilize traffic, she will then introduce a multi-class game where AVs are modeled as intelligent game-players and HVs are modeled using a classical non-equilibrium traffic flow model. Last but not the least, she will talk about how the MFG-based control is generalized to road networks, in which the optimal controls of both velocity and route choice need to be solved for AVs, by resorting to nonlinear complementarity problems.

Bio: Xuan (Sharon) Di is an Associate Professor in the Department of Civil Engineering and Engineering Mechanics at Columbia University in the City of New York since September 2016 and serves on a committee for the Smart Cities Center in the Data Science Institute.

Cross Border Transportation and Environmental/Health Issues

Dr. Henry Van

Visiting Professor of Civil Engineering,

The University of Texas at El Paso

Abstract: In this presentation, Dr. Henry Van discussed Cross Border Transportation and Environmental/Health Issues in the El Paso/Juarez Metroplex area, focusing on multifaceted, complex challenges involving very congested traffic with long wait times going from Mexico to the U.S. or vice versa. The border crossing in the El Paso/Juarez area is the same as the other major border crossings in Nogales, San Diego, and Matamoros. Critical transportation problems cause significant financial losses to major manufacturers operating in Mexico transporting products bound for the United States. Commercial and automobile traffic congestion also causes air pollution at the crossings which has become a significant health issue for people living adjacent to these border crossings.

Building Trust to Enhance Preparedness: An Analysis of Community Perceptions

Johanna Amaya Leal
Department of Supply Chain Management
Iowa State University Ivy College of Business

Even though communities are considered a critical responder after disasters, the subject of community perceptions and trust in response agencies have not received much attention in preparedness research. This study seeks to fill this gap by analyzing how the attitudes and perceptions of individuals in potentially disaster-impacted communities, as well as their socio-economic characteristics, can affect both the roles of trust in emergency response agencies, and risk perception in disaster preparedness.
Usually, organizations developing the necessary preparedness and response plans do not have a clear idea of citizens’ perceptions of the response system, and how these perceptions will/can influence their level of preparedness. Knowing such perceptions would allow communities to engage in the decision of what they need instead of being passive receptors of what is sent to them in case of extreme events. This interaction will positively impact the practice community and will support their effort in building local capacity.
A structural equation modeling approach is used to analyze data from a survey applied to individuals located in towns affected by two different disasters in Colombia. The results suggest that trust in response agencies is mostly influenced by previous experience in disaster situations, education, and income. However, while females have a higher risk perception, they prepare less, even after testing for mediation. Interestingly, for two individuals with the same level of education, the one with a higher income trusts more in the response system. In the same context, for two individuals with the same level of income, the one with higher education trusts less. The seminar will close with a set of recommendations for response agencies, recommendations that take into account the perceptions of the different segments of the population to be served, so that the effectiveness of preparedness efforts and overall level of preparedness of the community increases.

Considering Technology and Resilience in the Florida Transportation Plan

Jim Halley, A.A.E., ACE
Florida Department of Transportation,
Office of Policy Planning
Statewide Planning Coordinator

Technology is constantly evolving and changing the way people interact with one another, work, do business, travel, and even how they buy groceries. New and emerging technologies offer the potential for a safer, more efficient transportation system; more connectivity globally and locally; and streamlined business practices. However, increased reliance on technology brings other challenges to the forefront like cybersecurity and data privacy. Transportation partners need to make wise decisions today to prepare for this future.

Natural hazards, cyberattacks, and other events can have significant and unexpected impacts on Florida. Simultaneously, trends such as sea level rise and global economic shifts can lead to progressive challenges. These events and trends can result in unanticipated transportation system disruptions and increasing constraints on infrastructure, impeding access to reliable mobility. The impact on the lives of residents and visitors and the flow of business and trade can be extensive. It is critical to prepare Florida’s transportation system to be adaptive in the face of these events and trends. Planning for resilience leverages our understanding of potential hazards to mitigate risk, make wiser investment decisions, and provide more reliable transportation.

Safety in Numbers for pedestrians and bicyclists: Implications for public policy

Peter Jacobsen
Professional Engineer

That motorists are a lot less likely to hit someone walking or bicycling if more people walk or bicycle surprised researchers. In contrast, the number of car crashes increases proportionally with the number of cars. The evidence of a prevalence effect implies that injury risk is more than just a matter of physics, and that something occurs with human physiology or psychology. Safety in Numbers likely occurs because humans have difficulty detecting rare items. That injury risk decreases with more walking and biking creates opportunity for implementing public policies for reducing damage to the climate and improving health. This non-linear risk also explains why the recent NTSB recommendation for compulsory bicycle helmet laws could increase injury risk.

Health Co-benefits of Active Transportation for Greenhouse Gas Mitigation

Neil Maizlish
Visiting Researcher
Department of Human Ecology, UC Davis

Background: The Integrated Transport and Health Impacts Model (ITHIM) is a scenario-based risk assessment tool that quantifies the health benefits and harms of physically active travel (walking and cycling), road traffic injuries, and fine particulate air pollution in urban transportation systems.
Methods: Descriptive statistics on travel patterns, physical activity, traffic injuries, and car emissions were derived from statewide travel and health surveys, collision databases, and outputs from regional travel demand and emissions models. The change in disease burden was measured in deaths and disability adjusted life years (DALYs) based on dose–response relationships from meta-analyses and the distributions of physical activity and traffic injuries. Alternative scenarios were measured against baseline travel patterns experienced in each major California region. Alternative scenarios included increases in active travel from baseline to 20 median minutes/person/day, apportioned entirely to walking (“all walk”), cycling (“all cycle”), and or transit-related active travel (“all transit”). The health benefits and greenhouse mitigation of these scenarios were compared to those of the preferred scenarios regional transportation planning agencies. These agencies are mandated to demonstrate greenhouse gas reductions in their transportation plans (“Sustainable Communities Strategies (SB375)”, which emphasize transit expansion to achieve this goal.
Results:The preferred scenarios increased statewide active transport from 41 to 54 min/person/week, which was associated with an annual decrease of 890 deaths and 15,053 DALYs. The ambitious, maximal alternatives increased population mean travel duration to 283 min/person/week for walking, bicycling, or transit and were associated a reduction in deaths and DALYs from 2.5 to 10 times greater than the California preferred scenarios. The alternative with the largest health impact was bicycling, which led to 8,349 fewer annual deaths and 141,597 fewer DALYs, despite an increase in bicyclist injuries. With anticipated population growth by 2040, no alternative achieved decreased carbon emissions, but bicycling had the greatest potential for slowing their growth.
Conclusions: Expansion of transit confers important health benefits through active transport and meets important societal goals for destination accessibility. However, expansion of walking and cycling, independently of transit, can play a larger role in improving population health.

Heterogeneous traffic flow: how agent interactions shape collective properties 

Jia Li
Texas Tech

Collective properties of traffic flow, such as its equilibrium, aggregate dynamics and stability, are determined by attributes of agents (i.e. drivers/vehicles) as well as how the agents interact. Understanding connections between the two is crucial to control and operations, e.g. towards designing mechanisms to make mixed traffic flow of autonomous and human-driven vehicles self-organize and self-stabilize. In this talk, Jia Li presented recent research in this direction. In the first part, Li provided an explicit characterization of equilibriums attainable by heterogeneous traffic flow in multilane settings, where one class of agents are “type-sensitive”, a property that autonomous vehicles may likely be endowed with. In the second part, Li presented simulation evidence along with a heuristic analysis towards explaining spontaneous platoon formation in heterogeneous traffic flow and the role of opportunistic agent behaviors. Finally, Li discussed implications of these results from a control perspective.
