Summary
This document outlines the research agenda and strategic vision of the U.S. Department of Transportation’s (USDOT) Intelligent Transportation System (ITS) Program, with a primary focus on connected vehicle technologies. The program aims to transform the national multimodal surface transportation system by leveraging advanced wireless technologies to maximize safety, mobility, and environmental performance. The core vision involves creating a connected environment where vehicles, infrastructure, and passengers’ portable devices communicate continuously to share data, thereby enabling transformative changes in transportation operations. The USDOT’s research framework is structured around three main pillars: Connected Vehicle Applications, Policy and Institutional Issues, and Technology. Under applications, the program investigates Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications to enhance safety by providing drivers with 360-degree awareness of hazards, such as blind-side vehicles or sudden braking. For mobility, the Data Capture and Management (DCM) program focuses on generating high-quality, real-time multimodal data to help traffic managers assess system performance and develop Dynamic Mobility Applications (DMA) that optimize traffic flow. Environmental research, specifically the Applications for the Environment: Real-Time Information Synthesis (AERIS) program, evaluates how connectivity can reduce greenhouse gas emissions and improve air quality by minimizing unnecessary stops and encouraging fuel-efficient travel choices. Additionally, road weather applications utilize connected data to forecast and mitigate weather impacts on roadways. Beyond applications, the program addresses critical policy and institutional challenges, collaborating with industry stakeholders, manufacturers, and governments to develop a robust policy foundation that weighs benefits against risks. Technological research focuses on establishing standards for interoperability, system security, and scalability, while also addressing human behavior complexities and driver workload risks. The document also highlights short-term intermodal research initiatives, including Active Traffic Demand Management (ATDM), Intelligent and Efficient Border Crossings, and Commercial Vehicle Information Systems and Technologies (CVISN), which aim to improve safety, productivity, and regulatory efficiency. Furthermore, an Exploratory Research portfolio engages the public through technology scans and innovation challenges to identify emerging solutions. The significance of this guide lies in its comprehensive approach to integrating research with deployment support. Through cross-cutting programs such as the National ITS Architecture, professional capacity building, and international collaboration, the USDOT ensures that research findings translate into practical implementation. The document serves as a roadmap for stakeholders, emphasizing that the successful deployment of connected vehicles requires not only technological advancement but also coordinated policy development, data management strategies, and continuous evaluation to realize the full potential of a safe, efficient, and environmentally sustainable transportation network.
