Considering traffic safety concerns and challenging driving conditions on Interstate 80 in Wyoming, the United States Department of Transportation (USDOT) and Federal Highway Administration (FHWA) selected an I-80 400-mile freeway corridor as one of the three sites in the United States to develop, test...
Connected and automated vehicle (CAV) driving features can impact traffic safety in many aspects owing to their improved driving behavior. On the other hand, road geometric design elements are mainly based on human reactions and behavior, which might affect safety depending on road layout and the parties...
Connected and Autonomous Vehicle (CAV) technologies enable communication among vehicles, and vehicles and infrastructure, paving the way for multiple safety and operational applications. This research developed and tested traffic signal control algorithms and control programs, which utilized CAV-equipped...
Autonomous Vehicles (AVs) have the potential to offer benefits and flexibility in travel, which can lead to significant reductions in the generalized travel cost and possibly, more demand. The combination of the AV technology with Mobility as a Service (MaaS) creates a new disruptive transportation mode...
This research seeks to develop an infrastructure safety support system by embedding V2I enabled sensor networks into the transportation infrastructure to provide autonomous vehicles and human drivers with inputs to improve their decision making when obvious decisions may not possible. A new car-following...
With the recent increase in connectivity in vehicle technologies, connected vehicles (CVs) offer a number of potential improvements (e.g., safety, mobility, environmental efficiency, etc.) to the existing transportation system. However, to maximize these benefits, sufficient market penetration of CV...
Autonomous vehicles (AVs) that utilize LiDAR (Light Detection and Ranging) and other sensing technologies are becoming more prevalent in the transportation industry. Concurrently, transportation agencies are increasingly challenged with asset management, traffic operations, and safety assessments. The...
While the automobile industry is rapidly transitioning towards automation, the transit industry in the United States has recently begun investigating automation in transit operations. Multiple U.S. transit agencies have been experimenting with various automation technologies in transit vehicles. Examples...
A study investigated the cognitive underpinnings of consumers' beliefs and confidence in their beliefs about fully automated vehicles. Following previous research, opinions about self-driving cars tended to be mixed. The most negative views were held by consumers who had the least knowledge of self-driving...
Automated vehicles promote road safety, fuel efficiency, and reduced travel time by decreasing traffic congestion and driver workload. In a vehicle platoon (grouping vehicles to increase road capacity by managing distance between vehicles using electrical and mechanical coupling) of such automated vehicles...
