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

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

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

As of 2021, there were 18,696 small towns in the US with a population of less than 50,000. These communities typically have a low population density, few public transport services, and limited accessibility to daily services. This can pose significant challenges for residents trying to fulfill essential travel needs and access healthcare. Autonomou

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

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 connected and automated vehicle (CAV) technologies will bring unprecedented changes in the landscape of transportation systems for areas like operations, management, and infrastructure needs. To assure a safe, reliable, and trustworthy connected and automated transportation system, it is important to have a clear CAV implementation pathway that

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

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 study introduces a unified end-to-end framework for analyzing network traffic equilibrium. The framework learns supply and demand components directly from traffic data, using computational graphs to parameterize unknown elements. It enforces user equilibrium through variational inequalities and can incorporate various modeling approaches, incl

Taking advantage of the rapid development of vehicle control and communication technologies, many studies have suggested that operating vehicles in platoons in the future would help improve the safety and efficiency of the transportation system. Although vehicles in a platoon can share data from V2/V communication, a platoon model built on proper c

The number of automated features in surface vehicles is increasing as new vehicles are released each year. Some features allow drivers to temporarily take their attention off the road to engage in other tasks. However, sometimes it is important for drivers to immediately take control of the vehicle. To take control safely, drivers must understand w

Truck platooning—wirelessly linking two or more trucks to travel in a closely spaced convoy—is federally promoted to save fuel, improve the environment, and improve traffic operations. Platooning places trucks much closer than current design codes anticipate. While this strategy can provide higher fuel efficiency, it also can potentially overload s

We will apply our results from neuroscience and safe control to improve driver-assistance technology as follows. First, we will study the use of visual attention information to detect risks early, before the failure to detect risk-critical obstacles can be identified from the drivers' control action and vehicle states. Second, we will find safer co

This paper focuses on assessing the transportation system and sub-population level impacts of different congestion pricing policies for shared AV services in Seattle. While the conclusions of this research are meant to be generalizable, we focus our study on Seattle, Washington because it’s a diverse city with known inequalities among income, race,

Roadway intersections are among the major causes of traffic congestion besides lane reduction bottlenecks. When a major road intersects a minor road at an unsignalized intersection without the control of a traffic signal, the mainline vehicles are given priority over the minor road vehicles to go through the intersection, and the latter can only en

High precision road maps are a crucial component to facilitating autonomous driving techniques. Autonomous vehicles (AVs) are experiencing exponential growth. According to the latest forecast from IHS Markit, over 33 million AVs will be on the road globally by 2040, posing a higher requirement to ensure AVs’ driving safety. Although current AVs rel
