By leveraging advanced technologies, Autonomous Vehicles (AVs) hold the potential to increase transportation safety and efficiency. This collection showcases USDOT-funded research and data concerning AVs. Bookmark this collection: https://rosap.ntl.bts.gov/collection_avs OR https://doi.org/10.21949/1x81-qs91.
Automated Vehicles have been one of the most sought-after concepts to make transportation more effective and safer. No-occupant vehicles with automated driving systems (ADS) make up one such class of vehicles. These are primarily intended for goods transportation services. This vehicle class presents a body structure different than that of a passen

Nearly 1 in 5 people in the US have a disability (more than 57 million) (U.S. Census Bureau), and people with disabilities use the automobile as a travel mode at significantly lower rates than people without disabilities (Bureau of Transportation Statistics). For example, people aged 18 to 64 with disabilities make 28% fewer trips per day (2.6 v. 3

Evaluation of VISSIM revealed that internal modeling of CAV has several limitations. For external modeling, two VISSIM interfaces are useful. The Component Object Model (COM)Application Programming Interface (API) is the superior approach for fetching data and modeling connectivity, whereas the External Driver Model (EDM) is a better tool for later

Recently, 2D detection in images has made significant progress owing to the emergence of a convolutional neural network (CNN), which can extract high-level features from the images. However, detecting objects in 3D instead of 2D space is an essential topic when building perception systems for autonomous driving. An autonomous vehicle (AV) needs to

In 2016, the Valley Metro Regional Public Transportation Authority (Valley Metro) of the Greater Phoenix metropolitan area was awarded a grant as part of the Federal Transit Administration (FTA) Mobility on Demand (MOD) Sandbox program. Through the grant, Valley Metro and Waymo partnered to pilot the use of Waymo autonomous vehicles (AVs) as certif

The deployment of autonomous vehicles (AVs) has been troubled by the soaring cost of operations and the public’s concerns about the safety and fairness issues potentially brought by the new mobility. As leading companies such as Waymo and Uber which have obtained permits to commercialize their robotaxi fleets domestically and overseas, it is urgent

To meet the expectation of multi-modal distributions from customers for last-mile delivery, a sustainable two-echelon E-Grocery delivery system is studied, which is motivated by the adaption of autonomous delivery robot (ADRs), parcel lockers in E-Grocery distribution industry. We formulate the multi-modal last mile system as a two-echelon location

A survey was designed and conducted by inviting various AV industry players to practically answer one prime question "what transportation infrastructure improvements or modifications are needed to improve AV performance?" Based on the survey results, selected AV companies were interviewed. The purpose of the interviews was to have in-depth dialog w

Older adults (>65 years) account for almost 20% of the population in the United States and prefer driving as their primary mode of transportation but are at greater risk for crash-related injuries and death, compared to younger drivers. Autonomous vehicles (AVs) may hold health and safety benefits for older drivers, if this segment of the populatio

Understanding the contributing factors in more than 6 million vehicle crashes that occur annually in the U.S. is very challenging, and police officers investigating crashes need all the tools they can use to reconstruct the crash. Given that the Connected and Automated Vehicle (CAV) era is rapidly unfolding, this study seeks to leverage newly avail

Safety, mobility, accessibility challenges, and dependence on personal vehicles have long plagued rural transportation systems. Benefits in these areas are widely touted by autonomous vehicle (AV) advocates. Seven mechanisms for AV-induced increases in vehicle miles traveled (VMT) are reviewed here, and five of these mechanisms are expected to have

This project has combined tools from geospatial analysis, mathematical optimization theory, and computational geometry to study a routing paradigm that we call sidekick routing. A sidekick routing scheme is a logistical framework in which a large vehicle, such as a truck or van, serves as a mobile base for a fleet of small vehicles (the “sidekicks”

Public transit ridership in California declined in the five years before the pandemic of 2020–21 and dropped significantly further after the pandemic began. A sharp downward step in the level of transit boarding occurred after February 2020, and continues to the date of this report as a result of the public-health guidance on social distancing, exp

Automated, Connected, Electric, and Shared (ACES) technologies are rapidly evolving and will continue to impact development of vehicles, infrastructure, communities, commerce, and the economy. With rapidly evolving technology, it is difficult yet critical to maintain coordination and increase collaboration among research, development, testing, depl

The last mile problem of E-grocery Distribution comprises one of the most costly and highest polluting components of the supply chain in which companies deliver goods to end customers. To reduce transport cost and fuel emissions, a new element of ground-based delivery services, autonomous delivery vehicles (ADVs), is included in the E-grocery distr

The concept of the Michigan Mobility Transportation Facility, now known as Mcity, formed from a recognized need for a safe, controlled environment in which to develop various connected and automated vehicle (CAV) components that included interaction with real-world infrastructure. Therefore, one could say Mcity grew out of necessity; but it has als

This study helps understand how the anticipated emergence of autonomous vehicles will affect various aspects of society and transportation, including travel demand, vehicle miles traveled, energy consumption, and emissions of greenhouse gases and other pollutants. The study begins with a literature review on connected and automated vehicle (CAV) te
