We present a novel statistical inference framework for convex empirical risk minimization, using approximate stochastic Newton steps. The proposed algorithm is based on the notion of finite differences and allows the approximation of a Hessian-vector product from first-order information. In theory, our method efficiently computes the statistical er

Reservation-based traffic control is a revolutionary intersection management system which involves the communication of autonomous vehicles and an intersection to request space-time trajectories through the intersection. Although previous studies have found congestion and throughput benefits of reservation-based control that surpass signalized cont

This report summarizes the results of a study conducted to document the safety and mobility needs of Rural, Isolated, Tribal, or Indigenous (RITI) communities and to identify autonomous and connected vehicle technology that have the potential of addressing these needs. A review of the administrative structure for the five Native American Tribes in

With the advent of automated vehicle systems, the role of drivers has changed to a more supervisory role. However, it is known that all vehicles with Level 2 (L2) systems have a very specific operational design domain (ODD) and can only function on limited conditions. Hence, it is important for drivers to perceive the situations properly and regain

Commuting congestion increases alongside the prosperity of urban cities. With the rapid development of ride sourcing services and the advances of the connected and automated vehicles (CAV), researchers are seeking innovative approaches to alleviate commuting congestion by integrating CAV-based ride sourcing and transit services. We propose a genera

Automated vehicles (AVs) should be deployed gradually and geometrically selectively to ensure safety. Frequent collisions of AVs in certain driving scenarios, such as in dark streets or crowded areas, have posed wide concerns of AV safety. People want to know what kinds of driving circumstances or areas are easy for AVs and what are relatively hard

This study was designed to assess capacity changes due to the introduction of connected vehicles (CVs) and automated vehicles (AVs) on Virginia freeway corridors. Overall, three vehicle types, including legacy vehicles (LVs); vehicles equipped with adaptive cruise control (ACC) (AVs); and vehicles equipped with cooperative adaptive cruise control (

Disruptive changes in mobility services are emerging across the nation and in New York State that have the potential to further enable private car-optional lifestyles and expanded, more flexible and affordable mobility choices. By convening stakeholder engagement roundtables of advanced transportation experts, then utilizing available data for visu

FTA has conducted research on conceptual ideas, prototypes, and commercially available products related to automated vehicle technologies for transit bus operations. The emerging automated transit bus market has received enthusiastic media coverage, but stakeholders may not clearly understand the difference between conceptual ideas, prototype syste

This report presents a study that investigated potential travel behavior changes in light of automated, connected, electric, and shared-use vehicle (ACES) technologies. Three main aspects of choice behavior were investigated: AV adoption and willingness to pay (WTP), shared mobility adoption, and mode choice. Particularly, this study focuses on exp

This research project is intended to track disruptive technologies impacting transportation including automated and connected vehicles, big data analytics, shared vehicles, electric vehicles and novel modes of transportation. The researchers follow industry and technology trends, synthesize research results from the full range of Carnegie Mellon Un

A burgeoning field of research has begun to directly compare the impacts of pairing vehicle automation and connectivity to automation alone. While most recent impact studies that evaluate adaptive cruise control (ACC) and cooperative adaptive cruise control (CACC) rely on traffic simulation, the US Department of Transportation has recently conducte

This study evaluates the potential human health impacts from connected and autonomous vehicles (CAVs) scenarios in the San Francisco, Bay Area. The study concentrates on impacts derived from the effects of CAVs on travel demand, safety, and environmental emissions. The study combines an extensive literature review about the extent of such potential

The increasing number of senior drivers may introduce new road risks due to age-related declines in physical and cognitive abilities. Advanced driver assistance systems (ADAS) have been proposed as solutions to minimize age-related declines, thereby increasing both senior safety and mobility. This study examined factors that influence seniors’ atti

Autonomous vehicles (AVs) at varying market penetration rates will change traffic flow and highway performance. At AV market penetration rates of between 0 percent and 100 percent, human-driven vehicles (HVs) will be interacting with AVs. However, little is known about how HVs interact with AVs. Using the Oregon State University Driving Simulator,

Multiple studies have explored different forms of connected vehicle applications, such as queue warning and cooperative adaptive cruise control (CACC), in standard wireless access in vehicular environments (WAVE), and dedicated short-range communication (DSRC) network environments. A major focus of the ongoing research is to consider a hybrid vehic

The Urbanism Next Center at the University of Oregon, in partnership with Alta Planning + Design, Spirit for Change, and Metro hosted the Future of Public Spaces and Placemaking workshop on January 24th, 2020. This one-day workshop, supported by the Knight Foundation, brought together a wide range of community activists, government officials, polic

Most mid-size and large open-campus universities have courtesy shuttle or bus service as an important mode of transportation around campus and in nearby vicinities. Given on-campus traffic conditions, traffic congestion between classes, the nature of short-distance trips within or around campus, and difficulty with finding parking spaces, automated

The Federal Rail Administration (FRA) Highway-Rail Grade Crossing Inventory database from 2019 states that there are approximately 127,000 public, at-grade highway-rail grade crossings in the U.S. Despite this large number of direct intersections between the public highway and largely private rail systems, little current intelligent transport syste
