This project aims to develop a robot (xBOT) that is customized for testing autonomous-connected vehicles. xBOT itself would be an automated-connected robot that behaves, and be perceived, as a free-moving Pedestrian, Scooter, Bicycle, Motorbike, or full-sized Vehicle. The project’s original intention was to build xBOT by modifying the Segway Ninebo

Safely introducing autonomy to trucks requires monitoring their brake systems continuously. Out-of-adjustment push rods and leakages in the air brake system are two major reasons for increased braking distances in trucks, resulting in safety violations. Air leakages can occur due to small cracks or loose/improperly fit couplings, which do not affec

Vehicle manufacturers are introducing increasingly sophisticated vehicle automation systems to improve driving efficiency, comfort, and safety. Despite these improvements, partially and fully automated vehicles introduce new safety risks to the driving environment. Driver inattention can contribute to increased risk, especially when control transfe

This report documents the work conducted as a multi-disciplinary project on the wireless charging of parked Electrical Vehicles (EVs) by Wright State University and supported by the Ohio Department of Transportation (ODOT). This document summarizes our progress on a wide variety of topics, including 1) in-house software to read and label the open-s

The global electric vehicle (EV) market is forecasted to grow by 24.3% till 2028 constantly. However, the development in charging infrastructure is still lagging behind that, hindering the EV's widespread application, i.e., 30 million chargers are still needed to support the existing EV demand. Also, based on the survey by Witricity, 86% of EV owne

Connected Vehicle (CV) communication technology (i.e., Vehicle-to-Everything, V2X) enables vehicles to "talk" to other vehicles on the road (Vehicle-to-Vehicle, V2V), roadside infrastructure (Vehicle-to-Infrastructure, V2I), vulnerable road users (Vehicle-to-Pedestrian, V2P), and the "cloud" (vehicle-to-network, V2N). The V2X connectivity will prov

Partial- and conditional-automated driving systems (ADS) can not only assist drivers with their driving tasks but also significantly reduce the driving-related burden. Yet still, when the AVS is engaged, the human driver still plays a critical role such as monitoring the driving environment and performing certain driving tasks when called upon by t

The emerging transportation technologies – vehicle connectivity, electrification, and automation – are expected to impact highway expenditures, revenue, and user equity. With regard to the expenditures, the provision of new infrastructure and modification of existing infrastructure will incur significant capital spending. With regard to revenue, th

In the era of connectivity and automation, the prospective vehicular applications of these technologies go beyond transportation operations and traffic management. Connected and automated vehicles (CAVs) are capable of centralized control, information sharing through connectivity, and integrated surveillance. Also, CAVs are readily amenable to inno

The application of on-demand ridesharing services can improve the efficiency and usage of a metropolitan transportation system. Implementing air taxis service can reduce the number of required aerial vehicles, mitigate air pollution, increase the revenue of the transportation network companies, and boost local economics. In this report, we propose

This research aims to develop human data-driven automated lane-change models for freeway weaving sections using computational methods that assist drivers taking an exit ramp or entering a freeway. A naturalistic driving dataset with 108 adult drivers served as the data source to observed drivers’ lane change maneuvers over 53 freeway weaving sectio

The transition of the vehicle fleet to incorporate AV will be a long and complex process. AVs will gradually form a larger and larger share of the fleet mix, offering opportunities and challenges for improved efficiency and safety. At any given point during this transition a portion of the AV fleet will be consuming roadway capacity while unoccupie

The ongoing integration of autonomous vehicles (AVs) into our urban environments represents a fundamental shift in the way cities function and how pedestrians navigate them. Historically, pedestrians have relied on non-verbal cues to interact with human drivers. However, with the rise of AVs, this traditional method of communication is undergoing a

This research aims to develop data-driven models for suggesting the initiation of an automated car-to-bicycle overtaking process that will be assessed subjectively by human drivers and bicyclists in a driving simulator environment. A naturalistic driving dataset with 102 vehicles involved served as the data source for model development. The models

A sustainable transportation future is one in which people eschew personal car ownership in favor of using automated vehicle (AV) based ridehailing services in a shared mode. However, the traveling public has historically shown a disinclination towards sharing rides and carpooling with strangers. In a future of AV-based ridehailing services, it wil

At the current time, road agencies and city authorities are considering various stimuli (legislations, policies, programs, and infrastructure investment projects) to support or facilitate electric, connected, and/or automation vehicle (ECAV) transportation. A candid and comprehensive assessment of such stimuli is possible only after due considerati

Over the past century, landmark advancements in vehicle technology have motivated road agencies to carry out changes in their road infrastructure design and management processes to accommodate these advancements. The advent of Autonomous Vehicles (AVs), however, poses infrastructure challenges that could be more profound compared to those faced in
